I want to keep my pages separately and load them all into one main page using ajax, this way I can change my layouts much quicker. I use Metro UI Css.
Problem is, my page works perfectly when called alone, but when called through ajax and displayed on the main page, it does not respond, or throw any exceptions. This is my html code for the page that is loaded:
<head>
<script src="../../app/webroot/js/jquery/jquery.min.js"></script>
<script src="../../app/webroot/js/jquery/jquery.widget.min.js"></script>
<script src="../../app/webroot/js/prettify/prettify.js"></script>
<script src="../../app/webroot/js/load-metro.js"></script>
</head>
<body class="metro">
<div class="accordion" data-role="accordion" style="font-size:20px; color:#3D5168">
<div class="accordion-frame">
<a class="heading" href="#"><i class="icon-history"></i>Early days</a>
<div class="content">
<p>Line 1</p>
</div>
</div>
</div>
</body>
I suspect that the line
href="#"
has something to do with it, it might be trying to call to the original page that it came from, instead of the page it is actually displayed on. I do all the same imports on the "caller" page, and as I said, I get no exceptions.
This is how I load the page (Ajax)
function LoadPage(PageName)
{
document.getElementById('LoadedPage').style.visibility='hidden';
document.getElementById('loader').style.visibility='visible'
var xmlHttp=MakeConn();
xmlHttp.onreadystatechange = function()
{
if(xmlHttp.readyState === 4)
{
HandleLoad(xmlHttp.responseText,PageName);
}
};
xmlHttp.open("GET", "http://www.somewebsite.com/main/"+PageName, true);
xmlHttp.send(null);
}
function HandleLoad(response,PageName)
{
if(PageName!='home')
{
document.getElementById('home').className = 'tile bg-VSblue1';
}
if(PageName!='games')
{
document.getElementById('games').className = 'tile bg-VSblue1';
}
if(PageName!='about')
{
document.getElementById('about').className = 'tile bg-VSblue1';
}
if(PageName!='contact')
{
document.getElementById('contact').className = 'tile bg-VSblue1';
}
document.getElementById(PageName).className = 'tile double bg-VSblue1 selected';
document.getElementById('loader').style.visibility='hidden';
document.getElementById('LoadedPage').style.visibility='visible';
document.getElementById('LoadedPage').innerHTML = response;
}
Does anyone have some suggestion on how to fix this? Thank you...
This happens because after you called AJAX it wasn't initialized so I won't work. To initialize jst add this line after you place the element in body :
$.Metro.initAll();
That's it now everything will work fine.
Note: If it doesn't try 'initall' instead of 'initAll'

I want home.html to load in <div id="content">.
<div id="topBar"> HOME </div>
<div id ="content"> </div>
<script>
function load_home(){
document.getElementById("content").innerHTML='<object type="type/html" data="home.html" ></object>';
}
</script>
This works fine when I use Firefox. When I use Google Chrome, it asks for plug-in. How do I get it working in Google Chrome?
I finally found the answer to my problem. The solution is
function load_home() {
document.getElementById("content").innerHTML='<object type="text/html" data="home.html" ></object>';
}
Fetch API
function load_home (e) {
(e || window.event).preventDefault();
fetch("http://www.yoursite.com/home.html" /*, options */)
.then((response) => response.text())
.then((html) => {
document.getElementById("content").innerHTML = html;
})
.catch((error) => {
console.warn(error);
});
}
XHR API
function load_home (e) {
(e || window.event).preventDefault();
var con = document.getElementById('content')
, xhr = new XMLHttpRequest();
xhr.onreadystatechange = function (e) {
if (xhr.readyState == 4 && xhr.status == 200) {
con.innerHTML = xhr.responseText;
}
}
xhr.open("GET", "http://www.yoursite.com/home.html", true);
xhr.setRequestHeader('Content-type', 'text/html');
xhr.send();
}
based on your constraints you should use ajax and make sure that your javascript is loaded before the markup that calls the load_home() function
Reference - davidwalsh
MDN - Using Fetch
JSFIDDLE demo
You can use the jQuery load function:
<div id="topBar">
HOME
</div>
<div id ="content">
</div>
<script>
$(document).ready( function() {
$("#load_home").on("click", function() {
$("#content").load("content.html");
});
});
</script>
Sorry. Edited for the on click instead of on load.
Fetching HTML the modern Javascript way
This approach makes use of modern Javascript features like async/await and the fetch API. It downloads HTML as text and then feeds it to the innerHTML of your container element.
/**
* #param {String} url - address for the HTML to fetch
* #return {String} the resulting HTML string fragment
*/
async function fetchHtmlAsText(url) {
return await (await fetch(url)).text();
}
// this is your `load_home() function`
async function loadHome() {
const contentDiv = document.getElementById("content");
contentDiv.innerHTML = await fetchHtmlAsText("home.html");
}
The await (await fetch(url)).text() may seem a bit tricky, but it's easy to explain. It has two asynchronous steps and you could rewrite that function like this:
async function fetchHtmlAsText(url) {
const response = await fetch(url);
return await response.text();
}
See the fetch API documentation for more details.
I saw this and thought it looked quite nice so I ran some tests on it.
It may seem like a clean approach, but in terms of performance it is lagging by 50% compared by the time it took to load a page with jQuery load function or using the vanilla javascript approach of XMLHttpRequest which were roughly similar to each other.
I imagine this is because under the hood it gets the page in the exact same fashion but it also has to deal with constructing a whole new HTMLElement object as well.
In summary I suggest using jQuery. The syntax is about as easy to use as it can be and it has a nicely structured call back for you to use. It is also relatively fast. The vanilla approach may be faster by an unnoticeable few milliseconds, but the syntax is confusing. I would only use this in an environment where I didn't have access to jQuery.
Here is the code I used to test - it is fairly rudimentary but the times came back very consistent across multiple tries so I would say precise to around +- 5ms in each case. Tests were run in Chrome from my own home server:
<!DOCTYPE html>
<html>
<head>
<script src="https://code.jquery.com/jquery-2.1.4.min.js"></script>
</head>
<body>
<div id="content"></div>
<script>
/**
* Test harness to find out the best method for dynamically loading a
* html page into your app.
*/
var test_times = {};
var test_page = 'testpage.htm';
var content_div = document.getElementById('content');
// TEST 1 = use jQuery to load in testpage.htm and time it.
/*
function test_()
{
var start = new Date().getTime();
$(content_div).load(test_page, function() {
alert(new Date().getTime() - start);
});
}
// 1044
*/
// TEST 2 = use <object> to load in testpage.htm and time it.
/*
function test_()
{
start = new Date().getTime();
content_div.innerHTML = '<object type="text/html" data="' + test_page +
'" onload="alert(new Date().getTime() - start)"></object>'
}
//1579
*/
// TEST 3 = use httpObject to load in testpage.htm and time it.
function test_()
{
var xmlHttp = new XMLHttpRequest();
xmlHttp.onreadystatechange = function() {
if (xmlHttp.readyState == 4 && xmlHttp.status == 200)
{
content_div.innerHTML = xmlHttp.responseText;
alert(new Date().getTime() - start);
}
};
start = new Date().getTime();
xmlHttp.open("GET", test_page, true); // true for asynchronous
xmlHttp.send(null);
// 1039
}
// Main - run tests
test_();
</script>
</body>
</html>
try
async function load_home(){
content.innerHTML = await (await fetch('home.html')).text();
}
async function load_home() {
let url = 'https://kamil-kielczewski.github.io/fractals/mandelbulb.html'
content.innerHTML = await (await fetch(url)).text();
}
<div id="topBar"> HOME </div>
<div id="content"> </div>
When using
$("#content").load("content.html");
Then remember that you can not "debug" in chrome locally, because XMLHttpRequest cannot load -- This does NOT mean that it does not work, it just means that you need to test your code on same domain aka. your server
You can use the jQuery :
$("#topBar").on("click",function(){
$("#content").load("content.html");
});
$("button").click(function() {
$("#target_div").load("requesting_page_url.html");
});
or
document.getElementById("target_div").innerHTML='<object type="text/html" data="requesting_page_url.html"></object>';
<script>
var insertHtml = function (selector, argHtml) {
$(document).ready(function(){
$(selector).load(argHtml);
});
var targetElem = document.querySelector(selector);
targetElem.innerHTML = html;
};
var sliderHtml="snippets/slider.html";//url of slider html
var items="snippets/menuItems.html";
insertHtml("#main",sliderHtml);
insertHtml("#main2",items);
</script>
this one worked for me when I tried to add a snippet of HTML to my main.html.
Please don't forget to add ajax in your code
pass class or id as a selector and the link to the HTML snippet as argHtml
There is this plugin on github that load content into an element. Here is the repo
https://github.com/abdi0987/ViaJS
load html form a remote page ( where we have CORS access )
parse the result-html for a specific portion of the page
insert that part of the page in a div on current-page
//load page via jquery-ajax
$.ajax({
url: "https://stackoverflow.com/questions/17636528/how-do-i-load-an-html-page-in-a-div-using-javascript",
context: document.body
}).done(function(data) {
//the previous request fails beceaus we dont have CORS on this url.... just for illlustration...
//get a list of DOM-Nodes
var dom_nodes = $($.parseHTML(data));
//find the question-header
var content = dom_nodes.find('#question-header');
//create a new div and set the question-header as it's content
var newEl = document.createElement("div");
$(newEl).html(content.html());
//on our page, insert it in div with id 'inserthere'
$("[id$='inserthere']").append(newEl);
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<p>part-result from other page:</p>
<div id="inserthere"></div>
Use this simple code
<div w3-include-HTML="content.html"></div>
<script>w3.includeHTML();</script>
</body>```
This is usually needed when you want to include header.php or whatever page.
In Javascript it's easy especially if you have HTML page and don't want to use php include function but at all you should write php function and add it as Javascript function in script tag.
In this case you should write it without function followed by name Just. Script rage the function word and start the include header.php
i.e convert the php include function to Javascript function in script tag and place all your content in that included file.
I use jquery, I found it easier
$(function() {
$("#navigation").load("navbar.html");
});
in a separate file and then load javascript file on html page
showhide.html
<!DOCTYPE html>

<head>
<script type="text/javascript">
function showHide(switchTextDiv, showHideDiv)
{
var std = document.getElementById(switchTextDiv);
var shd = document.getElementById(showHideDiv);
if (shd.style.display == "block")
{
shd.style.display = "none";
std.innerHTML = "<span style=\"display: block; background-color: yellow\">Show</span>";
}
else
{
if (shd.innerHTML.length <= 0)
{
shd.innerHTML = "<object width=\"100%\" height=\"100%\" type=\"text/html\" data=\"showhide_embedded.html\"></object>";
}
shd.style.display = "block";
std.innerHTML = "<span style=\"display: block; background-color: yellow\">Hide</span>";
}
}
</script>
</head>
<body>
<a id="switchTextDiv1" href="javascript:showHide('switchTextDiv1', 'showHideDiv1')">
<span style="display: block; background-color: yellow">Show</span>
</a>
<div id="showHideDiv1" style="display: none; width: 100%; height: 300px"></div>
</body>
</html>
showhide_embedded.html
<!DOCTYPE html>
<html>
<head>
<script type="text/javascript">
function load()

var ts = document.getElementById("theString");
ts.scrollIntoView(true);

</script>
</head>
<body onload="load()">

If your html file resides locally then go for iframe instead of the tag. tags do not work cross-browser, and are mostly used for Flash
For ex : <iframe src="home.html" width="100" height="100"/>
I have a master container php file with a div container. Initially, the div container doesn't have any content or html children by default when page is loaded. I use JQuery to load php files to this div container when the user clicks a navigation item in the navbar.
landingpage.php
<?php
require_once 'navbar.php';
?>
<!DOCTYPE html>
<html>
<head>
<title>Admin | Dashboard</title>
<link rel="stylesheet" href="css/dashboard_admin.css">
</head>
<body>
<div class="wrapper">
<!-- CONTENT CONTAINER's content depends on what was clicked on navbar -->
<div class="container" id="content_container">
<div class="div_dashboardLabel" id="dashboard_Label">
<h2 id="label_Dashboard">Admin Dashboard</h2>
</div>
</div>
<!-- END OF CONTENT CONTAINER-->
</div>
<!-- end of wrapper-->
<script src="js/jquery-3.3.1.js"></script>
<script type="text/javascript">
var user = '<?php echo json_encode($user);?>';
var role = '<?php echo json_encode($role); ?>';
</script>
<script src="js/landingpage.js"></script>
</body>
</html>
landingpage.js
/* GLOBAL VARIABLES WITHIN THIS DOCUMENT*/
var div_content_container = $("#content_container");
var navitem_dashboard = $("#admin_dashboard");
var navitem_admin_account_management = $("#admin_accountmanagement");
var userObj = JSON.parse(user);
var roleObj = JSON.parse(role);
var logout = $('#logout');
/* END */
$(document).ready(function(){
loadDashboard(); // dashboard is loaded as default view.
navitem_admin_account_management.on("click",loadAccountManagement);
});
function loadDashboard() {
var url_admin_dashboard = 'view/admin_dashboard.php';
var url_teacher_dashboard = 'view/teacher_dashboard.php';
var url_student_dashboard = 'view/student_dashboard.php';
div_content_container.html('');
if (roleObj.rolename === 'Administrator') {
div_content_container.load(url_admin_dashboard);
} else if (roleObj.rolename === 'Teacher') {
div_content_container.load(url_teacher_dashboard);
} else if (roleObj.rolename === 'Student') {
div_content_container.load(url_student_dashboard);
}
}
function loadAccountManagement(){
var url = 'view/admin_accountmanagement.php';
div_content_container.html('');
div_content_container.load(url);
}
Everything works as expected for landingpage.php which uses landingpage.js for the front end. No problem.
The problem is when admin_accountmanagement.php file is loaded in div_content_container. The JS of admin_account_management.php doesn't seem to bind to elements:
function loadAccountManagement(){
var url = 'view/admin_accountmanagement.php'; // has its JS file
div_content_container.html('');
div_content_container.load(url);
}
For example, let's take url which is 'view/admin_accountmanagement.php' This page gets loaded within div_content_container when user clicks a navbar item Account Management
as in
<div class="wrapper">
<!-- CONTENT CONTAINER's content depends on what was clicked on navbar -->
<div class="container" id="content_container">
<!-- view/admin_accountmanagement.php loaded here -->
</div>
<!-- END OF CONTENT CONTAINER-->
</div>
There are no problems displaying the page or replacing the current element contained in the div_content_container. The problem is, the JS file attached to view/admin_accountmanagement.php doesn't seem to apply when view/admin_accountmanagement.php page is loaded in div_content_container
The view/admin_accountmanagement.php is loaded but the click events binded to the elements of view/admin_accountmanagement.php doesn't work. I know this because I tried to display an alert() message on $(document).ready()
admin_accountmanagement.php
<body>
<div>
<button class="button" id="btn_AddUser">
Add New User
</button>
</div>
<script src="js/admin_accountmanagement.js"></script> <!-- this JS doesn't seem to get binded when this page is loaded in the div_content_container -->
</body>
admin_accountmanagement.js
var btn_add_user = $('#btn_AddUser');
$(document).ready(function(){
alert("TEST"); //doesn't work no alert message.
btn_add_user.on("click",test); //doesn't work no alert message
});
function test(){
alert("testing"); //doesn't work. no alert message
}
I'm only able to display the page but when I click on the <button id="btn_AddUser"> nothing happens.
How can I solve this given the how I structured the loading of pages to div_content_container?
Thanks in advance.
Change your admin_accountmanagement.js to
var btn_add_user = $('#btn_AddUser');
alert('Account management js loaded'); // this should show alert
$(document).on("click",btn_add_user,test);
function test(){
alert("testing"); //doesn't work. no alert message
}
This method works because the binding is not dependent on "document ready" as document ready has already been fired when you loaded the parent page for the first time
#jordan i agree with #Magnus Eriksson as it is better to bind it on('event','selector','function') but make use of .off() before your .on() as you are playing with dynamic content which may cause multiple binding of the function. And if you are still not able to get the binding event to work you can try injecting the .js file in your page's head section after the load of your content like: $('head').append('<script src="admin_accountmanagement.js"></script>'). With your load() function in your js to bind the click event.
Or, your use the below code snippet:
function LoadContent()
{
var url = 'view/admin_accountmanagement.php';
var jssrc = 'js/admin_accountmanagement.js';
div_content_container.html('');
div_content_container.load(url);
if($('head').find('*[src="'+jssrc+'"]').length==0)
{
//the below approach have some consequences related to it as you will not be able to see the injected js in your developers tool's Sources(in chrome).
$('head').append('<script src="'+jssrc+'"></script>');
}
}
and then on your .js will look like this:
var btn_add_user = null;
$(window).load(function(){
alert("TEST");
btn_add_user = $('#btn_AddUser');
btn_add_user.off('click').on("click",test); //use .off('event') if load() is being called multiple times.
});
function test(){
alert("testing");
}
While converting a script to not require jQuery, I've discovered that if I load my content (a partial html page with html and javascript) via XMLHttpRequest, the javascript in the partial page does not work. But if I load the partial using jQuery.load, it does work.
I've tried digging through jQuery's load function to see if it's doing anything special and nothing jumped out at me. I've been banging my head against the wall and searching for an answer for a couple of days now to no avail.
What am I doing wrong/how can I make it work like it does when loaded with jQuery.load?
EDIT
I got the XMLHttpRequest method to work by splitting out out my javascript from the html in the fragment and loading the javascript using the suggested technique here: https://stackoverflow.com/a/11695198/362958. However, that still does not provide an explanation of why jQuery.load works. Is jQuery umtimately parsing the HTML and doing the same thing for any scripts it finds within the content it loads?
I've set up a plunker (https://plnkr.co/edit/wE9RuULx251C5ARnUbCh) with the following code that demonstrates the issue. Note: once you load the fragment with jQuery, it will continue to work and you'll have to restart the plunk for the XMLHttpRequest method to fail again.

You can use single .html file, and you are on the correct track by splitting the html content - though you can also split the html content of a single file, rather than requesting two files. #Barmar explains the functionality of jQuery's .load() method at this comment.
script.js
function loadXMLDoc(targetDivName, url) {
var xmlhttp = new XMLHttpRequest();
xmlhttp.open("GET", url, true);
xmlhttp.onreadystatechange = function() {

if (xmlhttp.status == 200) {
// create a `div` elemenent, append response to `div` element
// get specific elements by `id`, append `script` element to `document.body`
var content = document.createElement("div");
content.innerHTML = xmlhttp.responseText
var div = content.querySelector("#htmlContent");
var contentScript = content.querySelector("#contentScript");
var script = document.createElement("script");
script.textContent = contentScript.textContent;

I'm using QUnit for unit testing js and jquery.
My HTML looks like this:
<!DOCTYPE html>
<html>
<head>
<title>QUnit Test Suite</title>
<script src="../lib/jquery.js"></script>
<link rel="stylesheet" href="http://code.jquery.com/qunit/qunit-1.16.0.css" type="text/css" media="screen">
<script type="text/javascript" src="http://code.jquery.com/qunit/qunit-1.16.0.js"></script>
<!--This is where I may have to add startPage.html--->
<script src="../login.js"></script>
<script src="../test/myTests.js"></script>
</head>
<body>
<div id="qunit"></div>
<div id="qunit-fixture"></div>
</body>
</html>
Currently, I'm adding login.js as shown and I'm getting references correctly to objects defined in login.js.
However, functions in login.js contains references to some dom elements defined in startPage.html which is located elsewhere.
So, if I say $('#login-btn'), it is throwing an error. Is there any way to fix this?
Can I
(a) refer to startPage.html to my qunit page given above?
(b) refer to or load startPage.html in the file where I'm running tests (myTests.js):
QUnit.test( "a test", function( assert ) {
assert.equal( 1, "1", "String '1' and number 1 have the same value" );//works
assert.equal( login.abc, "abc", "Abc" );//works with attributes
assert.equal(($("#userid").val()),'', 'Userid field is present');//fails
assert.equal( login.ValidUserId(), true, "ValidUserId" );//fails with functions
});
Does QUnit provide any method to load Html/php files so they'll be defined prior to testing. Like 'fixtures' in jasmine?
EDIT: Please also tell what to do in case I have startPage.php
There are a couple of ways you can do this. The simplest is just to use the built-in QUnit "fixtures" element. In your QUnit HTML file, simply add any HTML you want in the div with the id of qunit-fixture. Any HTML you put in there will be reset to what it was on load before each test (automatically).
<html>
...
<body>
<div id='qunit'></div>
<div id='qunit-fixture'>
<!-- everything in here is reset before each test -->
<form>
<input id='userid' type='text'>
<input id='login-btn' type='submit'>
</form>
</div>
</body>
</html>
Note that the HTML in the fixture doesn't really have to match what you have in production, but obviously you can do that. Really, you should just be adding the minimal necessary HTML so that you can minimize any side effects on your tests.
The second option is to actually pull in the HTML from that login page and delay the start of the QUnit tests until the HTML loading is complete:
<html>
<head>
...
<script type="text/javascript" src="http://code.jquery.com/qunit/qunit-1.16.0.js"></script>
<script>
// tell QUnit you're not ready to start right away...
QUnit.config.autostart = false;
$.ajax({
url: '/path/to/startPage.html',
dataType: 'html',
success: function(html) {
// find specific elements you want...
var elem = $(html).find(...);
$('#qunit-fixture').append(elem);
QUnit.start(); // ...tell QUnit you're ready to go
}
});
</script>
...
</head>
...
</html>
Another way to do this without using jquery is as follows
QUnit.config.autostart = false;
window.onload = function() {

i have the index.html page.
Inside that page i have javascript code that makes a button to evoke ajax request for the other.html to be shown inside a div in index.html .
The other.html have nothing else but a div ( that contains the content ) and some javascript code.
The other.html loads normally inside the index.html but the javascript code does not work.
Anyone know why is this happening?
Thank you.
( the javascript code is as simple as an alert("hello") message ).
code:
index.html:
<html>
<head>
<script src=main.js></script>
</head>
<body>
<div id="to_change">bla bla bla</div>
<div id="button">click me</div>
</body>
<html>
main.js:
...
...
function sendRequest()
{
request.open("GET","other.html",true);
request.onreadystatechange = function(){
if(request.readyState == 4 && request.status == 200){
var response = request.responseText;
if(response) {
document.getElementById("to_change").innerHTML = response;
}
}
}
request.send(null);
}
....button.click(...sendRequest...);
...
...
other.html
<script type=...>alert("hello");</script>
<div>text text text text</div>
javascript is loading but function call is not happening.
You are not calling the functions in any event.
<BODY onLoad="alert('hello world!')">
Like this try to call the function . On any event you want
Make sure to remove the enclosing '<doctype...>', '<html>', and '<body>' tags from the "other.html" file, in case they are present.
You could try running the scripts manually:
// ...
if (response) {
var toChange=document.getElementById("to_change"), scripts, i;
toChange.innerHTML = response;
scripts = toChange.getElementsByTagName('script');
for (i=0; i<scripts.length; i++) {
eval(scripts[i].innerHTML);
}
}
Of course, eval is evil, so use at your own risk...
