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

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() {
$("#navigation").load("navbar.html");
});
in a separate file and then load javascript file on html page
showhide.html
<!DOCTYPE html>
<html>
<head>
<script type="text/javascript">
function showHide(switchTextDiv, showHideDiv)
{
var std = document.getElementById(switchTextDiv);
var shd = document.getElementById(showHideDiv);
if (shd.style.display == "block")
{
shd.style.display = "none";
std.innerHTML = "<span style=\"display: block; background-color: yellow\">Show</span>";
}
else
{
if (shd.innerHTML.length <= 0)
{
shd.innerHTML = "<object width=\"100%\" height=\"100%\" type=\"text/html\" data=\"showhide_embedded.html\"></object>";
}
shd.style.display = "block";
std.innerHTML = "<span style=\"display: block; background-color: yellow\">Hide</span>";
}
}
</script>
</head>
<body>
<a id="switchTextDiv1" href="javascript:showHide('switchTextDiv1', 'showHideDiv1')">
<span style="display: block; background-color: yellow">Show</span>
</a>
<div id="showHideDiv1" style="display: none; width: 100%; height: 300px"></div>
</body>
</html>
showhide_embedded.html
<!DOCTYPE html>
<html>
<head>
<script type="text/javascript">
function load()
{
var ts = document.getElementById("theString");
ts.scrollIntoView(true);
}
</script>
</head>
<body onload="load()">
<pre>
some text 1
some text 2
some text 3
some text 4
some text 5
<span id="theString" style="background-color: yellow">some text 6 highlight</span>
some text 7
some text 8
some text 9
</pre>
</body>
</html>
If your html file resides locally then go for iframe instead of the tag. tags do not work cross-browser, and are mostly used for Flash
For ex : <iframe src="home.html" width="100" height="100"/>
laravel Controller
if($validator->failed())
{
return redirect()->back()->with(['errors'=>$validator->errors(),'input'=>$request]);
}
JavaScript file
<script type="text/javascript" >
var registrationErrors = #json($errors);
var input= #json($input);
</script>
In this case registrationErrors it's working fine but input return error like
Action Facade\Ignition\Http\Controllers\ExecuteSolutionController not defined.
If pass only one argument in with() function that should be work fine.
Laravel Controller
if($validator->failed())
{
$data=["errors"=>$validator->errors(),
"input" => $input
];
return redirect()->back()->with('data',$data);
}
Java Script
<script type="text/javascript" >
var data = #json($data);
</script>
My issue is solved, this way is perfectly working
I know this has been asked a lot on here, but all the answers work only with jQuery and I need a solution without it.
So after I do something, my Servlet leads me to a JSP page. My JS function should populate a drop down list when the page is loaded. It only works properly when the page is refreshed tho.
As I understand this is happening because I want to populate, using innerHTML and the JS function gets called faster then my HTML page.
I also get this error in my Browser:
Uncaught TypeError: Cannot read property 'innerHTML' of null
at XMLHttpRequest.xmlHttpRequest.onreadystatechange
I had a soulution for debugging but I can't leave it in there. What I did was, every time I opened that page I automatically refreshed the whole page. But my browser asked me every time if I wanted to do this. So that is not a solution that's pretty to say the least.
Is there something I could do to prevent this?
Edit:
document.addEventListener("DOMContentLoaded", pupulateDropDown);
function pupulateDropDown() {
var servletURL = "./KategorienHolen"
let xmlHttpRequest = new XMLHttpRequest();
xmlHttpRequest.onreadystatechange = function () {
if (xmlHttpRequest.readyState === 4 && xmlHttpRequest.status === 200) {
console.log(xmlHttpRequest.responseText);
let katGetter = JSON.parse(xmlHttpRequest.responseText);
JSON.stringify(katGetter);
var i;
for(i = 0; i <= katGetter.length -1; i++){
console.log(katGetter[i].id);
console.log(katGetter[i].kategorie);
console.log(katGetter[i].oberkategorie);
if (katGetter[i].oberkategorie === "B") {
document.getElementById("BKat").innerHTML += "" + katGetter[i].kategorie + "</br>";
} else if (katGetter[i].oberkategorie === "S") {
document.getElementById("SKat").innerHTML += "" + katGetter[i].kategorie + "</br>";
} else if (katGetter[i].oberkategorie ==="A") {
document.getElementById("ACat").innerHTML += "" + katGetter[i].kategorie + "</br>";
}
// document.getElementsByClassName("innerDiv").innerHTML = "" + katGetter.kategorie + "";
// document.getElementById("test123").innerHTML = "" + katGetter.kategorie + "";
}
}
};
xmlHttpRequest.open("GET", servletURL, true);
xmlHttpRequest.send();
}
It can depend on how + when you're executing the code.
<html>
<head>
<title>In Head Not Working</title>
<!-- WILL NOT WORK -->
<!--<script>
const p = document.querySelector('p');
p.innerHTML = 'Replaced!';
</script>-->
</head>
<body>
<p>Replace This</p>
<!-- Will work because the page has finished loading and this is the last thing to load on the page so it can find other elements -->
<script>
const p = document.querySelector('p');
p.innerHTML = 'Replaced!';
</script>
</body>
</html>
Additionally you could add an Event handler so when the window is fully loaded, you can then find the DOM element.
<html>
<head>
<title>In Head Working</title>
<script>
window.addEventListener('load', function () {
const p = document.querySelector('p');
p.innerHTML = 'Replaced!';
});
</script>
</head>
<body>
<p>Replace This</p>
</body>
</html>
Define your function and add an onload event to body:
<body onload="pupulateDropDown()">
<!-- ... -->
</body>
Script needs to be loaded again, I tried many options but <iframe/> works better in my case. You may try to npm import for library related to your script or you can use the following code.
<iframe
srcDoc={`
<!doctype html>
<html>
<head>
<style>[Style (If you want to)]</style>
</head>
<body>
<div>
[Your data]
<script type="text/javascript" src="[Script source]"></script>
</div>
</body>
</html>
`}
/>
Inside srcDoc, it's similar to normal HTML code.
You can load data by using ${[Your Data]} inside srcDoc.
It should work :
document.addEventListener("DOMContentLoaded", function(){
//....
});
You should be using the DOMContentLoaded event to run your code only when the document has been completely loaded and all elements have been parsed.
window.addEventListener("DOMContentLoaded", function(){
//your code here
});
Alternatively, place your script tag right before the ending body tag.
<body>
<!--body content...-->
<script>
//your code here
</script>
</body>
So I'm trying to start on a to do list in html5 + jQuery using Local Storage, but for some odd reason I can't get the jQuery to make a local storage key.
Here is my code. I want it to collect the value of the input box, add it to local storage, and then print the code in the div named.
$('#taskEntryForm').submit(function () {
if ($('#taskInput').val() !== '') {
var input_value = $('#taskInput').val();
var stored_input = this.localStorage.setItem('task_',input_value);
var task = this.localStorage.getItem('task_');
$('#taskList').append("<br>"+task);
};
return false;
});
and then the HTML...
<html>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.3/jquery.min.js"></script>
<script src="shit.js"></script>
</head>
<div id="cNew">
<form id="taskEntryForm">
<input id="taskInput" name="taskInput" autofocus></form>
</div>
<div id="taskList"></div>
</html>
In your code this stands for form. Local storage object is not part of the form, it is a part of window. You should change this (which represents form) to window, or remove this at all (because window.localStorage is identical to just localStorage):
$('#taskEntryForm').submit(function () {
if ($('#taskInput').val() !== '') {
var input_value = $('#taskInput').val();
var stored_input = localStorage.setItem('task_',input_value); // <- removed 'this'
var task = localStorage.getItem('task_'); // <- removed 'this'
$('#taskList').append("<br>"+task);
};
return false;
});
Here is a working jsFiddle
So, I've found this JSFiddle example. In JSFiddle works well, the problem is that, even if I search any != from "advogados" (just testing), the browser goes to: http://www.site.com/index.html?procura=teste
No jQuery conflict, no html issue.
Here's JS
$("#procura").on("submit", function(event){
// prevent form from being truely submitted
event.preventDefault();
// get value of text box
name = $("#procura_texto").val();
// compare lower case, as you don't know what they will enter into the field.
if (name.toLowerCase() == "advogados")
{
//redirect the user..
window.location.href = "http://jornalexemplo.com.br/lista%20online/advogados.html";
}
else
{
alert("no redirect..(entered: " + name + ")");
}
});
If your javascript is somewhere in your HTML before your <form> your $("#procura") will be an empty set, so the submit-action won't be bound to anything. Try following code:
<html>
<head>
<script type="text/javascript" src="/path/to/your/jquery.js"></script>
<script type="text/javascript">
$(function() {
// This code will be run if your document is completely
// parsed by the browser, thus all below elements are
// accessible
$('#procura').on('submit', ....);
});
</script>
</head>
<body>
<form id="procura">...</form>
</body>
</html>
$(function() {}) is also known as $(document).ready(function() {}), (documentation)
You aren't defining the variable name. http://jsfiddle.net/zwbRa/59/
var name = $("#procura_texto").val();
