I have an external end point
localhost:5000 which loads a simple html page with an image. A flask server is running there which serves html content.
I have another html file called index.html . In the index.html, I have a div called movie-data . I want to make a Ajax request localhost:5000 and append the html content in the div movie-data of index.html .
index.html :-
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<script>
function init() {
$.ajax({
dataType: "html",
url: "http://localhost:5000",
success: function (data) {
console.log(data);
$("#movie-data").html($(data).append(data));
}
});
init();
</script>
<div id="movie-data"></div>
It is showing error,
Uncaught SyntaxError: Unexpected end of input
init();
no closing tag of function was found
fix : -
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<script>
function init() {
$.ajax({
dataType: "html",
url: "http://localhost:5000",
success: function (data) {
console.log(data);
$("#movie-data").append(data);
}
});
}
init();
</script>
<div id="movie-data"></div>

I'm using an ajax call to append a MVC partial view with some styles sheets and script files to my php page.
However it is not appending de <script> tags. I already checked my HTTP request on the network and it really brings those tags.
My code:
$.ajax({
type: 'POST',
url: 'http://localhost:63322/MyController/MyAction', //external url project
data: JSON.stringify(parameters),
contentType: 'application/json; charset=utf-8',
dataType: 'json',
async: true,
crossDomain: true,
processdata: true,
headers: {
"Access-Control-Allow-Origin" : "*",
"Access-Control-Allow-Headers": "*"
},
success: function(result){
$(".pageContainer").html(result);
},
error: function(er){ alert('Error'); }
});
On ajax success function I already tried:
to use $(".pageContainer").empty().append(result)
to separate the script tags and add to <head> like this:
var elems = $(result);
var scripts = $.grep(elems, function(e){
try{
return e.tagName.toLowerCase() == "script";
}catch(er){ return false; }
});
var remainElems = $.grep(elems, function(e){
try{
return e.tagName.toLowerCase() != "script";
}catch(er){ return false; }
});
$.each(scripts, function(){ $('head')[0].appendChild(this); });
$(".pageContainer").append(remainElems);
to give some time before appending with setTimeout(function(){ $(".pageContainer").html(result); }, 1000);
to change <script> tags to <link type="text/javascript" src="http://someurl.com" rel="tag"/> and it was appended but the code wasn't executed
But nothing works.
What is wrong? What I'm missing?
My PHP page uses jquery-1.8.3 and jquery-ui-1.9.2.custom. This is the problem?
NOTE:
My question is very different from that on: Executing inside retrieved by AJAX
If you read both you will see they are very different. I already readed what and noticed that.
Solved. I don't know why but seems jquery-1.8.3 don't performs the insertion of the <script> tags to the html code dynamically.
I changed
<script type="text/javascript" src="js/jquery-1.8.3.js"></script>
to
<script type="text/javascript" src="js/jquery-1.10.2.js"></script>
and now it works.
I have two .cshtml webforms, in one webform I have Bootstrap header and in other webform I have one div containg form. Now I want to implement such thing like when I click any of links available in Header that time Jquery function will be called and it should get desired page and load it into defined div block.
My code is seems as bellow (header.cshtml) :
<html>
<head>
<script type="text/javascript" src="../assest/js/jquery-3.1.1.js"></script>
<script type="text/javascript">
function myFunction(str) {
$(document).ready(function () {
//alert(str);
$.ajax({
type: "GET",
url: str + ".cshtml",
dataType: "html",
success: function (data) {
$("#form_load").html(data);
},
error: function (data) {
alert(data);
}
})
});
}
</script>
</head>
<body>
<div>
<a id="nav_link" onclick="myFunction(this.name)" name="farmer_master">Farmer</a>
</div>
<div id="form_load"></div>
</body>
</html>
other webform (farmer_master.cshtml) :
<div>
Hi I shoud be called !
</div>
I'm using an Ajax for partial loading my website. Content of GET data has images but these images appear after few seconds on page. Image size is about 20kB, so this is not a bottleneck.
I'm using php page which returns some content. This page loads in a while with images immediately but with ajax it loads text, but images after few seconds. How can I achieve quick load?
I'm using this function:
function loadMainEvents(resultDiv, cat, limit){
var spinner = new Spinner().spin(mainPageEvents);
$.ajax({
url: "/getMainPageEvents.php?category=" + cat + "&limit=" + limit,
type: "GET",
success: function(data){
resultDiv.innerHTML = data;
spinner.stop();
}
});
};
EDIT:
I created a test.php which is doing same thing
<html>
<head>
<script src='https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js' type="text/javascript"></script>
</head>
<body>
<div id="div" style="float:left;">wait</div>
<div id="div2">wait</div>
<script>
$(function () {
$.ajax({
url: "/getMainPageEvents.php?category=&limit=10&from=29.11.2015&to=29.11.2015&pno=1",
type: "GET",
success: function (data) {
$("#div").html(data).on('load', function () {
$(this).fadeIn(250);
});
}
});
$.ajax({
url: "/getMainPageEvents.php?category=&limit=10&from=29.11.2015&to=29.11.2015&pno=1",
type: "GET",
success: function (data) {
$("#div2").html(data).on('load', function () {
$(this).fadeIn(250);
});
}
});
});
</script>
</body>
getMainPageEvents.php returns only web content.
Network from developer tools:
You may want to try something like this in the success function. Hide the result div first and foremost, then after the data is loaded, show the div.
$(resultDiv).html(data).promise().done(function(){
spinner.stop();
$(this).fadeIn(250);
});
Possible second solution
$(resultDiv).html(data).on('load', function(){
spinner.stop();
$(this).fadeIn(250);
});
So I have a page which, when requested, updates my database. For example when I go to database_update.php it just updates the database and doesn't show anything.
Index.php shows user database content.
So I have function in JavaScript called update which must use AJAX to run this page and after the page loads (after all queries run successfully) it must load index.php and show updated page to the user (reload the page without refresh effect).
My code is like:
$.get('ajax_update_table.php', {
// The following is important because page saves to another table
// users nick which call update:
update: UserLogin
}, function (output) {
// The following is unimportant:
$(myDiv).html(output).show();
});
Two suggestions:
Return a "success" or "error" code from your database_update script. Returning a JSON string is very easy. For example:
echo '{"success":"success"}';
Use the $.ajax function. Then add the success, error, and complete parameters. You can call any javascript function(s) when the AJAX request is complete.
$.ajax({
url: 'update_database.php',
dataType: 'json',
success: function (data) {successFunction(data)},
error: function () { error(); },
complete: function () { complete(); }
});
function successFunction(data) {
if ('success' in data) {
// Do success stuff here.
} else {
// Show errors here
}
}
// .... etc
I might be missing something, but I'll try to answer your question.
I would setup a blank page that on loading it sends the index.php to a div on that page. For example, make a page titled blank.php.
blank.php would have the following:
function Index(){
$.ajax({
url:"index.php",
type: "GET",
success:function(result){
$("#web-content").html(result);
}
});
}
<script type="text/javascript">Index();</script>
<div id="web-content"></div>
You would then have your index execute the Index function to update the web-content div with the index.php data without reloading the blank.php page.
Got it to work!
my index.php
<html>
<head>
<script type="text/javascript" language="Javascript" SRC="http://code.jquery.com/jquery-1.8.2.min.js"></script>
<script type="text/javascript" language="Javascript">
function update_and_replace()
{
$.ajax({
url: 'ajax_update_table.php',
dataType: 'json',
success: function (data) {successFunction(data)},
error: function () { error(); },
complete: function () { complete(); }
});
}
function successFunction(data) {
if ('success' in data) {
$("#content").load("index.php");
}
}
</script>
</head>
<body>
<div id='content'>
Now is: <?php echo date("Y-m-d, H:i:s");?>
<br/><br/><br/><br/>
Aktualizuj
</div>
</body>
</html>
Ajax_update_table.php
<?php echo '{"success":"success"}'; ?>
Thank You all for your help.
I know that my English is bad but with your help I made it!
I am having some trouble calling a javascript function inside of the html page. When I move the function inside the linked/external file it works fine. Can anyone help with this?
Here is my external file.js
function request_token(session) {
$.ajax({
url: api_url,
data: {api_id: api_id},
dataType: "jsonp",
jsonp : "callback",
success: function(data) {
var token = data.token;
alert(token)
}
});
};
And here is just the simple call to the function that I want to load once the document is ready...
<script>
$(document).ready(function() {
request_token('1234');
});
</script>
When I move request_token('1234'); into the file external file, it works fine
use jQuery's getScript() function.
<script>
$(document).ready(function() {
$.getScript('external.js');
request_token('1234');
});
</script>
