I am using $.ajax to load the page content. In response I am getting whole html document as a string but I want to get the only particular div content from the response by using id of the div. I can't change the response and I can't use $.load method. Thanks in advance.
$.ajax({
url: ajax_url,
type: "GET",
dataType: "html"
}).done(function(data) {
}).fail(function(jqXHR, textStatus, errorThrown) {
});
In your .done() method:
.done(function(data) {
$('#target').html($(data).find('#specificDivId'))
})
As AJAX returns a plain text, you can transform it to jQuery DOM element, modify it and append (or replace HTML) to your HTML.
For example, this way:
$.ajax({
url: ajax_url,
type : "GET",
dataType : "html"
}).done(function(data) {
var obj = $(data);
$("#yourdiv").html(obj.find(".something").html());
}).fail(function(jqXHR, textStatus, errorThrown) {
});
I have used .find(".something") because I do not know the format of received message. You can use any jQuery methods.
What you want is basically what ajax shorthand method load() using page frament is doing:
$('#divToAddContent').load(ajax_url + ' #divToGetContent');
(note the space at starting fragment selector string)
You can use DOM parser.
$.ajax().success(function(data) {
var parser = new DOMParser();
var doc = parser.parseFromString(data, "application/xml");
// doc is a DOM now
});

What I want to do is pretty simple. I want to make an AJAX call to a specific html class, so that whenever the html page is loaded, jquery will make an AJAX call to that specific html div class.
For example:
<div class="targeted"></div>
In jquery:
$('.targeted')
I know that the syntax to make an AJAX call is:
$.ajax({
type: "GET",
url: "/api/something",
success: function(data) {
console.log(data);
}
});
But how do I implement this AJAX call to the $('.targeted') whenever the page is loaded?
Thanks
If you mean you want to display the result of the ajax call in the element, you update the element from within the success callback:
$.ajax({
type: "GET",
url: "/api/something",
success: function(data) {
$('.targeted').html(data);
}
});
That example assumes
You want to replace the content of the element (rather than adding to it); more options in the jQuery API.
data will be HTML. If it's plain text, use .text(data), not .html(data). If it's structured data, then of course you'll need to do more work to put the information in the desired form.
window.onload = function() {
yourFunction();
};
function yourFunction(){
$.ajax({
type: "GET",
url: "/api/something",
success: function(data) {
$('.targeted').html(data);
}
});
}
OR Drectly you can pass that method in document ready it will execute automatically
$(document).ready(function(){
//This will execute onload oof your web page what you required
yourFunction();
})
function yourFunction(){
$.ajax({
type: "GET",
url: "/api/something",
success: function(data) {
$('.targeted').html(data);
}
});
}
For when the page is loaded, you use:
$( document ).ready(function() {
console.log( "ready!" );
});
Inside the document ready, you put your AJAX call. If the result you get is in JSON format, you need to include the dataType as well like this:
$.ajax({
method: "GET",
url: "/api/something",
dataType: "json"
})
.done(function( data ) {
$('.targeted').append(JSON.stringify(data));
});
If the result is not JSON, then you can just append the data.
Also note:
The jqXHR.success(), jqXHR.error() and jqXHR.complete() callbacks are removed as of jQuery 3.0. You can use jqXHR.done(), jqXHR.fail() and jqXHR.always() instead.
Please look at the jQuery documentation.
you can use jquery load like this:
$(".targeted").load('/api/something');
if you want to wait untill after the page is loaded, wrap it with window load like so:
$(window).load(function () {
$(".targeted").load('/api/something');
});
P.S. $(window).load(..) and $(".class").load(url) are two different functions
You can do:
$(function() {
$.ajax({
type: "GET",
url: "/api/something",
})
.done(function(data) {
$('.targeted').text(data);
});
});
Alright, I have multiple buttons which call the same javascript function with a different ID.
Here's my function
function concur(id) {
//alert(id);
//throw ajax request
$.ajax({ //create an ajax request to load_page.php
type: "GET",
url: "ajax_getter.php?requestid=1&r=" + id,
dataType: "html", //expect html to be returned
success: function (response) {
$("#container").html(response);
//alert(response);
}
}); //ajax end
}
What would I do if I have to make the id as container name?
I mean, would this $("#id").html(response); work for all the dynamic changing ids within the function?
This didn't work for me. What would be the best solution ?
Use string concatenation to use a variable in the jQuery selector.
$("#" + id).html(response);
Everytime a page loads I need to load text into the CK Editor using JQuery, in order to get data from CK Editor I use
var editor_data = CKEDITOR.instances['editor1'].getData();
now is there a similar function I could use to put the data back into the editor?
I'm using ajax to set the data like this
$.ajax({
type: "POST",
url: "/inc/ajax/basic.php?menu_id="+menu_id+"&info=3",
success: function(msg){
CKEDITOR.instances['editor1'].setData(msg);
}
});
What am I doing wrong
Try this:
CKEDITOR.instances['editor1'].setData(html)
Where 'html' is a string containing content to edit.
Because its not an array then
just replace the instance like this
CKEDITOR.instances.editor1.setData(html)
var editor = CKEDITOR.instances.help_ldesc;
editor.setData('');
$.ajax({
url: urlstr, // Url to which the request is send
type: "POST", // Type of request to be send, called as method
data:{action:"ex_form"}, // Data sent to server, a set of key/value pairs (i.e. form fields and values)
contentType: false, // The content type used when sending data to the server.
cache:false, // To unable request pages to be cached
processData:false, // To send DOMDocument or non processed data file it is set to false
success: function(data) // A function to be called if request succeeds
{
//alert(data);
var data1=data.split("~`");
$('#help_id').val(data1[0]);
$('#help_title').val(data1[1]);
$('#help_sdesc').val(data1[2]);
editor.setData(''+data1[3]);
var edata = editor.getData();
alert(edata);
}
});
Use this code its works for me and (help_ldesc) is my textarea name.
you should use data, and method for sending query string like this:
$(document).ready(function()
{
var querystring="menu_id="+menu_id+"&info=3";
$.ajax({
method: "POST",
url: "/inc/ajax/basic.php",
data:querystring,
success: function(msg)
{
CKEDITOR.instances['editor1'].setData(msg);
}
});
});
var jqxhr = $.get( "file.php", function(data) {
CKEDITOR.instances.idOftextAreaName.setData( data );
alert( "success" );
})
.done(function() {
//alert( "second success" );
})
.fail(function() {
alert( "error" );
})
.always(function() {
// alert( "finished" );
});
CKEDITOR.instances['<%=ckEditor.ClientID%>'].setData(value);
From my experience using inside a function sometimes doesn't work properly. I'll suggest to use in:
$(document).ready(function () {
...
// instance, using default configuration.
CKEDITOR.replace('editor1');
//set data
CKEDITOR.instances['editor1'].setData(data);
...
});
The title is quite self-explanatory: I need to read a HTML file through jQuery and store its contents into a string variable.
I tried using .load and $.get, but they wouldn't do what I needed.
This is the code I've tried so far, based on the comments below, but they didn't populate my template variable at all:
var template = "";
$.ajax({
url: 'includes/twig/image_box.twig',
type: 'get',
success: function(html) {
var twig = String(html);
template.concat(twig);
}
});
console.log(template);
AND:
var template = "";
var fileUrl = "includes/twig/image_box.twig";
jQuery.get(fileUrl).then(function(text, status, xhr){
var html = String(text);
template.concat(html);
// console.log(html); // WORKS!
});
console.log(template); // Does not work
It's weird why this isn't working. Weird for me at least. This is how I'd populate a variable in PHP so I've carried the same logic to JS. Maybe there is an alternative way?
P.S:V I've also tried all alternative ways, like concatenating with += and assigning inside the callback function to template with =, but nothing worked.
Thanks to the ones who are trying to help me!
Maybe you should try a AJAX request with $.ajax()
Check the jQuery API here
$.ajax({
url: 'yourHTMLfile.html',
type: 'get',
async: false,
success: function(html) {
console.log(html); // here you'll store the html in a string if you want
}
});
DEMO
EDIT: Added a demo!
I reread your question and I noticed you're calling the console log right above the ajax request but you forgot the ajax is asynchronous that means the page will do a request and only will set the template value when the response return with success(if it returns). So the console.log(template) don't appears because it may be not loaded yet.
var template = "";
$.ajax({
url: 'includes/twig/image_box.twig',
type: 'get',
success: function(html) {
var twig = String(html);
template.concat(twig);
console.log(template); // the change!
}
});
or
$.ajax({
url: 'includes/twig/image_box.twig',
type: 'get',
async: false,
success: function(html) {
var twig = String(html);
template.concat(twig);
}
});
console.log(template); // the change!
You can try this:
//as you see I have used this very page's url to test and you should replace it
var fileUrl = "/questions/20400076/reading-a-file-into-a-string-in-jquery-js";
jQuery.get(fileUrl).then(function(text, status, xhr){
//text argument is what you want
});
and if it won't work try if your browser can open the file. if it could you'd better try ajax method in jQuery if not you might have some problems regarding permissions or somethings like that in you application server.
Is there any way to get the text inside an element which is a response from an ajax jquery load. I need to get the text inside element which is present inside the response text from ajax page. Following is my ajax code:
var url = '...';
var saveData = $.ajax({
type: 'POST',
url: url,
data: {data : data},
dataType: "text",
success: function (resultData) {
callback(resultData); // need to get the <h2> text here..
}
});
saveData.error(function () {
console.log("Request to API not send");
});
You can pass HTML to jQuery and use it in the same way as if the element was on the DOM, for example with find():
console.log( $(resultData).find('h2').text() );
If your HTML doesn't have a root element then you can wrap it like so:
resultData = '<div>' + resultData + '</div>';
console.log( $(resultData).find('h2').text() );
How about:
$(resultData).find('h2').text()
