Passing parameters between html pages using jquery

I have one html page which contains a jquery function.
<script>
function loadCustomers() {
$.ajax({
type: 'GET',
url: 'http://localhost:8080/cache/getCustomers',
dataType: 'json',
success: function(data) {
var rows = [];
$.each(data,function(id,value) {
rows.push('<tr><td><a href="clientSiteInfo.html?client=">'+id+'</td><td>'+value+'</td></tr>');
});
$('table').append(rows.join(''));
}
});
};
window.onload = loadCustomers;
</script>
I have linked another html page for each row. When each rows populated, the id values has to be passed to the clientSiteInfo.html page.
In the clientSiteInfo.html page i have another jquery function similar to above.
<script>
function loadSites() {
$.ajax({
type: 'GET',
url: 'http://localhost:8080/cache/getSite?clientName='+${param.client},
dataType: 'json',
success: function(data) {
var rows = [];
$.each(data,function(id,value) {
rows.push('<tr><td>'+id+'</td><td>'+value.machine+'</td><td>'+value.state+'</td></tr>');
});
$('table').append(rows.join(''));
}
});
};
window.onload = loadSites;
</script>
in the GET url I try to read client parameter. But it is not passing from my initial page.
What Im doing wrong here? I look for simple solution

jQuery doesn't have a native way to read the url parameters. However, javascript works just fine:
function getParameterByName(name) {
const match = RegExp(`[?&]${name}=([^&]*)`).exec(window.location.search);
return match && decodeURIComponent(match[1].replace(/\+/g, ' ') );
}
In your code you would just call it as getParameterByName('client')

(this).parent().find not working for getting response in ajax call

$(".content-short").click(function() {
$(".content-full").empty();
var contentid=$(this).parent().find(".content-full").attr('data-id');
var content=$(this).parent().find(".content-full");
alert(contentid);
var collegename = $(this).attr('data-id');
$.ajax({
type: "post",
url: "contenthome.php",
data: 'collegename=' + collegename,
dataType: "text",
success: function(response) {
$content.html(response);
}
});
});
here the alert displays the specific data-id but
content=$(this).parent().find(".content-full");
this didn't displays data in content-full div with that specific data-id
anything wrong in the code or something else?
the query displays data if i use(."content-full"); instead of
$(this).parent().find(".content-full");

Inside the ajax callback you are using $content, but you declare your variable as content. May that be the problem?
Your question is not clear. What are you trying to achieve?

show exact result for each div after success AJAX callback

I am struggling trying to get the corresponding result for each item after successful AJAX callback. I am able to get the results, but not individually in each div from the item when there is more than one, each item displayed is getting all the results in the div and not just the corresponding one.
var xhr = $.ajax({
type: "HEAD",
url: image,
success: function(){
$(".block .image-sze").append(xhr.getResponseHeader('Content-Length'));
}
});
Can someone help me to fix the above so it can show individual result for each item?

The selector $(".block .image-sze") is only selecting the first class with block, use $("*.block *.image-sze") instead!
The "*" selects all tag that has the same class!
Hope this help?

maybe you're looking for something like this?
var xhr = $.ajax({
type: 'POST',
dataType: 'json'
url: url,
success: function(json){
$('#image1').html(json['image1']);
$('#image2').html(json['image2']);
}
});
And you're calling from url with something like this
public function somefunction() {
$json = array();
$json['image1'] = 'image1';
$json['image2'] = 'image2';
echo json_encode($json);
}

Reading a file into a string in jQuery/JS

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.

Unable to hide a imag using .hide()

I have the following view inside my asp.net mvc , which display a ajax-loading imag, which i am trying to hide after starting a jquery function as follow:-
<div id= "geturl" data-url="#Url.Action("ListPackages", "Home")">
<h1>All Processes</h1>
<img id="tobehide" src="~/Content/ajax-loading2.gif" />
<ul id="products">
</ul>
Then the following JavaScript file:-
$(document).ready(function () {
$.ajax({
url: $('#geturl').data('url'),
type: 'GET',
cache: false,
success: function (result) {
$('#tobehide').hide();
$.each(result.data, function (key, val) {
var str = val.packageName;
$('<li/>', { text: str })
.appendTo($('#products'));
});
}
});
});
Currently the data will be filled in the but the loading-imag will not be hiden.so how i can force the imag to hide when the java script starts executing?.
Best Regards

Your code is correct, and should work fine!
Try using FireBug or Chrome developer tools to see what's the javascript error you are getting back from the ajax call.
If that still doesn't help, and you want the image to be hidden regardless, then use the 'complete' callback on the jquery ajax call you are using.
$(document).ready(function () {
$.ajax({
url: $('#geturl').data('url'),
type: 'GET',
cache: false,
complete: function (result) {
$('#tobehide').hide();
$.each(result.data, function (key, val) {
var str = val.packageName;
$('<li/>', { text: str })
.appendTo($('#products'));
});
}
});
});

It should work fine. No mistake in your code Brother.
try adding async option. Set it to false. and try again
