Multiple execute js script - javascript

I have a problem with js script.
I load subpage by ajax and append code to div.
$.ajax ({
type: "POST",
url: "load/page/",
dataType: "json",
success : function(data) {
$('.content').empty();
$('.content').append(data);
},
error : function(e) {
console.log(e);
}
});
Subpage contains appeal to js script:
<script src="//<?php echo $_SERVER['SERVER_NAME'].'/'.BASE_DIR; ?>/scripts/settings.js"></script>
Why when i execute ajax multiple times settings.js events are executing multiple too? I want to could execute ajax code multiple times but js scripts are executing only once.

I replaced $(document) to $('.content') and add line $('.content').off(), now code is working great.

I want to know how to send ajax request in embeded javascript of pug file
To me there seems to be two issues
You have put unnecessary tabs in your function under (function (){
You need to use document.ready to ensure that HTML content is
ready. You can avoid this if you don't really care for DOM once you have the response
check a working example below
doctype html
html
head
script(src='https://ajax.googleapis.com/ajax/libs/jquery/3.1.1/jquery.min.js')
script.
$(document).ready(function(){
$.ajax({url: "demo_test.txt", success: function(result){
$("#div1").html(result);
}});
});
body
#div1
h2 Let jQuery AJAX Change This Text
Here there is no problem with your pug template (maybe just you can remove ()after #payment-form() because it is empty and it's not a mixin). But with your JS, you send the AJAX request immediatly, you should bind it to an event (click on a button, keypress on an input, etc.). Then you have to be sure you put your lib jquery.js in a directory you can access from your browser with scripts/jquery.js. If it's still not work after this change please report more precisely your error (open the console to get the messages, get us the behavior you expect and the behavior you get).

Ajax Not Loading PHP

I'm trying to load a PHP file into another PHP file on a click event through Ajax. I'm trying to do this to eliminate loading several modals I have on the page. It seems the PHP file is loading (in the console), but nothing is showing up.
Here's my javascript:
$("a#lightbox-open").click(function(e){
e.preventDefault();
$("body").addClass("noscroll");
$('section#lightbox').addClass("open");
$.ajax({
context: '#lightbox-holder',
url: '/template/lightbox.inc.php',
type: 'POST',
dataType: "json",
success: function(html){
alert("works");
}
});
});
In my main PHP file, I have a div #lightbox-holder that lightbox.inc.php is supposed to load into it.
context expects a (Plain)Object (as you can read in the api doc). Replacing '#lightbox-holder' by $('#lightbox-holder') will do the trick.
Working fiddle with the $() added versus non working fiddle representing your current code.

how to run javascript code that included through ajax process

I have a php page which has lot's of code of html and javascript inside it.Ihe other page use ajax to send an id to the first page and get the results and put it inside a div element. Now I want to run those returned codes which contains javascript and html codes.
How should that be done?
This is my ajax request to the first page:
$(document).ready(function() {
$.ajax({
type: "POST",
url: "showing.php",
data: "s_id="+s_id+"&submit=true",
success: function(msg){
str=$.trim(msg)
document.getElementById('tabs-2').innerHTML = str;
document.getElementById("ui-id-2").click();
}
})
I think event delegation can solve your problem.
Like below:
Use $.on(). Instead of registering events on the element you register on a parent which will not be removed
Ex:
$('#tabs-2').on('click', '#ui-id-2', function(){
//do something
})

How to open an html page in and html div?

The question might be a little misleading as I don't want to know how to open a html document in a div ,but I asked the question as I am currently facing a problem where I can't replace the html file which I have already placed in a div
I have already placed a html file in a div using ajax like this:
$.ajax({
url: 'calender.aspx',//this is html.aspx file
cache: false,
dataType: "html",
success: function (data) {
$(".mainBar").html(data);//mainBar is the div
}
});
this file gets placed on page load i.e document.ready function ,till here everything is fine.....my trouble starts when I want to replace the file,what I do is call a javascript function say replaceFile() on button click and write the same code to replace the file (changing the url of course)
like this
function replaceFile()
{
$.ajax({
url: 'Another.aspx',
cache: false,
dataType: "html",
success: function (data) {
$(".mainBar").html(data);
}
});
}
but this doesn't work,please help me out!
I guess your binding is not working when you try to click on the content you loaded via ajax . So you might want to change the binding of onclick from
$("#someButtonId").click(function(){
replaceFile();
});
to
$(document).on("click","#someButtonId",function(){
replaceFile();
});
jQuery on works with current and future elements.
with this function you will load the page into the element named result
.load( url , data, complete(responseText, textStatus, XMLHttpRequest)] )
function replaceFile(url)
{
$('#result').load(url, function() {
alert('Load was performed.');
});
}
replaceFile('htmlfile.html');
You can load this in Firebug and set a break point at $(".mainBar").html(data); to make sure it's being called. You don't have a failure handler, so it's possible that it's actually receiving an HTTP failure code, not a success code.
I'd also look at the network traffic under the Net tab to see what the request/response looks like. That's an easy way to find out what is really going on with most AJAX calls. IE9 has similar developer tools if you want to use it and not Firefox or Chrome.

Load javascripts inside jQuery Ajax

I have several javascripts at the head of my document, as well as at the bottom, near the body closing tag. I use jQuery to call an ajax element into place and the elements that are called, require these javascripts to function. How can I include these javascripts to work with the ajax call?
Example:
jQuery(document).ready(function(){
jQuery("a[rel=VideoPreview1]").click(function(){
jQuery("a[rel=VideoPreview1]").hide();
jQuery("a[rel=HideVideoPreview1]").show();
jQuery.ajax({
type: "POST",
url: "/Classes/Video.php",
data: "action=getYoutubeVideos&artist=B.o.B&track=Nothin On You",
success: function(data){
jQuery("#VideoPreview1").html(data);
}
});
jQuery("#VideoPreview1").show();
preventDefault();
});
jQuery("a[rel=HideVideoPreview1]").click(function(){
jQuery("a[rel=VideoPreview1]").show();
jQuery("a[rel=HideVideoPreview1]").hide();
jQuery("#VideoPreview1").hide();
preventDefault();
});
});
So that ajax function loads the content inside of the proper DIV element. The head contains the core files (i.e. jquery, tooltip, lightbox) and near the bottom of the code, the javascripts are referenced (i.e. load.tooltip(VideoPreview1))
Hope this is enough information now
Ok here is what I ended up doing:
<script>
function BottomVideoPlayer(){
// MY JAVASCRIPT HERE
}
jQuery(document).ready(function(){
init: BottomVideoPlayer();
});
</script>
And then when I want to call it into Ajax:
<script>
jQuery.ajax({
type: "POST",
url: "/Classes/Video.php",
data: "action=getYoutubeVideos&artist='.$Artist.'&track='.$Track.'",
success: function(data){
jQuery("#VideoPreview'.$SongID.'").html(data);
init: BottomVideoPlayer();
}
});
</script>
Just wrapped my script around a function and initiate the function whenever I need it.
