Ajax call url in an external js file

I have a web page (written in php / codeigniter) that uses some javascript code.
I tried to move some javascript code to external file to better manage the code.
So in document ready event I load external file with
$.getScript('<?php echo base_url();?>assets/js/offerta_editScontirow.js');
one piece of code, putted in an external js file, does not work; instead it works correctly if I put all the code inside the main php file.
$.ajax({
dataType: 'json',
url: '<?php echo site_url("Offerta/applica_sconti");?>',
cache: false,
data: data,
success: function (data, status, xhr)
{
........
It does not work because it does not elaborate the php code, and in the query string I find
"php echo site_url("Offerta/applica_sconti");?>:"
So, is there a way to have it works? May I pass any parameter to the external js file while loading it, and pass the url to be used in ajax call? Some other method?
Kind regards,
Matt

try this window.my_url = 'some value'; and get the variable like below
window.my_url = '<?php echo site_url("Offerta/applica_sconti");?>';
$.getScript('<?php echo base_url();?>assets/js/offerta_editScontirow.js');
and
$.ajax({
dataType: 'json',
url: my_url,
cache: false,
data: data,
success: function (data, status, xhr)
{

Open file upload dialog after Ajax post success

I have functionality in which it is required to open file upload dialog after Ajax call success event.
What I tried:
I tried applying below simple code in ajax success: and complete: event but it is not working.
$.ajax({
url: url,
type: 'GET',
dataType: 'json',
data: { id: eoid },
contentType: 'application/json; charset=utf-8',
success: function (data) {
// some logic
$("#fileupload").click();
}
});
What is problem:
If I put simple button and try to execute above code, it is working fine and opening dialog - but it is not working in case of ajax post afterwards.
Any guesses or am I missing something?
Thank you.

The problem is at dataType: 'json' . You are loading html with your ajax request so you should change it to dataType: 'html' else in any other format it will not be considered success. Or you can delete this property as stated in Jquery doc that Jquery does default: Intelligent Guess (xml, json, script, or html).

Ajax request inside ajax request with Laravel

I have a code that works like this:
$.ajax({
type: "POST",
url: url,
data: formData,
cache: false,
processData: false,
contentType: false,
dataType: 'html',
This loads:
Route::post('/local/pdf', 'LocalController#subirPDF');
Which loads the controller:
return View::make(Config::get('rv.paginasPDF'));
Which loads:
$.get("{{Request::root()}}/local/actualizar_paginas/9/2");
Which loads the route:
Route::get('/local/actualizar_paginas/{id}/{paginas}', 'LocalController#actualizarPaginas')->where('id', '[0-9]+')->where('paginas', '[0-9]+');
That loads:
Auth::user()->perfil='penadaaaaaafe';
Auth::user()->save();
Don't worry if you see that I don't use some variables, because I have simplified the code to make it easier to explain.
Basically, if I load directly the route from the url everything works fine:
{{Request::root()}}/local/actualizar_paginas/9/2"
But if I load it with the ajax method that I have devoloped it doesn't work. If I console.log the data I recieve the right html code of the $.get page, but It doesn't make the get request.
Any idea how to fix it?
Thanks.

redirect with javascript to another domain with Json

I'm retrieving an url from a php file with Json , and then in the success part I do
window.location=msg.message
but the proble is that if we suppose my domain is http example.com and the
msg.message value is
https://otherdomain.com
the redirection is done to http:/example.com/https:/otherdomain.com
how can I go directly to https:/otherdomain.com
code
$.ajax({
type: "POST",
url: "ajax.php",
data: dataString,
dataType: "json",
success: function (msg){
$.fn.colorbox.close();//close the box
alert(decodeURI(msg.message));//
window.location.href(msg.message); // goes to domain.com/msg.message
},
});

Please use assign method:
window.location.assign("https://otherdomain.com")

You need two stashes before the host part of the URL.
https://otherdomain.com
You have only one (https:/otherdomain.com).
(And href is a string, not a function, assign a value to it as you do in the first code block, don't try to call it as you do in the third).

Can I bind asp.net dropdownlist using javascript/jquery?

Can I bind asp.net dropdownlist using javascript/jquery? I get the data from jquery ajax from a web method so I want to avoid postback at this point. But I still want to do postback and save all the data using server side code (i.e. I still be able to do this dropdownlist1.selecteditem.text) after binding it using clientscripts.
Is it possible and can someone explain me how it can be done?
Thanks,

Use Json ajax
Syntax:
$.ajax({
dataType: "json",
url: url,
data: data,
success: success
});
See simple example for json:
<script type="text/javascript">
$(document).ready(function () {
var msgbox = $("#status");
$("#Button1").click(function () {
$.ajax({
type: "POST",
//Page Name (in which the method should be called) and method name
url: "BeginJson.aspx/CheckDateTime",
// If you want to pass parameter or data to server side function you can try line
// data: "{}",
//else If you don't want to pass any value to server side function leave the data to blank line below
data: "{'args':'Somnath'}",
contentType: "application/json; charset=utf-8",
dataType: "json",
success: function (msg) {
//Got the response from server and render to the client
msgbox.html(msg.d);
}
});
});
});
