一个ajax电话中的2个网址？

I was wondering if I can do this jquery ajax on my code:

$.ajax({
  type: "POST",
  dataType: 'json',
  url: "functions/ajaxNca_add.php", "functions/ajaxNca_update.php",
  data: dataString,
  cache: false,
  success: function(response){
    // show success
    alert(response.a);
}

The code above is just an example and I knew that it's not working. How can I call 2 php script in just one ajax request in jquery ? Can someone help ?

No you can not do this. If you will look at jquery ajax documentation, you will see that url accepts only string, not an array of stings.

You should either make two requests, or create another *.php entry point which will combine both php scripts and make a call to this one.

You can't call 2 url simultaneously.but you can call one after another.

        $.ajax({
      type: "POST",
      dataType: 'json',
      url: "functions/ajaxNca_add.php",
      data: dataString,
      cache: false,
      success: function(response){
$.ajax({
      type: "POST",
      dataType: 'json',
      url: "functions/ajaxNca_update.php",
      data: dataString,
      cache: false,
      success: function(response){
//responce
}

    });
}

    });

or

$.ajax({
          type: "POST",
          dataType: 'json',
          url: "functions/ajaxNca_add.php", 
          data: dataString,
          cache: false,
 async: true,
          success: function(response){
//responce
}});
 $.ajax({
          type: "POST",
          dataType: 'json',
          url: "functions/ajaxNca_update.php",
          data: dataString,
          cache: false,
 async: true,
          success: function(response){
//responce
}});

async: true - synchronizes your ajax calls

More simple way :

You can also do one ajax call to functions/ajaxNca_add.php file, and include second file functions/ajaxNca_update.php in first ajax file.

So from one ajax call, you can access 2 files at a time.

You can define the object first then you need to call ajax two times by changing the url.

var ajaxObj = {
    type: "POST",
    data: thisForm.serialize(),
    success: function (response) {
        if(response.status=="success"){
            dataLayer.push({'event' : 'requestdemo_form_submitted', 'request_demo_submit_event_gtm' : 'request_demo_submit_event_gtm'});
            $('.sidebar-req-sec').addClass('hide');
            $('.sidebar-req-sec-thnk').removeClass('hide');
            $('.sidebar-req-sec-thnk').addClass('show');
        }
    }
};
//url1 ajax 
ajaxObj.url = 'url1';
jQuery.ajax(ajaxObj);
//url2 ajax
ajaxObj.url = 'url2';
jQuery.ajax(ajaxObj);
