How can I get jQuery to perform a synchronous, rather than asynchronous, Ajax request?

Question

How can I get jQuery to perform a synchronous, rather than asynchronous, Ajax request?

I have a JavaScript widget that gives standard extension points. One of them is the before creating function. It should return bogus to keep a thing from being made.

I've added an Ajax call into this capacity utilizing jQuery:

beforecreate: function (node, targetNode, type, to) {

  jQuery.get('http://example /catalog/create/' + targetNode.id + '?name=' + encode(to.inp[0].value),



  function (result) {

    if (result.isOk == false) 

        alert(result.message);

  });

}

Be that as it may, I need to keep my gadget from making the thing, so I should return bogus in the mother-function, not in the callback. Is there an approach to play out a simultaneous AJAX demand utilizing jQuery or some other in-program API?

From the jQuery documentation: you specify the asynchronous option to be false to get a synchronous Ajax request. Then your callback can set some data before your mother function proceeds.

Here's what your code would look like if changed as suggested:



beforecreate: function (node, targetNode, type, to) {

    jQuery.ajax({

        url: 'example_url/catalog/create/' + targetNode.id + '?name=' + encode(to.inp[0].value),

        success: function (result) {

            if (result.isOk == false) alert(result.message);

        },

        async: false

    });

}

Try this :

function getURL(url){

    return $.ajax({

        type: "GET",

        url: url,

        cache: false,

        async: false

    }).responseText;

}

//example use

var msg=getURL("message.php");

alert(msg);
