浏览器收到200ok时中止或标记ajax请求

Question

i have the following request

// =============================================== start()
//
// clicked_button : the user click the start button.
// app_path       : the app path
//
// return none.
//
var start = function(clicked_button, app_path) {

    $.ajax({
        type: 'POST',
        data: { 'app_path': app_path },
        url: '/app/start',
        context: clicked_button,
    })

    .done(function(data) {
        console.log(data);
        $(this).removeClass('btn-success');
        $(this).addClass('btn-danger');
        $(this).text('stop');
    })

    .fail(function(data) {
        console.log('failed to start the app: ' + data);
    })
};

the request is sent to the server, and the operation is done completely, i've tested it , the browser receive 200 OK, i've check it , but somehow the code in .done function is not executed, it's like the request is not completed yet.

how can i check if the browser receive a 200 ok, then just abort the ajax call, and continue the jquery code.

Answer 1

You dont need to do that.

You can just use the success function in ajax.

  $.ajax({
        type: 'POST',
        data: { 'app_path': app_path },
        url: '/app/start',
        context: clicked_button,
        success: function(data){
           console.log(data);
           $(this).removeClass('btn-success');
           $(this).addClass('btn-danger');
           $(this).text('stop');
        },
        error: function(data){
           console.log('failed to start the app: ' + data);
        }
    })

Try this code and check out you firebug for any problem!

使用dataType：'json'以获得服务器响应

Answer 3

i solved this problem by adding these lines to my php code:

sleep(1);
return Redirect::home();

why ?

after debugging the code, it look like all the operations that i request are completed, so the only problem is that the request is pending, or lost its way back, somehow ..

my best suggestion is because am using proc_open on my code ..

still not the best solution, but it is working and am half happy.
