偶尔Ajax响应错误{readyState的= 0，状态= 0，状态文本=＆QUOT;错误＆QUOT;}使用jQuery [英] Occasional ajax response error { readyState=0, status=0, statusText="error"} using jquery

问题描述

我已经运行与使用jQuery（和ColdFusion服务器端）Ajax响应的问题。有时工作，有时没有。当我测试了服务器端组件直接调用它 - 它始终工作，所以我想这个问题是与Ajax响应。我得到的SERVERURL，直接从服务器 - 因此它不应该是一个跨域的问题。我只是显示和隐藏DIV-标记，以便它不应该是不确定的URL，然后Ajax响应已被处理。我拉出很多头发了这一点。

I have run into a problem with the AJAX response using jquery (and coldfusion serverside). Sometimes it works and sometimes it doesn't. When I test the serverside component calling it directly - it always works, so I guess the problem is with the ajax response. I get the serverurl, directly from the server - so it shouldn't be a cross-domain issue. I just show and hide div-tags so it shouldn't be about relocating the url before the ajax response has been processed. I am pulling out a lot of hair over this.

在code为addTask方式：

The code for the addTask method:

function addTask(){
var priority = $('#ff-add-task-priority').length > 0? $('#ff-add-task-priority').val() : 0;

$.ajax({
        url: settings.server+'/c/Tasks.cfc?method=addTask',
        data: { userid: settings.userid, 
                taskname: $('#ff-add-task-name').val(),
                tasknote: $('#ff-add-task-note').val(),
                completed: $('#ff-add-task-completed').val(),
                priority: priority,
                },
        type: 'POST',
        dataType: 'json',
        success: function(response) {
            var output = addRow(response, $('#ff-add-task-name').val(), 0,0);
            $('#data-list-tasks').append(output);

            $('#main').children().addClass('hide');
            $('#section-list-tasks').removeClass('hide');
            resetForm($('#add-task-form'));
            //route('#section-list-tasks');
        },
        error: function(ErrorMsg) {
           console.log('Error', ErrorMsg);
        }

    });

}

Firebug的输出显示了AJAX调用，有时作品，有时失败：

Firebug output shows that the AJAX calls works sometimes and sometimes it fails.:

推荐答案

我认为你需要的数据参数报价是这样的：

I think you need quotes in the data parameter like this:

data: { 'userid': settings.userid, 
        'taskname': $('#ff-add-task-name').val(),
        'tasknote': $('#ff-add-task-note').val(),
        'completed': $('#ff-add-task-completed').val(),
        'priority': priority,
      },

看看是否有帮助。

See if that helps.
