成功的AJAX功能完成前没有发生 [英] success function not occurring before AJAX complete

问题描述

我想使用jQuery的对话框箱 beforeClose 功能。我检查，看看用户表单数据格式正确，如果没有，返回假到 beforeClose ，所以用户可以重新输入信息。

I am trying to use the jQuery dialog box beforeClose feature. I am checking to see if user form data is formatted properly and if not, returning false to the beforeClose, so the user can re-enter information.

该对话框code调用函数 submituserupdateform 的 beforeClose ：

The dialog box code calls the function submituserupdateform in the beforeClose:

.dialog({beforeClose: function () {
  formresult=submituserupdateform($('#myaccountdialog').find('form'));
  if (formresult !="okay"){
    return false;
 }
}})

的 submituserupdateform 功能检查，看看是否有在code的错误：

The submituserupdateform function checks to see if there was an error in the code:

function submituserupdateform($tgt){
  var url='./includes/admin/user/myaccount.php';
  $.ajax({
      type: "POST",
      url: url,
      data: $tgt.serialize(),
      success: function(data){
        $("#myaccountdialog").html(data);
        if ($('.error').length){
          var myresult= "notokay";
        } else {
          var myresult ="okay";
        }
      },
      dataType: "html"
    });
   return myresult;
}

我已搜查，并从Ajax调用发现返回值？，但我我已经设定 myresult 我成功的回调中。我也曾尝试 ajaxComplete ，的ajaxSuccess ， .done 。据控制台，什么我都试过套 myresult ;我总是以结束：

I have searched, and found Return value from ajax call?, but I am already setting myresult inside my success callback. I have also tried ajaxComplete, ajaxSuccess, .done. According to the console, nothing I have tried sets myresult; I always end up with an:

未捕获的Ref​​erenceError：MyResult是一个判定没有定义

这必须是一个简单的错误，请帮助我，如果你看到我的错！

This must be a simple error, please help me if you see my mistake!

推荐答案

AJAX的异步行为将使阿贾克斯成功callback-之前，请函数返回（那是你不想要的东西的）

The asynchronous behaviour of ajax will make your function return before the ajax success callback- (that is what you don't want)

您可以添加异步：假

 var myresult ="":
 $.ajax({
      type: "POST",
      url: url,
      data: $tgt.serialize(),
      async:false,
      success: function(data){
