功能结束后显示的MessageBox [英] MessageBox shown after function is over

问题描述

我有一个JavaScript函数调用我的javascript函数，我的功能就是这样：

I have a javascript function that calls my javascript function, my func islike this:

function sugParitValidation(){
   var isValid = false;
   Ext.MessageBox.confirm('  ','Are you sure you want to do this?',  function(btn){
      if(btn == 'yes'){
      isValid = true;
    }
 });
 return isValid ;
}

我的问题是 - if语句和返回状态正在发生，只有在显示确认窗口之后。
这样我就不能对用户选择的内容做出反应。
如何解决？尝试全部使用setTimeOut，没有任何改变....

My problem is - if statement and the return statment is happening, and only after that the confirm window being shown. That way I can't react to what the user choosed. how to solve this? tried allready use setTimeOut, no change at all....

推荐答案

我想你正在尝试这样做。 / p>

i think you are trying to do something like this.

someFunction(){
     if(sugParitValidation()){
          //todo something
     }
     else{
          //todo another thing
     }

}

你可以轻松地用回调来做这个。这是一个例子。

you can do this easyly with callbacks. This is the example.

someFunction(){
     var messageCallback = function(btn){
          if(btn === 'yes'){
               //todo something
          }
          else{
              //todo another thing
          }

     }
     Ext.MessageBox.confirm('  ','Are you sure you want to do this?', 
     messageCallback);
}
