从jquery模型确认或模型对话框返回值

i have a javascript function like this:

我有这样的javascript函数：

Javascript:

使用Javascript：

function dailog_box(){
    $( "#dialog-confirm" ).dialog({
        resizable: false,
        modal: true,
        buttons: {
            Ok: function() {
            $( this ).dialog( "close" );
            return true;   //i want to return value here
        },
            Cancel: function() {
            $( this ).dialog( "close" );
            return false;  //i want to return value here
            }
        }
    });
}

Html

HTML

<div id="dialog-confirm" title="Prescriptions" style="display:none;">
    <p>
        <span class="ui-icon ui-icon-alert" style="float: left; margin: 0 7px 20px 0;"></span>
        These items will be permanently deleted and cannot be recovered. Are you sure?<br/>
        <input type="checkbox" name="check_od" id="check_od"/> The prescription is correct;
    </p>
</div>

After calling the dialog_box() function i want the returned value in the variable flag and i did like this:

在调用dialog_box（）函数后，我希望变量标志中返回的值，我喜欢这样：

Javascript

使用Javascript

 var flag = dailog_box();
 alert(flag);

But the result was undefined. and also the alert happens before i click any button. so what should i do to get the value after any button is clicked in the model's button

但结果未定义。并且在我点击任何按钮之前发生警报。那么在模型按钮中单击任何按钮后，我该怎么做才能获得该值

For further information you can check http://jsfiddle.net/8e388/13/ I want the returned value to be alerted. by the way im new to jsfiddle.

2 个解决方案

I suggest you use callback.

我建议你使用回调。

buttons: {
            Ok: function() {
            callbackSuccess();
            $( this ).dialog( "close" );
        },
            Cancel: function() {
            callbackCancel();
            $( this ).dialog( "close" );
            }
        }

callbackSuccess and callbackCancel - is simple function

callbackSuccess和callbackCancel - 是一个简单的函数

If you create helper for ConfirmDialog it will be easier to pass the callback

如果为ConfirmDialog创建帮助器，则更容易传递回调

You cannot have it exactly as you like. You can do this though using another way :

你无法完全按照自己的意愿拥有它。您可以使用其他方式执行此操作：

Check out my fiddle

看看我的小提琴

Basically I have a global variable feedback

基本上我有一个全局变量反馈

var feedback = false;

And on ok or cancel of the dialog, I set the appropriate value. IMO this adds some more flexibility in your code

在确定或取消对话框时，我设置了适当的值。 IMO为您的代码增加了一些灵活性
