下拉列表在Page_ClientValidate()之后不会回发

I have just found the solution. The following function works (remove the else part):

我刚刚找到了解决办法。以下功能工作(删除else部分):

function confirmSubmit() {
     if (Page_ClientValidate("Group1")) {
         return window.confirm("Are you sure to submit the form?");
     } 
 }

But I am wondering why it doesn't work when I add the else part.

但是我想知道为什么当我添加else部分时它不能工作。

问题:

I want to have a confirm dialog after user fills in all the data in the form. I set onclientclick="return confirmSubmit()" in the submit button.

在用户填写表单中的所有数据后，我希望有一个确认对话框。我在submit按钮中设置onclientclick=“return confirmSubmit()”。

 function confirmSubmit() {

     if (Page_ClientValidate("Group1")) {
         return window.confirm("Are you sure to submit the form?");
     } else {

         return false;
     }
 }

If Page_ClientValidate("Group1") returns false, the dropdownlist doesn't cause postback after I first select the item, and the postback only occurs when I select the dropdownlist second time.

如果Page_ClientValidate(“Group1”)返回false，那么在我第一次选择该项目后，dropdownlist不会导致回发，而回发只发生在我第二次选择dropdownlist时。

What's the problem?

是什么问题?

After Page_ClientValidate is called, the variable Page_BlockSubmit gets set to true, which blocks the autopost back. Page_BlockSubmit was getting reset to false on the second click, for what reasons I still don't fully understand. I'm looking more into this, but I have a solution and I'm under the gun so I'm rolling with it....

在调用Page_ClientValidate之后，变量Page_BlockSubmit被设置为true，这将阻塞autopost。Page_BlockSubmit在第二次点击时被重置为false，原因是我仍然不能完全理解。我想更多,但是我有一个解决方案,我枪下我用它滚动....

Just add below code in the code block which executes if Page is not valid.

只要在代码块中添加以下代码，如果页面无效，代码块将执行这些代码。

Page_BlockSubmit = false;

e.g.

如。

function ValidatePage() 
{
    flag = true;
    if (typeof (Page_ClientValidate) == 'function') 
    {
        Page_ClientValidate();
    }

    if (!Page_IsValid) 
    {
        alert('All the * marked fields are mandatory.');
        flag = false;
        Page_BlockSubmit = false;
    }
    else 
    {
        flag = confirm('Are you sure you have filled the form completely? Click OK to confirm or CANCEL to edit this form.');    
    }
    return flag;       
}
