ASP.NET waitCursor更改为DropDownList [英] ASP.NET waitCursor changes over DropDownList

问题描述

我希望页面执行回发时将光标更改为waitcursor.
我将javascript函数放在-Section中:

Hi,
I want the cursor to change to waitcursor while my page is doing postback.
I put the javascript function in -Section :

  function setHourglass()
{
  document.body.style.cursor = ''wait'';
}

并在Form-Tag中:

and in Form-Tag:

<form id="form1" runat="server" onsubmit="return PleaseWait();"></form>

但是它可以正常工作:如果光标在DropDownList上，它会变回正常状态.从DropDownList移开后，它将更改回waitcursor，直到完成回发.

在我的应用程序中，我有几个依赖的dropdownfields，每个都具有autopostback = true.我希望用户在第一个DropDownList完成自动回发之前不要从以下DropDownList中进行选择.但是用户会自动将鼠标移到下面的DropDownList上，然后光标不再是waitCursor.

我该怎么办?

It works fine BUT: if the cursor is over a DropDownList it changes back to normal. Moving away from the DropDownList it changes back to waitcursor until postback is done.

In my application I have several depending dropdownfields each with autopostback=true. I want the user not to select from the following DropDownList before the first DropDownList has finished autopostback. But the user automatically moves the mouse over the following DropDownList - and the cursor is then not a waitCursor.

What can I do?

推荐答案

不要依靠光标来阻止用户单击您不希望其单击的位置.禁用从属下拉菜单，直到做出正确的选择为止.我会使用AJAX来完成此任务，而不是依靠回发

Don''t rely on the cursor to stop a user from clicking where you don''t want them to. Disable the dependent dropdowns until the proper selections have been made. I would use AJAX to accomplish this rather than relying on postbacks
