作法:验证过程中RequiredFieldValidator失败时调用javascript方法

问题描述

问题

是否可以使用RequiredFieldValidator在验证必填字段时出错时调用javascript函数?

我想调用javascript的原因是，如果发生必填字段验证错误，我将不希望隐藏加载图标.

Question

Is it possible to call javascript function on error in validation of the required field using RequiredFieldValidator?

The reason why i wanna call javascript is because i wan''t to hide loading icon if required field validation error occur.

推荐答案

function showLoadingIcon() {
if(Page_ClientValidate())
{
//show loading icon
}
else
{
//hide loading icon
}
}

PS:由于您只需要验证RequiredFieldValidators-对所有它们使用组名并按如下所示验证页面:

PS: Since you need to validate only the RequiredFieldValidators - use group name for all of them and validate the page as below:

if(Page_ClientValidate("GroupName")){
//Code Here
}
