ASP.NET中的Java验证 [英] Javascript validations in asp .net

问题描述

朋友，

我在JavaScript验证中遇到问题，页面中有大约100英寸的文本框，并且所有文本框都是必填项，因此我想检查这些文本框.
您能帮我解决这个问题吗?我可以在提交时检查一个文本框.但是我无法一次检查所有文本框.我想为所有文本框重新使用相同的功能.

Hi Friends,

I have a problem in JavaScript validations, i have around 100''s of text-boxes in the page and all the text-boxes are compulsory , so i want to check the text-boxes.
could you please help me to resolve this problem. I am able to check one textbox on submit. but i am not able to check all the textboxes at once.I want to re-utilise the same function for all the text-boxes.

推荐答案

您好，


您可以编写一个检查验证的函数，并为事件"onfocusout"调用该函数.将文本框控件传递给该javascript函数.

示例代码

Hi,


You can write one function that checks the validtions, and call that function for the event "onfocusout".Pass the text box control to that javascript funtion.

sample code

<asp:texbox .....
onfocusout="Validatetextbox(this)" >  </asp:Textbox>





function Validatetextbox(this)
{
//your validation here
//ctrl.value gives the value in that textbox

}

希望这会有所帮助.

Hope this helps.
