单个文本框可以有多个验证.......

问题描述

例如...
我有一个下拉列表作为client1 client2 client3 ........ client10
和一个文本框
&&
对于每个选定的dropdownitem文本框，是否应该执行不同的验证……

eg...
i have a dropdownlist as client1 client2 client3........client10
and one textbox
&&
for each selected dropdownitem textbox should perform different validations is it possible......

推荐答案

if(dropDownList1.SelectedIndex == 1)
{
  //call function say characterValidation();
}
else if(dropDownList1.SelectedIndex == 2)
   {
      //call function say numericValidation();
   }

等等.

function fnValidate(sender,args)
{
  var ddl = document.getElementById("dropdownList1");

 if(ddl.options.value == "client1")
 {
   var txt = document.getElementById("Textbox1");
   //validate text box

   args.IsValid=true; //based on the validation set the true or false.
 }
 elseif(ddl.options.value == "client2")
 {
   var txt = document.getElementById("Textbox1");
   //validate text box

   args.IsValid=true; //based on the validation set the true or false.
 }
return;
}
