问题 I need to change color of TextBox whenever its required field validator is fired on Clicking the Submit button 回答1: What you can do is register a Javascript function that will iterate through the global Page_Validators array after submission and you can set the background appropriately. The nice thing about this is that you can use it on all of your controls on the page. The function looks like this: function fnOnUpdateValidators() { for (var i = 0; i < Page_Validators.length; i++) { var val
