推荐答案

无法使用RequiredFieldValidator验证HTML控件.如果只想验证HTML控件客户端，则需要使用JavaScript.

RequiredFieldValidator仅用于服务器控件.

It''s not possible to validate a HTML control using RequiredFieldValidator. If you want to validate your HTML control client side only then you need to use JavaScript.

RequiredFieldValidator is used only for server controls.

您好，您可以使用javascript验证html文本框:

Hi, you can validate your html text box with javascript:

<input name="tel" id="tel" type="text" size="20" maxlength="200" style="width: 200px;"  önblur="checkTelRequired(this);" /><label>*</label>
<label id="telRequired" style="display: none;">Required</label>

function checkRequired(whatYouTyped) {
     var txtTel = whatYouTyped.value;
     var telRequired = document.getElementById("telRequired");
     if (txtTel == "") {
         telRequired.style.display = "";
         return false;
     }
     else {
         telRequired.style.display = "none";
     }
     return true;
}
