多个控件的必需字段验证器问题
在提交表单的我的aspx页面中，我有以下html。
<p><asp:CheckBox ID="chkWishToDonateFrmTrust " runat="server" onclick="chkWishToDonateFrmTrustHandle(this)" />
Wish to donate from following Trust for future transactions</p><p> </p><p><textarea name="textarea" cols="45" rows="5" class="txtTrustDetails" runat="server"
id="txtTrustDetails" ></textarea></p>

<script type="text/javascript"> function validate(sender, args) { var checkBox = document.getElementById('<%=CheckBox1.ClientID %>'); var textBox = document.getElementById('<%=TextBox1.ClientID %>'); if (checkBox.checked == 1) { if (textBox.value == '') { args.IsValid = false; } else { args.IsValid = true; } } } </script> <asp:CheckBox ID="CheckBox1" runat="server" /> <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox> <asp:CustomValidator ID="CustomValidator1" ControlToValidate="TextBox1" runat="server" ErrorMessage="CustomValidator" ClientValidationFunction="validate"></asp:CustomValidator>草票
function chkValidate() { if($("#chkWishToDonateFrmTrust ").checked) { if($("#txtTrustDetails").val()=='') { args.IsValid = false; //your custom message according to you } }
