在javascript函数被触发onClientClick之前，CausesValidation为true

问题描述

我有一个文本框导致一旦链接按钮被触发就会导致冒犯，但是我已经调用了一个javascript函数OnclientClick并且在点击了linkBut​​ton后，CausesValidation正在工作...

让我成为一个特定的通过给出一个例子



Javascript代码：

Hi,I have textboxes that causesValidtion once linkbutton get fired if empty,but I have called a javascript function OnclientClick and the CausesValidation is working after the linkButton was clicked...
let me be specifik by giving an exemple

Javascript code:

function generateRandom() {
                $('#txtRefcode').val(random());
                alert('Reference Code: ' + $('#txtRefcode').val());
                return true;
            }
            function random() {
                return Math.floor(Math.random() * 10000000);
            }

Html代码：

Html code:

<asp:TextBox ID="txtsname" runat="server"  CssClass="TextBox-size">
<asp:RequiredFieldValidator ID="txtsnameRfValidator" runat="server" ErrorMessage="*" Text="Second Name is required" ControlToValidate="txtsname" Display="Dynamic">

<asp:LinkButton id="TigoCash" Cssclass="borderit" runat="server" OnClick="linkbuttonTigoCash_click" CausesValidation="true" OnClientClick="return generateRandom();" >

我想要的是，如果在调用generateRandom（）函数之前textbox为空，则causeValidation为true。

What I want is to causesValidation to true if textbox is empty before the generateRandom() function get called.
