推荐答案

检查这个

Check this

<asp:Button ID="Buttonsubmit" runat="server" Text="Submit Query"
onclick="Buttonsubmit_Click" onclientclick="validate()" /> 

<asp:Button ID="Buttonsubmit" runat="server" Text="Submit Query"
onclick="Buttonsubmit_Click" onclientclick="return validate()" />

如果语法错误，还会检查浏览器是否有javascript错误然后不会调用此验证函数

also check your browser for javascript error if there is syntax error then this validation function will not be called
