关于ImageButton

Question

为什么我在ImageButton里写的 OnClientClick 的脚本方法没有触发啊？<td style="height: 26px; text-align:center;"><asp:ImageButton ID="Itnadddomain" runat="server" ImageUrl="~/images/user_09.gif" Height="19px" 
            OnClick="Itnadddomain_Click" Width="53px" OnClientClick="return checkName()" /></td>脚本方法：         function checkName()
         {
            alert("aaaa");
            var partn=/^[^\u4E00-\u9FA5]/g;
            var pattern = /^([\w-]+\.)+[\w-]+(/[\w-./?%&=]*)?$/;
            var name=document.getElementById("ctl00_ContentPlaceHolder1_Txtdomain").value; 
            alert(name);
            if(name!="yuip.net")
            {
                if(pattern.exec(name))
                {
                    if(!partn.exec(name))
                    {
                        alert("域名不能为中文！");
                        return false;
                    }
                }
                else
                {
                   alert("您输入的域名不规则！");
                   return false; 
                }
            }
            else
            {
                alert("此域名已被使用！");
                return false;
            }

Answer 1

请问LZ，你有调试吗？OnClientClick="return checkName()"改为OnClientClick="return checkName()；"试试

Answer 2

就连 alert("aaaa"); 都没有弹出来啊 ！！！
还是不行啊

Answer 3

应该是两个click事件冲突了！在pageload里面写代码Button1.Attributes.Add("onclick","javascript:return checkName()");试试！！

Answer 4

function checkName() 
        {  
if(Page_ClientValidate())   
      {   
            alert("aaaa"); 
            var partn=/^[^\u4E00-\u9FA5]/g; 
            var pattern = /^([\w-]+\.)+[\w-]+(/[\w-./?%&=]*)?$/; 
            var name=document.getElementById("ctl00_ContentPlaceHolder1_Txtdomain").value; 
            alert(name); 
            if(name!="yuip.net") 
            { 
                if(pattern.exec(name)) 
                { 
                    if(!partn.exec(name)) 
                    { 
                        alert("域名不能为中文！"); 
                        return false; 
                    } 
                } 
                else 
                { 
                  alert("您输入的域名不规则！"); 
                  return false; 
                } 
            } 
            else 
            { 
                alert("此域名已被使用！"); 
                return false; 
            }
