按钮onclick事件未触发onclientClick在Asp.net中返回true

Question

我在asp.net中加入简单的代码后点击onClick停止响应，当oclient点击返回true时请任何人建议......

 function loginEmpty() {
                debugger
                var flag = true;
                var name = document.getElementById("username").value;
                var pass = document.getElementById("userpassword").value;


            if (name =='' || pass =='') {

               document.getElementById('username').style.border = "solid 1px red";
               document.getElementById('userpassword').style.border = "solid 1px red";

               document.getElementById('loginMsg').style.display = "none";
               document.getElementById('errorMsg').style.display = "block";
               document.getElementById('errorMsg').innerHTML = "Required field can not leave blank.";
               flag= false;

            }
            else {

                flag = true;
                document.getElementById('username').style.border = "solid 1px green";
                document.getElementById('userpassword').style.border = "solid 1px green";
                document.getElementById('errorMsg').innerHTML = "   . ";

            }
            return flag;

        }

例如，下面是您的按钮：

在调用JavaScript方法之前添加return，如下面示例所示：

<asp:Button runat="server" Text="My Button" ID="myButton" OnClientClick="return loginEmpty();" OnClick="myButton_OnClick" />
