Question

我正在使用名为Metronic的bootstrap模板。下面的asp：LinkButton是简单的按钮控件。为了能够调用ServerSide事件处理程序（SubmitButton_Click），我将其转换为asp：LinkButton控件。但这一次它不会调用javascript代码。我试过OnClientClick。但是没有用。

的Login.aspx：

 <asp:LinkButton runat="server" ID="LinkButton1" CssClass="btn btn-default pull-right"
  onclick="SubmitButton_Click">Log In<i class="m-icon-swapright m-icon-white"></i>
 </asp:LinkButton>

<script>
    jQuery(document).ready(function () {
        App.init();
        Login.init();
    });
</script>

login.js的一部分：

var Login = function () {

return {
    //main function to initiate the module
    init: function () {

       $('.login-form').validate({
            errorElement: 'label', //default input error message container
            errorClass: 'help-inline', // default input error message class
            focusInvalid: false, // do not focus the last invalid input
            rules: {
..
..
}

Login.aspx.cs：

protected void SubmitButton_Click(object sender, EventArgs e)
{
   ..
}

Login.js：

var Login = function () {

return {
    //main function to initiate the module
    init: function () {

       $('.login-form').validate({
            errorElement: 'label', //default input error message container
            errorClass: 'help-inline', // default input error message class
            focusInvalid: false, // do not focus the last invalid input
            rules: {
                username: {
                    required: true
                },
                password: {
                    required: true
                },
                remember: {
                    required: false
                }
            },

            messages: {
                username: {
                    required: "Username is required."
                },
                password: {
                    required: "Password is required."
                }
            },

            invalidHandler: function (event, validator) { //display error alert on form submit   
                $('.alert-error', $('.login-form')).show();
            },

            highlight: function (element) { // hightlight error inputs
                $(element)
                    .closest('.control-group').addClass('error'); // set error class to the control group
            },

            success: function (label) {

使用jQuery选择器来处理由LinkButton呈现为HTML的锚点击，如下所示：

标记：

<asp:LinkButton runat="server" ID="LinkButton1" 
                CssClass="btn btn-default pull-right TheLinkButton"
                onclick="SubmitButton_Click">
    Log In<i class="m-icon-swapright m-icon-white"></i>
</asp:LinkButton>

注意：CssClass值已添加TheLinkButton，以允许使用点（.）表示法而不是ID（{{{{{ {1}}）选择器。这样做的主要原因是，当ASP.NET与母版页一起使用时，命名容器会破坏控件的ID，而类名不受影响。
