删除$('a.login-window').click(function() {(和对应}的 . 这样 DOM 就绪调用将打开它。您还需要更改var loginBox = $(this).attr('href');为var loginBox = $('.login-window').attr('href');.在 jQuery 1.7 中.live()已被弃用。并删除用于取消单击事件的第一个。当然，这将仅在加载时显示对话框而不是 onlick 但您确实说“我想在页面加载事件而不是单击时打开此对话框”，而不是“除了”。.on()return false;

jsFiddle 示例

// Getting the variable's value from a link 
var loginBox = $('.login-window').attr('href');

//Fade in the Popup and add close button
$(loginBox).fadeIn(300);

//Set the center alignment padding + border
var popMargTop = ($(loginBox).height() + 24) / 2;
var popMargLeft = ($(loginBox).width() + 24) / 2;

$(loginBox).css({
    'margin-top': -popMargTop,
        'margin-left': -popMargLeft
});

// Add the mask to body
$('body').append('<div id="mask"></div>');
$('#mask').fadeIn(300);

// When clicking on the button close or the mask layer the popup closed
$('a.close, #mask').on('click', function () {
    $('#mask , .login-popup').fadeOut(300, function () {
        $('#mask').remove();
    });
    return false;
});

只需删除初始化代码周围的点击处理程序：

$(document).ready(function(){

    // Getting the variable's value from a link 
    var loginBox = $(this).attr('href');

    //Fade in the Popup and add close button
    $(loginBox).fadeIn(300);

    //Set the center alignment padding + border
    var popMargTop = ($(loginBox).height() + 24) / 2; 
    var popMargLeft = ($(loginBox).width() + 24) / 2; 

    $(loginBox).css({ 
        'margin-top' : -popMargTop,
        'margin-left' : -popMargLeft
    });

    // Add the mask to body
    $('body').append('<div id="mask"></div>');
    $('#mask').fadeIn(300);

    // When clicking on the button close or the mask layer the popup closed
    $('a.close, #mask').on('click', function() { 
      $('#mask , .login-popup').fadeOut(300 , function() {
        $('#mask').remove();  
    }); 
});

此外，从 jQuery 1.9 开始，该live功能已被删除，因此您需要使用on。
