为什么此JavaScript会导致“权限被拒绝"? IE中的错误 [英] Why does this JavaScript cause a "Permission Denied" error in IE

问题描述

下面的代码在IE中引发Permission Denied错误，引用jQuery(1.6.2)第6244行Char:2:

The following code throws a Permission Denied error in IE, citing jQuery (1.6.2) line 6244 Char:2:

function addAgreement() {
    var url = window.location.toString();
    var pieces = url.split('/');
    var site_url = url.replace(pieces[pieces.length -1], '');
    $('.login').append('<div id="dialog"></div>');
    $('#dialog').load(site_url + '?page_id=443');
}

$('#dialog').dialog({
    width: 800,
    position: 'top',
    modal: true,
    buttons: {
        "Agree": function() { 
            agreed = true;
            var val = $('#registerform').attr('action') + '&agreed=1';
            $('#registerform').attr('action', val);
            $(this).dialog("close");
            $('#registerform').trigger('submit');
        }, 
        "Disagree": function() { 
            agreed = false;
            $(this).dialog("close"); 
        } 
    }
});

它在Firefox中有效-这与原产地政策有关吗? jQuery由Google CDN提供服务.

It works in Firefox — is this something to do with same origin policy? jQuery is being served by Google CDN.

更新 正在加载的内容是一个WordPress页面，其中还包含cufon-yui.js的包含内容(本地提供).我也尝试过在本地提供jQuery(即不是从Google CDN提供)，这没有什么区别.

UPDATE The content being loaded is a WordPress page which also contains includes for cufon-yui.js (served locally). I have tried serving jQuery locally too (i.e not from the Google CDN) and this made no difference.

更新2 从加载的页面中删除以下脚本标记可阻止该错误出现.

UPDATE 2 Removing the following script tags from the loaded page stops the error from appearing.

<script type='text/javascript' src='<?php echo bloginfo('template_url') ?>/inc/js/cufon-yui.js'></script> 
<script type='text/javascript' src='<?php echo bloginfo('template_url') ?>/inc/js/path/to/font.js'></script>
<script type='text/javascript'>
Cufon.replace('#page')('.title');
</script> 

推荐答案

对于AJAX请求，请访问www.被视为子域，并且违反了xmlhttprequestobject的同源策略.确保您的AJAX请求中的域与页面域和javascript文件相匹配.

For AJAX requests, www. is seen as a sub-domain and breaks the same-origin policy for the xmlhttprequestobject. Make sure the domain in your AJAX request matches the domain of the page and your javascript file.
