Why does this JavaScript cause a "Permission Denied" error in IE
提问by codecowboy
The following code throws a Permission Deniederror in IE, citing jQuery (1.6.2) line 6244 Char:2:
以下代码Permission Denied在 IE 中引发错误，引用 jQuery (1.6.2) 第 6244 行 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");
}
}
});
It works in Firefox — is this something to do with same origin policy? jQuery is being served by Google CDN.
它适用于 Firefox — 这与同源策略有关吗？jQuery 由 Google CDN 提供服务。
UPDATEThe 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.
更新正在加载的内容是一个 WordPress 页面，其中还包含用于cufon-yui.js（在本地提供）的内容。我也尝试过在本地提供 jQuery（即不是来自 Google CDN），这没有任何区别。
UPDATE 2Removing the following script tags from the loaded page stops the error from appearing.
更新 2从加载的页面中删除以下脚本标记可阻止错误出现。
<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>

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.
对于 AJAX 请求，www. 被视为子域并破坏了 xmlhttprequest 对象的同源策略。确保您的 AJAX 请求中的域与页面和您的 javascript 文件的域匹配。
