在下面的代码中,我要做的就是从jQuery.ajax调用中获取HTTP响应代码.然后,如果代码为301(永久移动),则显示"位置"响应标头:

<script type="text/javascript">
function get_resp_status(url) {
$.ajax({
url: url,
complete: function (jqxhr, txt_status) {
console.log ("Complete: [ " + txt_status + " ] " + jqxhr);
// if (response code is 301) {
console.log ("Location: " + jqxhr.getResponseHeader("Location"));
// }
}
});
}
</script>
<script type="text/javascript">
$(document).ready(function(){
$('a').mouseenter(
function () {
get_resp_status(this.href);
},
function () {
}
);
}); …Run Code Online (Sandbox Code Playgroud)
