[英]Continue an aborted AJAX (jqXHR) request
Is it possible to continue an aborted AJAX (jqXHR) request? 是否可以继续中止的AJAX(jqXHR)请求?
Something like: 就像是:
$(document).ajaxSend(function(event, jqXHR, ajaxOptions) {
if(/* it enters my conditions */) {
$.current_request = jQuery.extend(true, {}, jqXHR);
jqXHR.abort();
}
}
// some time in the future
$.ajax($.current_request)
This is not working, and I can see one problem that I do not know how to solve: no options are set when sending the request again. 这是行不通的,并且我看到一个我不知道如何解决的问题:再次发送请求时未设置任何选项。
Give it a try (not tested) 试试看(未经测试)
var request_queue = [], is_processing = false;
$(document).ajaxSend(function(event, jqXHR, ajaxOptions){
if(/* it enters my conditions */) {
jqXHR.abort();
request_queue.push(ajaxOptions);
}
else if (request_queue.length && !is_processing) {
is_processing = true;
while (ajaxOptions = request_queue.shift())
{
$.ajax(ajaxOptions);
}
is_processing = false;
}
});
$.ajax(theoptions)
它们当前存储在ajaxOptions参数中,您必须将其存储在全局某个位置以便以后访问(例如,在$ .current_request中)– Kevin B
