JQuery.form.js plugin does not solve the connection timeout (timeout) reason Analysis and solution _jquery

JQuery.form.js is a form plugin that supports AJAX form submission and Ajax file uploads.

When you recently submitted a form that contains files using Jquery.form.js, you have a problem: when you run into a slow speed, and we set up timeout, for example:

var options = { 
timeout:3000//Limit requested time, jump out of request when request is greater than 3 seconds 

Our page will die here and post the results returned by the F12 developer tool:

At this point, we do not have a callback function to handle the error, and the example of Baidu is the only two callback functions:

Beforesubmit:showrequest,//Pre-submit callback function 
Success:showresponse,//Submit callback function

So, I go to the official Website View API, official website: http://malsup.com/jquery/form/#options-object, sure enough to find the callback function that handles the error:

The error
Callback function to is invoked upon error.

So that's what my options say:

var options = {
beforesubmit:showrequest,//Pre-submit callback function 
Success:showresponse,//Post successful callback function 
error: ShowError,///Post error callback function
timeout:3000//Limit request time, jump request when request is greater than 3 seconds

This is what the callback function says:

function ShowError (responsetext, statustext) {
if (statustext== ' timeout ') {
layer.msg ("Server busy, please try again later!") ", {icon:5,time:1500});
return;
}

The above is a small set to introduce JQuery.form.js plug-ins can not solve the connection timeout (timeout reason analysis and solutions, I hope to help you, if you have any questions please give me a message, small series will promptly reply to everyone.
