Jquery.form.js Resolution for connection Timeout (timeout) cannot be resolved

When I recently submitted a form that contains files using jquery.form.js, I ran into a problem: when we hit a slow speed and we set up timeout, for Example:

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

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

At this point, we do not handle the error callback function, and Baidu came out of the example of only these two callback functions:

Beforesubmit:showrequest,//pre-commit callback function
Success:showresponse,//post-commit callback function

so, I went to the official website to view the api, official Website: http://malsup.com/jquery/form/#options-object, and sure enough, I found the callback function to handle the error:

Error function to is invoked upon Error.

So my options are written like this:

var options = {       beforesubmit:showrequest,  // pre-commit callback function         success : showresponse,      // Post successful callback function          error:showerror,            //post-commit Error callback function
       timeout:3000               // limit the request time, when the request is greater than 3 seconds, jump out of the request
}

The callback function is written like this:

function showerror (responsetext, Statustext) {        if(statustext== ' timeout ') {             Layer.msg ("the server is busy, please try again Later!") ", {icon:5,time:1500});             return ;        }}

This is my solution, do not know the solution to your problem did not?
