AJAX响应时间

Question

How I can calculate AJAX response time? I need this in script, because I get back the server timestamp, but if the request take more than 1 second I need to add 1 second to the timestamp!

Answer 1

You need to get the start time (just before the AJAX request is done), and then the end time when the script is complete. You can than work out the difference, and if it's greater than 60 seconds, do your thing.

//Before the AJAX function runs
var startTime = new Date().getTime();

//Place this code inside the success callback of your AJAX function
var endTime = new Date().getTime();
if ((endTime - startTime) > (60 * 1000)) {
    //Took longer than 60 seconds
}
