JS implements scheduled tasks to request background setInterval timing and ajax request issues every N seconds
This article mainly introduces JS to implement scheduled tasks to request the background every N secondssetInterval timing and ajax request related JS information, friends who are interested in js can refer to this article
Look at the following piece of code first:
DiGui = function (param) {
$.ajax({
success: function (returnValue) {
window.setInterval("fnSetMarkPoint()", 5000);
}
});After calling the DiGui() method
Problem: Create a setInterval every 0.1 seconds in a tree shapeLoopCreate setInterval until the page crashes
Solution: Ensure that setIntervalobject is only created once
Implementation plan: Define a Boolean variable for judgment var status= true;
var status = true;
DiGui = function (param) {
$.ajax({
success: function (returnValue) {
if (status) {
status= false;
window.setInterval("DiGui()", 5000);
}
}
});The above is the JS implementation of scheduled tasks introduced by the editor to request background setInterval timing and ajax request issues every N seconds. I hope it will be helpful to everyone! !
