I have long script which can take few minutes to execute, so i decided to create an progressbar which will return current state.
But i have problem because xhr evt.loaded/evt.total (30/30) returns 1 (100%) before it start executing long script...
$(".systemform").live("submit",function(e) { //run system
run_system(); //start run system
e.preventDefault();
});
function run_system(){
$("#leftcontainer").html("");
$("#leftcontainer").show();
$("#chartContainer").hide();
$(".loading").show();
var sysid = $(".sysid:checked").val();
var oddstype = $(".odds_pref").val();
var bettypeodds = $(".bet_type_odds").val();
var bookie = $(".bookie_pref").val();
if (typeof oddstype === "undefined") {
var oddstype = $(".odds_pref_run").val();
var bettypeodds = $(".bet_type_odds_run").val();
var bookie = $(".bookie_pref_run").val();
}
$.ajax({
xhr: function () {
var xhr = new window.XMLHttpRequest();
xhr.upload.addEventListener("progress", function (evt) {
if (evt.lengthComputable) {
var percentComplete = evt.loaded / evt.total;
console.log(percentComplete);
$('.progress').css({
width: percentComplete * 100 + '%'

if (percentComplete === 1) {
$('.progress').addClass('hide');
}
}
}, false);

What is problem here???
when i console.log(evt) i get this: from upload progress:
ProgressEvent {isTrusted: true, lengthComputable: true, loaded: 30, total: 30, type: "progress"…}
from download progress:
system:302 ProgressEvent {isTrusted: true, lengthComputable: false, loaded: 28987, total: 0, type: "progress"…} system:302 ProgressEvent {isTrusted: true, lengthComputable: false, loaded: 104950, total: 0, type: "progress"…}
It looks like loaded is too large, what is my solution here???
I SOLVE IT by directly JQuery access to file instead php using $.get:
function refreshProgress(){
$.get('1_run.txt', function(data) {
console.log(data);
});
}
