このようなイベントはありませんが、次のように ajax 呼び出し中に進行状況のパーセンテージを取得できます
$.ajax({
xhr: function()
{
var xhr = new window.XMLHttpRequest();
//Upload progress
xhr.upload.addEventListener("progress", function(evt){
if (evt.lengthComputable) {
var percentComplete = (evt.loaded / evt.total)*100;
//Do something with upload progress
var per= Math.round( percentComplete );
//per gives you percentage of progress
}
}, false);
//Download progress
xhr.addEventListener("progress", function(evt){
if (evt.lengthComputable) {
var percentComplete = (evt.loaded / evt.total)*100;
//Do something with download progress
var per= Math.round( percentComplete );
//per gives you percentage complete of process
}
}, false);
return xhr;
},
url:'your url here',
data:{'data':data},
type:"POST",
success:function(n){
//ajax completion handler
}
});
