问题
I am trying to upload large files using PLUpload library.at fileUploaded function I have ajax call to upload image to Amazon S3 but ajax call fails prompting error network connection aborted. Please help how to restart or resume my request
回答1:
First I detected the network is down or running perfectly fine using offline js
var run = function(){
Offline.check();
}
setInterval(run, 3000);
check every 3 seconds network connection available or not.
when network goes up after re-connection perform action at up function
Offline.on('up', function(){
if(ajax_response === null || ajax_response == 'error')
{
rename_file (oldname,newname)
}
});
store function parameters as global variables to use it for function call.
var ajax_response = null;
window.rename_file = function(oldname,newname)
{
var resp =null;
$.ajax({
url:'ajaxcall.php',
data:{action:'rename_file',new_name:newname,old_name:oldname},
async:false,
success:function(data,status)
{
resp = 'success';
},
error: function(jqXHR, textStatus, errorThrown) {
resp = 'error';
}
});
ajax_response.= resp;
return resp;
}
