سلام.
من کد اپلود عکسو پیدا کردمو جواب داد اما نفهمیدم چجوری یه تکست باکسو با متد پستم همراش بفرستم!
یه سوال مهم : اگه طرف بیاد کدای جاوا اسکریپتو غیر فعال کنه که دیگه سایت از کار میفته و چیزی ارسال نمیشه پس چرا میگن ajax خوبه؟؟
این کد جاوا
// JavaScript Document
$(document).ready(function() {
var options = {
target: '#output', // target element(s) to be updated with server response
beforeSubmit: beforeSubmit, // pre-submit callback
success: afterSuccess, // post-submit callback
uploadProgress: OnProgress, //upload progress callback
resetForm: true // reset the form after successful submit
};
$('#MyUploadForm').submit(function() {
$(this).ajaxSubmit(options);
// always return false to prevent standard browser submit and page navigation
return false;
});
//function after succesful file upload (when server response)
function afterSuccess()
{
$('#submit-btn').show(); //hide submit button
$('#loading-img').hide(); //hide submit button
$('#progressbox').delay( 2000 ).fadeOut(); //hide progress bar
}
//function to check file size before uploading.
function beforeSubmit(){
}
//progress bar function
function OnProgress(event, position, total, percentComplete)
{
//Progress bar
$('#progressbox').show();
$('#progressbar').width(percentComplete + '%') //update progressbar percent complete
$('#statustxt').html(percentComplete + '%'); //update status text
if(percentComplete>50)
{
$('#statustxt').css('color','#000'); //change status text to white after 50%
}
}
});
اینم کد ایندکس
