How to upload file through Jquery/AJAX
提问by denlau
I am currently POSTING my form through AJAX with the following code:
我目前正在使用以下代码通过 AJAX 发布我的表单：
$(document).ready(function(){
$("form#createForm").submit(function() { // loginForm is submitted
$("form#createForm input#createForm_submit").attr('disabled','disabled');
tinyMCE.triggerSave();
$.ajax({
type: "POST",
dataType: "json",
url: "perform", // URL of the Perl script
data: $("#createForm").serialize(),
// script call was successful
// data contains the JSON values returned by the Perl script
success: function(data){
$('div.form-group').each(function(){
$(this).removeClass('has-error');
});
if (data.error) { // script returned error
var myList = $('ul.msg-list').empty();
$.each(data.msg, function(key,item) {
$("div."+key).addClass('has-error');
$('<li>').text(item.errtxt).appendTo(myList);
});
$('div#create_createresult').html('some error').html(myList);
$('div#create_createresult').addClass("text-danger");
$("form#createForm input#createForm_submit").removeAttr('disabled');
} // if
else
{ // login was successful
//$('form#login_loginform').hide();
$('div#create_createresult').text(data.msg);
$('div#create_createresult').addClass("success");
} //else
} // success
}); // ajax
$('div#login_loginresult').fadeIn();
return false;
});
});
Now I want to add the posibility of uploading a picture in the same form and just implement it in this JQUERY and in the same server-side script. My only problem is, I don't know how to do it.. I have tested the above, and I find, that it doesn't pass the $_FILES-variable to my server side script.
现在我想添加以相同形式上传图片的可能性，并在此 JQUERY 和相同的服务器端脚本中实现它。我唯一的问题是，我不知道该怎么做。我已经测试了上面的内容，我发现它没有将 $_FILES 变量传递给我的服务器端脚本。
Can anyone lead me in any direction of, what I need to do, to add the possibility of image upload with this script?
任何人都可以引导我朝着我需要做的任何方向添加使用此脚本上传图像的可能性吗？

try to use this.
尝试使用这个。
// grab your file object from a file input
$('#fileInput').change(function () {
sendFile(this.files[0]);
});
// can also be from a drag-from-desktop drop
$('dropZone')[0].ondrop = function (e) {
e.preventDefault();
sendFile(e.dataTransfer.files[0]);
};
function sendFile(file) {
$.ajax({
type: 'post',
url: '/targeturl?name=' + file.name,
data: file,
success: function () {
// do something
},
xhrFields: {
// add listener to XMLHTTPRequest object directly for progress (jquery doesn't have this yet)
onprogress: function (progress) {
// calculate upload progress
var percentage = Math.floor((progress.total / progress.totalSize) * 100);
// log upload progress to console
console.log('progress', percentage);
if (percentage === 100) {
console.log('DONE!');
}
}
},
processData: false,
contentType: file.type
});
}
