Third, Ajax upload files

When it comes to Ajax uploading files, previous articles have also been said (see: JS Learning 32:html5 Drag-and-drop pictures batch Ajax no refresh progress upload). When Ajax uploads, you need to get Input:file selected files (possibly multiple files) and get a list of their files as:

// input标签的files属性document.querySelector("#fileId").files// 返回的是一个文件列表数组

Get a list of the files and then iterate through the insert into the form data. That

Get the upload file Dom objectVarOfiles=Document.Queryselector("#fileId");Instantiate a form data objectVarFormData= New FormData();Traverse the list of picture files and insert them into the form datafor  (var  I = 0 File; file = ofiles< Span class= "pun" >[i]; I++)  { //file name, file object  FormData append (file. Name, File               /span>                

Once you get the form data, you can upload it using Ajax post.

Instantiate an Ajax objectVarXhr= New XMLHttpRequest();xhr.= function ()  Span class= "pun" >{ Alert ( "upload success!) "}xhr. Open ( "POST" ,  " upload.php ", true); //send form data xhr.formdata        

After uploading to the server, get to the list of files:

Array(    [Jpg_jpg] = Array ( [Name] =Jpg.Jpg[Type] =Image/Jpeg[Tmp_name] =D:\xampp\tmp\phpa595.Tmp[Error] = 0 [Size] = 133363 ) [Png_png] = Array ( [Name] =Png.Png[Type] = = image/png [Tmp_name] +  D:\xampp\tmp\phpa5a6 . tmp [error] = 0 [size] + =  1214628 ))               

Loop through the array on the server to upload the file.
