JavaScript implementation uploadify upload format and number limit _javascript skills

This article for everyone to share the JavaScript implementation uploadify upload format and the number of restrictions on the key code, I hope we study hard.

Key code One:

function DeleteUrl () {
   $ (' body '). On ("click", ". Img-wrap. Mask span", function (event) {
    event.stoppropagation ( );
          
    var qs=$ (' #file_upload-queue>div ');//All Queues
    var id=qs.eq (2). attr (' id '); the ID of the third queue
    $ (' # Uploadtowedaccredit '). Uploadify (' Cancel ', id);//This will do, automatically reset the number of queues and delete Dom objects, not directly Qs.eq (2). Remove (), invalid//
    if ( !window.confirm ("Are you sure you deleted the attachment?") ")) {return
      ;
    }
    var imgurl=$ (this). Parents (". Img-wrap"). FIND ("img"). attr ("src");
    DeleteImage (Imgurl);
    $ (this). Parents (". Img-wrap"). Remove ();
    */
  });
};

Key code two:

<li class= "Blockli clearfix" style= "padding-bottom:5px;" >
  <span class= "left-name" ><em class= "Red-star" >*</em> towage power of Attorney:</span>
  <div class= "Upload-wrap" style= "width:100px;" >
    <input type= "file" Name= "Uploadtowedaccredit" id= "Uploadtowedaccredit" class= "Filetext"/>
  </ div>
  <span id= "Uploadtowedaccreditlinktip" class= "warn-tips" ><em></em> please upload the attachment, upload the maximum ${ Towedaccreditpicmax} Zhang </span>
  <div id= "Towedaccreditdiv" class= "Up-img-list clearfix" ></div>
</li>

Key code Three:

        //upload complete ' onuploadcomplete ': function (file) {$ ('. Uploadify-queue '). html (');
    $ ("#uploadTowedAccreditLinkTip"). html (' <em></em> upload successful, pending submission ');
        },//Upload success ' onuploadsuccess ': function (file, data, response) {var obj = eval (' + data + ') ');
        var Result=obj.result;
          if (result== "true") {var filename=obj.filename;
          $ ('. Uploadify-queue '). html ('); $ (' #towedAccreditDiv ').

          ");
        Break Case-110:alert ("+file.name+"] size exceeds the system-limited "+$" (' #uploadTowedAccredit '). Uploadify (' Settings ', ' filesizelimit ') + Size
          ");
        Break Case-120:alert ("file [" +file.name+] size is abnormal!)
          ");
        Break Case-130:alert ("file [" +file.name+] type is incorrect!)
          ");
      Break 
      },////Upload failed//attachment format is incorrect, please upload jpg, BMP, PNG format file, size not exceeding 3MB ' onselecterror ': function (file, errorcode, errormsg) { 
      var msgtext = "Upload failed \ n"; Switch (errorcode) {case Swfupload.queue_error. Queue_limit_exceeded:var Towedaccreditdivlen = $ ("#towedAccreditDiv"). Children (). length; 
          Msgtext + = "Upload every time" + $ (' #uploadTowedAccredit '). Uploadify (' Settings ', ' uploadlimit ') + "files"; 
        Break Case Swfupload.queue_error. File_exceeds_size_limit:msgtext + = "File size exceeds limit (" + $ (' #uploadTowedAccredit '). Uploadify (' Settings ', ' Filesizelimi 
          T ') + ")"; 
        Break Case Swfupload.queue_error. 
          Zero_byte_file:msgtext + = "File size is 0"; 
        Break Case Swfupload.queue_error. 
          Invalid_filetype:msgtext + = "file format is incorrect, only" + $ (' #uploadTowedAccredit '). Uploadify (' Settings ', ' filetypeexts '); 
        Break 
      Default:msgtext + = "Error code:" + errorcode + "\ n" + errormsg;
    alert (Msgtext);
   
  }
  });
 Determine if the user has installed flash var obj = $ ("#uploadTowedAccredit"). Children (). EQ (0);
    if (obj.attr (' type ')!= "Application/x-shockwave-flash") {alert (' The system detects that your browser does not have a flash plugin installed, so that you can upload the image correctly, we recommend that you install Flash ');
  Return
} $ ("#uploadTowedAccredit"). CSS ("float", "left"); };

How JavaScript restricts the Uploadify upload format and number The problem I hope that through this article we should have a certain understanding, hope can really help you solve the uploadify upload number and format limitations of the problem.
