进度条jquery没有被执行

Question

伙计们我使用这个插件来管理进度条，使用jquery＆amp; PHP https://github.com/drogus/jquery-upload-progress 这是我的JS文件： 1）jquery.js（Jquery lib 1.2.6） 2）jquery.uploadProgress.js（https://github.com/drogus/jquery-upload-progress/blob/master/jquery.uploadProgress.js） 3）另一个javascript文件，这是它的内容：

    $(document).ready(function(){

        //display new input until it exceed maximum input
        $('.file,.url').change(function(){
            var i = this.name.replace(/file|_/g,'');

            if( i >= number_of_uploads ){alert(LANG_MORE_F_FILES);return;};

            if(this.type == 'file') $('.file:eq('+ i +')').css('display', 'block');
            else $('.url:eq('+ i +')').css('display', 'block');
        });

        //display loader while upload files
        $('#uploader').submit(function(){
            $('#loadbox').css('display', 'block');
            $('#uploader').css('display', 'none');
        });
    $(".forget_pass1 a").attr('href','getpass');

    });

    //
    //javascript for captcha
    //
    function update_kleeja_captcha(captcha_file, input_id)
    {
        document.getElementById(input_id).value = '';
        //Get a reference to CAPTCHA image
        img = document.getElementById('kleeja_img_captcha'); 
         //Change the image
        img.src = captcha_file + '&' + Math.random();
    }

    //javascript for tabs
    function tabs(c1,c2,c3,c4){var m2,m3,l,t;var onclickf=function(){if(l<1)return 0;for(t=0;t<l;t++)if(m2[t]!=this){m2[t].className="";m3[t].style.display="none"}else{m2[t].className=c4;m3[t].style.display="block"}};var cl=function(){if(l<1)return 0;m2[0].className=c4;m3[0].style.display="block";for(t=0;t<l;t++)m2[t].onclick=onclickf};m2=$(c1+" "+c2+" li");if(m2[0]!="undefined"){m3=$(c1+" "+c3);l=m2.length;cl()}}$(document).ready(function(){var mah;mah=new tabs(".tabmain",".tabnav",".tabcon","tabactive")});

$(function() {
  $('form').uploadProgress({
    /* scripts locations for safari */
    jqueryPath: "jquery.js",
    uploadProgressPath: "pbar.js",
    /* function called each time bar is updated */
    uploading: function(upload) {$('#percents').html(upload.percents+'%');},
    /* selector or element that will be updated */
    progressBar: "#progressbar",
    /* progress reports url */
    progressUrl: "/progress",
    /* how often will bar be updated */
    interval: 1500
  });
});

我的HTML上传表单：

<!-- form upload -->
    <form id="uploader" name="uploader" action="{action}" method="post" enctype="multipart/form-data">

        <!-- upload boxes -->
        <div class="tabmain">
