ajaxfileupload源码

ajaxfileupload的版本早就不更新了,ajaxFileUpload 报这错jQuery.handleError is not a function,是版本1.4.2之前的版本才有handlerError方法，之后就不存在了。需要添加此方法。

handleError: function( s, xhr, status, e )      {          // If a local callback was specified, fire it                  if ( s.error ) {                      s.error.call( s.context || s, xhr, status, e );                  }                    // Fire the global callback                  if ( s.global ) {                      (s.context ? jQuery(s.context) : jQuery.event).trigger( "ajaxError", [xhr, s, e] );                  }      }  

得到下面最全ajaxfileupload.js

jQuery.extend({    createUploadIframe: function(id, uri){//create frame            var frameId = 'jUploadFrame' + id;            var iframeHtml = '<iframe id="' + frameId + '" name="' + frameId + '" style="position:absolute; top:-9999px; left:-9999px"';if(window.ActiveXObject){                if(typeof uri== 'boolean'){iframeHtml += ' src="' + 'javascript:false' + '"';                }                else if(typeof uri== 'string'){iframeHtml += ' src="' + uri + '"';                }}iframeHtml += ' />';jQuery(iframeHtml).appendTo(document.body);            return jQuery('#' + frameId).get(0);    },    createUploadForm: function(id, fileElementId, data){//create formvar formId = 'jUploadForm' + id;var fileId = 'jUploadFile' + id;var form = jQuery('<form  action="" method="POST" name="' + formId + '" id="' + formId + '" enctype="multipart/form-data"></form>');if(data){for(var i in data){jQuery('<input type="hidden" name="' + i + '" value="' + data[i] + '" />').appendTo(form);}}var oldElement = jQuery('#' + fileElementId);var newElement = jQuery(oldElement).clone();jQuery(oldElement).attr('id', fileId);jQuery(oldElement).before(newElement);jQuery(oldElement).appendTo(form);//set attributesjQuery(form).css('position', 'absolute');jQuery(form).css('top', '-1200px');jQuery(form).css('left', '-1200px');jQuery(form).appendTo('body');return form;    },    handleError: function( s, xhr, status, e ) {    // If a local callback was specified, fire it    if ( s.error ) {    s.error.call( s.context || s, xhr, status, e );    }    // Fire the global callback    if ( s.global ) {    (s.context ? jQuery(s.context) : jQuery.event).trigger( "ajaxError", [xhr, s, e] );    }    },    ajaxFileUpload: function(s) {        // TODO introduce global settings, allowing the client to modify them for all requests, not only timeout        s = jQuery.extend({}, jQuery.ajaxSettings, s);        var id = new Date().getTime()        var form = jQuery.createUploadForm(id, s.fileElementId, (typeof(s.data)=='undefined'?false:s.data));var io = jQuery.createUploadIframe(id, s.secureuri);var frameId = 'jUploadFrame' + id;var formId = 'jUploadForm' + id;        // Watch for a new set of requests        if ( s.global && ! jQuery.active++ ){jQuery.event.trigger( "ajaxStart" );}                    var requestDone = false;        // Create the request object        var xml = {}           if ( s.global )            jQuery.event.trigger("ajaxSend", [xml, s]);        // Wait for a response to come back        var uploadCallback = function(isTimeout){var io = document.getElementById(frameId);            try {if(io.contentWindow){ xml.responseText = io.contentWindow.document.body?io.contentWindow.document.body.innerHTML:null;                 xml.responseXML = io.contentWindow.document.XMLDocument?io.contentWindow.document.XMLDocument:io.contentWindow.document; }else if(io.contentDocument){ xml.responseText = io.contentDocument.document.body?io.contentDocument.document.body.innerHTML:null;                xml.responseXML = io.contentDocument.document.XMLDocument?io.contentDocument.document.XMLDocument:io.contentDocument.document;}            }catch(e){jQuery.handleError(s, xml, null, e);}            if ( xml || isTimeout == "timeout") {                requestDone = true;                var status;                try {                    status = isTimeout != "timeout" ?

然后这样去调用，此处附上一段判断文件大小和文件类型的代码：

<input type="file" id="basicInfoHead" style="display:none;"  name="basicInfoHead" />    $('#basicInfoHead').change(function(){    var files = Array.prototype.slice.call(this.files);    var that=this;    files.forEach(function (file, i) {        if (file.size > 20 * 1024) {            alert("上传图片不能大于20k");            that.value = "";            return;        } else if (file.size == 0) {            alert("上传图片路径不正确（可能包含中文）");            that.value = "";            return;        }        if (!/\/(?:jpeg|png|gif)/i.test(file.type)){           alert("文件格式必须为jpeg,png,gif");return        }    })      $.ajaxFileUpload({           url:"",//需要链接到服务器地址            secureuri:false,           fileElementId:"basicInfoHead",//文件选择框的id属性           dataType: 'json',   //json           success: function (data) {              $("#imgHead").attr("src","/"+data.imagePath);           },          error:function(XMLHttpRequest, textStatus, errorThrown){              alert('上传失败！');           }        });
