在ajaxfileupload.js中找到if(window.ActiveXObject) { ****}替换为 if(window.ActiveXObject) { if($.support.leadingWhitespace){ var io = document.createElement('iframe'); io.id = frameId; io.name = frameId; }else{ var io = document.createElement('<iframe id="' + frameId + '" name="' + frameId + '" />'); if(typeof uri== 'boolean'){ io.src = 'javascript:false'; } else if(typeof uri== 'string'){ io.src = uri; } } }
