依賴js文件：
<!-- jQuery 核心文件 -->
<script src="../3rd/jquery/dist/jquery.js"></script>
<!-- ajaxFileUpload上傳插件 -->
<script src="../3rd/ajaxfileupload/ajaxfileupload.js" type="text/javascript"></script>html代碼：
<!-- ajaxFileUpload的上傳功能 -->
<div class="form-group">
<div class="col-sm-5">
<label for="file1">安裝包上傳</label>
<input class="form-control" type="file" id="file1" name="file" /><br />
</div>
</div>js代碼：
/* 上傳安裝包：ajax上傳插件使用 */
function ajaxFileUploadd() {
$.ajaxFileUpload
(
{
url: '/upgrade-release/rpc?method=/proHandRelea/uploadSetupPack', //用於文件上傳的服務器端請求地址
secureuri: false, //是否需要安全協議，一般設置爲false
fileElementId: 'file1', //文件上傳域的ID
dataType: 'json', //返回值類型 一般設置爲json
type: 'post',
success: function(data,status) //服務器成功響應處理函數
{
var dataJson = jQuery.parseJSON(data);
if(status == 'success') {
// 上傳成功
if(dataJson.resultMsg == 1) {
// 3、基本信息保存
submitBasicMsg();
}
if(dataJson.resultMsg == 0) { // 上傳失敗
doFalAlert("上傳文件失敗，發佈失敗！請重新上傳文件再發布！");
}
}
},
error: function (data, status, e)//服務器響應失敗處理函數
{
// alert(e);
doFalAlert("系統異常，上傳文件路徑異常！");
}
}
)
return false;
}注意問題：
可能會出現：上傳報錯 jQuery.handleError is not a function這個異常
分析並解決：handlerError只在jquery-1.4.2之前的版本中存在，jquery-1.4.2之後的版本中都沒有這個函數了。
因此在jquery高級版本中將這個函數添加上 ，問題解決。 以下是添加過handlerError方法的ajaxupload.js 文件，直接拿過去用即可。
