前端实现导出以及下载

1.使用a标签跳转，触发a标签的click事件，提交

function exportFile(item){

        var url =
http+"/interface/exportApp?interfaceName="+interfaceName+"&startDate="+startDate+"&overDate="+overDate+"&pageNo="+pageNo+"&pageSize="+pageSize;
        console.log(url);
        document.getElementById("ifile").src=url;
        $(item).find("a").trigger("click");
    };

2.使用form表单提交,input里放参数

<form action="${pageContext.request.contextPath}/manager/exportAction/listPageData"method="get" id="search_form">
     <input type="hidden" id="areaType" name="areaType">
<input type="hidden" id="idList" name="idList">
<a class="btn btn-success" id="h-submitBtn" onclick="document:search_form.submit();" id="export">excel导出</ a>
</form>
