用windchill原生API在前台直接下载文件

页面用的是MVC组件开发，然后页面有定义一个下载按钮

对应页面的后台jsp关键按钮和下载的代码如下：

	

		
*Part Number:
		

		

			

		
		

			Export--这个就是导出的按钮
		
	


对应的js方法如下：
function makeExcel() {
		var cover = document.getElementById('cover');
		cover.style.display = 'block';
		setTimeout(function() {
			cover.style.display = 'none';
			var rootNumber = PTC.jca.table.Utils.getExtTables()[0].store.data.items[0].data.number.gui.comparable;
			rootNumber=rootNumber.substr(1,rootNumber.length);
			var tempUrl = '<%=baseUrl%>netmarkets/jsp/ext/tct/partlistsearch/export.jsp?targetFile='+rootNumber;	
			PTC.util.downloadUrl(tempUrl);	
		}, 5000);
	}
那最主要的一行代码就是：PTC.util.downloadUrl(tempUrl);	

需要在action中配置下载的入口：

下载jsp的内容：

<%@page language="java" session="true" pageEncoding="UTF-8"%>
<%@ page import="wt.httpgw.URLFactory"%>
<%@ page import="ext.tct.globalamlsearch.util.ExportUtil"%>
<%@ taglib prefix="jca"
	uri="http://www.ptc.com/windchill/taglib/components"%>
<%@ taglib prefix="jcamvc"
	uri="http://www.ptc.com/windchill/taglib/jcaMvc"%>
<%@ taglib uri="http://www.ptc.com/windchill/taglib/mvc" prefix="mvc"%>
<%@ taglib prefix="wrap"
	uri="http://www.ptc.com/windchill/taglib/wrappers"%>
<%@ taglib tagdir="/WEB-INF/tags" prefix="wctags"%>
<%@ include file="/netmarkets/jsp/util/begin.jspf"%>



	 

	It could take a small amount of time, please waiting!

<%
URLFactory urlFactory = new URLFactory();
String baseUrl = urlFactory.getBaseURL().toExternalForm();
String targetFile = request.getParameter("targetFile");//用request得到 
System.out.println("targetFile="+targetFile);
ext.tct.partlistsearch.service.PartListSearchCommService.partListSearchDownload(response,targetFile);
response.flushBuffer();
out.clear();
out = pageContext.pushBody();
