struts2的Action方法中，直接输出js代码

junjun19860702

一、Action直接输入js代码
struts2的Action方法，可以没有返回值，void，然后直接out.write("<script>js代码</script>")
out.println("<script>js代码</script>")
 
/** * 单个修改价格 * @return * @author mengxianjun * @throws Exception  * @date 2011-4-25 上午09:30:53 */public void updatePrice() throws Exception{TCommissionId tCommissionId = new TCommissionId();tCommissionId.setProductNum(productNum);tCommissionId.setTypeNum(typeNum);commission = priceStrategyService.queryTCommissionById(tCommissionId);/*按价格修改，else按比率修改*/if( "prices".equals(updateType) ){fastPriceOrRatio = DoubleConvert.getDoubleByFastPrice(fastPriceOrRatio);Double fastCommission = DoubleConvert.getDoubleByFastCommission((money[0])-fastPriceOrRatio);commission.setFastCommission(fastCommission);commission.setFastPrice(fastPriceOrRatio);commission.setAlterDate(new Date());//修改时间commission.setEmployeeId(getEmpID());//处理工号priceStrategyService.updateTCommission(commission);}else{Double fastPrice = DoubleConvert.getDoubleByFastPrice((money[0])*fastPriceOrRatio);//通过比率算出实际价格Double fastCommission = DoubleConvert.getDoubleByFastCommission((money[0])-fastPrice);//面值-实际价格，得到佣金commission.setFastCommission(fastCommission);commission.setFastPrice(fastPrice);commission.setAlterDate(new Date());//修改时间commission.setEmployeeId(getEmpID());//处理工号priceStrategyService.updateTCommission(commission);}this.getResponse().setContentType("text/html;charset=UTF-8");this.getResponse().setCharacterEncoding("UTF-8");PrintWriter out = this.getResponse().getWriter();out.println("<script>alert('修改成功！');history.go(-2);window.location.reload(true);</script>");out.flush();out.close();return null;} 
二、AJAX提交，Struts2的Action返回json数据
/** * 验证业务密码--ajax方式 * @author mengxianjun * @throws IOException  * @date 2011-6-13 下午01:33:03 */public void checkPwd2() throws IOException{PrintWriter out = this.getResponse().getWriter();String vp = "false";if( valiPass(password2) ){vp = "true";out.write("{\"msg\":\""+vp+"\"}");//反斜杠转义}else{vp = "false";out.write("{\"msg\":\""+vp+"\"}");//反斜杠转义}}
