ajax 后台获取String传入前台

ajax 后台获取String传到前台

1，页面调用ajax

new Ajax.Request('${ctx}/customer/card/creat-card-verifycode', {method: 'get',parameters: { contactId: cardHoldId },onComplete: function(dispatcher) {//TODO  分析ajax返回值}});

?

2,后台实现ajax

private List<String> virifyCodeList = new ArrayList<String>();public String ajax(){     virifyCodeList.add(String);     return "j:virifyCodeList"; }

?

3,前台获取值，分析

onComplete: function(dispatcher) {var virifyCodeList = dispatcher.responseText.evalJSON();$("verifyCode").value=virifyCodeList[0];}

?
