页面回退异常，不好意思，没有分了

[lilyfeng2011]

jsp中写了一个a标签，在后面写了一段代码如下： $('#back')
.click(
function() {
var urlStr = new $.Template(
"${contextPath}<card:constant fieldName="CARD_INSSURENCE_DECLARE_URL" shortClassName="Url"/>");
var urlParam = {
"activeno" : "${activeno}"
};
var url = urlStr.expand(urlParam);
window.location.href = url;
});
回退到上一页。actionno是上一页传过来的参数。页面提交方式为post,上一个页面的传递方式是get。但是老报错，如下：
