[size=medium][b]我现在想做一个功能，就是在displaytag的“显示详情”这列，鼠标上移就显示相应productId对应产品的详细信息。
想在displaytag的“查看详情”这一列跳到js文件，该怎么写？和js文件中的这句话：var as = $("a[name=showProductDetail]");有关系吗？我想用a标签过去的。
我这样写能在js当中接收到productId的值吗？ 发到对应的action里应该怎么接收呢？
返回的内容可以在对应的showProductInfo div块里显示吗？
新手， 没有什么分数了，还是想请讲的明白点。

以下是productInfo.js：
[code="java"]$(document).ready(function () {
var infoNode = $("#showProductInfo");
var as = $("a[name=showProductDetail]");
infoNode.hide();
as.mouseover(function (event) {
var aNode = $(this);
var productId = aNode.attr("productId");
var myEvent = event || window.event;
infoNode.css("left", myEvent.clientX - 50 + "px").css("top", myEvent.clientY + 20 + "px");
var url = "showProductInfo.action?productId=" + productId;
$.get(url, null, function (data) {
infoNode.html(data);
infoNode.show();
});
});
as.mousemove(function (event) {
var myEvent = event || window.event;
infoNode.css("left", myEvent.clientX - 50 + "px").css("top", myEvent.clientY + 20 + "px");
});
as.mouseout(function () {
infoNode.hide();
});
});[/code]
action部分代码：
[code="java"]public String showProductInfo() throws Exception{
int productId=Integer.parseInt(request.getParameter("productId"));
this.productInfo = this.projectService.findProductInfobyProductId(productId);
StringBuilder result=new StringBuilder();
response.setContentType("text/html;charset=utf-8");
PrintWriter out=response.getWriter();
if (productInfo!= null) {
result.append("类型:"+productInfo.getType()+"<br>");
out.println(result);
}
else
{
out.println("wu");
}
return null;
}[/code]
