这里: http://json-taglib.sourceforge.net/index.html
下载个json-taglib.jar包,扔到WEB-INF/lib下,
jsp里:
<%@ taglib prefix="json" uri="http://www.atg.com/taglibs/json" %>
<json:object> <json:property name="itemCount" value="${cart.itemCount}"/> <json:property name="subtotal" value="${cart.subtotal}"/> <json:array name="items" var="item" items="${cart.lineItems}"> <json:object> <json:property name="title" value="${item.title}"/> <json:property name="description" value="${item.description}"/> <json:property name="imageUrl" value="${item.imageUrl"/> <json:property name="price" value="${item.price}"/> <json:property name="qty" value="${item.qty}"/> </json:object> </json:array> </json:object>
就会生成这样的格式了:
{ itemCount: 2, subtotal: "$15.50", items:[ { title: "The Big Book of Foo", description: "Bestselling book of Foo by A.N. Other", imageUrl: "/images/books/12345.gif", price: "$10.00", qty: 1 }, { title: "Javascript Pocket Reference", description: "Handy pocket-sized reference for the Javascript language", imageUrl: "/images/books/56789.gif", price: "$5.50", qty: 1 } ] }
