遍历jQuery列表中的JSON数组

问题描述：

我有这个JSON数组

// Json array
var productList = {"products": [
    {"description": "product 1", "price": "9.99"},
    {"description": "product 2", "price": "9.99"},
    {"description": "product 3", "price": "9.99"}
]
};

我希望它在我的列表视图中循环，但不知道如何执行此操作到目前为止，我所能做的就是一次列出一项.另外，我只能列出产品，而不能列出产品=价格. jQuery论坛实例正在帮助...谢谢!!

I want it to loop through my list view but have no idea how to do this all I can do so far is list one item at a time. Also, I can only list the product and not the product = the price. The jQuery forum inst helping... thanks !!

这是其余的代码

function loadList() {
//  var list = document.getElementById('productList');
    var list = $("#productList").listview();

    var listItem = document.createElement('li');
    listItem.setAttribute('id', 'listitem');

    listItem.innerHTML = productList.products[0].description;

    $(list).append(listItem);
    $(list).listview("refresh");

和HTML文件

<html xmlns:f="http://www.lipso.com/f" xmlns:l="http://www.lipso.com/v2/lml" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<head>
    <title>Page Title</title>
    &meta;
    <script src="@=site.cfg.resources.url@/test.js"></script>
</head>
<body onLoad="loadList()">
<div data-role="page">
    <div data-role="header" id="header">
        <h1>Dynamic Product List</h1>
    </div>
    <div data-role="content" id="content">
        <ul id="productList" data-role="listview" data-inset="true" data-theme="c" data-dividertheme="b">
        </ul>
    </div>
</div>
</body>
</html>

答

由于您已经在使用jQuery，为什么不使用 $.each()函数?

Since you're already using jQuery, why don't you use the $.each() function?

代替此代码:

var listItem = document.createElement('li');
listItem.setAttribute('id', 'listitem');

listItem.innerHTML = productList.products[0].description;

$(list).append(listItem);

使用此:

$(productList.products).each(function(index){
    $(list).append('<li id="listitem">' + this.description + " = " + this.price + '</li>');
});
