Question

我正在尝试将json解析为ul li。这是我的json：

var data = {"resultDescription":"SUCCESS","data":[{"orderNum":"A000","userName":"Oswaldo","value":504.74,"qty":3.0},{"orderNum":"A001","userName":"Mao","value":529.17,"qty":6.0},{"orderNum":"A002","userName":"Angeline","value":553.6,"qty":9.0},{"orderNum":"A003","userName":"Gerardo","value":578.03,"qty":12.0},{"orderNum":"A004","userName":"Nicki","value":602.46,"qty":15.0}]}

我试图用该代码解析它：

$.each(data.data, function (index, item) {
                html += "<ul>";
                console.log(item);
                $.each(item.data, function (index1, item1) {
                    html += "<li>" + orderNum + "</li>";
                    html += "<li>" + qty + "</li>";
                    html += "<li>" + userName + "</li>";
                    html += "<li>" + value + "</li>";
                });
                html += "</ul>";
            });

我做错了什么？

Answer 1

为什么还有$.each

$.each(item.data, function (index1, item1) {

见下文。 演示：

var data = {"resultDescription":"SUCCESS","data":[{"orderNum":"A000","userName":"Oswaldo","value":504.74,"qty":3.0},{"orderNum":"A001","userName":"Mao","value":529.17,"qty":6.0},{"orderNum":"A002","userName":"Angeline","value":553.6,"qty":9.0},{"orderNum":"A003","userName":"Gerardo","value":578.03,"qty":12.0},{"orderNum":"A004","userName":"Nicki","value":602.46,"qty":15.0}]}

var html = "";
			$.each(data.data, function (index, item) {
				html += "<ul>";
				console.log(item);
				//$.each(item.data, function (index1, item1) {
					html += "<li>" + item.orderNum + "</li>";
					html += "<li>" + item.qty + "</li>";
					html += "<li>" + item.userName + "</li>";
					html += "<li>" + item.value + "</li>";
				//});
				html += "</ul>";
			});
			setTimeout(function() {
				$(".container").append(html);
			}, 1500);

<script src="//ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="container"></div>

Answer 2

var html = "";
$.each(data.data, function (index, item) {
    html += "<ul>";
    console.log(item);
    html += "<li>" + item.orderNum + "</li>";
    html += "<li>" + item.qty + "</li>";
    html += "<li>" + item.userName + "</li>";
    html += "<li>" + item.value + "</li>";
    html += "</ul>";
});
setTimeout(function () {
    $(".container").append(html);
}, 1500);

试试这个

demo

您已经从data $.each(data.data, function (index, item) {获取了数据addWidget()，无需进行其他迭代。

删除第二个var html = ""; $.each(data.data, function (index, item) { console.log(data.data) html += "<ul>"; html += "<li>" + item.orderNum + "</li>"; html += "<li>" + item.qty + "</li>"; html += "<li>" + item.userName + "</li>"; html += "<li>" + item.value + "</li>"; html += "</ul>"; }); setTimeout(function() { $(".container").append(html); }, 1500);和前面的项目，如'item.ordernum'。看看这个Fiddle：

以下是更新后的代码：

item.data

我们要求您删除的原因是因为ResourceSet不包含任何内容，您可以在数组上应用$ .each，此项也是一个对象，因此您可以直接访问它。

Answer 4

以上答案是正确的。但是你可以使用jquery来构建html元素，而不是通过字符串连接来创建它。

$.each(data.data, function (index, item) {
    var ul = $("<ul/>");
    var li = $("<li/>", { text: item.orderNum });
    ul.append(li);
    ul.append(li.clone().text(item.qty));
    ul.append(li.clone().text(item.userName));
    ul.append(li.clone().text(item.value));
    $(".container").append(ul);
});

Fiddle

Answer 5

我发现了2个错误 1- $.each(item应为orderNum内循环
2-内环item1.orderNum应为var html = ""; $.each(data.data, function (index, item) { html += "<ul>"; console.log(item); $.each(item, function (index1, item1) { html += "<li>" + item1.orderNum + "</li>"; html += "<li>" + item1.qty + "</li>"; html += "<li>" + item1.userName + "</li>"; html += "<li>" + item1.value + "</li>"; }); html += "</ul>"; }); setTimeout(function() { $(".container").html(html); }, 1500);，对于其下的其他项目应为

labels[i].frame.height = self.view.frame.size.height

从json到ul li
