有人能告诉我如何循环这个JSON并将其附加到html中吗。
我试过这样的东西?
$(function() {
$.getJSON("http://crossdomain.com/path/to/abovejsonfile", function(data) {
$.each(data.item[0], function(index, it){
var d = $('<div>'+ it.title +'</div>');
alert(d); //doesn't work
});
});
$(函数(){
$.getJSON(“http://crossdomain.com/path/to/abovejsonfile,函数(数据){
$.each(数据项[0],函数(索引,it){
变量d=$(''+it.title+'');
警报(d);//不起作用
});
});
我的呈现页面应该是这样的?
<div class="container">
<div class="node" id="n1">
<div class="title">Title should come here</div>
<a class="link">Link</a>
<div class='d'>Date should be here</div>
</div>
<div class="node" id="n2">
<div class="title">Title should come here</div>
<a class="link">Link</a>
<div class='d'>Date should be here</div>
</div>
<div class="node" id="n3">
<div class="title">Title should come here</div>
<a class="link">Link</a>
<div class='d'>Date should be here</div>
</div>
......
</div>
标题应该在这里
链接
日期应该在这里

非常感谢您的帮助
Mike您需要迭代
数据[“内容”]
数组的元素:
$.each(data["content"], function(index, it){
您正确地使用了each方法,但是在each中,您告诉他使用索引0迭代该项
$.each(data.item[0], ....
现在jQuery也可以迭代对象了(http://docs.jquery.com/Utilities/jQuery.each )但那不是你现在想要的
如果你想迭代一个数组,你必须通过一个数组(就像其他任何支持each/foreach的语言一样)
所以只要使用
$.each(data.item[0], ....
你的代码运行良好
如何将带有ID的链接/div附加到html:
$('<p>Hello World</p>').appendTo('body');
$(“helloworld”).appendTo('body');
省去使用循环手动执行此操作的麻烦,并使用客户端模板引擎,如或
下面是您使用json2html的目的

我如何将带有ID的链接/div附加到HTMLH中,这不会有帮助。您能帮助进行json解析吗?在这种情况下,我收到[object object]警报这是正确的行为。您创建DOM元素(div)这是一个对象。请尝试传递it.title
以提醒有更多详细的输出。或者使用浏览器的console.log
和JavaScript控制台检查创建的div的内容。
