将JSON插入HTML

Question

我们说我有一个类似下面的JSON文件。如何将特定值（例如0.69）插入HTML页面？

{
    "species":1,

    "animal":[
        {"day": 1,"weight": [0.69,1,2,3],"amounteaten": [22,16,15,14],"emergencies": [0,0,0,0]},
        {"day": 2,"weight": [0.5,1,3,4],"amounteaten": [22,17,15,14],"emergencies": [0,0,1,0]}

    ]
}

Answer 1

你在找这样的东西吗？

<div id="foo"></div>

$.getJSON('intro.json', function(obj) {
    document.getElementById("foo").textContent = obj.animal[0].weight[0];
});
