如何使用jQuery搜索JSON树

var json = {    "people": {        "person": [{ "name": "Peter", "age": 43, "sex": "male"},        { "name": "Zara", "age": 65, "sex": "female"}]    }};$.each(json.people.person, function(i, v) {    if (v.name == "Peter") {        alert(v.age);        return;    }});

根据此答案，您可以使用类似：

$(function() {    var json = {        "people": { "person": [{     "name": "Peter",     "age": 43,     "sex": "male"}, {     "name": "Zara",     "age": 65,     "sex": "female"}]        }    };    $.each(json.people.person, function(i, v) {        if (v.name.search(new RegExp(/peter/i)) != -1) { alert(v.age); return;        }    });});
