遍历jQuery JSON Object数组 [英] traversing jQuery JSON Object array

问题描述

我尝试使用getJson访问一个Object数组，我尝试过很多东西但是我一直在回复'undefined'或[Object，object]。

I am try access an Object array using getJson, I've tried many things but I keep getting an 'undefined' or [Object, object] returned.

$.getJSON( "js/test.json", function( data ) {
    var items = new Array();
    $.each( data, function( key, val ) {
        items.push( "<li id='" + key + "'>" + val.entries.title + "</li>" );
    });

    $( "<ul/>", {
        "class": "my-new-list",
        html: items.join( "" )
    }).appendTo( "body" );
});

这是JSON，我试图获得每个'条目'的'标题'。

Here is the JSON, I am trying to get the 'title' of each 'entries'.

{
"$xmlns": {
    "pl1": "url"
},
"startIndex": 1,
"author": "MJS",
"entries": [
    {
        "title": "This is target",
        "m$ct": [
            {
                "m$name": "name"
            }
        ],
        "m$rt": "pd",
        "m$content": [
            {
                "plfile$width": 640
            },
            {
                "plfile$width": 960
            }
        ],
        "plm$c": [],
        "link": ""
    },
    {
        "title": "title2",
        "m$ct": [
            {
                "m$name": "name"
            }
        ],
        "m$rt": "pd",
        "m$content": [
            {
                "plfile$width": 640
            },
            {
                "plfile$width": 960
            }
        ],
        "plm$c": [],
        "link": ""
    }
]
}

推荐答案

$.each( data, function( key, val ) {
    items.push( "<li id='" + key + "'>" + val.entries.title + "</li>" );
});

应改为：

$.each( data.entries, function( key, entry ) {
    items.push( "<li id='" + key + "'>" + entry.title + "</li>" );
});
