向JSON添加一行

Question

我想在用户点击链接时向我的JSON添加一个新行.这是我的javascript:它没有错误,但我没有在我的警报中获得更新的JSON.

$(document).ready( function(){

people = {
    "COLUMNS":["NAME","AGE"],
    "DATA":[
    ["Jon","16"],
    ["Jerry","23"]
    ]
} 

members = people.DATA;
var nc = "<table border=1 width=500><tr><td>name</td><td>age</td><td></td></tr>";

for(var i=0;i<members.length;i++)
{
    nc+= '<tr><td>' + members[i][0] + '</td>';
    nc+= '<td>' + members[i][1] + '</td>';
    nc+= '<td><a href="" class="addlink">add a new person</a></td></tr>';
}

nc += "</table>";

$("#result").html(nc);

$(".addlink").click( function(){ 

    // add another row to our JSON
    people.DATA['NAME'] = "new";
    people.DATA['AGE'] = "99";

    alert(people.DATA);
    return false;

});
});

那不是JSON,它是一个Javascript对象.

要在数组中添加另一个项,您需要创建一个数组并添加它,因为它是一个数组数组:

people.DATA.push(["new", "99"]);
