Answer 1

添加新标签

newLabel = { "keywords":[], "label":"Empty Label" };
links.push(newLabel);

要添加到关键字，您需要遍历链接数组

$(links).each(function(){ if(this["label"] = "Empty Label") { this["keywords"].push("newKeyword") } });

以上代码正在考虑您要添加到“空标签”标签的关键字

Answer 2

一般方法是（前提是您知道关键字数组的索引），

links[index].keywords[links[index].keywords.length] = "your new value";

和

links[index].label = "your new label value";

告诉我们如何确定index值，以便我们以更具体的方式为您提供帮助：）

Answer 3

将键和标签设置为变量，然后将键添加到数组中标签的索引：

var links = new Array();
var keys = ['create', 'add', 'make', 'insert', 'user'];
var label = "Create user";

links[label] = keys;

alert(links["Create user"]);

提醒：create,add,make,insert,user

将数组中的动态变量添加到jQuery函数中
