我需要为关键字和标签动态添加值 – JavaH 2012-08-01 12:49:29

您如何准确确定要将值添加到哪个关键字数组？ – AdityaParab 2012-08-01 12:50:24

我在关键字和标签的数据库中有一些价值。是否可以添加值？ – JavaH 2012-08-01 12:53:09

常规方式，

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

和

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

让我们知道你如何确定index值，这样我们就可以以更具体的方式帮助你:)

谢谢你的回复...索引从零开始，链接[index] .keywords [links [index] .keywords.length] =“你的新值”;我不明白这一行 – JavaH 2012-08-01 12:57:19

它就像'links [index] .keywords'将选择关键字数组...'links [index] .keywords [links [index]。关键字.length]'会给你选定数组的长度。如果该关键字数组在最后添加新元素... – AdityaParab 2012-08-02 07:41:46

添加新标签

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

添加关键字，则需要通过链接阵列

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

上面的代码正在考虑要添加到“空标签”的关键字进行迭代标签

套装将键和标签作为变量，然后将键添加到阵列中的标签索引中：

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

links[label] = keys; 

alert(links["Create user"]);

该提醒：create,add,make,insert,user
