如何使用jQuery创建哈希对象/数组？ [英] How to create Hash object/array using jquery?

问题描述

我知道Javascript原型框架中有一个Hash（）对象，但是Jquery中有这样的东西吗？

I know there is a Hash() object in the Javascript prototype framework, but is there anything in Jquery like this?

正如我想坚持一个javascript框架，而不是混合Prototype Frame工作和JQuery框架并同时使用，因为我担心会有冲突并产生副作用。

As I would like to stick with one javascript framework, rather than mixing the Prototype Frame work and the JQuery framework and use at the same time, as I worry there will be conflict and create side-effects.

所以我的问题是：如何使用jquery创建Hash对象/数组？

So my question is: how to create Hash object/array using jquery?

以下是我的函数：

Here is my function:

/* prototype framework, I want to change this to jQuery! */
var starSaves = new Hash();

function myHover(id, pos)
{
    var starStrip = $('star_strip_' + id);    
    if (starSaves.keys().indexOf(id) == -1)
    {
        var starSave = new Array();
        var imgs = starStrip.select("img")
        alert(imgs);
        for (var i = 0; i < imgs.length; i++)
        {
            starSave[starSave.length] = imgs[i].src;
            if (i < pos)
                imgs[i].src = "/images/star_1.gif";
            else
                imgs[i].src = "/images/star_0.gif";

        }
        starSaves.set(id, starSave);
    }
}

推荐答案

一个独立的哈希表实现，名为 jshashtable （完全公开：我写了它）。使用它，你的代码将是：

There's a standalone hash table implementation called jshashtable (full disclosure: I wrote it). Using it, your code would be:

var starSaves = new Hashtable();

function myHover(id, pos)
{
    var starStrip = $('star_strip_' + id);
    if (!starSaves.containsKey(id))
    {
        var starSave = new Array();
        var imgs = starStrip.select("img")
        alert(imgs);
        for (var i = 0; i < imgs.length; i++)
        {
            starSave[starSave.length] = imgs[i].src;
            if (i < pos)
                imgs[i].src = "/images/star_1.gif";
            else
                imgs[i].src = "/images/star_0.gif";

        }
        starSaves.put(id, starSave);
    }
}
