返回数组和子节点 [英] Returning Arrays and ChildNodes

问题描述

我有以下的code：

var actionsAllowed = $(packet).find('actionsAllowed').get();

var actionArray = $(actionsAllowed).each(function () {
    var actionNodes = this.childNodes;
    var actionNumber = actionNodes.length;
    var array = new Array(actionNumber)

    for (var i = 0; i < actionNodes.length; i++) {
        var action = actionNodes[i].nodeName
        array[i] = action
        console.log(action);
    }
    return array;
});

本搜索actionsAllowed包（XML），并将其作为[actionsAllowed]。

This searches the packet (XML) for "actionsAllowed" and returns it as "[actionsAllowed]".

我然后试图创建与每个阵列中列出的操作的阵列

I am then trying to create an array with each of the actions listed in the array.

的本变成actionsAllowed没有[]并允许它在形式的节点列表[ActionOne，ActionTwo，ActionThree]返回的子节点。
然后我得到的节点列表的长度和创建长度的数组。

The "this" becomes "actionsAllowed" without the "[ ]" and that allows it to return the child nodes in the form "NodeList[ActionOne, ActionTwo, ActionThree]". I then get the length of the NodeList and create an array of that length.

然后我遍历节点列表，每个添加到阵列中。

I then iterate over the NodeList and add each to the array.

截至去年底，它返回数组[ActionOne，ActionTwo，ActionThree]，这是伟大的！

By the end, it returns the array as "[ActionOne, ActionTwo, ActionThree]", which is great!

但是 - 这就是问题所在：

BUT - this is the problem:

变量actionArray变为的对象[actionsAllowed]，而非阵列。

任何想法，这是为什么吗？我有一个理论，但我无法修复它=（

Any idea why this is please? I have a theory but I'm unable to fix it =(

感谢您！

推荐答案

$（actionsAllowed）。每个返回迭代的第一要素。你似乎想这样的：

$(actionsAllowed).each returns the first element of the iteration. You seem to want this :

var actionArray = [];
$(actionsAllowed).each(function () {
    var actionNodes = this.childNodes;
    var actionNumber = actionNodes.length;
    var array = new Array(actionNumber)

    for (var i = 0; i < actionNodes.length; i++) {
        var action = actionNodes[i].nodeName
        array[i] = action
        console.log(action);
    }
    actionArray.push(array);
});    

编辑：如果你想要的是一个很大的数组，而不是数组的数组，将其更改为

EDIT : If what you want is a big array instead of an array of arrays, change it to

var actionArray = [];
$(actionsAllowed).each(function () {
    var actionNodes = this.childNodes;
    for (var i = 0; i < actionNodes.length; i++) {
        var action = actionNodes[i].nodeName
        actionArray.push(action);
        console.log(action);
    }
});
