我有这样的HTML代码:

<div id="test">
    <div id="test1">
        <div id="test2">
            test
        </div>
    </div>
</div>


我想获取元素“ test”的所有子元素,因此我做了一个递归函数:

function getObjectChildren(elem) {
    var elemChildren = elem.childNodes;
    var result = [];
    result.push.apply(elemChildren);
    for (k = 0; k < elemChildren.length; k++) {
        if (elemChildren[k].childNodes.length > 0) {
            result.push.apply(getObjectChildren(elemChildren[k]));
        }
    }
    return result;
}

var a = getObjectChildren(document.getElementById("test");


事实是,此递归函数进入无限循环。有谁知道为什么会这样,我该如何解决呢?

最佳答案

我解决了我的问题:

function getObjectChildren(elem) {
    var elemChildren = elem.childNodes;
    var result = [];
    for (var k = 0; k < elemChildren.length; k++) {
        result.push(elemChildren[k]);
        if (elemChildren[k].childNodes.length > 0) {
            var tmp = getObjectChildren(elemChildren[k]);
            for (var i = 0; i < tmp.length; i++) {
                result.push(tmp[i]);
            }
        }
    }
    return result;
}
