Javascript 使用jQuery进行树遍历

这只是为较小的树生成json，我希望解决方案是通用的。这个解决方案的另一个问题是，它多次重复相同的节点。请帮帮我，我被困在我的项目里了。

像这样的事情

function processOneLi(node) {       
        var aNode = node.children("a:first");
        var retVal = {
            "link": aNode.attr("href"),
            "title": aNode.text()
        };
        node.find("> .children > li").each(function() {
            if (!retVal.hasOwnProperty("nodes")) {
                retVal.nodes = [];
            }
            retVal.nodes.push(processOneLi($(this)));
        });
        return retVal;
    }

 function json_output()
    {
        $("#org > li").each(function() {
            out.push(processOneLi($(this)));
        });

        console.log("got the following JSON from your HTML:", JSON.stringify(out));
    }

把它当作

function generateTree($node, result) {
    result = result || {'nodes' : []};
    $node.children('li').each(function(){
        var $this = $(this);
        var anch = $this.children('a').get(0);
        var elem = {
            "link": anch.href,
            "title": anch.innerHTML,
            "nodes" : []
        };

        if($this.has('ul'))
            generateTree($this.children('ul'), elem);
        result.nodes.push(elem);
    });
    return result.nodes; //or just return result.nodes[0] to access the root as object. But the existing one will be generic in case you are setting up for a class selector for multiple ul's as root.
}

测试指南：嘿，我非常喜欢这个。我在帮你拉小提琴：）谢谢你，男人-看起来很完美-我会在动态列表生成中试用。@PSL我在这里也需要你的帮助吗？如果可能的话，可能吗？

function generateTree($node, result) {
    result = result || {'nodes' : []};
    $node.children('li').each(function(){
        var $this = $(this);
        var anch = $this.children('a').get(0);
        var elem = {
            "link": anch.href,
            "title": anch.innerHTML,
            "nodes" : []
        };

        if($this.has('ul'))
            generateTree($this.children('ul'), elem);
        result.nodes.push(elem);
    });
    return result.nodes; //or just return result.nodes[0] to access the root as object. But the existing one will be generic in case you are setting up for a class selector for multiple ul's as root.
}

var resTree = generateTree($("#org"));
console.log(JSON.stringify(resTree));
