Jq自定义的方法绑定树结构

1.先上效果图  （借鉴博客）

2.这边不做样式的只做结构

function toTreeData(data) {
        var pos = {};
        var tree = [];
        var i = 0;
        while (data.length != 0) {
            if (data[i].pid == 0) {
                tree.push({
                    id: data[i].id,
                    text: data[i].text,
                    children: []
                });
                pos[data[i].id] = [tree.length - 1];
                data.splice(i, 1);
                i--;
            } else {
                var posArr = pos[data[i].pid];
                if (posArr != undefined) {

                    var obj = tree[posArr[0]];
                    for (var j = 1; j < posArr.length; j++) {
                        obj = obj.children[posArr[j]];
                    }

                    obj.children.push({
                        id: data[i].id,
                        text: data[i].text,
                        children: []
                    });
                    pos[data[i].id] = posArr.concat([obj.children.length - 1]);
                    data.splice(i, 1);
                    i--;
                }
            }
            i++;
            if (i > data.length - 1) {
                i = 0;
            }
        }
        return tree;
    }
