拖延了三四天才把這個樹狀圖搞出來.......果然拖延症需要治療（。
目的：多級樹狀圖
需求：
- 點擊某一級成員可將他的下一級顯示；
- 多級顯示；
- 可左右拖動；
- 結構以ul+li+a爲主。
嘗試1：浮動佈局

如果采取浮動的話，將li設爲float:left即可，效果如下：
但是會出現兩個問題：
- 整個樹狀圖無法居中
- 多級顯示后，當前寬度超出固定寬度或自適應時，浮動佈局無法强制拓寬寬度，會出現下面的情況：
原本是用jQuery，每次點擊成員展開下級后給寬度增加80px，并且給當前div一個最小寬度，這樣自適應或是寬度超出時，樹狀圖將會自動拓展。但是還是無法解決居中問題。
嘗試2：Flex
將浮動佈局換做Flex彈性佈局

jQuery
/**
* 思路：
* 1、在第一次打開后就將所有數據載入，但只顯示兩級，其他用display:none隱藏;
* 2、在點擊成員時，做出判斷：(1)該成員是否有下級(2)下級是否展開;
* 3、若成員無下級，則彈出提示；若下級已經展開，則收起。
*/
$(function(){
$("#tree a").click(function(){
var _this = $(this);
if( _this.hasClass("active") ){
_this.removeClass("active");
}else if(!_this.siblings("ul").length){
alert("该会员没有下级");
}else{
$(this).addClass("active");
$(this).parent("li").css("display","inline");
}
});
});
效果如下：
360瀏覽器 極速模式，火狐瀏覽器，UC瀏覽器
儅寬度縮小后出現滾動條
但是這樣有個比較坑的是：
寬度縮小后，第一層移位
待解決......
