@keyname="selectedUserObj"

</zxhtree>
js就是去填补上述的数据，比如deptData、sysUserRole这些。至于这些属性代表什么意思我们先不着急看。先上个效果图。
那么我们的zxhtree控件是在哪里注册的呢，这里被我们抽离在component.js里。
Vue.component('zxhtree', {});继续在zxhtree里看除绑定的节点是
template: '#tree-template'。tree-template的模板是在component.html中写好的
<script type="text/x-template" id="tree-template">
<div>
<tree-item
class="item"
:treekey="treekey"
v-for="(model, index) in model"
:treename="treename"
:treechildren="treechildren"
:model="model"
:ids="ids"
:names="names"
@keyname="selectedObj"
@data="synchdata"
>
</tree-item>
</div>
</script>而在tree-template用到的tree-item控件才是真正的tree控件。这里是为了将树形包裹起来，所以才包裹了一层模板。
tree-item对应的模板代码是
<script type="text/x-template" id="item-template">
<ul class="ztree">
<li class="level0" @blur="blur" @focus="focus" tabindex="0" hidefocus="true" treenode="">
<input type="checkbox" :disabled="model.disabled" :ref="model[treename]" :checked="checkStatus" @click="selectedObj"/>
<span title="" @click="toggle" :class="openStatus" treenode_switch=""></span>
<a :class="selectClass" treenode_a="" onclick="" target="_blank" style="" :title="model[treename]">
<span title="" treenode_ico="" class="button ico_open" style=""></span>
<span @dblclick="toggle" class="node_name">{{model[treename]}}</span>
</a>
<tree-item
class="item"
v-show="open"
v-for="(model, index) in model[treechildren]"
:key="index"
:model="model"
:treekey="treekey"
:treename="treename"
:vistreekey="vistreekey"
:vistreename="vistreename"
:treechildren="treechildren"
ref="child"
@keyname="keyname"
>
</tree-item>
</li>
</ul>
</script>可以很明显的看到这里我们使用了递归进行展示树形结构。因为树形结构你无法确定层级。所以在里面又使用了针对子节点的展示tree-item.
