rTree 树形控件一级菜单没有复选框，子菜单有复选框，如何实现？_阿 尭的博客-CSDN博客

接上一篇博客，继续深入功能，如何只选中叶子节点而不选中父节点。

1.在节点被点击时的回调，node-click中，返回的对象中加上一个属性leaf。

 父节点的leaf为false，子节点为true。

      handleNodeClick(node) {
        this.selectedDep = {
          name:node.name,
          id:node.nodeId,
          Order:node.Order,
          leaf:node.leaf==false?false:true
        }
        console.log('selectedDep',this.selectedDep);
      },

 <span slot="footer" class="dialog-footer">
          <el-button size="small" @click="closeInputSelectedDepDialog(0)">取 消</el-button>
          <el-button class="my-e-button"  size="small" @click="closeInputSelectedDepDialog(1)">确定选择</el-button>
     </span>

2.在点击确定的时候，判断一下node.leaf为true还是false，若为false则不能返回出去，传递给子组件。

 3.在子组件中收到父组件传递的值为对象，循环遍历拿到对象的属性，进行绑定值渲染在页面上。

 emitSubmit(selectedDepArr,selectedDep) {

      if (selectedDepArr.length) {
        this.TechnicalTitleArr = selectedDepArr;
        console.log(" this.TechnicalTitleArr", this.TechnicalTitleArr);
        this.names = this.TechnicalTitleArr.map((obj) => obj.name);
        this.ruleForm.rmhgwyzj = this.names.join(" ");
      } else {
        console.log('selectedDepArr',selectedDepArr);
        if (selectedDepArr.name) {
          this.ruleForm.rmhgwyzj = selectedDepArr.name;
        }
      }
       this.isShow = false;
    },

 <span class="span">任免后公务员职级:</span>
      <el-form-item prop="rmhgwyzj" label-width="130px" placeholder="请选择">
         <span @click="isShow = true" class="jiaInput" style="background-color: white;">
          <span :class="{ 'gray-text': ruleForm.rmhgwyzj !== 1, 'black-text': ruleForm.rmhgwyzj }">
                  {{ ruleForm.rmhgwyzj ? ruleForm.rmhgwyzj : '请选择' }}
             </span>
            </span>
      </el-form-item>
