How to operate vue.js element-ui tree tree control to change iview

This time I will show you how to change the vue.js element-ui tree tree control to iview, and how to change the vue.js element-ui tree tree control to iview. What are the precautions?What are the following? This is a practical case, let’s take a look at it.

Implementation principle

Modified the element-ui source code, extracted the tree module in the source code

Then modified the checkbox and other components that come with element as Checkbox of iview, and compatible method

Finally modified the element style, changed it to iview style, and added some styles myself

The new tree component can be said to be the logic of element and the style of iview

<template>
 <p
  @click.stop="handleClick"
  v-show="node.visible">
  <p class="chu-tree-nodecontent"
   :style="{ &#39;padding-left&#39;: (node.level - 1) * tree.indent + &#39;px&#39; }">
   <span :class="arrowClasses" @click.stop="handleExpandIconClick">
     <Icon v-if="!node.isLeaf" type="arrow-right-b"></Icon>
   </span>
   <Checkbox
    v-if="showCheckbox"
    :value="node.checked"
    :indeterminate="node.indeterminate"
    :disabled="!!node.disabled"
    @click.native.stop
    @on-change="handleCheckChange"></Checkbox>
   <span
    v-if="node.loading"
    class="ivu-load-loop">
   </span>
   <node-content :node="node"></node-content>
  </p>
  <collapse-transition>
   <p
    v-show="expanded">
    <el-tree-node
     :render-content="renderContent"
     v-for="child in node.childNodes"
     :key="getNodeKey(child)"
     :node="child"
     @node-expand="handleChildNodeExpand">
    </el-tree-node>
   </p>
  </collapse-transition>
 </p>
</template>

Modify handleCheckChange because the logic of iview's checkbox component is different and the return of the function is different. It needs to be compatible with

handleCheckChange(ev) {
    this.node.setChecked(ev, !this.tree.checkStrictly);
   },

The project structure after extraction is completed, and encapsulated into an npm plug-in

How to use

Must install iview

All styles are replaced with ivew

The functions are all in accordance with element- The ui is the same as before

npm i chu-tree-iview

import chuView from 'chu-tree-iview'
Vue.use(chuView)
<chu-tree></chu-tree>

The usage documentation is exactly the same as element-ui
