Vue結(jié)合原生js實現(xiàn)自定義組件自動生成示例

更新時間：2017年01月21日 15:30:37 作者：frankly-26

這篇文章主要介紹了Vue結(jié)合原生js實現(xiàn)自定義組件自動生成示例,小編覺得挺不錯的，現(xiàn)在分享給大家，也給大家做個參考。一起跟隨小編過來看看吧

就目前三大前端主流數(shù)據(jù)驅(qū)動框架（vue,ng,react）而言，均具有創(chuàng)建自定義組件的api，但都是必須先做到事先寫好掛載點，這個掛載點可以是原有靜態(tài)元素標(biāo)簽也可以是自定義模板；對于多種組件通過同一數(shù)據(jù)流生成的，如果事先在頁面上寫好掛載點(mounted)，然后通過dom操作去動態(tài)添加，會遇到類似這樣一條錯誤提示信息：Failed to execute 'appendChild' on 'Node': parameter 1 is not of type 'Node'.(…)。這又是為何呢，下一步該怎么辦？

原因是任何dom操作的對象必須是符合W3C標(biāo)準(zhǔn)的元素，除非如下所述的，改寫生成html元素對象的原型（HTMLElement.prototype）并注冊自定義元素，從而實現(xiàn)動態(tài)生成自定義組件的效果。

不過，大家都明白使用數(shù)據(jù)驅(qū)動框架的初衷就是盡可能避免dom操作，而如下代碼中還是有一些dom操作的，就目前認(rèn)知水平而言，感覺這些必要的dom操作還是避免不了的。其它不多說了，直接看代碼。。。

  (function () {

  })();
  function AnalyJson(data) {
    if ('id' in data) {
      arguments.callee(data.values);
    } else {
      if ('name' in data) {
        htmlname = data.name;
        CreateInputViewer(data.name);
        arguments.callee(data.values);
      } else {
        if ('type' in data) {
          CreateInputViewer(data);
        } else {
          for (var p in data) {
            CreateInputViewer(data[p]);
          }
        }
      }
    }
  }
  function CreateInputViewer(data) {
    switch (data.type) {
      case 'text': {
        fh_C(data, 'c-input-text' + '-' + data.key, 'fhInputText', textTpl);
        break;
      }
      case 'textarea': {

      case 'radio': {
        fh_C(data, 'c-input-radio' + '-' + data.key, 'fhInputTextarea', radioTpl);
        break;
      }
      case 'checkbox': {

    }
  }
  function fh_C(d, c, cn, tpl) {
    console.log(d);
    Vue.component(c, {
      template: tpl,
//       props:['key','keyname','values','value'],
      data: function () {
        return d
      }
    });
    new Vue({
      el: '.mui-content',
      components: {
        cn: cn
      },
    });
    var MyElementProto = Object.create(HTMLElement.prototype);
    MyElementProto.createdCallback = function () {
      this.innerHTML = tpl
    };
    var MyComponent = document.registerElement(c, {prototype: MyElementProto});
    document.querySelector('.mui-content').appendChild(new MyComponent());
  }
</script>
</html>

為了保持代碼的可維護性及易讀性，我將模板部分單獨放在fuhao-components.js的文件里邊，如下所示：

var textTpl='';
<div class="mui-content-padded">
  <input :type="type" :name="key" :placeholder="keyname" >
</div>
  
var textareaTpl= '';
<div class="mui-content-padded ">
  <textarea rows="5" :placeholder="keyname"> 
  </textarea>
</div>
  
var radioTpl= '';
<form class="mui-input-group mui-content-padded">
    <div class="mui-input-row mui-radio mui-left"v-for="value in values">
      <label>{{value.key}}</label>
      <input :name="key" :type="type" :value="key">
    </div>
</form>
var checkboxTpl= '';
<form class="mui-input-group mui-content-padded">
    <div class="mui-input-row mui-checkbox mui-left"v-for="value in values">
      <label>{{value.key}}</label>
      <input :name="key" :type="type" :value="key">
    </div>
</form>
var selectTpl= '';
  <div class="mui-content-padded">
  <h5 class="mui-content-padded" v-text="keyname"></h5>
    <select class="mui-btn mui-btn-block " :name="key">
      <option value="key" v-text="value.key" v-for="value in values">{{value.key}}</option>
    </select>
  </div>

var photoTpl= '';
<div class="mui-content-padded">
  <span v-text="keyname"></span>
  <button :name="key" onclick="takePhoto(this.name)" class="mui-btn mui-btn-primary">拍照</button> 
  <img :id="key" height="70" width="100" class="img-rounded">
</div>
  
var gpsTpl='';
<div class="mui-content col-xs-12">
  <button class="mui-btn mui-btn-primary" :id="key" onclick="takeLocation(this.id)">
  獲取定位
  </button>
</div>
  
var defaultTpl= '';
<div class="mui-content-padded " v-if="key">
  <ul class="mui-table-view">
    <li class="mui-table-view-cell mui-media">
      <span class="fuhaoKey" v-text="key"></span>
      <span class="fuhaoValue" v-text="value"></span>
    </li>
  </ul >
</div>

最終渲染效果如下：
