Vue结合原生js实现自定义组件自动生成示例有哪些?

就目前三大前端主流数据驱动框架(vue,ng,react)而言,均具有创建自定义组件的api,但都是必须先做到事先写好挂载点,这个挂载点可以是原有静态元素标签也可以是自定义模板;对于多种组件通过同一数据流生成的,如果事先在页面上写好挂载点(mounted),然后通过dom操作去动态添加,会遇到类似这样一条错误提示信息:Failed to execute 'appendChild' on 'Node': parameter 1 is not of type 'Node'.(…)。这又是为何呢,下一步该怎么办?

原因是任何dom操作的对象必须是符合W3C标准的元素,除非如下所述的,改写生成html元素对象的原型(HTMLElement.prototype)并注册自定义元素,从而实现动态生成自定义组件的效果。

不过,大家都明白使用数据驱动框架的初衷就是尽可能避免dom操作,而如下代码中还是有一些dom操作的,就目前认知水平而言,感觉这些必要的dom操作还是避免不了的。其它不多说了,直接看代码。。。

  AnalyJson(jsonData);
 })();
 function AnalyJson(data) {
  if ('id' in data) {
   arguments.callee(data.values);
  } else {
   if ('name' in data) {
    htmlname = data.name;
    CreateInputViewer(data.name);

 }
 function CreateInputViewer(data) {
  switch (data.type) {
   case 'text': {
    fh_C(data, 'c-input-text' + '-' + data.key, 'fhInputText', textTpl);
    break;
   }
   case 'textarea': {
    fh_C(data, 'c-textarea' + '-' + data.key, 'fhInputTextarea', textareaTpl);

  }
 }
 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>

为了保持代码的可维护性及易读性,我将模板部分单独放在fuhao-components.js的文件里边,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)">
 获取定位
 </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>

鉴于vue结合dom操作动态生成自定义组件,控制台会报一定的错误这一点bug还在努力修复中,可能需要更加深入地了解vue数据绑定及传递机制与js动态注册自定义组件的深入领会,继续努力中。。。
