官方搜索組件 searchbar。（這里我只拿取用到的input框）

 <input type="text" class="weui-search-bar__input" placeholder="{{newSearch}}" value="{{value}}" focus="{{focus}}" bindblur="inputBlur" bindfocus="inputFocus" bindinput="inputChange" />
            

searchbar.js(這里我也就拿取一部分事件)

methods: {
        inputFocus: function inputFocus(e) {
            this.triggerEvent('focus', e.detail);
        },
        inputBlur: function inputBlur(e) {
            this.setData({
                focus: false
            });
            this.triggerEvent('blur', e.detail);
        },
   }

如下父組件使用
index.wxml

<mp-searchbar bind:clear="clearInput" bind:blur="inputBlur" bind:focus="inputFocus" bind:input="inputChange"></mp-searchbar>
	

index.js

  /**
   * 搜索框
   */
  inputBlur:function(e){
    console.log(e.detail); 
  },
  inputFocus:function(e){
    console.log(e.detail); 
  },
  inputChange:function(e){
    this.setData({
      value:e.detail.value
    })
    console.log(e.detail); 
  },
  clearInput:function(){
  },
