weex 的 input 組件中的blur和focus函數(shù)無(wú)法調(diào)用？

問(wèn)題

無(wú)法調(diào)用weex的input組件中的blur和focus 函數(shù)。 但我調(diào)用input的blur(focus)函數(shù)時(shí)，鍵盤并沒(méi)有被收起，此時(shí)查看Android studio 打印的日志提示一下錯(cuò)誤

下面是我的.vue 文件內(nèi)容

<template>
  <div @click="click" class="bounds">
      <input ref = "inputMessage" class= "input" type="text" value="測(cè)試數(shù)據(jù)"></input>
  </div>
</template>

<style scoped>

.input {
    top: 100;
    width: 600;
    left: 50;
    height: 100;
    background-color: red
}
.bounds {
    position: absolute;
    top: 0;
    left: 0;
    width: 750;
    background-color: green
}
</style>


<script>
export default {
    methods: {
        click: function(e) {
            this.$refs.inputMessage.blur()
            // console.log('this.refs', this.refs)
        }
    }
}
