`<template>
<view class="back_header">

    <icon @click="toBack"></icon>

</view>
</template>

<script>
export default {
name: "backHeader",

props: {
    titleStr: String
},

data () {

return {
}

},
methods: {

toBack() {
        this.$mRouter.back();
}

父:
<back-header :titleStr="titleStr" :backHeadShow="backHeadShow" v-if="backHeadShow"></back-header>
