在点击页面上一个按钮时让input获取光标

已解决

<view class="searchButtonList">  
    <image class="searchIcon" src="../../static/images/icon/ic-sousuo.png" mode=""></image>  
    <input class="searchInput" placeholder="搜索" v-model="searchValue" auto-focus :focus="searchFocus" @blur="searchBlur()" @input="searchDelShow"/>  
    <image class="delIcon" v-if="searchDelButTag" src="../../static/images/icon/ic-del.png" @click="searchDelBut()"></image>  
</view>

/是否显示搜索叉叉  
searchDelShow(event){  
    console.log(event.detail.value.length)  
    if(event.detail.value.length > 0){  
        this.searchDelButTag = true;  
    }else{  
        this.searchDelButTag = false;  
    }  
},  
//搜索框光标离开事件  
searchBlur(){  
    this.searchFocus = false;  
},  
//搜索框×按钮的点击事件  
searchDelBut(){  
    // console.log('搜索框×按钮的点击事件');  
    this.searchValue = "";  
    var _this = this;  
    setTimeout(function(){  
        _this.searchFocus = true;  
    },500)  
},
