利用localStorage让首页弹框只在页面出现一次

    
    <div v-if="isShow">
        
        <div class="opacity-back">div>
        
        <div class="model-box">
            <div class="model-header">
                <span class="close" @click="close">×span>
            div>
            <div class="model-body">
                <a :href="plaqueObj.webClickUrl" target="_blank"><img :src="plaqueObj.picUrl" alt="">a>
            div>
        div>
    div>
