vue3 設定el-dialog height超過捲軸

方法一：

<style scoped>
 ::v-deep .el-dialog .el-dialog-body{
    height: 500px;
    overflow-y: auto;
 }
</style>

如果要設定動態的高度話，則要在setup裡面設定

<script >
  export default defineComponent({
    setup:{
        const cssContent=ref({height:'100%',overflowY:''})
        const init=()=>{
            cssContent.value.height='500px'
            cssContent.value.overflowY='auto'
        }
        init()
        return {
            cssContent,
            init
        }
    }
  })
</script>
<style scoped>
 ::v-deep .el-dialog .el-dialog-body{
    height: v-bind('cssContent.height');
    overflow-y: v-bind('cssContent.overflowY');
 }
</style>
