我要设置滚动高度。因此滚动不超过页脚或显示的时间表为5个数据

我该怎么办？

Answer 1

是的，可以将滚动时间嵌套的高度设置为datepicker。

默认情况下，对话框带有必须禁用的滚动首先，我们可以将滚动条分别添加到日期选择器或时间范围盒

在下面的代码中，我将datepicker页脚按钮作为单独的flex进行了移动，并仅向时间添加了滚动，以便它可以根据时隙的数量而增长

        <v-dialog
            :return-value.sync="date"
            v-model="modal"

             content-class="dialog-class"
            ref="dialog"
