带有占位符文本的文本框，逐字逐句消失 [英] text box with placeholder text that dissapears character by character

问题描述

我正在寻找一种方法来构建一个带有占位符文本的文本框，用于日期字段。占位符文本将是xx / xx / xxxx并逐个字符消失，并在用户键入时留下斜杠。我遇到了以下两个问题，它们似乎解决了使文本一下子消失的问题。

The placeholder text would be xx/xx/xxxx and disappear character by character leaving the slashes in place as the user types. I came across the following two questions which seem to solve the problem of making the text disappear all at once.
