问题描述

我正在制作一个简单的网站。对于第一个变量提示,在'delivery'功能下,我希望用户输入一个名称。我已经设置了它,所以他们不仅可以输入数字,但是当用户输入数字和字母的组合时,它仍然接受它,并继续该程序。



我想只接受信件。



我该怎么做?



谢谢!



Hi, I am making a simple website. For the first variable prompt, under the 'delivery' function, I would like the user to input a name. I've already set it up, so they cannot only enter numbers, but when the user enters a combination of number and letters, it still accepts it, and continues with the program.

I would like to to only accept letters.

How can I do this?

Thanks!
