问题描述

我正在尝试使用 JavaScript 正则表达式 /[\u0600-\u06FF]/ 按照 这篇文章.我只想接受阿拉伯字母字符和空格.

I am trying to implement "alpha" validation on Arabic alphabet characters input, using the JavaScript regex /[\u0600-\u06FF]/ as instructed in this post. I want to accept only Arabic alphabet characters and spaces.

现在的问题是它给出了以下结果:

Now the problem is it gives the following result:

r = /[\u0600-\u06FF]/

r.test("abcd")      // false - correct
r.test("@#$%^")     // false - correct
r.test("س")         // true  - correct
r.test("abcd$$#5س") // true  - should be false
r.test("abcdس")     // true  - should be false

如果给出了单个匹配字符,那么它将整个输入分类为可接受的,即使输入的其余部分充满了不可接受的字符.我应该改用什么正则表达式?

If a single matching character is given, then it is classifying the whole input as acceptable, even if the rest of the input is full of unacceptable chars. What regex should I be using instead?

推荐答案

需要在正则表达式中添加^$锚点,以及一个+ 允许多个字符.

You need to add ^ and $ anchors to the regular expression, as well as a + to allow multiple characters.

试试这个:

/^[\u0600-\u06FF]+$/

我不确定您提到的阿拉伯空格"是否包含在那里的字符范围内,但是如果您想在字符串中允许空格,那么只需在其中添加一个 \s[] 括号.

I'm not sure if "Arabic spaces" that you mentioned are included in the character range there, but if you want to allow white space in the string then just add a \s inside the [] brackets.
