我需要用什么正则表达式来检查一些非拉丁字符？ [英] What regular expression do I need to check for some non-latin characters?

问题描述

如果字段是拉丁字符，我正在检查字段。

I am checking a field if it is Latin Characters or not.

var foreignCharacters = $("#foreign_characters").val();
var rlatins = /[\u0000-\u007f]/;

if (rlatins.test(foreignCharacters)) {
  alert("This is Latin Characters");
} else {
  alert("This is non-latin Characters");    
}

这很有效，但我想改变它，所以当我输入任何非拉丁字符，例如中文字符，以及空格（在我目前使用的范围内），它仍然会说它是非拉丁字符。

This works well, but I would like to change it so when I enter any non-latin characters, such as chinese characters, along with a space(which is within that range I am using currently) it will still say it is non-latin characters.

如何更改我必须执行的正则表达式？

How can I change the regular expression I have to do that?

推荐答案

只测试是否存在非ascii字符，而不是测试是否存在ascii字符：

Just test for the presence of non-ascii characters instead of testing for the presence of ascii characters:

var foreignCharacters = $("#foreign_characters").val();
var rforeign = /[^\u0000-\u007f]/;

if (rforeign.test(foreignCharacters)) {
  alert("This is non-Latin Characters");
} else {
  alert("This is Latin Characters");    
}
