JavaScript无法识别土耳其语字符

本文介绍了JavaScript无法识别土耳其语字符的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我有此代码:

if (term.length > 0) {
  var inputVal = $("#input").val();
  if (inputVal.indexOf("jason") !== -1) {
    results = $.ui.autocomplete.filter(table, term);
  }
}

这有效.但是，当我将"jason" 更改为jasön" 或jasün" 或其他土耳其语字符时，它不起作用.是因为js文件的编码吗?我将编码更改为Unicode(带签名的utf-8)-代码页65001，然后是土耳其语ISO 28599，但没有用.你能告诉我该怎么办吗?谢谢.

This works. But when I changed "jason" to "jasön" or "jasün" or something else which is a Turkish character, it doesn't work. Is it because the encoding of the js file? I changed the encoding to Unicode (utf-8 with signature) - Codepage 65001 then Turkish ISO 28599 but it didn't work. Can you tell me what I should do? Thanks.

推荐答案

它可以识别土耳其语字符，但是您正在对所述字符串进行相等性检查.您需要了解的是，即使ö只是带有重音符号的 o ，它仍然是一个不同字符，因此使您的条件错误，即使您没有进行三重相等检查.

It does recognize Turkish characters, but you are doing an equality check on said string. What you have to understand is that even if ö is only an o with an accent, it's still a different character, thus making your conditional falsy, even if you are not doing a triple equality check.

'ö' == 'o'  // false
'ö' === 'o' // false

您应该做的是将输入值转换为没有重音符号的字符串，因为这显然是您所期望的.并且这个问题正是您要寻找的，我会说将是最好的答案，因为它非常干净且易于使用

What you should do instead is convert the input value into a string without accents, since it's apparently what you were expecting. And this question is exactly what you are looking for, and I would say this answer would be the best one if you have access to ES6 features since it's pretty clean and simple to use

function convert (str) {
  return str.normalize('NFD').replace(/[\u0300-\u036f]/g, '')
}

if (term.length > 0) {
  var inputVal = convert($('#input').val())
  if (inputVal.indexOf('jason') !== -1) {
    results = $.ui.autocomplete.filter(table, term)
  }
}

否则，如果没有ES6选项，则最佳答案应该可以使用，只需创建一个函数util您可以在需要的任何地方重复使用.

Otherwise if ES6 is not an option, the top answer should be fine to use, just create a function util that you can reuse anywhere you need to.

关于文件的编码，如果要处理土耳其语确实具有的特殊字符，则应使用 utf-8 .

Regarding the encoding of the file, you should use utf-8 if dealing with special chars that Turkish does have.
