jquery-textcomplete不使用Unicode字符，并且缺少空格 [英] jquery-textcomplete not working with Unicode characters, and missing space

问题描述

1。我正在尝试使用带有Unicode字符串数组的jquery-textcomplete。当我输入英文单词时，它可以正常工作，但不建议使用Unicode单词。我认为问题出在'term'上。检查以下代码，请帮助我：

1. I'm trying to use jquery-textcomplete with a Unicode string array. When I type an English word, it works properly, but no Unicode words are suggested. I think the problem is with the 'term'. Check the below code and please help me:

var words = ['සහන', 'වනක', 'google', 'suresh namal',  'facebook', 'github', 'microsoft', 'yahoo', 'stackoverflow'];

$('textarea').textcomplete([{
    match: /(^|\s)(\w{2,})$/,
    search: function (term, callback) {
        callback($.map(words, function (word) {
            return word.indexOf(term) === 0 ? word : null;
        }));
    },
    replace: function (word) {
        return word + ' ';
    }
}]);

2。此外，返回键存在问题。当我在'stackoverflow'之后输入'google'时，它会显示为'stackoverflowgoogle'。 'stackoverflow'和'google'之间没有空格。我怎么解决这个问题？谢谢。

2. Also, there is a problem with the return key. When I type 'google' after 'stackoverflow' it appears like 'stackoverflowgoogle'. There is no space between 'stackoverflow' and 'google'. How can I solve that? Thanks.

推荐答案

1. 问题在于你的匹配选项，其中只匹配拉丁文字（ \w ）

1. The problem is with your match option, where only the latin words are matched (\w)

\w 匹配包括下划线在内的任何字母数字字符。相当于[A-Za-z0-9 _]。

\w matches any alphanumeric character including the underscore. Equivalent to [A-Za-z0-9_].

Reference

您还应该包含unicode字符在您的RegExp中，例如： \\\-\\\

You should also include unicode characters in your RegExp, like: \u0000-\u007f

1. 这是因为使用 \s （注意小的s）在你的RegExp中，它也取代了关键字前面的'空格'：

1. this is because of using \s (notice small "s") in your RegExp, which also replaces a 'space' preceding the keyword:

\ 匹配单个空白字符，包括空格（...）

\s matches a single white space character, including space (...)

参考

您可以使用 \S （大写S）匹配单个字符其他比空间，还有一个 * （星号）与前面的空格匹配0次或更多次。

You could use there \S (capital "S") which matches a single character other than space, along with a * (asterisk) which matches the preceding space 0 or more times.

它可能不是最漂亮的RegExp，但应该为你完成这项工作：

It's probably not a prettiest RegExp, but should do the job for you:

$('textarea').textcomplete([{
    match: /(^|\S*)([^\u0000-\u007f]{2,}|\w{2,})$/,
    search: function (term, callback) {
        callback($.map(words, function (word) {
            return word.indexOf(term) > -1 ? word : null;
        }));
    },
    replace: function (word) {
        return word+' ';
    }
}]);
