我在CodeIgniter的一个应用程序上工作,我试图使表单上的字段动态生成URL段塞。我想做的是删除标点符号,将其转换为小写字母,并将空格替换为连字符。比如,Shane's Rib Shack会变成shanes-rib-shack。

这是我目前所掌握的。小写部分很容易,但替换似乎根本不起作用,我也不知道要删除标点符号:

$("#Restaurant_Name").keyup(function() {
  var Text = $(this).val();
  Text = Text.toLowerCase();
  Text = Text.replace('/\s/g','-');
  $("#Restaurant_Slug").val(Text);  
});

当前回答

function slugify(text){
  return text.toString().toLowerCase()
    .replace(/\s+/g, '-')           // Replace spaces with -
    .replace(/[^\u0100-\uFFFF\w\-]/g,'-') // Remove all non-word chars ( fix for UTF-8 chars )
    .replace(/\-\-+/g, '-')         // Replace multiple - with single -
    .replace(/^-+/, '')             // Trim - from start of text
    .replace(/-+$/, '');            // Trim - from end of text
}

*基于https://gist.github.com/mathewbyrne/1280286

现在你可以转换这个字符串:

Barack_Obama       Барак_Обама ~!@#$%^&*()+/-+?><:";'{}[]\|`

成:

barack_obama-барак_обама

应用于你的代码:

$("#Restaurant_Name").keyup(function(){
    var Text = $(this).val();
    Text = slugify(Text);
    $("#Restaurant_Slug").val(Text);
});

我创建了一个插件来实现在大多数语言:http://leocaseiro.com.br/jquery-plugin-string-to-slug/

默认的用法:

$(document).ready( function() {
    $("#string").stringToSlug();
});

是很容易有stringToSlug jQuery插件

将这里的答案中的各种元素与normalize结合起来可以提供很好的覆盖率。保持操作的顺序,以增量地清理url。

function clean_url(s) {
    return s.toString().normalize('NFD').replace(/[\u0300-\u036f]/g, "") //remove diacritics
            .toLowerCase()
            .replace(/\s+/g, '-') //spaces to dashes
            .replace(/&/g, '-and-') //ampersand to and
            .replace(/[^\w\-]+/g, '') //remove non-words
            .replace(/\-\-+/g, '-') //collapse multiple dashes
            .replace(/^-+/, '') //trim starting dash
            .replace(/-+$/, ''); //trim ending dash
}

normize ('NFD')将重音字符分解为它们的组成部分,即基本字母加上变音符符号(重音部分)。Replace (/[\u0300-\u036f]/g, "")清除所有变音符,只保留基本字母。其余部分用内联注释解释。

$("#Restaurant_Name").keyup(function() {
  var Text = $(this).val();
  Text = Text.toLowerCase();
  Text = Text.replace(/[^a-zA-Z0-9]+/g,'-');
  $("#Restaurant_Slug").val(Text);        
});

这段代码正在工作

private string ToSeoFriendly(string title, int maxLength) {
    var match = Regex.Match(title.ToLower(), "[\\w]+");
    StringBuilder result = new StringBuilder("");
    bool maxLengthHit = false;
    while (match.Success && !maxLengthHit) {
        if (result.Length + match.Value.Length <= maxLength) {
            result.Append(match.Value + "-");
        } else {
            maxLengthHit = true;
            // Handle a situation where there is only one word and it is greater than the max length.
            if (result.Length == 0) result.Append(match.Value.Substring(0, maxLength));
        }
        match = match.NextMatch();
    }
    // Remove trailing '-'
    if (result[result.Length - 1] == '-') result.Remove(result.Length - 1, 1);
    return result.ToString();
}
