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);  
});

接受的答案没有满足我的需求(它允许下划线,在开头和结尾不处理破折号,等等),而其他答案有其他不适合我的用例的问题,所以这里是我想出的slugify函数:

function slugify(string) {
    return string.trim() // Remove surrounding whitespace.
    .toLowerCase() // Lowercase.
    .replace(/[^a-z0-9]+/g,'-') // Find everything that is not a lowercase letter or number, one or more times, globally, and replace it with a dash.
    .replace(/^-+/, '') // Remove all dashes from the beginning of the string.
    .replace(/-+$/, ''); // Remove all dashes from the end of the string.
}

这将把' foo!!BAR_-_-_baz-'(注意开头的空格)变成foo-bar-baz。

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();
}

希望这能挽救某人的一天…

/* Encode string to slug */ function convertToSlug( str ) { //replace all special characters | symbols with a space str = str.replace(/[`~!@#$%^&*()_\-+=\[\]{};:'"\\|\/,.<>?\s]/g, ' ') .toLowerCase(); // trim spaces at start and end of string str = str.replace(/^\s+|\s+$/gm,''); // replace space with dash/hyphen str = str.replace(/\s+/g, '-'); document.getElementById("slug-text").innerHTML = str; //return str; } <input type="text" onload="convertToSlug(this.value)" onkeyup="convertToSlug(this.value)" value="Try it Yourself" /> <p id="slug-text"></p>

String.prototype.slug = function(e='-'){
  let $this=this
        .toUpperCase()
        .toLowerCase()
        .normalize('NFD')
        .trim()
        .replace(/\s+/g,e)
        .replace(/-\+/g,'')
        .replace(/-+/g,e)
        .replace(/^-/g,'')
        .replace(/-$/g,'')
        .replace(/[^\w-]/g,'');
  return $this
        .toUpperCase()
        .toLowerCase()
        .normalize('NFD')
        .trim()
        .replace(/\s+/g,e)
        .replace(/-\+/g,'')
        .replace(/-+/g,e)
        .replace(/^-/g,'')
        .replace(/-$/g,'')
        .replace(/[^\w-]/g,'');
}

我过滤了两次,因为可能会有更多不需要的字符

你所需要的只是一个加号:)

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