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);
});

还有一个。短且保留特殊字符:
想象力是丛林=>想象力和丛林
function slugify (text) {
const a = 'àáäâãèéëêìíïîòóöôùúüûñçßÿœæŕśńṕẃǵǹḿǘẍźḧ·/_,:;'
const b = 'aaaaaeeeeiiiioooouuuuncsyoarsnpwgnmuxzh------'
const p = new RegExp(a.split('').join('|'), 'g')
return text.toString().toLowerCase()
.replace(/\s+/g, '-') // Replace spaces with -
.replace(p, c =>
b.charAt(a.indexOf(c))) // Replace special chars
.replace(/&/g, '-and-') // Replace & with 'and'
.replace(/[^\w\-]+/g, '') // Remove all non-word chars
.replace(/\-\-+/g, '-') // Replace multiple - with single -
.replace(/^-+/, '') // Trim - from start of text
.replace(/-+$/, '') // Trim - from end of text
}
其他回答
private string ToSeoFriendly(string title, int maxLength) {
var match = Regex.Match(title.ToLower(), "[\\w]+");
StringBuilder result = new StringBuilder("");
bool maxLengthHit = false;
while (match.Success && !maxLengthHit) {
if (result.Length + match.Value.Length <= maxLength) {
result.Append(match.Value + "-");
} else {
maxLengthHit = true;
// Handle a situation where there is only one word and it is greater than the max length.
if (result.Length == 0) result.Append(match.Value.Substring(0, maxLength));
}
match = match.NextMatch();
}
// Remove trailing '-'
if (result[result.Length - 1] == '-') result.Remove(result.Length - 1, 1);
return result.ToString();
}
希望这能挽救某人的一天…
/* Encode string to slug */ function convertToSlug( str ) { //replace all special characters | symbols with a space str = str.replace(/[`~!@#$%^&*()_\-+=\[\]{};:'"\\|\/,.<>?\s]/g, ' ') .toLowerCase(); // trim spaces at start and end of string str = str.replace(/^\s+|\s+$/gm,''); // replace space with dash/hyphen str = str.replace(/\s+/g, '-'); document.getElementById("slug-text").innerHTML = str; //return str; } <input type="text" onload="convertToSlug(this.value)" onkeyup="convertToSlug(this.value)" value="Try it Yourself" /> <p id="slug-text"></p>
将这里的答案中的各种元素与normalize结合起来可以提供很好的覆盖率。保持操作的顺序，以增量地清理url。
function clean_url(s) {
return s.toString().normalize('NFD').replace(/[\u0300-\u036f]/g, "") //remove diacritics
.toLowerCase()
.replace(/\s+/g, '-') //spaces to dashes
.replace(/&/g, '-and-') //ampersand to and
.replace(/[^\w\-]+/g, '') //remove non-words
.replace(/\-\-+/g, '-') //collapse multiple dashes
.replace(/^-+/, '') //trim starting dash
.replace(/-+$/, ''); //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。

看完这些答案后，我想到了这个。
const generateSlug = (text) => text.toLowerCase()
.trim()
.replace(/[^\w- ]+/g, '')
.replace(/ /g, '-')
.replace(/[-]+/g, '-');
