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);
});

/* 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>

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,'-');
$("#Restaurant_Slug").val(Text);
});
var slug = function(str) {
str = str.replace(/^\s+|\s+$/g, ''); // trim
str = str.toLowerCase();
// remove accents, swap ñ for n, etc
var from = "ãàáäâẽèéëêìíïîõòóöôùúüûñç·/_,:;";
var to = "aaaaaeeeeeiiiiooooouuuunc------";
for (var i = 0, l = from.length; i < l; i++) {
str = str.replace(new RegExp(from.charAt(i), 'g'), to.charAt(i));
}
str = str.replace(/[^a-z0-9 -]/g, '') // remove invalid chars
.replace(/\s+/g, '-') // collapse whitespace and replace by -
.replace(/-+/g, '-'); // collapse dashes
return str;
};
并尝试
slug($('#field').val())

编辑: 扩展到更多特定于语言的字符:
var from = "ÁÄÂÀÃÅČÇĆĎÉĚËÈÊẼĔȆĞÍÌÎÏİŇÑÓÖÒÔÕØŘŔŠŞŤÚŮÜÙÛÝŸŽáäâàãåčçćďéěëèêẽĕȇğíìîïıňñóöòôõøðřŕšşťúůüùûýÿžþÞĐđßÆa·/_,:;";
var to = "AAAAAACCCDEEEEEEEEGIIIIINNOOOOOORRSSTUUUUUYYZaaaaaacccdeeeeeeeegiiiiinnooooooorrsstuuuuuyyzbBDdBAa------";
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

更强大的纯JavaScript段代码生成方法。它基本上支持所有西里尔字母和许多变音字母(德语、丹麦语、法语、土耳其语、乌克兰语等)的音译，但可以轻松扩展。
function makeSlug(str) { var from="а б в г д е ё ж з и й к л м н о п р с т у ф х ц ч ш щ ъ ы ь э ю я ā ą ä á à â å č ć ē ę ě é è ê æ ģ ğ ö ó ø ǿ ô ő ḿ ʼn ń ṕ ŕ ş ü ß ř ł đ þ ĥ ḧ ī ï í î ĵ ķ ł ņ ń ň ř š ś ť ů ú û ứ ù ü ű ū ý ÿ ž ź ż ç є ґ".split(' '); var to= "a b v g d e e zh z i y k l m n o p r s t u f h ts ch sh shch # y # e yu ya a a ae a a a a c c e e e e e e e g g oe o o o o o m n n p r s ue ss r l d th h h i i i i j k l n n n r s s t u u u u u u u u y y z z z c ye g".split(' '); str = str.toLowerCase(); // remove simple HTML tags str = str.replace(/(<[a-z0-9\-]{1,15}[\s]*>)/gi, ''); str = str.replace(/(<\/[a-z0-9\-]{1,15}[\s]*>)/gi, ''); str = str.replace(/(<[a-z0-9\-]{1,15}[\s]*\/>)/gi, ''); str = str.replace(/^\s+|\s+$/gm,''); // trim spaces for(i=0; i<from.length; ++i) str = str.split(from[i]).join(to[i]); // Replace different kind of spaces with dashes var spaces = [/( | | )/gi, /(—|–|‑)/gi, /[(_|=|\\|\,|\.|!)]+/gi, /\s/gi]; for(i=0; i<from.length; ++i) str = str.replace(spaces[i], '-'); str = str.replace(/-{2,}/g, "-"); // remove special chars like & str = str.replace(/&[a-z]{2,7};/gi, ''); str = str.replace(/&#[0-9]{1,6};/gi, ''); str = str.replace(/&#x[0-9a-f]{1,6};/gi, ''); str = str.replace(/[^a-z0-9\-]+/gmi, ""); // remove all other stuff str = str.replace(/^\-+|\-+$/gm,''); // trim edges return str; }; document.getElementsByTagName('pre')[0].innerHTML = makeSlug(" <br/> ‪Про&вер<strong>ка_тран</strong>с…литеърьации\rюга\nи–южного округа\t \nс\tёжикам´и со\\всеми–друзьями\tтоже.Danke schön!ich heiße=КáÞÿá-Skånske,København çağatay rí gé tőr zöldülésetekről - .
