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);
});

你可以使用你自己的函数。
试试吧:http://jsfiddle.net/xstLr7aj/
function string_to_slug(str) {
str = str.replace(/^\s+|\s+$/g, ''); // trim
str = str.toLowerCase();
// remove accents, swap ñ for n, etc
var from = "àáäâèéëêìíïîòóöôùúüûñç·/_,:;";
var to = "aaaaeeeeiiiioooouuuunc------";
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;
}
$(document).ready(function() {
$('#test').submit(function(){
var val = string_to_slug($('#t').val());
alert(val);
return false;
});
});
其他回答
$("#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

jQuery.fn.slug = function(options) {
var settings = {
slug: 'slug', // Class used for slug destination input and span. The span is created on $(document).ready()
hide: true // Boolean - By default the slug input field is hidden, set to false to show the input field and hide the span.
};
if(options) {
jQuery.extend(settings, options);
}
$this = $(this);
$(document).ready( function() {
if (settings.hide) {
$('input.' + settings.slug).after("<span class="+settings.slug+"></span>");
$('input.' + settings.slug).hide();
}
});
makeSlug = function() {
var slug = jQuery.trim($this.val()) // Trimming recommended by Brooke Dukes - http://www.thewebsitetailor.com/2008/04/jquery-slug-plugin/comment-page-1/#comment-23
.replace(/\s+/g,'-').replace(/[^a-zA-Z0-9\-]/g,'').toLowerCase() // See http://www.djangosnippets.org/snippets/1488/
.replace(/\-{2,}/g,'-'); // If we end up with any 'multiple hyphens', replace with just one. Temporary bugfix for input 'this & that'=>'this--that'
$('input.' + settings.slug).val(slug);
$('span.' + settings.slug).text(slug);
}
$(this).keyup(makeSlug);
return $this;
};
这帮我解决了同样的问题!
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, '-');
