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','-');
$("#Restaurant_Slug").val(Text);
});
当前回答
function slugify(content) {
return content.toLowerCase().replace(/ /g,'-').replace(/[^\w-]+/g,'');
}
// slugify('Hello World');
// this will return 'hello-world';
这对我来说很好。
在CodeSnipper上找到的
其他回答
接受的答案没有满足我的需求(它允许下划线，在开头和结尾不处理破折号，等等)，而其他答案有其他不适合我的用例的问题，所以这里是我想出的slugify函数:
function slugify(string) {
return string.trim() // Remove surrounding whitespace.
.toLowerCase() // Lowercase.
.replace(/[^a-z0-9]+/g,'-') // Find everything that is not a lowercase letter or number, one or more times, globally, and replace it with a dash.
.replace(/^-+/, '') // Remove all dashes from the beginning of the string.
.replace(/-+$/, ''); // 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。
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>

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 $this;
};
这帮我解决了同样的问题!
我找到了一个很好的完整的英语解决方案
function slugify(string) {
return string
.toString()
.trim()
.toLowerCase()
.replace(/\s+/g, "-")
.replace(/[^\w\-]+/g, "")
.replace(/\-\-+/g, "-")
.replace(/^-+/, "")
.replace(/-+$/, "");
}
下面是一些使用的例子:
slugify(12345);
// "12345"
slugify(" string with leading and trailing whitespace ");
// "string-with-leading-and-trailing-whitespace"
slugify("mIxEd CaSe TiTlE");
// "mixed-case-title"
slugify("string with - existing hyphens -- ");
// "string-with-existing-hyphens"
slugify("string with Special™ characters");
// "string-with-special-characters"
