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);
});

.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!

首先，正则表达式不应该有引号，所以'/\s/g'应该是/\s/g
为了用破折号替换所有非字母数字字符，这应该可以工作(使用示例代码):
$("#Restaurant_Name").keyup(function() {
var Text = $(this).val();
Text = Text.toLowerCase();
Text = Text.replace(/[^a-zA-Z0-9]+/g,'-');
$("#Restaurant_Slug").val(Text);
});
这应该能奏效……
我找到了一个很好的完整的英语解决方案
function slugify(string) {
return string
.toString()
.trim()
.toLowerCase()
.replace(/\s+/g, "-")
.replace(/[^\w\-]+/g, "")
.replace(/\-\-+/g, "-")
.replace(/^-+/, "")
.replace(/-+$/, "");
}
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"

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。

这帮我解决了同样的问题!
function slugify(text){
return text.toString().toLowerCase()
.replace(/\s+/g, '-') // Replace spaces with -
.replace(/[^\u0100-\uFFFF\w\-]/g,'-') // Remove all non-word chars ( fix for UTF-8 chars )
.replace(/\-\-+/g, '-') // Replace multiple - with single -
.replace(/^-+/, '') // Trim - from start of text
.replace(/-+$/, ''); // Trim - from end of text
}
*基于https://gist.github.com/mathewbyrne/1280286
现在你可以转换这个字符串:
Barack_Obama Барак_Обама ~!@#$%^&*()+/-+?><:";'{}[]\|`
成:
barack_obama-барак_обама
应用于你的代码:
$("#Restaurant_Name").keyup(function(){
var Text = $(this).val();
Text = slugify(Text);
$("#Restaurant_Slug").val(Text);
});
