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

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。

            // 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();
}

    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.

$(document).ready( function() {

        $('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(/\-{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"

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

我创建了一个插件来实现在大多数语言:http://leocaseiro.com.br/jquery-plugin-string-to-slug/

默认的用法:

$(document).ready( function() {
    $("#string").stringToSlug();
});

是很容易有stringToSlug jQuery插件
