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);  
});

还有一个。短且保留特殊字符:

想象力是丛林=>想象力和丛林

function slugify (text) {
  const a = 'àáäâãèéëêìíïîòóöôùúüûñçßÿœæŕśńṕẃǵǹḿǘẍźḧ·/_,:;'
  const b = 'aaaaaeeeeiiiioooouuuuncsyoarsnpwgnmuxzh------'
  const p = new RegExp(a.split('').join('|'), 'g')

  return text.toString().toLowerCase()
    .replace(/\s+/g, '-')           // Replace spaces with -
    .replace(p, c =>
        b.charAt(a.indexOf(c)))     // Replace special chars
    .replace(/&/g, '-and-')         // Replace & with 'and'
    .replace(/[^\w\-]+/g, '')       // Remove all non-word chars
    .replace(/\-\-+/g, '-')         // Replace multiple - with single -
    .replace(/^-+/, '')             // Trim - from start of text
    .replace(/-+$/, '')             // Trim - from end of text
}

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);        
});

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, '-');
