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
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,'-');
$("#Restaurant_Slug").val(Text);
});
其他回答
看完这些答案后，我想到了这个。
const generateSlug = (text) => text.toLowerCase()
.trim()
.replace(/[^\w- ]+/g, '')
.replace(/ /g, '-')
.replace(/[-]+/g, '-');
你可以使用你自己的函数。
试试吧:http://jsfiddle.net/xstLr7aj/
function string_to_slug(str) {
str = str.replace(/^\s+|\s+$/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;
});
});

String.prototype.slug = function(e='-'){

.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
