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','-');
$("#Restaurant_Slug").val(Text);
});
当前回答
var slug = function(str) {
str = str.replace(/^\s+|\s+$/g, ''); // trim
str = str.toLowerCase();
// remove accents, swap ñ for n, etc
var from = "ãàáäâẽèéëêìíïîõòóöôùúüûñç·/_,:;";
var to = "aaaaaeeeeeiiiiooooouuuunc------";
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;
};
并尝试
slug($('#field').val())

编辑: 扩展到更多特定于语言的字符:
var from = "ÁÄÂÀÃÅČÇĆĎÉĚËÈÊẼĔȆĞÍÌÎÏİŇÑÓÖÒÔÕØŘŔŠŞŤÚŮÜÙÛÝŸŽáäâàãåčçćďéěëèêẽĕȇğíìîïıňñóöòôõøðřŕšşťúůüùûýÿžþÞĐđßÆa·/_,:;";
var to = "AAAAAACCCDEEEEEEEEGIIIIINNOOOOOORRSSTUUUUUYYZaaaaaacccdeeeeeeeegiiiiinnooooooorrsstuuuuuyyzbBDdBAa------";

private string ToSeoFriendly(string title, int maxLength) {
var match = Regex.Match(title.ToLower(), "[\\w]+");
StringBuilder result = new StringBuilder("");
bool maxLengthHit = false;
while (match.Success && !maxLengthHit) {
if (result.Length + match.Value.Length <= maxLength) {
result.Append(match.Value + "-");
} else {
maxLengthHit = true;
// 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();
}
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;
});
});
你可能想看看speakingURL插件，然后你就可以:
$("#Restaurant_Name").on("keyup", function () {
var slug = getSlug($("#Restaurant_Name").val());
$("#Restaurant_Slug").val(slug);
});
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, '-');
