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','-');
$("#Restaurant_Slug").val(Text);
});
当前回答
function slugify(text){
return text.toString().toLowerCase()
.replace(/\s+/g, '-') // Replace spaces with -
.replace(/[^\u0100-\uFFFF\w\-]/g,'-') // Remove all non-word chars ( fix for UTF-8 chars )
.replace(/\-\-+/g, '-') // Replace multiple - with single -
.replace(/^-+/, '') // Trim - from start of text
.replace(/-+$/, ''); // 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);
});
其他回答
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();
}
我不知道“鼻涕虫”这个词从何而来，但我们开始吧:
function convertToSlug(Text) {
return Text.toLowerCase()
.replace(/ /g, '-')
.replace(/[^\w-]+/g, '');
}
第一个replace方法将空格更改为连字符，第二，replace删除除字母数字、下划线或连字符以外的任何内容。
如果你不希望“like- this”变成“like- this”，你可以用这个:
function convertToSlug(Text) {
return Text.toLowerCase()
.replace(/[^\w ]+/g, '')
.replace(/ +/g, '-');
}
这将在第一次替换时删除连字符(但没有空格)，在第二次替换时将连续的空格压缩为单个连字符。
所以"like-this"就变成了"like-this"。
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
