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
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();
}

希望这能挽救某人的一天…
/* Encode string to slug */ function convertToSlug( str ) { //replace all special characters | symbols with a space str = str.replace(/[`~!@#$%^&*()_\-+=\[\]{};:'"\\|\/,.<>?\s]/g, ' ') .toLowerCase(); // trim spaces at start and end of string str = str.replace(/^\s+|\s+$/gm,''); // replace space with dash/hyphen str = str.replace(/\s+/g, '-'); document.getElementById("slug-text").innerHTML = str; //return str; } <input type="text" onload="convertToSlug(this.value)" onkeyup="convertToSlug(this.value)" value="Try it Yourself" /> <p id="slug-text"></p>
$("#Restaurant_Name").keyup(function() {
var Text = $(this).val();
Text = Text.toLowerCase();
Text = Text.replace(/[^a-zA-Z0-9]+/g,'-');
$("#Restaurant_Slug").val(Text);
});
这段代码正在工作
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, '-');
