Javascript - 從標題中刪除特殊字符的正則表達式

Question

我試圖從我的標題中刪除特殊字符並將其轉換為 url-schema。 我可以通過使用 .replace 方法來完成此操作，例如： title.replace(/[^A-Za-z0-9\\-/s]/g, " ");

當標題中有括號時，我遇到了問題。 我能夠刪除括號，但它會在最后留下一個空格，然后我用-填充空格以創建 URL 模式，這給我帶來了一些問題。

如何調整下面的代碼以刪除（貓和狗）周圍的括號，以免留下空格？

這就是我當前代碼的情況： "Pet Supplies Cat and Dog "

 let title = "Pet Supplies (Cat and Dog)" let cleanTitle = "" cleanTitle = title.replace(/[^A-Za-z0-9\\-/s]/g, " "); cleanTitle = cleanTitle.toLowerCase(); cleanTitle = cleanTitle.replace(new RegExp(" ", "g"), "-"); cleanTitle = cleanTitle.replace("-and", ""); cleanTitle = cleanTitle.replace(new RegExp("---", "g"), "--"); cleanTitle = cleanTitle.replace(new RegExp("--", "g"), "-"); console.log(cleanTitle)

我的預期結果是： pet-supplies-cat-dog

Answer 1

您可以使用

 let title = "Pet Supplies (Cat and Dog)" title = title.toLowerCase() // Turn to lower .match(/[a-z0-9\\s-]+/g) // Extract all alnum + hyphen and whitespace chunks .map(x => x.trim().split(/\\s+/).join("-")) // Trim the items, split with whitespace and join with a hyphen .join("-") // Join the items with a hyphen .replace(/-and\\b/g, ''); // Remove whole word -and console.log(title);

Answer 2

可能有更優雅的方法來做到這一點，但您只想刪除開頭和結尾的特殊字符而不添加空格字符（或添加后刪除）。 這可以通過兩個額外的替換來完成：

 let title = "Pet Supplies (Cat and Dog)" let cleanTitle = "" cleanTitle = title.replace(/[^A-Za-z0-9\\-/s]/g, " "); cleanTitle = cleanTitle.replace(/^ /g, ""); cleanTitle = cleanTitle.replace(/ $/g, ""); cleanTitle = cleanTitle.toLowerCase(); cleanTitle = cleanTitle.replace(new RegExp(" ", "g"), "-"); cleanTitle = cleanTitle.replace("-and", ""); cleanTitle = cleanTitle.replace(new RegExp("---", "g"), "--"); cleanTitle = cleanTitle.replace(new RegExp("--", "g"), "-"); console.log(cleanTitle)

Answer 3

您可以通過以下方式實現輸出：

 let title = "Pet Supplies (Cat and Dog)" let cleanTitle = "" cleanTitle = title.replace(/and/g,''); // removing all "and" cleanTitle = cleanTitle.replace(/\\s+/g, '-'); // replacing all spaces by "-" cleanTitle = cleanTitle.replace(/([()])/g, ''); // removing all "()" cleanTitle = cleanTitle.toLowerCase(); // converting to lowercases console.log(cleanTitle)
