密碼強度JavaScript

-2

你能幫我找出爲什麼我的代碼不工作嗎？如果密碼是，我必須chchck a）4-6個字符長度（必須包含一個或多個數字）以使密碼中等 b）強度要求爲7以上的字符（必須包含一個或多個數字）。 c）除a）和b）之外的任何東西都很弱。密碼強度JavaScript

幾點建議 - 你應該確保重新驗證這些密碼您的服務器端的限制。「惡意用戶」繞過這些客戶端檢查將非常容易。 – Lix

它只適用於學校項目使用 – Matias513

也有邪惡的學生;）我所說的是，任何知道如何使用chrome開發工具的用戶都可以修改任何在客戶端執行的安全檢查。 – Lix

關注該https://jsfiddle.net/umesh1990/hxjf74cz/35/# 我已經做到了這一點使用JavaScript
