JavaScript中密碼的正則表達式

Question

我已使用aspx格式的正則表達式驗證器。我已使用此express ((?=.*\\d)(?=.*[az])(?=.*[AZ])(?=.*\\W).{6,15}) ，工作正常。

我試圖在javascript中使用相同的表達式，但是為什么會失敗呢？

在JavaScript中

var regularExpression  = ((?=.*\d)(?=.*[a-z])(?=.*[A-Z])(?=.*\W).{6,15})


if (regularExpression.test(newPassword)) {
    alert("Password must be at least 6 characters, not more than 15 characters, and must include at least one upper case letter, one lower case letter, one special character and one numeric digit.");
    return false;
} 

Answer 1

您應該使用/而不是(對於RegExp

var regularExpression  = /(?=.*\d)(?=.*[a-z])(?=.*[A-Z])(?=.*\W).{6,15}/;

if (regularExpression.test(newPassword)) {
    alert("Password must be at least 6 characters, not more than 15 characters, and must include at least one upper case letter, one lower case letter, one special character and one numeric digit.");
    return false;
}
