js实现密码校验

uPwd.addEventListener("blur", function () {//var timer = null;clearInterval(timer);tips[1].style.display = "block";var pwdVal = uPwd.value;if (pwdVal.length < 6) {tips[1].innerHTML = "密码长度必须是6-20，由字母、数字、下划线、特殊字符组成";tips[1].style.color = "red";timer = setTimeout(function () {tips[1].style.display = "none";},3000)}//密码验证规则，很实用if (/^[a-zA-Z0-9_-]{6,20}$/.test(pwdVal)) {//show.className = "success";tips[1].innerHTML = "密码强度：弱";tips[1].style.color = "gray";timer = setTimeout(function () {tips[1].style.display = "none"}, 3000);if (/^([a-z].*[A-Z])|([A-Z].*[a-z])$/.test(pwdVal)) {tips[1].innerHTML = "密码强度：中等";tips[1].style.color = "orange";timer = setTimeout(function () {tips[1].style.display = "none"}, 3000)}if (/^([a-z].*[0-9])|([A-Z].*[0-9])|[0-9].*[a-zA-Z]$/.test(pwdVal)) {tips[1].innerHTML = "密码强度：高";tips[1].style.color = "hotpink";timer = setTimeout(function () {tip[1].style.display = "none"}, 3000)}if (/^[A-Za-z0-9]+[_][A-Za-z0-9]*$/.test(pwdVal)) {tips[1].innerHTML = "密码强度:非常高";tips[1].style.color = "green";timer = setTimeout(function () {tips[1].style.display = "none"}, 3000)}repwd = this.value;} else {tips[1].innerHTML = "密码不可用，必须是6-20位数字、字母、下划线、特殊字符";tips[1].style.color = "red";repwd = null;timer = setTimeout(function () {tips[1].style.display = "none"}, 3000)}})复制代码
