在一次机会下,帮朋友写了个用户注册的前台验证,输入内容通过正则验证,简单快捷,与大家分享
以下是html代码
<div class="form-group has-error required"> <span class="col-md-2" for="">手 机:</span> <input id="phone" name="phone" placeholder="请输入手机号码" type="text" onblur="checkPhone()"> <span class="error">*</span> <span id="span_phone"></span></div><div class="form-group has-error required"> <span class="col-md-2" for="">邮 件:</span> <input id="email" name="email" placeholder="请输入邮箱地址" type="text" onblur="checkEmail()"> <label class="error">*</label> <label class="help-block col-md-offset-2">请输入正确的邮箱地址</label> <span id="span_email"></span></div><div class="form-group has-error required"> <span class="col-md-2" for="">设 置 密 码:</span> <input id="password" name="password" placeholder="请输入8位密码" type="password" onblur="checkPwd()"> <label class="error">*</label> <label class="help-block col-md-offset-2">至少包含一位大写字母,小写字母,数字,特殊字符</label> <span id="span_pwd"></span></div><div class="form-group has-error required"> <span class="col-md-2" for="">确 认 密 码:</span> <input id="password2" name="password2" placeholder="请输入8位密码" type="password" onblur="checkPwd2()"> <label class="error">*</label> <label class="help-block col-md-offset-2">再次确认密码</label> <span id="span_pwd2"></span></div><div class="btn_nav"> <input class="submit_zc" id="submit" name="submit" value="立即注册" type="submit" onclick="return mysubmit()"></div>
以下是JS代码
<script type="text/javascript"> function checkPhone(){ var phone = document.getElementById("phone").value.trim(); if(phone.length == 0){ document.getElementById("span_phone").innerHTML = "<font color='red'>手机号不能为空"; document.getElementById("phone").focus(); } else if(!(/^1[358][0-9]{9}$/.test(phone))){ document.getElementById("span_phone").innerHTML = "<font color='red'>不是完整的11位手机号或者正确的手机号"; document.getElementById("phone").focus(); return false; } else document.getElementById("span_phone").innerHTML = ""; return true; }; function checkEmail(){ var email = document.getElementById("email").value.trim(); if(email.length == 0){ document.getElementById("span_email").innerHTML = "<font color='red'>邮箱不能为空"; document.getElementById("email").focus(); } else if(!(/^([a-zA-Z0-9_\.\-])+\@(([a-zA-Z0-9\-])+\.)+([a-zA-Z0-9]{2,4})+$/.test(email))){ document.getElementById("span_email").innerHTML = "<font color='red'>格式错误,邮箱账号@域名如:good@qq.com"; document.getElementById("email").focus(); return false; }else document.getElementById("span_email").innerHTML = ""; return true; }; function checkPwd(){ var password = document.getElementById("password").value.trim(); if(password.length == 0){ document.getElementById("span_pwd").innerHTML = "<font color='red'>密码不能为空"; document.getElementById("password").focus(); } else if(!(/^(?=.*?[a-z])(?=.*?[A-Z])(?=.*?\d)(?=.*?[#@*&.]).*$/.test(password))){ document.getElementById("span_pwd").innerHTML = "<font color='red'>格式错误,至少包含一位大写字母,小写字母,数字,特殊字符"; document.getElementById("password").focus(); return false; }else document.getElementById("span_pwd").innerHTML = ""; return true; }; function checkPwd2(){ var password = document.getElementById("password").value.trim(); var password2 = document.getElementById("password2").value.trim(); if(password2.length == 0){ document.getElementById("span_pwd2").innerHTML = "<font color='red'>密码不能为空"; document.getElementById("password2").focus(); } else if(password != password2){ document.getElementById("span_pwd2").innerHTML = "<font color='red'>两次输入不一致"; return false; }else document.getElementById("span_pwd2").innerHTML = ""; return true; }; function mySubmit() { if (checkPhone() && checkEmail() && checkPwd() && checkPwd2()) { alert("信息提交成功!"); return true; } else { alert("信息填写错误无法提交,请填写正确后提交!"); return false; } }; function checkName() { var userName = document.getElementById("userName").value.trim(); var filter = /^[a-zA-Z][a-zA-Z0-9_]{5,16}$/; if (userName.length == 0) { document.getElementById("name").innerHTML = "<font color='red'>用户名不能为空"; document.getElementById("userName").focus(); return false; } else if (!filter.test(userName)) { document.getElementById("name").innerHTML = "<font color='red'>用户名格式错误(以字母开头,由字母、数字、下划线组成限6-16位)"; document.getElementById("userName").focus(); return false; } else document.getElementById("name").innerHTML = "用户名可用"; return true;}</script>
