前端学习

jQuery validator addMethod javascript

jQuery.validate是一款非常不错的表单验证工具，简单易上手，而且能达到很好的体验效果

一、用前必备
官方网站：http://bassistance.de/jquery-plugins/jquery-plugin-validation/（注意下载最新版）
API: http://jquery.bassistance.de/api-browser/plugins.html当前版本：1.5.5
需要JQuery版本：1.2.6+, 兼容 1.3.2

废话不多说，直接看代码

1.HTML 页面代码

<form id="register_form" class="form-horizontal" name="register_form" method="post" action="register.htm?cmd=register" enctype="application/x-www-form-urlencoded">
					<input type="hidden" id="recommenderId" name="recommenderId" value="$!recommenderId"/>
						<div class="control-group">
							<label class="control-label" for="inputUserName">用户名</label>
							<div class="controls">
								<input type="text" id="inputUserName" name="userName" autocomplete="off"/>
							</div>
						</div>
						<div class="control-group">
							<label class="control-label" for="inputPassword">密码</label>
							<div class="controls">
								<input type="password" id="inputPassword" name="password" autocomplete="off"/>
							</div>
						</div>
						<div class="control-group">
							<label class="control-label" for="inputRepassword">重复密码</label>
							<div class="controls">
								<input type="password" id="inputRepassword" name="repassword" autocomplete="off"/>
							</div>
						</div>
						<div class="control-group">
							<label class="control-label" for="inputPhoneNumber">手机号码</label>
							<div class="controls">
								<input type="text" class="u" id="inputPhoneNumber" name="phoneNumber"/>
								<span class="help-inline">
									<button class="btn btn-small" id="send" type="button" autocomplete="off">发送手机验证码</button>
								</span>
							</div>
						</div>
						<div class="control-group">
							<label class="control-label" for="inputVcode">手机验证码</label>
							<div class="controls">
								<input type="text" id="inputVcode" name="phoneVerifyCode" autocomplete="off"/>
							</div>
						</div>

				</form>
