验证手机号的正则表达式
<p><label>手机号:</label><input type="text" name="phone" id="phone" value="" placeholder="请输入手机号码"/></p>
<p>
<input type="text" name="yanzhengma" id="yanzhengma" value="" placeholder="请输入验证码"/>
<input type="hidden" id="yanzheng">
<input type="button" name="huoquYanzhengma" id="huoquYanzhengma" value="获取验证码"/>
</p>
$("#huoquYanzhengma").click(function(){
if($("#phone").val()==""||$("#phone").val()==null){
$("#tishi").show();
$("#YGTp").text("请输入手机号!");
return false;
}else{
var myreg = /^1[3|4|5|7|8][0-9]\d{4,8}$/; //手机号校验
if(!myreg.test($("#phone").val())) {
$("#tishi").show();
$("#YGTp").text("请填写 有效的手机号码!");
return;
}
}
定时器:输入手机号之后显示60秒倒计时
settime($(‘#huoquYanzhengma’));
var countdown=60;
function settime(val) {
if(countdown == 0){
val.attr(“disabled”,false);
val.val(“重新发送”);
countdown = 60;
}else{
val.attr(“disabled”, true);
val.val(“重新发送(” + countdown + “)”);
countdown–;
setTimeout(function() {
settime(val);
},1000);
}
}
