最近做项目时碰到一个需求,就是在移动端支付页面点击支付按钮弹出一个支付键盘,类似于支付宝的那种。由于项目只是单纯的手机网站,而并非app,所以这个功能得由前端来实现。话不多说,先上图看看效果。

尼玛,这不就是支付宝app那个支付键盘吗? 没错,咱们UI就是参照支付宝做的这个键盘。你可能会问,为什么不直接调用支付宝提供的支付接口呢。额,因为项目需要,这里就不多解释了。

我们先看一下实现后的效果图

HTML部分


<!-- 支付键盘 -->
 <divclass="pay-container">
 <divclass="pay-title">
 <spanclass="pay-title-remove">×</span>
 输入支付密码
 </div>
 <divclass="pay-body">
 <divclass="input-container">
 <inputclass="input-item"type="password"readonly>
 <inputclass="input-item"type="password"readonly>
 <inputclass="input-item"type="password"readonly>
 <inputclass="input-item"type="password"readonly>
 <inputclass="input-item"type="password"readonly>
 <inputclass="input-item"type="password"readonly>
 </div>
 <divclass="forgetPwd-container">
 <aclass="forgetPwd"href="">忘记密码?</a>
 </div>
 <divclass="key-container">
 <divclass="key-item">1</div>
 <divclass="key-item">2</div>
 <divclass="key-item">3</div>
 <divclass="key-item">4</div>
 <divclass="key-item">5</div>
 <divclass="key-item">6</div>
 <divclass="key-item">7</div>
 <divclass="key-item">8</div>
 <divclass="key-item">9</div>
 <divclass="key-item empty"></div>
 <divclass="key-item">0</div>
 <divclass="key-item remove"></div>
 </div>
 </div>
 </div>

CSS部分


.pay-container{ width:7.5rem; height:8rem; background-color:#fbf9fb; position:fixed;z-index:999; overflow:hidden;display:none; }
/* .pay-container-show{transform: translate3d(0, -8.9rem, 0);transition: 0.5s ease;transform: translate3d(0, 0, 0); transition: 0.5s ease;} */
.pay-title{ height:0.96rem; line-height:0.96rem; border-bottom:1pxsolid#b3afaf; text-align:center; color:#070707;
position:relative; font-size:0.36rem;}
.pay-title.pay-title-remove{ width:0.24rem; height:0.24rem; position:absolute; top:0.35rem; left:0.33rem; line-height:0.28rem;
font-size:0.45rem;}
.pay-body{ padding-top:0.56rem;position:relative; height:7rem; box-sizing:border-box;}
.pay-body.input-container{ width:6.74rem; height:0.93rem; border:1pxsolid#ebe8eb; overflow:hidden; border-radius:5px;
background-color:#fff; margin:0auto; display:flex;flex-direction:row;align-items:center; 
flex-wrap:wrap; justify-content:center;align-content:center;}
.pay-body.input-container.input-item{ width:1.1rem; height:0.92rem; display:inline-block; margin:0; border-right:1pxsolid#ebe8eb;
text-align:center; line-height:0.92rem; border-radius:0; }
.pay-body.input-container.input-item:nth-last-child(1){ border-right:0;}
.pay-body.forgetPwd-container{width:6.74rem;margin:0.22remauto0; text-align:right;}
.pay-body.forgetPwd-container.forgetPwd{ color:#52bfff; font-size:0.24rem; }
.pay-body.key-container{ width:100%; height:4.56rem; position:absolute; bottom:0; display:flex;flex-direction:row;align-items:center; 
 flex-wrap:wrap; justify-content:center;align-content:center; }
.pay-body.key-container.key-item{ width:2.47rem; height:1.12rem; line-height:1.12rem; text-align:center; border-right:2pxsolid#f3f3f3;
 border-top:2pxsolid#f3f3f3; font-size:0.66rem; color:#1e1d1f;background-color:#fff;}
.pay-body.key-container.key-item:nth-child(3),
.pay-body.key-container.key-item:nth-child(6),
.pay-body.key-container.key-item:nth-child(9),
.pay-body.key-container.key-item:nth-child(12){ border-right:0;}
.pay-body.key-container.key-item.remove,.pay-body.key-container.key-item.empty{ font-size:0.24rem;background-color:#e6e9f1;}
.pay-body.key-container.key-item.remove{ background:url('../images/pay-remove.png') centerno-repeat#e6e9f1; background-size:.52rem.32rem; }
.pay-body.key-container.selected{ background-color:#e4e8f4;}

核心JS部分


var arr = [];
 var num =0;

 //响应键盘事件
 $('.key-item').on('touchstart', function () {
 $(this).addClass('selected')
 })
 $('.key-item').on('touchend', function () {
 $(this).removeClass('selected')
 })
 $('.key-item').on('click', function () {
 var value =$(this).text();
 var inputItem =$('.layui-m-layercont .input-item');
 if (!$(this).hasClass('remove')) {
 if (num <6) {
 $(inputItem[num]).val(value);
 if (num ==5) {
 var arr = [];
 for (var i =0; i < inputItem.length; i++) {
 arr.push(inputItem[i].value)
 }
 arr =parseInt(arr.join(''));
 if (arr !==123456) {
 layer.open({
 content:'支付密码错误请重新输入!',
 skin:'msg',
 time:2//2秒后自动关闭
 });
 } else {
 layer.open({
 content:'输入正确!',
 skin:'msg',
 time:2//2秒后自动关闭
 });
 }
 num++;
 returnfalse;
 }
 num++;
 }
 } else {
 if (num >0) {
 num--;
 $(inputItem[num]).val('');
 }
 }
 })
