简单数字键盘

好久没有写博客了，最近有个需求关于数字键盘的，找了下网上的感觉有点重，太复杂！自己随手写了个符合自己需求的比较简单的，分享一下！希望大家指正

number.spiner.js

/**

	}  
	win['Team777NumberSpiner']=NumberSpiner;
})(window);

 基本css样式：

less版

.number-spinner{
	.posa;
	z-index:3;
//	.p(3px);
	.number-box{
		.p(2px);
		.bc(@white);
		.oh;
		li{
			.w(33.3%);
			.fl;
			cursor:pointer;
//			.h(45);
			.lh(45);
			.number{
				.m(2px);
				.yellow-style;
				.tc;
			}
		}
	}
}

 css版

.number-spinner {
  position: absolute;
  z-index: 3;
}
.number-spinner .number-box {
  padding: 2px;
  background-color: #ffffff;
  overflow: hidden;
}
.number-spinner .number-box li {
  width: 33.3%;
  float: left;
  cursor: pointer;
  line-height: 45px;
}
.number-spinner .number-box li .number {
  margin: 2px;
  background: #FDA24D;
  /* 一些不支持背景渐变的浏览器 */
  background: -moz-linear-gradient(top, #fda24d, #fdda6f);
  background: -webkit-gradient(linear, 0 0, 0 bottom, from(#fda24d), to(#fdda6f));
  background: -o-linear-gradient(top, #fda24d, #fdda6f);
  border-radius: 5px;
  text-align: center;
}

引用处理

由于是用angularjs处理  

<input type="text" class="input-txt" ng-model="orderManager.mdseCode" ng-click="orderManager.getNumber($event)">

$scope.orderManager.getNumber=function($event,type){	
     Team777NumberSpiner.init($event.target,type);
};
