weui 多列选择器实现，在单列选择器上多加一列，样式weui中已经实现

demo：实现选择时间的两列选择器

1.html

<a class="weui-cell weui-cell_access font14" href="javascript:;" onclick="ShowTimePicker()">
						<div class="weui-cell__hd">
							<img src="../images/time.png" height="12" class="disblock" />
						</div>
						<div class="weui-cell__bd">
							<p>服务时间</p>
						</div>
						<div class="weui-cell__ft public-color">
							<input class="weui-input text-right" readonly="readonly" type="text" placeholder="请选择服务时间" />
						</div>
					</a>

2.js

function ShowTimePicker() {
	var hours = [];
	var minites = [];
	if(!hours.length) {
		for(var i = 0; i < 19; i++) {
			hours.push({
				label: ('' + i).length === 1 ? '0' + i + "时" : '' + i + "时",
				value: i
			});
		}
	}
	if(!minites.length) {
		for(var j = 0; j < 60; j++) {
			minites.push({
				label: ('' + j).length === 1 ? +j + "分" : '' + j + "分",
				value: j
			});
		}
	}
	weui.picker(hours, minites, {
		defaultValue: [new Date().getHours() + 1, 0],
		onConfirm: function(result) {
			var timeend = result[1] < 10 ? ("0" + result[1]) : result[1];
			var time = result[0] + ':' + timeend;
		}
	});
}

效果：

同理可实现三列甚至多列选择器
