mui 几个基本用法

mui.plusReady(function() {
	plus.screen.lockOrientation("portrait-primary"); //禁止横屏
	document.addEventListener("netchange", wainshow, false);
	function wainshow() {
		if(plus.networkinfo.getCurrentType() == plus.networkinfo.CONNECTION_NONE) {
			mui.toast("网络异常，请检查网络设置！");
			  $('.main-container').remove();
//              $("
刷新
").appendTo('body');
               $('.no_network').show();
               $('.reload').click(function(){
               	   location.reload()
               })
	}
	}
	wainshow();
	//监听安卓返回键
	mui.oldback = mui.back;
	var clickNum = 0;
	mui.back = function(event) {
		clickNum++;
		if(clickNum > 1) {
			plus.runtime.quit();
		} else {
			mui.toast("再按一次退出应用");
		}
		setTimeout(function() {
			clickNum = 0
		}, 1000);
		return false;
	}
