微信H5转跳微信小程序

//判断当前页面是否在小程序环境中
var ua = window.navigator.userAgent.toLowerCase();
if(ua.match(/MicroMessenger/i) == 'micromessenger'){
	wx.miniProgram.getEnv(function(res) {
		if(res.miniprogram){
			//转跳到小程序
			wx.miniProgram.navigateTo({
	    		url:'/pages/home/pay/index?abc='+123
	    	});
		}
	});
}

封装：

function goMiniProgrom(page){
    var ua = window.navigator.userAgent.toLowerCase();
    if(ua.match(/MicroMessenger/i) == 'micromessenger'){
    	wx.miniProgram.getEnv(function(res) {
    		if(res.miniprogram)
    			wx.miniProgram.navigateTo({url:page});
    	});
    }
}
