uniapp's own Loading loading effect, message prompt box, and modal box are super simple to implement.

loading box

//显示加载框
uni.showLoading({
                    title: '加载中'
                });

​

//隐藏加载框
uni.hideLoading();

Isn’t it super simple? This is the loading pop-up window that comes with uniapp. You don’t need to download anything. 

Message prompt box (disappears automatically after 2 seconds)

uni.showToast({
		title: '暂未此企业信息'，//显示的文字
        duration: 2000,  //显示多少时间，默认1500毫秒
        icon: "success"  //自定义显示的图标，默认成功success，错误error,加载loading，不显示图标是none
	})


//也可以手动隐藏消息提示框
uni.hideToast();

Modal pop-up window (can have only one OK button, or both OK and Cancel buttons)

uni.showModal({
    title: '提示',  //提示标题
    content: '这是一个模态弹窗',  //提示内容
    showCancel: ture, //是否显示取消按钮，默认ture
    success: function (res) {
        if (res.confirm) {  //confirm为ture，代表点击了确定
            console.log('用户点击确定');
        } else if (res.cancel) {  //cancel为ture，代表点击了取消
            console.log('用户点击取消');
        }
    }
});
