uni.showLoading(OBJECT)  
显示 loading 提示框, 需主动调用 [uni.hideLoading][] 才能关闭提示框。

参考文档  
https://uniapp.dcloud.io/api/ui/prompt?id=showmodal

一些参数说明：

test.vue例子

<template>
    	<button @click.stop="isLeave()">点击按钮</button>
    </template>
    <script>
    	export default {
    		data() {
    			return {};
    		},
    		onLoad() {},
    		methods: {
    			isLeave(id) {
    				uni.showLoading({
    				    title: '加载中'
    				});
    			},
    		},
    	}
    </script>
    <style>
    
    </style>

这里需要搭配uni.hideLoading()一起使用  
设置加载两秒之后，隐藏一下加载框

<template>
    	<button @click.stop="isLeave()">点击按钮</button>
    </template>
    <script>
    	export default {
    		data() {
    			return {};
    		},
    		onLoad() {},
    		methods: {
    			isLeave(id) {
    				uni.showLoading({
    				    title: '加载中'
    				});
    				
    				setTimeout(function () {
    				    uni.hideLoading();
    				}, 2000);
    			},
    		},
    	}
    </script>
    <style>
    
    </style>
