Wait for the end of the network request in the uniapp Onshow method before executing the subsequent code content

The idea is to use vue Of watch The listener ：
After the network request is completed , change watch Listen for the value , Let it trigger subsequent actions .
Here is the sample code ：

export default {
    
	data(){
    
		return {
    
			isInit: 0 // Custom variable , It is used to trigger the operation after the network request 
		}
	},
	watch: {
    
		//  Listen for custom variables , When the duty becomes 1 when ( After the network request is completed ), Follow up .
		//  Among them, formal parameters newVal On behalf of the variable isInit Changed value ,oldVal On behalf of the variable isInit The value before the change 
		isInit: function(newVal, oldVal) {
    
			if(newVal == 1) {
    
				//  The operation method after the network request is completed 
				this.afterInit()
			}
		}
	},
	
	onShow() {
    
		//  Network request method executed 
		this.networkRequest()
	},
	methods: {
    
		networkRequest() {
    
			//  Make a network request here 
			....
			//  After the request is completed, the custom variable isInit Change it to 1, The listener is triggered watch Medium isInit Method 
			this.isInit = 1
		},
		afterInit() {
    
			//  Here is to wait for the completion of the network request before executing the subsequent code 
		}
	}
}
