Question

我想重复代码，直到用户获得no。对。我该怎么做呢？这是代码： -

function getRandomNumber(min,max){
     return Math.floor(Math.random()*(max - min + 1 ))+min;
 }
 randomNumber=(getRandomNumber(1,10));

 input=prompt("Please enter a no. between 1 and 10:","");
 if(input==randomNumber){
     console.log("Good Work");
 }else{
     console.log("not matched");
 }

Answer 1

您可以使用while循环调用＆＃34; break＆＃34;用户输入正确答案后的语句，或者您可以使用如下函数：

function getInput(){
 input=prompt("Please enter a no. between 1 and 10:","");
 if(input==randomNumber){
     console.log("Good Work");
 }else{
     consol.log("not matched");
     getInput(); //Gets the user's input again
 }
}

你去......

在开始之前需要将Found设置为false，否则该函数将只运行一个。在while循环中有函数定义没什么意义，因为它将被创建为全局变量。

var found = false;

function getRandomNumber(min,max) { return Math.floor(Math.random()*(max - min + 1 ))+min; }

while ( found != true ) { 
		
 	var randomNumber = getRandomNumber(1,10);

	console.log('Random Number is..',randomNumber);

 	var input = prompt("Please enter a no. between 1 and 10:","");
 
	 if ( input == randomNumber ) {
	     alert('Well Done')
	     found = true;
	 } else {
	     console.log("not matched");
	 } 
}

如何在用户输入上重复代码？
