Javascript计数器功能 [英] Javascript Counter Function
本文介绍了Javascript计数器功能的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我正在尝试编写一个名为''count''的JS函数,它将接受两个整数参数,然后返回一个字符串,列出两个参数之间的所有数字。例如,如果我调用count(0,10),那么程序应该显示0,1,2,3等,最后是10.但是,经过大量的尝试,我只成功显示了第二个参数(10)。任何指导将不胜感激。
函数计数(num1,num2)
{
var strCou ='''';
for(count = num1; count< = num2; count ++)
{
strCou = count;
}
console.log(strCou);
}
count(0,10);
解决方案
函数计数(num1,num2)
{
var strCou = ' ';
for (count = num1; count < = num2; count ++)
{
strCou + = count;
}
console.log(strCou);
}
count( 0 , 10 );
I am trying to write a JS function called ''count'' which will accept two integer parameters and then return a string listing all of the numbers between the two parameters. For example, if I called count(0,10) then the program should display 0,1,2,3 etc and finally 10. However, after extensive trying, I have only succeeded in displaying the second parameter (10). Any guideance would be appreciated.
function count(num1, num2) { var strCou = ''''; for(count = num1; count <= num2; count++) { strCou = count; } console.log(strCou); } count(0,10);
解决方案
function count(num1, num2) { var strCou = ''; for(count = num1; count <= num2; count++) { strCou += count; } console.log(strCou); } count(0,10);
