嵌套在JavaScript中的循环 [英] Nested for loops in javascript

问题描述

我现在有下面的嵌套for循环
$ b $ pre $ for（var i = 0; i< = score; i ++）
{
for （var j = 0; j <= i; j ++）
{
var stsc ='< img src =./ images / star.png/>';






$ p $目标是获得stsc变量来显示星号的数量取决于分数变量的数量。



目前，无论分数的值是多少，它都只显示一颗星星。我已经尝试在嵌套循环之外添加stsc无济于事。不管我做什么，它都不会显示除了1星以外的其他东西。

你能指出我的正确方向：如何让它显示正确数量的星星（3分，如果得分是3，0分，如果得分是0等）...

感谢大家

解决方案

  var stsc =; 
 var score = 0; 
 for（var i = 1; i <= score; i ++）
 {
 
 stsc = stsc +'< img src =./ images / star.png />';

I was just wondering if I could get some guidance on an issue I am having with nested for loops in javascript.

I currently have the following nested for loop in place
for (var i = 0; i <= score; i++)
{
    for (var j = 0; j <= i; j++)
    {
        var stsc = '<img src="./images/star.png"/>';
    }
}
The aim is to get the variable stsc to show the number of stars depending on the count of the score variable.

Currently, it will only show 1 star no matter what the value of score is. I have tried adding stsc outside of the nested loop to no avail. No matter what I do it will show nothing other than 1 star.

Could you point me in the right direction as to how to get it to show the correct number of stars (3 stars if score is 3, 0 stars if score is 0 etc...)

Thanks everyone
解决方案
var stsc="";
var score=0;
for (var i = 1; i <= score; i++)
{

        stsc = stsc +'<img src="./images/star.png"/>';
