Question

var animal = new Array("s","b","c","k","h","g"); 
var animalString =''; 
for(var m=0; m<animal.length; m++){ 
    //console.log(m)
    animalString+= animal[m] +"\n";
    console.log(animalString);
}

Answer 1

您需要做的就是：

var animal = ["s","b","c","k","h","g"];
for (var x = 0; x < animal.length; x++) {
    console.log(animal[x]);
}

没有必要尝试将其放入字符串并将其打印到控制台。无论如何，console.log()在控制台内都有回车符。

Answer 2

只是建议使用加入

var animal = new Array("s","b","c","k","h","g"); 
var animalString = animal.join("\n");

    //console.log(m)
    console.log(animalString);

Answer 3

不确定，但我认为你正在寻找这个：

 var animal = new Array("s","b","c","k","h","g"); 
 var animalString = animal.join().replace(/\,/, '<br/>');

Answer 4

试试这个：

var animal = new Array("s","b","c","k","h","g"); 
var animalString =''; 
for(var m=0; m<animal.length; m++){  
    console.log(animal[m]);
}

Working Fiddle

您不需要任何字符串操作或在此使用+=，因为animal是一个数组对象，正如您所说，您只想要字符串like s b c k h in line by line。因此，for循环逐个执行所有数组项。

我试着逐行打印字符串。
