Answer 1

您可以使用“加入数组”技巧重复一个字符串，并使用Math.random()获取一个随机数，以及使用任何按位运算将数字四舍五入，因此一种简洁的方法是：

Array(Math.random() * 11 + 1 | 0).join('0')

Answer 2

// Function simulating PHP str_repeat()
function str_repeat(str, multiplier) {
  return new Array(multiplier + 1).join(str);
}

// Generate the string
var number_of_times = Math.floor(Math.random()*11);
var my_repeated_string = str_repeat('0', number_of_times);

// Put the string inside a HTML element
document.getElementById("your_element_id").innerHTML = my_repeated_string;

Answer 3

Ok here goes...

var $yourString;

for(var i=0;i<10;i++) { 
  $yourString += "0"; 
}

Is that what you are trying to do? Your comment on the other answer says you want to generat 0 many times, not random number. This will do that and build it into one string. Not sure why you would do that.

Hope this helps!

Answer 4

I like the array join hack (upvoted it), but here's a functional way:

function str_repeat (str, n) {
    n = parseInt(n, 10);

    if (--n) {
        str += str_repeat(str, n);
    }

    return str;
}


console.log(str_repeat('0', 10));  // 0000000000

Answer 5

Reusable parts:

function GetRandom(min, max)
{
    return Math.round(Math.random() * (max - min)) + min;
}

function CreateRandomRepeat(text, min, max)
{
    var repeat = [];

    for (var index = 0; index < GetRandom(min, max); index++)
    {
        repeat[index] = text;
    }

    return repeat.join('');
}

Solution:

CreateRandomRepeat('0', 1, 10);
