Answer 1

很容易,在地址栏中自己试试:

javascript:alert('“'+new Array(42).join(' ')+'”')

顺便说一下,"在jquery中"应该是"使用jquery"

Answer 2

你可以使用Array.join()这个,像这样:

var myArray = [" "," "," "," "," "," "," "," "," "," "];
var myString = myArray.join(''); //mySting is a string of 10 spaces

您需要传递''to,.join()因为默认的连接符是逗号.
