很简单,请在地址栏中自行尝试:

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

顺便说一下,“在jquery中”应该是“使用jquery”

您可以使用Array.join(),如下所示:

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

您需要将''传递给.join(),因为默认的连接符是逗号。

你可以使用join。 例如:

var x = ['a', 'b', 'c', 'd'];
var y = x.join('');
