how to add spaces between array items javascript
提问by user1876829
I am a beginner at javascript so I appreciate any help/advice given.
我是 javascript 的初学者，所以我感谢您提供的任何帮助/建议。
My issue here is that I'm trying to figure out how to add space between items in the times[] array which holds the values for showtimes for each movie object. I tried to split at the comma (",") but that isn't working. When I tried splitting at ("pm") that worked. I also figured out a way to add space in the showtimes values themselves, but I thought that there must be a better way to go about it. Any thoughts? thanks!
我的问题是我试图弄清楚如何在 times[] 数组中的项目之间添加空间，该数组保存每个电影对象的放映时间值。我试图在逗号（“，”）处拆分，但这不起作用。当我尝试在 ("pm") 拆分时，它起作用了。我还想出了一种方法来增加放映时间值本身的空间，但我认为必须有更好的方法来实现它。有什么想法吗？谢谢！
window.onload = init;
function Movie(title, year, showtimes) {
this.title = title;
this.year = year;
this.showtimes = showtimes;
}
function init() {
var darkKnight = new Movie("The Dark Knight Rises", "2012", ["1pm,", "2pm,", "3pm,"]);
var takeThisWaltz = new Movie ("Take This Waltz", "2012", ["4pm", "5pm","6pm"]);
var watchmen = new Movie("Watchmen", "2009", ["7pm","8pm","9pm"]);
var movieList = [darkKnight, takeThisWaltz, watchmen]
for(var i = 0; i < movieList.length; i++) {
var theObj = movieList[i];
var times = [movieList[i].showtimes]
for(var j = 0; j < times.length; j++) {
var str = times[i];
}
makeResult(); }
function makeResult() {
var list = document.getElementById("movieList");
var li = document.createElement("li");
li.innerHTML = "title: " + movieList[i].title + " year: " + movieList[i].year + " showtimes: " + times[0].toString().split(",");
list.appendChild(li); }
}

the array.joinfunction takes an optional delimiterparameter which will seperate the elements by the delimiter. A simple example:
该array.join函数采用一个可选delimiter参数，该参数将通过分隔符分隔元素。一个简单的例子：
var showtimes = ["1pm", "2pm", "3pm"];
var showtimesAsString = showtimes.join(', '); // gives "1pm, 2pm, 3pm"
