space between words in JS
提问by Nave Tseva
I have this JS code:
我有这个JS代码：
function myPopUp()
{
var y;
var name=prompt("Please enter your name"," ???? ?? ???");
if (name!=null)
{
y= ' How are you today?';
document.getElementById("popup").innerHTML = y;
var x="";
var time=new Date().getHours();
if (time<20)
{
x="Have a nice day" + name + '!';
}
else
{
x=' Great evening '+ name +' ! ';
}
document.getElementById("demo").innerText = x ;
}
}
with this HTML code:
使用此 HTML 代码：
<body>
<button onclick="myPopUp()" >??? ???</button>
<p id="demo"></p>
<p id="popup"></p>
</body>
My question: When someone write their name there is no space between the words? How do I put a space between words in JS?
我的问题：当有人写他们的名字时，单词之间没有空格？如何在JS中的单词之间放置空格？
Thank you.
谢谢你。

In HTML, extra white space is collapsed to a single space (ASCII 32) character.
在 HTML 中，多余的空白被折叠为单个空格 (ASCII 32) 字符。
If you MUST force a space, use the html identity which is a non-breaking space.
如果您必须强制使用空格，请使用 不间断空格的 html 标识。
Better yet, use CSS to put margins around your element and make the spacing visual.
更好的是，使用 CSS 在元素周围放置边距并使间距可视化。

Looks like you just need a space after "day," so try this:
看起来你只需要在“一天”之后一个空格，所以试试这个：
x="Have a nice day " + name + '!';
