If you really just want to append a space character, use the following:
如果您真的只想附加一个空格字符，请使用以下命令：
div.innerHTML += ' ';
or
或者
div.innerHTML += ' ';

对于 HTML 实体。

Try using this:
尝试使用这个：
myElement.appendChild( document.createTextNode( '\u00A0' ) );
If you want/need more spaces, use several \u00A0e.g.:
如果您想要/需要更多空间，请使用多个\u00A0例如：
myElement.appendChild( document.createTextNode( '\u00A0\u00A0' ) );
This one:
这个：
document.createEntityReference('nbsp');
doesn't work all browsers, so avoid it.
不适用于所有浏览器，因此请避免使用它。

You're looking for document.createTextNode(' ')I believe.
你在找document.createTextNode(' ')我相信。
This can only be used for plain text though, not for entities.
但这只能用于纯文本，不能用于实体。

document.getElementById("mydiv").innerHTML +="!";
works (I use exclaimation for immediacy of results, replace with what you wish.

you could do that as follows; but if you want some empty space maybe css would work better (margin, padding, ...)
你可以这样做；但如果你想要一些空白空间，也许 css 会更好（边距，填充，...）
var span = document.createElement("span");
span.innerHTML = " "; // (if this doesn't work try " ")
anyElement.appendChild(span); // make sure anyElement actually points to a DOM element

This could help!!
这可能有帮助！！
var blank = document.createElement("br");
/*this creates a br(for a break) element dynamically */
myElement.appendChild(blank);
/* myElement could be any HTML element like div ,
span , img etc created dynamically ,
var myElement = document.createElement("your element") */
You could append br as many times you want to get that many blank lines.
您可以多次附加 br 以获得那么多空行。
