.innerHTML <br> breaking
提问by Kevin Banas
Why is this breaking? I've not used .innerHTML correctly before and don't know why this would be wrong.
为什么会这样断？我以前没有正确使用 .innerHTML，不知道为什么会出错。
function asdf() {
document.getElementById("qwerty").innerHTML="A<br>
B<br>
C<br>
D<br>";
}

You have to escape new-lines in JavaScript string-literals:
您必须在 JavaScript 字符串文字中转义换行符：
function asdf() {
document.getElementById("qwerty").innerHTML="A<br>\
B<br>\
C<br>\
D<br>";
}
Though you could, potentially more-easily, simply insert newlines in the string itself:
尽管您可以更轻松地在字符串本身中插入换行符：
function asdf() {
document.getElementById("qwerty").innerHTML = "A<br>\nB<br>\nC<br>\nD<br>";
}
回答by SLaks
Javascript string literals cannot contain newlines.
Javascript 字符串文字不能包含换行符。
You can escape the newlines with backslashes:
您可以使用反斜杠转义换行符：
var myString = "a\
b";
