How do I escape a single quote ( ' ) in JavaScript?
提问by Matthew
UPDATE:I want to give an updated answer to this question. First, let me state if you're attempting to accomplish what I have below, I recommend that you manage events by adding event listenersinstead. I highly recommend that you utilize jQueryfor your project and use their syntax to manage event listenersover using DOM.
更新：我想对这个问题给出更新的答案。首先，让我说明一下，如果您正在尝试完成我在下面所做的工作，我建议您改为通过添加事件侦听器来管理事件。我强烈建议你在你的项目中使用jQuery，并使用它们的语法来管理事件监听器而不是使用 DOM。
QUESTION
题
Okay, I am basically doing this:
好的，我基本上是这样做的：
document.getElementById("something").innerHTML = "<img src='something' onmouseover='change(\'ex1\')' />";
I don't want double quotes (") where I put the \'. I only want a single quote, so I am trying to not make it put a double when it is used. I am trying to reach this in the final outcome.
我不想在我放 \' 的地方使用双引号 (")。我只想要一个单引号，所以我试图在使用它时不让它加双引号。我试图在最终结果中达到这一点.
<img src="something" onmouseover="change('ex1')" />
Escaping isn't working for me.
逃避对我不起作用。
My marked answer works fine, however, the cleaner (and more professional-looking way, IMO) is loganfsmyth's answer.

You should always consider what the browser will see by the end. In this case, it will see this:
您应该始终考虑浏览器最终会看到什么。在这种情况下，它会看到：
<img src='something' onmouseover='change(' ex1')' />
In other words, the "onmouseover" attribute is just change(, and there's another "attribute" called ex1')'with no value.
换句话说，“onmouseover”属性只是change(，还有另一个ex1')'没有值的“属性” 。
The truth is, HTML does not use \for an escape character. But it does recognise "and 'as escaped quote and apostrophe, respectively.
事实是，HTML 不\用于转义字符。但它确实分别识别"和'作为转义引号和撇号。
Armed with this knowledge, use this:
有了这些知识，使用这个：
document.getElementById("something").innerHTML = "<img src='something' onmouseover='change("ex1")' />";
... That being said, you could just use JavaScript quotes:
...话虽如此，您可以只使用 JavaScript 引号：
document.getElementById("something").innerHTML = "<img src='something' onmouseover='change(\"ex1\")' />";

The answer here is very simple:
这里的答案很简单：
You're already containing it in double quotes, so there's no need to escape it with \.
您已经将它包含在双引号中，因此无需使用\.
If you want to escape single quotes in a single quote string:
如果要在单引号字符串中转义单引号：
var string = 'this isn\'t a double quoted string';
var string = "this isn\"t a single quoted string";
// ^ ^ same types, hence we need to escape it with a backslash
or if you want to escape \', you can escape the bashslash to \\and the quote to \'like so:
或者如果你想转义\'，你可以转义 bashslash\\和引用\'这样的：
var string = 'this isn\\'t a double quoted string';
// vvvv
// \ ' (the escaped characters)
However, if you contain the string with a different quote type, you don't need to escape:
但是，如果包含具有不同引号类型的字符串，则无需转义：
var string = 'this isn"t a double quoted string';
var string = "this isn't a single quoted string";
// ^ ^ different types, hence we don't need escaping

You can escape a 'in JavaScript like \'
你可以'像在 JavaScript 中转义 a\'

Since the values are actually inside of an HTML attribute, you should use '
由于值实际上在 HTML 属性内，您应该使用 '
"<img src='something' onmouseover='change('ex1')' />";
回答by David Tayfun
document.getElementById("something").innerHTML = "<img src=\"something\" onmouseover=\"change('ex1')\" />";
OR
或者
document.getElementById("something").innerHTML = '<img src="something" onmouseover="change(\'ex1\')" />';
It should be working...
它应该工作...
