How do I escape a single quote in JavaScript

Question

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 listeners instead  I highly recommend that you utilize jQuery for your project and use their syntax to manage event listeners over using DOM   QUESTION  Okay  I am basically doing this   document getElementById  something   innerHTML     lt img src  something  onmouseover  change   ex1       gt      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    lt img src  something  onmouseover  change  ex1      gt    Escaping isn t working for me   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:

<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.

The truth is, HTML does not use \ for an escape character. But it does recognise " and ' as escaped quote and apostrophe, respectively.

Armed with this knowledge, use this:

document.getElementById("something").innerHTML = "<img src='something' onmouseover='change(&quot;ex1&quot;)' />";

... That being said, you could just use JavaScript quotes:

document.getElementById("something").innerHTML = "<img src='something' onmouseover='change(\"ex1\")' />";

The answer here is very simple   You re already containing it in double quotes  so there s no need to escape it with     If you want to escape single quotes in a single quote string   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   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   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
