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

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

You should always consider what the browser will see by the end  In this case  it will see this    lt img src  something  onmouseover  change   ex1      gt    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  amp quot  and  amp apos  as escaped quote and apostrophe  respectively   Armed with this knowledge  use this   document getElementById  something   innerHTML     lt img src  something  onmouseover  change  amp quot ex1 amp quot      gt          That being said  you could just use JavaScript quotes   document getElementById  something   innerHTML     lt img src  something  onmouseover  change   ex1       gt
