JavaScript Javascript find and higlight text between [quote][/quote] within textarea javascript find and highlight text on page,javascript window.find

I have this HTML code with pre-written message. My goal is to highlight text between [quote] [/quote] in a yellow background once I focus/click on the text area.

<textarea>
This is a test message.

[quote]Wise man said he is wise.[/quote] There could be more quotes too:

[quote]this is second quote [/quote]

He is correct.
</textarea>

Is it possible to do it with pure Javascript? I think it should be something like:

textarea onfocus="function()">

  • find text between [quote][/quote]
  • apply yellow background to found text: background Color='#ffc'

....

(and if there is no [quote] [/quote] found then it should do nothing, ie. no warnings).
