jQuery - If first element has class then Function -

I want to add a piece of code to affect all my pages.

Correct attribute ('id') == 'filter option') ($ ('$ container & gt; div: first') {$ ('# container'). Prepaid ('& lt; Div class = "banner">

& gt; ';);}

Output:

Example , if the container looks like this:

  & lt; Div id = "container" & gt; div class = "current banner"> 
 
 
 
 & lt ; / Div & gt;  

Nothing will be like the first filter in the filter I have hit a collision now because I have something that looks like this banner

  & lt; div id = "container" & Gt; A class = "current banner" href = "#" & gt; & lt; / a & gt; & lt; div id = "filterOptions" & gt; & lt; div & Gt; & lt; / Div & gt;  

This will be essentially a double banner that I want to save. Because it's an anchor instead of a div.

So my question is how do I target all elements instead of targeting div: first ?

Something like this ...

if ('$' ('# container') Anyone : first '). Attr (' id ') ==' filterOptions') {...}
