javascript - How to select "a" tag has specific file type in href using jQuery? -


i targeting links contain various file types in jquery using:

jquery('a[href$=".pdf"], a[href$=".doc"], a[href$=".docx"], a[href$=".ppt"], a[href$=".pptx"], a[href$=".xls"], a[href$=".slxs"], a[href$=".epub"], a[href$=".odp"], a[href$=".ods"], a[href$=".txt"], a[href$=".rtf"]').before('<span class="glyphicon glyphicon-file"></span> ');

firstly, there way of reducing repetition? e.g.

jquery('a[href$=".pdf|.doc|.docx"])

and secondly, there way target different cases file extensions e.g. pdf, pdf , pdf?

you can filter selected element using .filter(). in filter function check extension using regex in string.prototype.match().

$("a").filter(function(){    return $(this).attr("href").match(/\.(pdf|doc|docx|ppt|pptx|xls|slxs|epub|odp|ods|txt|rtf)$/i); }).before("some html"); 

$("a").filter(function(){    return $(this).attr("href").match(/\.(pdf|doc|docx|ppt|pptx|xls|slxs|epub|odp|ods|txt|rtf)$/i);  }).css("color", "red")
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>  <a href="file.pdf">pdf</a>  <a href="file.doc">doc</a>  <a href="file.html">html</a>  <a href="file.docx">docx</a>  <a href="file.ppt">ppt</a>  <a href="file.php">php</a>  <a href="file.slxs">slxs</a>  <a href="file.txt">txt</a>

note i flag @ end of regex match case insensitive.
