JS - jQuery inarray ignoreCase() and contains()

well, I am more of a PHP person, and my JS skills are close to none when it comes to any JS other than simple design related operations , so excuse me if I am asking the obvious .

the following operations would be a breeze in PHP (and might also be in JS - but I am fighting with unfamiliar syntax here ...)

It is some sort of input validation

var ar = ["BRS201103-0783-CT-S", "MAGIC WORD", "magic", "Words", "Magic-Word"];

    jQuery(document).ready(function() {
        jQuery("form#searchreport").submit(function() {
        if (jQuery.inArray(jQuery("input:first").val(), ar) != -1){ 
                jQuery("#contentresults").delay(800).show("slow");

            return false;
          }

This question has 2 parts .

  • 1 - how can I make it possible for the array to be case insensitive ?

E.g. - BRS201103-0783-CT-S will give the same result as brs201103-0783-ct-s AND Brs201103-0783-CT-s or MAGIC magic Magic MaGIc

basically i need something like ignoreCase() for array , but I could not find any reference to that in jQuery nor JS...

I tried toLowerCase() - but It is not working on the array (ittirating??) and also, would it resolve the mixed case ?

  • 2 - How can I make the function to recognize only parts or combinations of the elements ?

E.g. - if one types only "word" , I would like it to pass as "words" , and also if someone types "some word" it should pass (containing "word" )

To check if an array contains an element, case-insensitive, I used this code:

    ret = $.grep( array, function (n,i) {
        return ( n && n.toLowerCase().indexOf(elem.toLowerCase())!=-1 );
    }) ;

Here is a fiddle to play with array match case insensitive
