how to find out a character in an array?

[ammuhere]

i have an array elmlist=["0","0.1","1"]

so i need to find out if there is any value which includes "."

using array.contains and indexOf will return true only if the value itself completely match with the searchstring.

var elmlist=["0","0.1","1"]

function findInArray(arr, str) {
    for(var i=0;i<arr.length;i++) {
        if(arr[i].indexOf(str) != -1) {
            return true;
            //Use the following if you want to return the value
            //return arr[i];
        }
    }
    return false;
}

alert(findInArray(elmlist, "."));
alert(findInArray(elmlist, "-"));

Or something like this:

<script type="text/javascript">

	var elmlist = ['0', '0.1', '1'];

	alert(

		elmlist.join('').indexOf('.') > -1 ? 'FOUND' : 'NOT FOUND'

	);

</script>

Or simply the boolean /\./.test(elmlist.toString()) !

var elmlist=["0","0.1","1"]
alert(/\./.test(elmlist.toString()))

// To find the range 
var elmstr=elmlist.toString(),range=-1;
if (/\./.test(elmstr)) range=elmstr.replace(/\.[\d,\+\-]+/,'').split(',').length-1;
alert(range);
