but returning error result.push not function. how push value on variable , trying alert result variable. please solve query.
thanks.

you should initialize result variable

var result = []; 

so final code be:

var region = "rajkot,jamnagar,surat"; var result = []; var array = region.split(','); (var i=0; i<array.length; i++ ){    alert(array[i]);    result.push(array[i]); } 

but split() returns array, for might unnecessary, unless wish business logic elements of array before adding them results.
