Javascript Function: array_search()
Was writing some javascript for a friend and developed these simple functions for searching javascript arrays.
Becomes pretty useful when your working with select html boxes and arrays in javascript.
function array_search (array,val) { for (var i = 0; i < array.length; i++) { if (array[i] == val) { return i; } } return false; }; function array_search_key(array,num) { if (array[num]) return true; return false; };
An example of the usage:
var myArray = [ 10, 20, 30, 40, 50, 60 ]; alert( array_search( myArray, 30 ) ); // Output: 2
Keep in mind that arrays in most langauges start from 0.
for_example( myArray[0] ); // Outputs 10
Hope this function comes in use some day.
