Element id by javascript

Question

I am using document.getElementsByTagName("input") to get all the input elements in my form.While iterating through them I need to find an element with a particular id say "data" and process it.How can search in the elements such that an element of a particular id exists.

If there's some reason you don't want to do:

var el = document.getElementById('data');

...you could iterate over the collection:

var inputs = document.getElementsByTagName("input"), 
    len = inputs.length,
    el;

while( len-- ) {
    if( inputs[ len ].id === 'data' ) {  // Test the "id" property.
        el = inputs[ len ];              // If a match, grab that one,
        break;                           //     and break the loop.
    }
}

EDIT: Fixed error where I had el = inputs[ len ].id; instead of el = inputs[ len ];

You can just use:

document.getElementById("data")

Cause id's are unique.
