Setting maxlength of textbox with JavaScript or jQuery

I want to change the maxlength of a textbox with JavaScript or jQuery: I tried the following but it didn't seem to help:

var a = document.getElementsByTagName('input');
for(var i=0; i<a.length; i++) {
    if((a[i].type!= 'radio')||(a[i].type!= 'checkbox'))
        a[i].maxlength = 5;
}
document.getElementsByTagName('input')[1].maxlength="3";

$().ready(function()
{
    $("#inputID").maxlength(6);
});

What am I doing wrong?

Not sure what you are trying to accomplish on your first few lines but you can try this:

$(document).ready(function()
{
    $("#ms_num").attr('maxlength','6');
});
