php - onclick of multiple checbox in javascript -

my code follows

<script> function search() { var bed = document.getelmentbyid("bed").value; alert(bed); } </script> <input type="checkbox" id="bed" name="bed" value="1" onclick="search()"/>1 bhk <br/> <input type="checkbox" id="bed" name="bed" value="2" onclick="search()"/>2 bhk <br/> <input type="checkbox" id="bed" name="bed" value="3" onclick="search()"/>3 bhk <br/> <input type="checkbox" id="bed" name="bed" value="4" onclick="search()"/>4 bhk <br/> <input type="checkbox" id="bed" name="bed" value="5" onclick="search()"/>5 bhk <br/>

when click on of checkbox first value.

all checkboxes have same id. means document.getelementbyid("bed") homecoming first element id "bed". in case <input type="checkbox" id="bed" name="bed" value="1" onclick="search()"/>. seek giving other different id's or said in comment, set in array.
