Yes you should change the name of your function  Javascript has reserved methods and onclick        click    lt  lt  lt  lt  is one of them so just rename it  add an  s  to the end of it or something  strong text

One possible cause for an item not responding to an event is when the item is overlapped by another  In that case  you may have to set a higher z-index for the item you wish to click on

Two observations    You should write    lt input type  button  value  button text    gt    instead of   lt input type  button  gt button text lt  input gt   You should rename your function  The function click   is already defined on a button  it simulates a click   and gets a higher priority then your method    Note that there are a couple of suggestions here that are plain wrong  and you shouldn t spend to much time on them    Do not use onclick  javascript myfunc     Only use the javascript  prefix inside the href attribute of a hyperlink   lt a href  javascript myfunc    gt   You don t have to end with a semicolon  onclick  foo    and onclick  foo     both work just fine  Event attributes in HTML are not case sensitive  so onclick  onClick and ONCLICK all work  It is common practice to write attributes in lowercase  onclick  note that javascript itself is case sensitive  so if you write document getElementById        onclick        then it must be all lowercase
