The proper way to invoke javascript code when clicking a link would be to add an onclick handler:

<a href="#" onclick="myFunction()">LinkText</a>

Although an even "more proper" way would be to get it out of the html all together and add the handler with another javascript when the dom is loaded.

I would avoid inline javascript altogether  and as I mentioned in my comment  I d also probably use  lt input type  button    gt  for this  That being said      lt a href  http   stackoverflow com questions 16337937 how-to-call-javascript-from-a-href  id  mylink  gt Link  lt  a gt      var clickHandler   function          alert  Stuff happens now            if  document addEventListener        document getElementById  mylink   addEventListener  click   clickHandler  false     else       document getElementById  mylink   attachEvent  click   clickHandler         http   jsfiddle net pDp4T 1

If you only want to process a function and not process the href it self  add the return false statement at the end of your function     lt a href     onclick  javascript  function          return false  return false  gt click lt   gt

lt a href  javascript call func     gt     lt  a gt    where the function then has to return false so that the browser doesn t go to another page   But I d recommend to use jQuery  with        click function

User · Answer

JavaScript code is usually called from the onclick event of a link  For example  you could instead do   In Head Section of HTML Document   lt script type  text javascript  gt  function myFunction         script code    lt  script gt    In Body of HTML Document    lt a href     id  mylink  onclick  myFunction    return false  gt Call JavaScript  lt  a gt    Alternatively  you can also attach your function to the link using the links  ID  and HTML DOM or a framework like JQuery   For example   In Head Section of HTML Document   lt script type  text javascript  gt  document getElementById  mylink   onclick   function myFunction       script code    lt  script gt    In Body of HTML Document    lt a href     id  mylink  gt Call JavaScript  lt  a gt
