Inline JavaScript onclick function

you can use Self-Executing Anonymous Functions. this code will work:

<a href="#" onClick="(function(){
    alert('Hey i am calling');
    return false;
})();return false;">click here</a>

see JSfiddle


This should work

 <a href="#" onclick="function hi(){alert('Hi!')};hi()">click</a>

You may inline any javascript inside the onclick as if you were assigning the method through javascript. I think is just a matter of making code cleaner keeping your js inside a script block


This isn't really recommended, but you can do it all inline like so:

<a href="#" onClick="function test(){ /* Do something */  } test(); return false;"></a>

But I can't think of any situations off hand where this would be better than writing the function somewhere else and invoking it onClick.


Based on the answer that @Mukund Kumar gave here's a version that passes the event argument to the anonymous function:

<a href="#" onClick="(function(e){
    console.log(e);
    alert('Hey i am calling');
    return false;
})(arguments[0]);return false;">click here</a>
