How do I call 2 functions from one onclick event? Here's my code

 <input id ="btn" type="button" value="click" onclick="pay() cls()"/>

the two functions being pay() and cls(). Thanks!

Answer 1

You can call the functions from inside another function

<input id ="btn" type="button" value="click" onclick="todo()"/>

function todo(){
pay(); cls();
}

Answer 2

Add semi-colons ; to the end of the function calls in order for them both to work.

 <input id="btn" type="button" value="click" onclick="pay(); cls();"/>

I don't believe the last one is required but hey, might as well add it in for good measure.

Here is a good reference from SitePoint http://reference.sitepoint.com/html/event-attributes/onclick

Answer 3

Binding events from html is NOT recommended. This is recommended way:

document.getElementById('btn').addEventListener('click', function(){
    pay();
    cls();
});

Answer 4

You can create a single function that calls both of those, and then use it in the event.

function myFunction(){
    pay();
    cls();
}

And then, for the button:

<input id="btn" type="button" value="click" onclick="myFunction();"/>

Answer 5

put a semicolon between the two functions as statement terminator.

Answer 6

With jQuery :

jQuery("#btn").on("click",function(event){
    event.preventDefault();
    pay();
    cls();
});
