如何在函数内调用函数

Question

function btn1(){
alert('hello')
}
function btn2(){
alert('anchor') 
}

I want to call the function btn1 and function btn2 separate on clicking the div. As it is shown below.

<div onclick="btn2()" style="position:relative">
<div style="width:50%; float:left; height:50px; background:#ddd">
</div>
<input type="button" value="hello" onclick="btn1()"/>
</div>

Answer 1

If I am getting this right you are probably experiencing bubbling. You might want to read about bubbling and event propagation as it will probably be clearer than what I can try to explain. But to solve your issue you want to take a look at jquery's

event.stopPropagation()

Answer 2

The Click Event of the button bubbles his way up to the div. Take a look here how to prevent this:

I recommend you use addEventListener in favor of inline event handler.
