How to change the onclick of a button to another function using JavaScript?

Question

This is my first question I'm asking. Is it possible to change the onclick="change()" to another function like onclick="change1()"

My code is like this:

<a href="#" onclick="changeSrc()" id="a1"><img src="images/transparent-arrow-hi.png" style="position:absolute; top:525px; left:1000px; height:50px; width:50px;" ></a>
<img src="images/keyboard.png" id="pic1">
<img src="images/mouse1.png" id="pic2">
<img src="images/PCstand.png" id="pic3">
<img src="images/monitor.png" id="pic4">

My Javascript is as follows:

<script>
function changeSrc() {
document.getElementById('pic1').src="images/robber1.jpg";
document.getElementById('pic2').src="images/guarding entrance 1.jpg";
document.getElementById('pic3').src="images/Lock.ico";
document.getElementById('pic4').src="images/Number pads.jpg";
}
</script>

This works so far in changing the img src , But I want to click the same button many times to change the img src to others.

So its like this button that when onclick , can call the first function to change the img src and at the same time prepare the onclick to call the second funtion.

Is that even possible?

I can add more code if needed.

you can have counter and every time call your function increase number of counter and select what actions you need.or you can use switch in changeSrc function

<script>
var counter = 0;
function changeSrc() {
 if(counter==0){
    document.getElementById('pic1').src="images/robber1.jpg";
    document.getElementById('pic2').src="images/guarding entrance 1.jpg";
    document.getElementById('pic3').src="images/Lock.ico";
    document.getElementById('pic4').src="images/Number pads.jpg";
}
 if(counter==1){
    document.getElementById('pic1').src="images/robber2.jpg";
    document.getElementById('pic2').src="images/guarding entrance 2.jpg";
    document.getElementById('pic3').src="images/Lock2.ico";
    document.getElementById('pic4').src="images/Number pads2.jpg";
}
    counter++;
}
</script>

if your images have pattern like numbers you can do this

<script>
var counter = 0;
function changeSrc() {
    document.getElementById('pic1').src="images/robber"+counter+".jpg";
    document.getElementById('pic2').src="images/guarding entrance "+counter+".jpg";;
    document.getElementById('pic3').src="images/Lock "+counter+".ico";;
    document.getElementById('pic4').src="images/Number pads"+counter+".jpg";;    
 counter++;
}
</script>

Where in the question has OP mentioned that the image names have same pattern and is distinguished by the appending number 1 and 2 ?

Also what will happen if counter is 3 or 4? I do not think this is an appropriate answer and also why this has been vote up?

@AKA user didn't mentioned any type of image,every type that he likes can insert.

If this is so then for need to mention that for every counter value, not just for counter ==0 or counter==1. Also the OP asked "Is it possible to change the onclick="change()" to another function like onclick="change1()". Not the one you answered.

@AKA its no need.user want to change their image src.its no need to call another functin

You can use this code snippet to dynamically associate and change the onclick function of the element.

function changeSrc(_this){
 //associate function change1 inside changeSrc
 $(_this).attr('onclick','change1(this)');
}

function change1(_this){
//associate function change2 inside change1
  $(_this).attr('onclick','change2(this)');
  console.log('Iniside Change1()')
}

function change2(_this){
//associate function change3 inside change2
  $(_this).attr('onclick','change3(this)');
  console.log('Iniside Change2()')
}

function change3(_this){
  console.log('Iniside Change3()')
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<a href="#" onclick="changeSrc(this)" id="a1"><img src="images/transparent-arrow-hi.png" style="position:absolute; top:525px; left:1000px; height:50px; width:50px;" >click</a>
