Rebind an event handler that was unbound with .off() method jQuery

I have an element let's call it div1 which I bind an event "click" to so it runs some code on click.
Then I've got another element let's call it div2 when it is clicked it runs this line of code: div1.off('click'); So now the div1 click event handler is unbinded successfully.

This works perfectly well however I would like to "rebind" this div1 click event later on say on a third div click event.

I can't find anywhere how to rebind a click event which I called .off() on.
Does anybody have any idea how I could accomplish this?

What I've tried:

div1.one('click',function() {
    ...some code
});
div2.on('click',function() {
    ...some code
    div1.off('click');
});   
//all good so far
div3.on('click',function() {
    ...some code
    div1.on('click'); //this is the part which is obviously wrong i just put it to show my intentions - this line needs to "rebind" the div1 click event
});    

You should create a function for your one click, for example myfunc your can rebind div1 after you click on div3

<!-- begin snippet: js hide: false console: true babel: false -->

<!-- language: lang-js -->

let div1 = $('#div1');
let div2 = $('#div2');
let div3 = $('#div3');

function myfunc() {
  alert('Haha!')
}

div1.one('click', myfunc);

div2.one('click', function() {
  console.log('off')
  div1.off('click', myfunc);
});
div3.one('click', function() {
  console.log('on')
  div1.on('click', myfunc);
});

<!-- language: lang-html -->

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div id="div1">div1</div>
<div id="div2">div2</div>
<div id="div3">div3</div>

<!-- end snippet -->

And here is example for use bind and unbind in this case:

<!-- begin snippet: js hide: true console: true babel: false -->

<!-- language: lang-js -->

let div1 = $('#div1');
let div2 = $('#div2');
let div3 = $('#div3');

function myfunc() {
  alert('Haha!')
}

div1.one('click', myfunc);

div2.bind('click', function() {
  console.log('off')
  div1.unbind('click');
});
div3.bind('click', function() {
  console.log('on')
  div1.bind('click', myfunc);
});

<!-- language: lang-html -->

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div id="div1">div1</div>
<div id="div2">div2</div>
<div id="div3">div3</div>

<!-- end snippet -->

You can extract the anonymous function defined in div1.on to a normal function which can then be reused. As shown below -

<!-- begin snippet: js hide: false console: true babel: false -->

<!-- language: lang-js -->

var div1 = $("#one")
var div2 = $("#two")
var div3 = $("#three")

div1.one('click',div1Click); //change anonymous function to normal function
div2.on('click',function() {
    console.log('2');
    div1.off('click');
});   
div3.on('click',function() {
    console.log('3');
    div1.on('click', div1Click); 
});    

function div1Click() {
   console.log('1');
}

<!-- language: lang-html -->

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div id="one">  
one
</div>
<div id="two">  
two
</div>
<div id="three">  
three
</div>

<!-- end snippet -->

Another way of turning the click event on and off is to always leave the click capturing in place but make the action dependend on an extra data flag (here:off):

<!-- begin snippet: js hide: false console: true babel: false -->

<!-- language: lang-js -->

$('div[id]').on('click',function() {
 let sw={two:true, three:""}[this.id];
 if (sw===undefined) { // div #one was clicked: do the action:
   if (!this.dataset.off) console.log(this.id); // do the action 
 }
 else $('div#one')[0].dataset.off=sw; // button #two or #three was clicked
});   

<!-- language: lang-css -->

div {cursor:pointer}

<!-- language: lang-html -->

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div id="one">one</div>
<div id="two">two</div>
<div id="three">three</div>

<!-- end snippet -->

I tried a version with {two:true, three:false}, but, unfortunately, the variable sw is turned into a string when saved as dataset.off, so false becomes "false" and becomes truthy. A blank is always falsey.
