Overview: There is a Button on my webage, its a single button. When I click this button, it should call function X. If I click this button a second time, it should call function Y. Basically, this is an ON and OFF switch. this button calls a function via onclick="function X". the same onclick needs to call function Y if clicked again. I hope I made that clear.
It cannot be 2 seperate buttons. thats too easy. does anyone have any ideas ? the only flexibily I have in terms of languages is html, javacript and css. any ideas welcome.
You don't need multiple functions. Just use a boolean to toggle between 2 different parts of code.
var toggle = true;
function functionX(){
if(toggle){
// Logic for the first click
} else {
// Logic for the other click
}
toggle = !toggle; // change the toggle for the next time the button's clicked.
}
There are a few ways to do this:
html
<button id="a" onclick="a()">Test</button>
<button id="b" onclick="b()" style="hidden">Test</button>
css
.hidden {
display: none;
}
js
function a() {
var buttonA = document.getElementById('a');
var buttonB = document.getElementById('b');
buttonA.classList.add('hidden');
buttonB.classList.remove('hidden');
}
function b() {
var buttonA = document.getElementById('a');
var buttonB = document.getElementById('b');
buttonB.classList.add('hidden');
buttonA.classList.remove('hidden');
}
html
<button onclick="x()">Test</button>
js
var clicked = 'b'; //initial state
function x() {
switch(clicked) {
case 'a':
clicked = 'a';
a();
break;
case 'b':
clicked = 'b';
b();
break;
default: throw 'unknown state';
}
}
function a() {
//something
}
function b() {
//something
}
html
<button id="x">Test</button>
js
$(document).ready(function() {
$('#x').click(a());
});
function a() {
//do something then..
$('#x').click(b);
}
function b() {
//do something then..
$('#x').click(a);
}
try this code
var i = 0; function fun() { if (i == 0) { funX(); i = 1; } else { funY(); i = 0; } } function funX() { console.log('x'); } function funY() { console.log('y'); }
<button id="test" onclick="fun()">Click</button>
