I'm trying to change the color from red to blue but when the red color come its unchangeable
var colorvalue=0;
var sizevalue;
function CG()
{
colorvalue ++;
if (colorvalue==0)
{
document.getElementById("testd").style.color = "blue";
}
else if(colorvalue==1)
{
document.getElementById("testd").style.color = "red";
}
if(colorvalue > 1)
{
colorvalue = 0;
}
}
I already got the answer but how do i have more colors
Thanks for seeing my question and if you do thanks for answering
i edit a bit of your code. try below
var colorvalue=0;
var sizevalue;
function CG()
{
colorvalue ++;
if (colorvalue % 2 == 0)
{
document.getElementById("testd").style.color = "blue";
}
else
{
document.getElementById("testd").style.color = "red";
}
}
Used modulo operation: So if there is a remainder of colorvalue, element will be red.
An alternative method would be to use CSS rather than setting the style directly on the element using JavaScript.
Initialise your text with the color red, and then toggle a blue class on/off using classList.
const test = document.querySelector('.test');
const button = document.querySelector('button');
button.addEventListener('click', handleClick, false);
function handleClick() {
test.classList.toggle('blue');
}.test { color: red; }
.blue { color: blue; }<p class="test">This is a test</p>
<button>Change color</button>
