I want to change the background-color of my button. This is my code so far:
<script>
function setColor(btn) {
var property = document.getElementById(btn);
if (property.style.backgroundColor == "rgb(127, 255, 0)") {
property.style.backgroundColor = "rgb(255, 0, 0)"
}
else if(property.style.backgroundColor == "rgb(255, 0, 0)")
{
property.style.backgroundColor = ""
}
else {
property.style.backgroundColor = "rgb(127, 255, 0)"
}
}
</script>
<input type="button" id="button" value = "button" onclick="setColor('button')";/>
This works with one button. If I have multiple buttons it only change the first button color. How can I change the color of every button with this JavaScript?
<input type="button" id="button" value = "button" onclick="setColor(this);"/>
js:
function setColor(btn) {
if (btn.style.backgroundColor == "rgb(127, 255, 0)") {
btn.style.backgroundColor = "rgb(255, 0, 0)"
}
else if(btn.style.backgroundColor == "rgb(255, 0, 0)")
{
btn.style.backgroundColor = ""
}
else {
btn.style.backgroundColor = "rgb(127, 255, 0)"
}
}
Try This:-
function setColor(btn) { var property = document.getElementById(btn); if (property.style.backgroundColor == "rgb(127, 255, 0)") { property.style.backgroundColor = "rgb(255, 0, 0)" } else if(property.style.backgroundColor == "rgb(255, 0, 0)") { property.style.backgroundColor = "" } else { property.style.backgroundColor = "rgb(127, 255, 0)" } }
<input type="button" id="button" value = "button" onclick="setColor(this.id);"/>
There is space issue in your script, I removed spaces in rgb colors in script and it is working fine
<script>
function setColor(btn) {
var property = document.getElementById(btn);
if (property.style.backgroundColor == "rgb(127,255,0)") {
property.style.backgroundColor = "rgb(255,0,0)"
}
else if(property.style.backgroundColor == "rgb(255,0,0)")
{
property.style.backgroundColor = ""
}
else {
property.style.backgroundColor = "rgb(127,255,0)"
}
}
</script>
