Use Slider to Change Image CSS Filter with Javascript

Question

I'm trying to change the css filter (hue-rotate to be exact) on a png by using a slider input. I keep getting "-webkit-filter:hue-rotate( undefined deg)"

Thanks for your help!

Here's my code:

 function hueFunction(hueVal) { var setAs = hueVal + "deg" document.getElementById("lgImage").setAttribute("style", "-webkit-filter:hue-rotate(" + setAs + ")") } 

 <input type="range" data-default="0" value="0" min="0" max="360" step="1" id="hue-rotate" oninput="hueFunction(this.hueVal)"> <br/> <img src="https://campstoregear.com/wp-content/uploads/2017/09/summer-camp-2018-apparel-design-CD1816-Primary.png" id="lgImage"> 

Answer 1

Change oninput="hueFunction(this.hueVal)" to oninput="hueFunction(this.value)"

 function hueFunction(hueVal) { var setAs = hueVal + "deg" document.getElementById("lgImage").setAttribute("style", "-webkit-filter:hue-rotate(" + setAs + ")") } 

 <input type="range" data-default="0" value="0" min="0" max="360" step="1" id="hue-rotate" oninput="hueFunction(this.value)"> <br/> <img src="https://campstoregear.com/wp-content/uploads/2017/09/summer-camp-2018-apparel-design-CD1816-Primary.png" id="lgImage">
