Detect mousemove when over an iframe?

August 4, 2023 by Tarik

If your target isn’t Opera 9 or lower and IE 9 or lower you can use css attribute pointer-events: none. I found it the best way just to ignore iframe. I add class with this attribute to iframe in onMouseDown event and remove in onMouseUp event. Works perfect for me.

clearRect function doesn’t clear the canvas

You should use “beginPath()“. That is it. function lineDraw() { var canvas=document.getElementById(“myCanvas”); var context=canvas.getContext(“2d”); context.clearRect(0, 0, context.width,context.height); context.beginPath();//ADD THIS LINE!<<<<<<<<<<<<< context.moveTo(0,0); context.lineTo(event.clientX,event.clientY); context.stroke(); }
