Return value

Example

This example shows two ways to use ontouchstart to set an element's touchstart event handler.

<html>
<script>
function startTouch(ev) {
  // Process the event
}
function init() {
  let el = document.getElementById('target1');
  el.ontouchstart = startTouch;
}
</script>

<body onload="init();">
  <div id="target1"> Touch me ... </div>
  <div id="target2" ontouchstart="startTouch(event)"> Touch me ... </div>
</body>
</html>
