The ontouchstart property of the GlobalEventHandlers mixin is an EventHandler that processes touchstart events.

Note: This attribute has not been formally standardized. It is specified in the Touch Events – Level 2 Draft specification and not in Touch Events Recommendation. This attribute is not widely implemented.

Syntax

var startHandler = someElement.ontouchstart;

Return value

startHandler
The touchstart event handler for element someElement.

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>
