onselect Content selection event
Here is our next example:
There is content in the text box. When we select the content of the text box, the event is triggered
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>内容选中事件</title>
</head>
<body>
<input type="text" onselect="onf()" value="php 中文网中文网中文网">
<script type="text/javascript">
function onf(){
alert('您已触发选中内容事件');
}
</script>
</body>
</html>Note: Usually we don’t use this event very much. We use it more for cursor gathering or leaving, as well as some mouse events, such as click events, etc.
