To stop the user from getting annoyed when the whole text gets selected every time they try to move the caret using their mouse, you should do this using the focus
event, not the click
event. The following will do the job and works around a problem in Chrome that prevents the simplest version (i.e. just calling the textarea's select()
method in a focus
event handler) from working.
jsFiddle: http://jsfiddle.net/NM62A/
Code:
<textarea id="foo">Some text</textarea>
<script type="text/javascript">
var textBox = document.getElementById("foo");
textBox.onfocus = function() {
textBox.select();
// Work around Chrome's little problem
textBox.onmouseup = function() {
// Prevent further mouseup intervention
textBox.onmouseup = null;
return false;
};
};
</script>
jQuery version:
$("#foo").focus(function() {
var $this = $(this);
$this.select();
// Work around Chrome's little problem
$this.mouseup(function() {
// Prevent further mouseup intervention
$this.unbind("mouseup");
return false;
});
});
