How do I automatically select the text that is i开发者_JAVA技巧n a textarea when the page loads using JavaScript?
JSFiddle Demo
You can do it this way:
HTML:
<textarea id='mytext'>Testing 1 2 3</textarea>
JavaScript:
window.onload = document.getElementById('mytext').select();
Where mytext is your textarea
Try this:
Textarea:
<textarea rows="3" id="txtarea" style="width:200px" >This text you can select all by clicking here </textarea>
<script type="text/javascript">
document.getElementById('txtarea').focus();
document.getElementById('txtarea').select();
</script>
In the onload function of your body, place a call to the select function of your textarea...
HTML:
<body onload='highlightTextArea()'>
<textarea id='myTextArea'>Hello World!</textarea>
</body>
JS:
var highlightTextArea = function (){
document.getElementById('myTextArea').select();
}
this is the answer posted on the dupe:
$(document).ready(function() {
$('#text-area-id').focus();
});
