JS method to select text in TextArea_javascript skills

The example in this article describes the method of selecting text in TextArea using JS. Share it with everyone for your reference. The specific implementation method is as follows:

<script type="text/javascript">
  function select_field(id){
    document.getElementById(id).focus();
    document.getElementById(id).select();
  }
  function init(){
    select_field('text1');
  }
  onload=init;
</script>
<form>
This field gets selected onload:<br/>
<input type="text" name="text1" id="text1" value="some text" />
<br/>
<textarea name="textarea1" id="textarea1" rows="9" cols="50" wrap="off">Some long
content in here.
abcd efgh abcd efgh abcd efgh
abcd efgh abcd efgh abcd efgh
abcd efgh abcd efgh abcd efgh
</textarea>
<br/>
<input type="button" value="Select text" onclick="select_field('textarea1')">
</form>

I hope this article will be helpful to everyone’s JavaScript programming design.
