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.
