step-1	step 2

In instructional or howto pages, it is sometine handy to have a button that copies the box's text directly to the clipboard so it can be pasted into bash command lines.



Step 1) Add HTML:
Example
<input type="text" value="Hello World" id="myInput"> <! text field>
<button onclick="cpyFunc()">Copy text</button> <! button used to copy text>



Step 2) Add JavaScript:
Example
This func is in: /js/cpyTxt.js so add below to <head>
<script type="text/javascript" src="/js/cpyTxt.js"><script>


function myFunction() 
{
  var copyText = document.getElementById("myInput");       // GET TEXT FIELD
  copyText.select();                                    // SELECT TEXT FIELD
  copyText.setSelectionRange(0, 99999);                // FOR MOBILE DEVICES
  navigator.clipboard.writeText(copyText.value);      // CPY TEXT FIELD TEXT 
//  alert("Copied the text: " + copyText.value);        // ALERT COPIED TEXT
}
