How to re-focus to a text field when focus is lost on a HTML form?
- by Horace Ho
There is only one text field on a HTML form. Users input some text, press Enter, submit the form, and the form is reloaded. The main use is barcode reading. I use the following code to set the focus to the text field:
<script language="javascript">
<!--
document.getElementById("#{id}").focus()
//-->
</script>
It works most of the time (if nobody touches the screen/mouse/keyboard).
However, when the user click somewhere outside the field within the browser window (the white empty space), the cursor is gone. One a single field HTML form, how can I prevent the cursor from getting lost? Or, how to re-focus the cursor inside the field after the cursor is lost? thx!
