How Can We Help?
Answer
How many times have you filled out a large XMPro form only for a postback to lose focus on the next input field, and you press backspace which navigates back in history and all your captured information is lost?
Well, here is a small solution to this which can be XMPro system/application wide or page specific you choose.
The solution was found online using jQuery as a library, which you can include into the relevant header pages as needed.
The following piece of jQuery script will allow you to capture the backspace event when called on a where the focus is not on an input field, that is, text box, large text box, etc.
The following script has been included into the Action Item and Process Item “<head>” element of the pages after the jQuery library has been included.
<script type="text/javascript">
$(document).keydown(function(e) {
var element = e.target.nodeName.toLowerCase();
if ((element != 'input' && element != 'textarea') || $(e.target).attr("readonly")) {
if (e.keyCode == 8) {
return false;
}
}
});
</script>
It is pretty straightforward and it is easy enough to display a warning message to the user as well.
Note: This is not limited to any version of XMPro.
