Show popup when a specific value is selected in multi select

This example shows how you can use "Javascript to execute on asynchronous postback" to trigger on specific values that get selected in a multi selection listbox.

Define this as Javascript to execute on asynchronous postback:

<script type="text/javascript">
var selectedSoftwareArray = document.getElementById('SelectedSoftwareDiv').innerHTML.split("||").filter(function(c) { return c; });
var selectedSoftwareContent = selectedSoftwareArray.join("||");
if (selectedSoftwareArray.length > 0 && document.showedSelectedSoftwareContent !== selectedSoftwareContent) {
document.showedSelectedSoftwareContent = selectedSoftwareContent;
OpenFancyBox("<h3 style='margin-right: 28px'>Information</h3><ul>" + selectedSoftwareArray.map(function(c) { return "<li>" + c + "</li>"; }) + "</ul>", "html", 500, 250, false, null)
}
</script>

Define this as default answer:

<div style="display:none;" id="SelectedSoftwareDiv">#REPLACE-FORMFIELD-FormName||SelectionList||ColumnWithExtraText#</div>
