Clear Value Prompt Selections Using Javascript

Business Case:
User wants a clickable link on the prompt page to clear all prompt selections.

Environment: Cognos 8.4, Report Studio, Javascript, Mozilla Firefox / Internet Explorer


Implementation:
This can be achieved using Javascript.

• Place an HTML item at the end of the prompt page after all the prompts.
• Place the code from the next section into the HTML item.
• You can use a table to position the link on the page.
• When the report is executed, user will see a link "Clear All Selections", which will reset all the prompt selections.

Code:

<script>
var list_prompts = document.getElementsByTagName("select");

function ClearSelections(){
  for (var i=0;i<list_prompts.length;i++)
  {
    list_prompts[i].selectedIndex = -1;
  }
}
</script>

<a href="JavaScript:ClearSelections()">Clear All Selections</a>
