Description:

When using a value prompt with Multi-select, it automatically displays "Select all" and "Deselect all" at the bottom right.  This document describes a technique for removing these links from the bottom of a multi select value prompt.

Solution:

The following script will remove these links from a Value Prompt named RemoveSelectAllDeSelectAll

<script>
    var a = document.getElementsByTagName("A");
    for(var i=0;i<a.length;i++){
alert(a.href.split("#")[0]);
        if(a.href.split("#")[0] == 'javascript:listBoxRemoveSelectAllDeSelectAll.selectAll()'){
      a.parentNode.removeChild(a);     
}
    }
    for(var i=0;i<a.length;i++){
alert(a.href.split("#")[0]);
        if(a.href.split("#")[0] == 'javascript:listBoxRemoveSelectAllDeSelectAll.deSelectAll()'){
      a.parentNode.removeChild(a);     
}
    }
</script>

Note:  Techniques which use JavaScript are not guaranteed to be forward compatible.

Steps:

  1. Add this script to an HTML item which is placed at the bottom of the prompt page.

  2. When the page loads this code will find the listbox by name and remove both the Select All and Deselect All links from under the Value Prompt.

Note:  The Cognos Application Firewall may need to be disabled to get this to function properly.

<script>
    var a = document.getElementsByTagName("A");
    for(var i=0;i<a.length;i++){
alert(a.href.split("#")[0]);
        if(a.href.split("#")[0] == 'javascript:listBoxRemoveSelectAllDeSelectAll.selectAll()'){
      a.parentNode.removeChild(a);     
}
    }
    for(var i=0;i<a.length;i++){
alert(a.href.split("#")[0]);
        if(a.href.split("#")[0] == 'javascript:listBoxRemoveSelectAllDeSelectAll.deSelectAll()'){
      a.parentNode.removeChild(a);     
}
    }
</script>

<script>
    var a = document.getElementsByTagName("A");
    for(var i=0;i<a.length;i++)
{
        if(a.href.split("#")[0] == 'javascript:listBoxN52.selectAll()'){
      a.parentNode.removeChild(a);     
}
    }
    for(var i=0;i<a.length;i++){
        if(a.href.split("#")[0] == 'javascript:listBoxN52.deSelectAll()'){
      a.parentNode.removeChild(a);     
}
    }
</script>
