Checkbox Item check / uncheck all
If you have an ordinary checkbox item based on a list of values, here is a function which will set all the values to checked or unchecked:
function checkboxSetAll (item,checked) {
$("#"+item+" input[type=checkbox]").attr('checked',checked);
$("#"+item).trigger("change");
}
For example:
checkboxSetAll("P1_ITEM", true); //select all
checkboxSetAll("P1_ITEM", false); //select none
It works this way because a checkbox item based on a LOV is generated as a set of checkbox input items within a fieldset.
Note: If it’s a checkbox column in a report, you can use this trick instead: Select All / Unselect All Checkbox in Interactive Report Header

Hi Jeffrey,
I was very happy when I ran into this article, since it was exactly what I was looking for.
I have added the function on the page in “Function and Global Variable Declaration”.
Then I have created 2 buttons:
– 1 to “Select All”
– and 1 for “Select None”
Both buttons call the appropriate functionusing a DA.
When I click “Select All”, the checkboxes are all selected.
Then when I click “Select None” all boxes are unchecked.
However when I click “Select All” again, nothing happens.
Do you have an idea why this is and, even better, how I should resolve this?
