ViewsPreventing Apex Button Double click
Hi I have a button that inserts empty records into an interactive grid. I want to prevent the user from being able to double click that button because it populates duplicate rows. I have a server side argument that says if there are rows the button does not appear however they are still able to double click the Populate_tables button before it vanishes. If there are any other solutions to this please sound off. I've tried everything from javascript to server-side but they are still able to double click no matter what. Here are the before and after pictures of the table.

$('#btnPopulateTbl').dblclick(function(e){
e.preventDefault();
});
The above code prevents the double click for a button. This is in jQuery.

Oracle Apex does not offer this functionality as a setting or etc. However you can use
$('#button').click(function(event) {
if(!event.detail || event.detail == 1){
// This will be executed once even user clicks multiple times
}
});
Note that your selector must be the id or the class you provide to this button. By default 'add row' button's classes are:
class="a-Button a-Toolbar-item js-actionButton"

Another solution would be to have apex handle this. Suppose this is on page 1.
- Create a page item P1_POPULATE_ROWS_CLICKED with a default value of 'N'
- In the page process that populates the table, add the following line before the actual load:
:P1_POPULATE_ROWS_CLICKED := 'Y';
- Add a condition to the page process that populates the table of "Item not equal to value", P1_POPULATE_ROWS_CLICKED , Y
Yet another solution is to only execute the insert statement if no rows exist with that condition yet. I can't show you how to do it because you didn't show how the table is populated but happy to do so if you edit your question. This last option is propably the most suitable.
