Javascript plugin appending duplicate data in WordPress

4 Views

I’m using a currency conversion plugin called curry.js that’s being called on a custom WordPress page with bootstrap tabs and advanced custom fields.

As WP loops through each tab it’s appending to the list of currencies so that when you open the dropdown in the third tab you see the list of currencies repeated three times.

Here’s the portion of the code curry.js is running each time: 

var generateDDM = function( rates ){

        output = '';

        // Change all target elements to drop downs
        dropDownMenu.each(function(){

            for (var i in rates ) {

                rate = rates[i];

                output += '<option value="'+ i +'" data-rate="'+ rate +'">' + i + '</option>';

            }

            $( output ).appendTo( this );

        });

    };

I’ve tried creating a counter variable outside that block of code so that after it runs once and creates the list of currencies, it stores that list in a global output variable which is no longer appended to, but to no avail.

If further clarification is needed, I’m happy to provide–any help would be fantastic I’ve spend many hours trying to figure this out and I know it should be a very simple solution.

Thanks!

  1. Solved this with a simple if statement checking the length of the output variable after each WP loop:

    dropDownMenu.each(function(){
  if(output.length < 251) {
    for ( var i in rates ) {
      rate = rates[i];          
        output += '<option value="'+ i +'" data-rate="'+ rate +'">' + i + '</option>';
    }
    $( output ).appendTo( this );
  }
  else {
    $( output ).appendTo( this );
  }
});
