Appending new selections after pre-populating with Ajax.

[in...@monstermove.uk]

Hi, guys. I hope someone can help me. I have a multiple select field on a profile page which accepts postcodes. My visitors can choose postcodes from an Ajax populated list which I implode and save to the database as a string. When the user returns to their profile page, I pre-populate the field with the saved items like so...

// Split the postcodes
var postcodes = data.postcodeReach.split(',');

for(i=0; i < postcodes.length; i++){
$('.select2-selection__rendered').append('<option class="select2-selection__choice" title="'+postcodes[i]+'"><span class="select2-selection__choice__remove" role="presentation">×</span>'+postcodes[i]+'</option>');
}

My problem is, that if a user tries to add further items to the pre-populated list, it removes all of the existing items instead of appending them.

I have two Ajax instances working on this field. One works on a database table with all of the postcodes in the system and the other pulls data from a row in the
user profile table. I'm wondering if there is a conflict.

I hope someone can help.

Kind regards,
