how to retain Select2 results after select?

问题

For example, when using select2 muti-value, user entered 'new', and it showed

• New Mexcio
• New Hampshire
• New Jersey
• New York

After selecting 'New Mexcio', and the user would like to select again from the rest of the 3 remaining. In order to to do that, the user has to enter 'new' again.

Is there a way to retain the results instead of clear out the 'query?

Thanks

Sounds like you want to persist a query from one search to the next. You might want to check out the nextSearchTerm property.

To display the current value in the next search,

function displayCurrentValue(selectedObject, currentSearchTerm) {
  return currentSearchTerm;
}

$("#e1").select2({
  nextSearchTerm: displayCurrentValue
});
