按 Enter 正在创建标签，但将文本保留在 Select2 中

Question

Select2 Version: 4.0.5

Problem: In a multitag (with tags: true or with pre-filled tags) everytime when i hit enter to select the tag, it creates the tag but keeps the text right on side of the new tag, it just disappear if I press another key after. (Happens only with Enter key)

Example:

As you can see, when I type a tag and press Enter, it creates the tag (the expected behavior) but, it keeps the original text in the right side of the new tag...

Is it a normal behavior? Or what should I do?

My Select2 Code:

 var editorTagElement = document.createElement("select");
 editorTagElement.className('myEditor');
 editorTagElement.setAttribute("multiple", "multiple");
 editorTagElement.style.overflow = 'auto';
 editorTagElement.style.fontSize = '13px';

 this.OptionsSelect2 = {};
 this.OptionsSelect2.placeholder = "";
 this.OptionsSelect2.language = ReturnCustomLanguage();
 this.OptionsSelect2.formatNoMatches = function () {
        return '';
 }; 
 this.OptionsSelect2.allowClear = true;
 this.OptionsSelect2.minimumInputLength = 2;
 this.OptionsSelect2.tags = true;
 this.OptionsSelect2.tokenSeparators = [' '];          
 this.OptionsSelect2.createTag = function (params) {              
       var term = $.trim(params.term);
       if (term.length < 2) {
              return null;
       }
       term = term.replace(/ /g, "");         
       return {
            id: term,
            text: term,
            newTag: true
       }
 };
 this.OptionsSelect2.closeOnSelect = false;

 $('.myEditor').select2(this.OptionsSelect2);

After this, I append the editor to body or to another place in my html...

Option closeOnSelect is keeping the value, while it's not an expected behaviour. If you will change closeOnSelect to true (default value, just remove this.OptionsSelect2.closeOnSelect = false; in your code) it will work as you expect.

To keep popup open after adding a value, you should write a handler similar to suggested in the github issue
