如何解决yii2中动态表单上的select 2 widget错误

This is what the error looks like:

The error only exists when I use select 2 on dynamic form widget by wbrangca. And also same problem occurs for depdropdown.

Console error:

jquery.js:1468 Uncaught Error: Syntax error, unrecognized expression: #salesqty-{$i}-catagory_id

And the javascript looks like:

var $hasSelect2 = $(widgetOptionsRoot.widgetItem).find('[data-krajee-select2]');
if ($hasSelect2.length > 0) {
    $hasSelect2.each(function() {
        var id = $(this).attr('id');
        var configSelect2 = eval($(this).attr('data-krajee-select2'));

        if ($(this).data('select2')) {
            $(this).select2('destroy');
        }

        var configDepdrop = $(this).data('depdrop');
        if (configDepdrop) {
            configDepdrop = $.extend(true, {}, configDepdrop);
            $(this).removeData().off();
            $(this).unbind();
            _restoreKrajeeDepdrop($(this));
        }
        var s2LoadingFunc = typeof initSelect2Loading != 'undefined' ? initSelect2Loading : initS2Loading;
        var s2OpenFunc = typeof initSelect2DropStyle != 'undefined' ? initSelect2Loading : initS2Loading;
        $.when($('#' + id).select2(configSelect2)).done(s2LoadingFunc(id, '.select2-container--krajee'));

        var kvClose = 'kv_close_' + id.replace(/\-/g, '_');

        $('#' + id).on('select2:opening', function(ev) {
            s2OpenFunc(id, kvClose, ev);
        });

        $('#' + id).on('select2:unselect', function() {
            window[kvClose] = true;
        });

       if (configDepdrop) {
            var loadingText = (configDepdrop.loadingText) ? configDepdrop.loadingText : 'Loading ...';
            initDepdropS2(id, loadingText);
        }
    });
} 

If I don't use the select 2 widget there will be no error on console.

if you still need... Check for the use of single

'

instead of

"
