I create two selectors. When I double click one option in a selector, the value selected will show in another selector. Suddenly, it didn’t work. I double click one option in the left selector that can’t get the option value. If I click one option once then double click again, it will work. I have no idea what’s happening.

    this.dClick = function(ele, ele2){
        var _nut = navigator.userAgent.toUpperCase();
        var isIE=(_nut.indexOf("MSIE") >= 0 || _nut.indexOf("WINDOW") >= 0)?true:false;
        if(isIE){
            $(ele).dblclick(function(){
                var objThis = $(this).find(':selected');
                console.log(Object.entries(objThis));
                var ok_add = true;
                
                if(ok_add){
                    var nOption = $("<option></option>").attr("value", $(objThis).val()).text($(objThis).text()).prependTo(ele2);
                    obj.dOptionClick(nOption, ele2, ele);
                    $(objThis).remove();
                    
                }   
            }); 
        }
    }

Could anyone have any suggestion? Thanks.
