JQuery Selectors

selectors.md

the jquery code $("#searchable.dynamic-content") will match on an element that has the id searchable and the class dynamic-content. That doesn't help us much, since in the code in the issue we are trying to get at an element with the class dynamic-content that is inside an element with the id searchable. Assuming we have the following html:

<div id="searchable">
<div class="dynamic-content">...content here...</div>
</div>

the first selector won't match on anything. It would only match if we added the class dynamic-content to the outer div that has an id of searchable. However, if we add the space between #searchable and .dynamic-content, we are telling jQuery that we want an element with the class dynamic-content that is inside (aka a child of) the element with the id searchable.

In your example, $("#friendlist#friends"), you are telling jquery to look for an element with the id friendlist and the idfriends, which is not a valid selector, since an element should only have one id attribute. If you were to put a space between the two, $("#friendlist #friends"), it would match on the following:

<div id="friendlist">
  <div id="friends"> <!-- Matches this element--></div>
</div>

thank you for answer and i have a small suggestion if we can realize it
its to add Destroy method to code and when data come we will rebuild it :)

i write untested vision

`  destroy: function() {
           
           this.unbindEvents();
           this._destroy();
           this.$element.removeData();
       },

 unbindEvents: function() {
       
            var that = this;

            this.$search.off( 'change keyup', function() {
                that.search( $( this ).val() );

                that.updateStriping();
            });

            if ( searchFocusCallback ) {
                this.$search.off( 'focus', this.settings.onSearchFocus );
            }

            if ( searchBlurCallback ) {
                this.$search.off( 'blur', this.settings.onSearchBlur );
            }

            if ( this.$search.val() !== '' ) {
                this.$search.trigger( 'change' );
            }
        },
`

i don't know if it will work but i think it will be much better as you don't grantee all data come through click or keyup etc event
so some cases we cant you Jquery on function

best regards
