下拉菜单中带有值的图标标志

Question

我有bootstrap下拉菜单，可以选择选项。我想在左侧的文本附近添加国旗。我做到了，但问题是当我在下拉列表中选择选项并提交它时，标志也会通过php / html发送。我不知道如何把它放在这里，不要用JSON.parse(temp)['0_1']提交标志，并在左侧标记。

HTML：

<li>

Answer 1

使用FontAwesome＆amp;选择下拉列表字体标志图标

         .find( '[data-bind="label"]' ).text( $target.text() )
            .end()
         .children( '.dropdown-toggle' ).dropdown( 'toggle' );
