Semantic Ui Menu not working

问题

I am trying to work with semantic ui menu.

But I cannot get it to work, ie when I click the items in the menu, the active state isn't changing. I didn't find any examples in the web either.

HTML :

<div class="ui grid">
        <div class="one wide row">
            <div class="ui green menu">
                <a class="active item">
                    <i class="home icon"></i> Home
                </a>
                <a class="item">
                    <i class="mail icon"></i> Messages
                </a>
                <div class="right menu">
                    <div class="item">
                        <div class="ui transparent icon input">
                            <input type="text" placeholder="Search...">
                            <i class="search link icon"></i>
                        </div>
                    </div>
                </div>
            </div>
        </div>
    </div>

JS:

$(document).ready(function() {
    $('.ui .green .menu').menu();
});

I have taken the code snippet from the semantic-ui website.

Some help is appreciated.

回答1:

here's a handler similar to the one on their demo site

DEMO

screenshot:

  $('.ui.green.menu')
    .on('click', '.item', function() {
      if(!$(this).hasClass('dropdown')) {
        $(this)
          .addClass('active')
          .siblings('.item')
            .removeClass('active');
      }
    });

Try:

$(document).ready(function() {
    $('.ui.green.menu').menu();
});

Classes ui, green and menu are applied on the same element. They're not descendants of one another.

To make your menu LIVE with jQuery use this.

From the Semantic UI example

$('.ui.menu .ui.dropdown').dropdown({
  on: 'hover'
});
$('.ui.menu a.item').on('click', function() {   
  $(this)
    .addClass('active')
    .siblings()
    .removeClass('active'); 
})
