当用户点击选项中的某个选项时,我试图发出警报.
<select id="Menunavigation" class="cs-select cs-skin-slide">
<option value="Home" data-class="icon-home-cod">Start</option>
<option value="About" data-class="icon-about-cod">About</option>
<option value="Services" data-class="icon-services-cod">Start</option>
<option value="Work" data-class="icon-work-cod">Work</option>
<option value="Contact" data-class="icon-contact-cod">contact</option>
</select>
你会怎么做？
