如何在下拉值选择中显示内容？

问题描述：

为了提高知名度

And for visibility

<script>
$(function(){   
        
    $("#Alert").click(function(){
        $('#AlertsTable').show();
    });  
    
});

现在我已经修改了这个

Now I have Modified into this

<select id="myDropdown" width="200" size="2"> 
                    	<option value="Alert" id="Alert" selected="selected">Alert</option>
                		<option value="IR">IR</option>
                		<option value="Site">Site</option>
                		<option value="Devices">Devices</option>                    	
                	</select>

我尝试过：

起初我把这样的值设为

What I have tried:

At first I had put values like this

<div id="myDropdown" class="dropdown-content">
    <a value="Alert" type="button" class="btn btn-lg btn-default" href="#">Alert</a>
    <a value="IR" type="button" class="btn btn-lg btn-default" href="#">Incident Report</a>
    <a value="Site" type="button" class="btn btn-lg btn-default" href="#">Site</a>
    <a value="Devices" type="button" class="btn btn-lg btn-default" href="#">Devices</a>
  </div>

答

（function（）{

(function(){

（ #Alert）。点击（function（）{

("#Alert").click(function(){

（'＃AlertsTable'）。show（）;
}）;

} ）;

('#AlertsTable').show(); }); });
