html代码 
 代码如下: 
|  | 
|  | 
//iterate through each option of the listbox 
for(var count= src.options.length-1; count >= 0; count--) { 
//if the option is selected, delete the option 
if(src.options[count].selected == true) { 
try { 
src.remove(count, null); 
} catch(error) {
src.remove(count); 
} 
} 
} 
} 
 
当然,如果使用jQuery来删除,那就方便了,一句话就搞定了 
 代码如下: 
$("#sourceId").find('option:selected').remove();
