先看下頁面展示圖

html 程式碼

<div class="select_div">
		<div class="left_div">
			<div class="title">河段</div>
			<select id="leftSelect" multiple="multiple"
				class="multiple_select">
			</select>
		</div>
		<div class="left_div">
			<div style="margin: 20px 0 0 50px;"></div>
			<div style="margin-top: 150px;">
				<div style="margin: 20px 0 0 50px;">
					<button class="select_btn" onclick="moveToOther('right')">&gt;</button>
				</div>
				<div style="margin: 20px 0 0 50px;">
					<button class="select_btn" onclick="moveToOther('left')">&lt;</button>
				</div>

			</div>
		</div>

		<div class="left_div">
			<div class="title">被選中河段</div>
			<select id="rightSelect" multiple="multiple"
				class="multiple_select">

			</select>

		</div>
	</div>
 

左右兩個select的id分別為leftSelect、rightSelect,

js實現方法

function moveToOther(direction) {
		var fromobj = null;
		var toobj = null;
		if (direction == 'right') {
			fromobj = $('#leftSelect');
			toobj = $('#rightSelect');
		} else {
			fromobj = $('#rightSelect');
			toobj = $('#leftSelect');
		}
		fromobj.find("option:selected").each(function(){
			$(this).appendTo(toobj);
		});
	}
