	<td id="imgmenu1" height="28" class="menu_title" style="cursor:hand"><img id="i1" src="images/NodeClose.jpg" onclick="chkClick(this);" /><span>社会科</span></td>

	
	<script type="text/javascript">
	<!--
	function chkClick(img)
	{
	img.src = img.src.toLowerCase().indexOf("NodeClose.jpg")!=-1?"images/NodeOpen.jpg":"images/NodeClose.jpg";
	-->
	</script>

	

	<script type="text/javascript">
	var SwitchPicArr = new Array("../Images/black_minus.jpg","../Images/black_plus.jpg")
	
	function setDetailMsgRow(rowID, btn) {
	 var row = document.getElementById(rowID);
	 if (row != null) {
	 if (row.style.display == (document.all ? "block" : "table-row")) {
	 row.style.display = "none";

	 if (btn != null) {
	 btn.style.backgroundImage = "url(" + SwitchPicArr[1] + ")";
	 }
	 }
	 else {
	 row.style.display = (document.all ? "block" : "table-row");
	 if (btn != null) {
	 btn.style.backgroundImage = "url(" + SwitchPicArr[0] + ")";
	 }
	 }
	 }

	// if (btn != null) {
	//// if (btn.value != "Hide Detail") {
	//// btn.value = "Hide Detail";
	//// }
	//// else {
	//// btn.value = "Display Detail";
	//// }

	// }

	 }

	</script>

	
	.cshtml 部分：
	 @if (item.MessageDetail == "")
	 { @Html.Raw("")}
	 else {
	 <input type=button value="" onclick="setDetailMsgRow('@sTmpRowID',this)" style="background:url(../Images/black_plus.jpg);width:40px;height:40px"/>
	 }
