sharepoint 2010 显示和隐藏Ribbon区域条

在sharepoint 2010的页面中，我们在页面的最上方，有一条深灰色的Ribbon工具栏，如下图，这里可以通过下面的脚本，做一些脚本，来控制它的隐藏和显示。

最后把这些脚本，放在v4.master母板页的<div id="s4-workspace"></div>这个标签里面。

<div style="background-color: gray;text-align: right">

    <input type="button"  id="hideRibbon"  value="显示" onclick="HideRibbonFunc()"/>

    <wssuc:welcome id="IdWelcome"  runat="server"  enableviewstate="false">

            </wssuc:welcome>

    <wssuc:muiselector id="IdMuiSelector" runat="server" />

    <style>

        .ms-welcomeMenu a:link

        {

            /* [ReplaceColor(themeColor:"Light1",themeTint:"0.9")] */

            color: white;

        }

        .ms-welcomeMenu.ms-SpLinkButtonActivea:link

        {

            /* [ReplaceColor(themeColor:"Light1",themeTint:"0.9")] */

            color: white;

        }

    </style>

</div>

<script>

    function HideRibbonFunc() {

        var ribbonrowObj = document.getElementById("s4-ribbonrow");

        if (ribbonrowObj.style.display =="none") {

            document.getElementById("hideRibbon").value ="隐藏";

            ribbonrowObj.style.display = "";

        }

        else {

            document.getElementById("hideRibbon").value ="显示";

            ribbonrowObj.style.display = "none";

        }

    }

</script>
