Page Layout里的javascript (jquery)不执行

在page layout 中通过 _spBodyOnLoadFunctionNames.push("js 方法名") 的方式实现。

但切记，代码要放到 PlaceHolderMain 内部执行。

在page layout PlaceHolderMain 区域内直接写，或者在该区域引入js文件皆可。。。

e.g.

    _spBodyOnLoadFunctionNames.push("GenerateRightNavList");
    function GenerateRightNavList() {
        var currurl = location.href;
        // pages using business page layout
        if ($("#hidnIsBusinessPageLayOut").length > 0) {
            var urlparts = currurl.split("/");
            if (urlparts != null && urlparts.length > 2) {
                var itemName = urlparts[urlparts.length - 2];
                $("#nav-block>div.widget-header:eq(0)").text(itemName.replace("-", " "));
                var filterUrl = currurl.substring(0, currurl.lastIndexOf("/") + 1);
                //alert($("ul.primary-menu>li.menu-item>a[href^='"+filterUrl+"']").length);
                $("ul.sub-menu>li.menu-item>a[href^='" + filterUrl + "']").each(function () {
                    $("#menu-shortcodes").append('<li class="menu-item menu-item-type-post_type menu-item-object-page"><a href="' + $(this).attr("href") + '">' + $(this).find("span:eq(0)").text() + '</a></li>');
                });
                var pstring = "";
                var cstring = "";
                var itemobj = $("ul.primary-menu>li.menu-item>a[href^='" + filterUrl + "']:eq(0)");
                var subitemobj = $("ul.sub-menu>li.menu-item>a[href='" + currurl + "']:eq(0)");
                if (itemobj.length > 0) {
                    pstring = $.trim(itemobj.find("span:eq(0)").text());
                }
                if (subitemobj.length > 0) {
                    cstring = $.trim(subitemobj.find("span:eq(0)").text());
                }
                var breadString = pstring + (cstring != "" ? ': ' + cstring : "");
                $("#breadcrumbs").append('You are here: <a href="/home">Home</a> / ' + breadString);
            }
        }
    } 

or

<script type="text/javascript" src="/Scripts/layout.js"></script>
