$('.menu-item-text').each(function() {

  this.textContent.trim() === 'Benefits HIDDEN' && $(this).closest('li').hide();

});

Answer 2

由于许多元素都包含该文本（不仅仅是span它所在的元素，还有 the liis spanin、itsul等，甚至#zz13_idPDPQuickLaunch元素本身），因此您必须更加具体地选择您的选择器。

理想情况下，向要隐藏的最里面的元素添加一个类或其他内容。但你也可以从结构上做到这一点。例如，如果您想隐藏lis：

$(document).ready(function() {
    $("#zz13_idPDPQuickLaunch li ul li.static:contains('Benefits HIDDEN')").hide ();
});

实例：

$(document).ready(function() {

    $("#zz13_idPDPQuickLaunch li ul li.static:contains('Benefits HIDDEN')").hide ();

});

<div class=" noindex ms-core-listMenu-verticalBox" id="zz13_idPDPQuickLaunch">

    <ul class="root ms-core-listMenu-root static" id="zz14_RootAspMenu">

        <li class="static">

            <a class="static menu-item ms-core-listMenu-item ms-displayInline ms-navedit-linkNode" href="/sites/pwa/">

                <span class="additional-background ms-navedit-flyoutArrow">

<span class="menu-item-text">Defra Benefits Dev</span></span>

            </a>

            <ul class="static">

                <li class="static"><a class="static menu-item ms-core-listMenu-item ms-displayInline ms-navedit-linkNode" href="/sites/pwa/"><span class="additional-background ms-navedit-flyoutArrow"><span class="menu-item-text">Project Information</span></span></a></li>

                <li class="static selected"><a class="static selected menu-item ms-core-listMenu-item ms-displayInline ms-core-listMenu-selected ms-navedit-linkNode" href="/sites/pwa/"><span class="additional-background ms-navedit-flyoutArrow"><span class="menu-item-text">Benefits</span><span class="ms-hidden">Currently selected</span></span></a></li>

                <li class="static"><a class="static menu-item ms-core-listMenu-item ms-displayInline ms-navedit-linkNode" href="/sites/pwa/"><span class="additional-background ms-navedit-flyoutArrow"><span class="menu-item-text">Benefits HIDDEN</span></span></a></li>

                <li class="static"><a class="static menu-item ms-core-listMenu-item ms-displayInline ms-navedit-linkNode" href="/sites/pwa/"><span class="additional-background ms-navedit-flyoutArrow"><span class="menu-item-text">Benefits HIDDEN</span></span></a></li>

            </ul>

        </li>

        <li class="static"><a class="static menu-item ms-core-listMenu-item ms-displayInline ms-navedit-linkNode" href="javascript:PDPInfrastructure.NavigateWSSPage(0,true)"><span class="additional-background ms-navedit-flyoutArrow"><span class="menu-item-text">Project Site</span></span></a></li>

    </ul>

</div>

这就是说，您只想隐藏包含该文本的元素，前提是它们是 #zz13_idPDPQuickLaunch` 元素内的a 内的类li的元素。staticulli




Answer 3

您需要循环每个“li”项目并首先检查其中的文本。尝试这个：

$(function(){

            var menu_items = $("#zz14_RootAspMenu").find("li");

          menu_items.each(function(idx,el){

            var current_text = $(el).find('.menu-item-text').text();

            if(current_text == "Benefits HIDDEN"){

              $(this).hide();

            }

          })

        });
