本文翻译自：[jQuery: find element by text][jQuery_ find element by text]

*Can anyone tell me if it's possible to find an element based on its content rather than by an **id** or **class** ?* **谁能告诉我是否有可能根据其内容而不是ID或类来查找元素？**

*I am attempting to find elements that don't have distinct classes or id's.* **我正在尝试查找没有不同类或ID的元素。** *(Then I then need to find that element's parent.)* **（然后，我需要找到该元素的父对象。）**

*In jQuery documentation it says:* **在jQuery文档中说：**

> *The matching text can appear directly within the selected element, in any of that element's descendants, or a combination* **匹配的文本可以直接出现在所选元素中，该元素的任何后代中或组合中**

*Therefore it is not enough that you use `:contains()` selector , you also need to check if the text you search for is the **direct content** of the element you are targeting for, something like that:* **因此，仅使用`:contains()` *选择器*还不够，还需要检查搜索的文本是否是您要定位的元素的直接内容 ，例如：**

function findElementByText(text) {
        var jSpot = $("b:contains(" + text + ")")
                    .filter(function() { return $(this).children().length === 0;})
                    .parent();  // because you asked the parent of that element
    
        return jSpot;
    }

*Rocket's answer doesn't work.* **火箭的答案不起作用。**

<div>hhhhhh
    <div>This is a test</div>
    <div>Another Div</div>
    </div>

*I simply modified his [DEMO here][] and you can see the root DOM is selected.* **我只是[在这里][DEMO here]修改了他的[DEMO][DEMO here] ，您可以看到已选择根DOM。**

$('div:contains("test"):last').css('background-color', 'red');

*add " **:last** " selector in the code to fix this.* **在代码中添加“ ：last ”选择器以解决此问题。**

*Best way in my opinion.* **我认为最好的方法。**

$.fn.findByContentText = function (text) {
        return $(this).contents().filter(function () {
            return $(this).text().trim() == text.trim();
        });
    };

*Fellas, I know this is old but hey I've this solution which I think works better than all.* **Fellas，我知道这很老了，但是我有这个解决方案，我认为它比所有方法都有效。** *First and foremost overcomes the Case Sensitivity that the jquery :contains() is shipped with:* **首要的是克服了jquery：contains（）附带的区分大小写的问题：**

var text = "text";
    
    var search = $( "ul li label" ).filter( function ()
    {
        return $( this ).text().toLowerCase().indexOf( text.toLowerCase() ) >= 0;
    }).first(); // Returns the first element that matches the text. You can return the last one with .last()

*Hope someone in the near future finds it helpful.* **希望不久的将来有人对您有所帮助。**

*The following jQuery selects div nodes that contain text but have no children, which are the leaf nodes of the DOM tree.* **以下jQuery选择包含文本但没有子级的div节点，它们是DOM树的叶节点。**

$('div:contains("test"):not(:has(*))').css('background-color', 'red');

<div>div1 <div>This is a test, nested in div1</div> <div>Nested in div1<div> </div> <div>div2 test <div>This is another test, nested in div2</div> <div>Nested in div2</div> </div> <div> div3 </div> <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/1.12.4/jquery.min.js"></script>
