该解决方案实现如下功能:

Uses the ES6 spread operator to convert the NodeList of all divs to an array. Provides output if the div contains the query string, not just if it exactly equals the query string (which happens for some of the other answers). e.g. It should provide output not just for 'SomeText' but also for 'SomeText, text continues'. Outputs the entire div contents, not just the query string. e.g. For 'SomeText, text continues' it should output that whole string, not just 'SomeText'. Allows for multiple divs to contain the string, not just a single div.

[…document.querySelectorAll('div')] //获取数组中所有div .map(div => div. innerhtml) //获取它们的内容 .filter(txt => txt.includes('SomeText')) //只保留包含查询的内容 .forEach(txt => console.log(txt));//输出这些的全部内容 <div> . SomeText, text continue .</div> . SomeText, text continue <div>不在这个div中 这里是更多的SomeText.</div> .

因为你已经在javascript中要求它，所以你可以有这样的东西

function contains(selector, text) {
  var elements = document.querySelectorAll(selector);
  return Array.prototype.filter.call(elements, function(element){
    return RegExp(text).test(element.textContent);
  });
}

然后像这样叫它

contains('div', 'sometext'); // find "div" that contain "sometext"
contains('div', /^sometext/); // find "div" that start with "sometext"
contains('div', /sometext$/i); // find "div" that end with "sometext", case-insensitive

如果你不想使用jquery或类似的东西，那么你可以试试这个:

function findByText(rootElement, text){
    var filter = {
        acceptNode: function(node){
            // look for nodes that are text_nodes and include the following string.
            if(node.nodeType === document.TEXT_NODE && node.nodeValue.includes(text)){
                 return NodeFilter.FILTER_ACCEPT;
            }
            return NodeFilter.FILTER_REJECT;
        }
    }
    var nodes = [];
    var walker = document.createTreeWalker(rootElement, NodeFilter.SHOW_TEXT, filter, false);
    while(walker.nextNode()){
       //give me the element containing the node
       nodes.push(walker.currentNode.parentNode);
    }
    return nodes;
}

//call it like
var nodes = findByText(document.body,'SomeText');
//then do what you will with nodes[];
for(var i = 0; i < nodes.length; i++){ 
    //do something with nodes[i]
} 

在数组中拥有包含文本的节点后，就可以对它们进行操作。比如提醒每个人或打印到控制台。需要注意的是，这可能并不一定会抓取div本身，这将抓取拥有您正在寻找的文本的textnode的父节点。

这里已经有很多很棒的解决方案了。但是，为了提供一个更精简的解决方案，并且更符合querySelector行为和语法的思想，我选择了一个用几个原型函数扩展Object的解决方案。这两个函数都使用正则表达式来匹配文本，但是，字符串可以作为松散搜索参数提供。

简单地实现以下函数:

// find all elements with inner text matching a given regular expression
// args: 
//      selector: string query selector to use for identifying elements on which we 
//                should check innerText
//      regex: A regular expression for matching innerText; if a string is provided,
//             a case-insensitive search is performed for any element containing the string.
Object.prototype.queryInnerTextAll = function(selector, regex) {
    if (typeof(regex) === 'string') regex = new RegExp(regex, 'i'); 
    const elements = [...this.querySelectorAll(selector)];
    const rtn = elements.filter((e)=>{
        return e.innerText.match(regex);
    });
    
    return rtn.length === 0 ? null : rtn
}

// find the first element with inner text matching a given regular expression
// args: 
//      selector: string query selector to use for identifying elements on which we 
//                should check innerText
//      regex: A regular expression for matching innerText; if a string is provided,
//             a case-insensitive search is performed for any element containing the string.
Object.prototype.queryInnerText = function(selector, text){
    return this.queryInnerTextAll(selector, text)[0];
}

实现了这些函数后，现在可以进行如下调用:

document.queryInnerTextAll('div.link', 'go'); This would find all divs containing the link class with the word go in the innerText (eg. Go Left or GO down or go right or It's Good) document.queryInnerText('div.link', 'go'); This would work exactly as the example above except it would return only the first matching element. document.queryInnerTextAll('a', /^Next$/); Find all links with the exact text Next (case-sensitive). This will exclude links that contain the word Next along with other text. document.queryInnerText('a', /next/i); Find the first link that contains the word next, regardless of case (eg. Next Page or Go to next) e = document.querySelector('#page'); e.queryInnerText('button', /Continue/); This performs a search within a container element for a button containing the text, Continue (case-sensitive). (eg. Continue or Continue to Next but not continue)

我也有类似的问题。

函数返回包含arg文本的所有元素。

这对我来说很管用:

function getElementsByText(document, str, tag = '*') {
return [...document.querySelectorAll(tag)]
    .filter(
        el => (el.text && el.text.includes(str))
            || (el.children.length === 0 && el.outerText && el.outerText.includes(str)))

}

由于数据属性中的文本长度没有限制，所以请使用数据属性!然后你可以使用常规的css选择器来选择你的元素(s)像OP想要的。

for (document.querySelectorAll("*")的常量元素){ element.dataset.myInnerText = element.innerText; ｝ 文档。querySelector(“* [data-my-inner-text = '不同的文本。']”).style.color =“蓝色”; <div> . SomeText, text continue .</div> . SomeText, text continue 不同文本< div >。< / div >

理想情况下，您可以在文档加载时完成数据属性设置部分，并缩小querySelectorAll选择器的范围以提高性能。
