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)))

}

使用XPath和document.evaluate()，并确保使用text()而不是。为contains()参数，否则你将匹配整个HTML，或最外层的div元素。

var headings = document.evaluate("//h1[contains(text(), 'Hello')]", document, null, XPathResult.ANY_TYPE, null );

或者忽略前导和尾随空格

var headings = document.evaluate("//h1[contains(normalize-space(text()), 'Hello')]", document, null, XPathResult.ANY_TYPE, null );

或匹配所有标签类型(div, h1, p等)

var headings = document.evaluate("//*[contains(text(), 'Hello')]", document, null, XPathResult.ANY_TYPE, null );

然后迭代

let thisHeading;
while(thisHeading = headings.iterateNext()){
    // thisHeading contains matched node
}

我一直在寻找一种使用Regex来做类似事情的方法，并决定构建我自己的东西，如果其他人正在寻找类似的解决方案，我想分享它。

function getElementsByTextContent(tag, regex) {
  const results = Array.from(document.querySelectorAll(tag))
        .reduce((acc, el) => {
          if (el.textContent && el.textContent.match(regex) !== null) {
            acc.push(el);
          }
          return acc;
        }, []);
  return results;
}

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
