[javascript] Javascript .querySelector find <div> by innerTEXT

How can I find DIV with certain text? For example:

<div>
SomeText, text continues.
</div>

Trying to use something like this:

var text = document.querySelector('div[SomeText*]').innerTEXT;
alert(text);

But ofcourse it will not work. How can I do it?

Google has this as a top result for For those who need to find a node with certain text. By way of update, a nodelist is now iterable in modern browsers without having to convert it to an array.

The solution can use forEach like so.

var elList = document.querySelectorAll(".some .selector");
elList.forEach(function(el) {
    if (el.innerHTML.indexOf("needle") !== -1) {
        // Do what you like with el
        // The needle is case sensitive
    }
});

This worked for me to do a find/replace text inside a nodelist when a normal selector could not choose just one node so I had to filter each node one by one to check it for the needle.

Use XPath and document.evaluate(), and make sure to use text() and not . for the contains() argument, or else you will have the entire HTML, or outermost div element matched.

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

or ignore leading and trailing whitespace

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

or match all tag types (div, h1, p, etc.)

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

Then iterate

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

Since there are no limits to the length of text in a data attribute, use data attributes! And then you can use regular css selectors to select your element(s) like the OP wants.

for (const element of document.querySelectorAll("*")) {_x000D_
  element.dataset.myInnerText = element.innerText;_x000D_
}_x000D_
_x000D_
document.querySelector("*[data-my-inner-text='Different text.']").style.color="blue";

<div>SomeText, text continues.</div>_x000D_
<div>Different text.</div>

Ideally you do the data attribute setting part on document load and narrow down the querySelectorAll selector a bit for performance.

You could use this pretty simple solution:

Array.from(document.querySelectorAll('div'))
  .find(el => el.textContent === 'SomeText, text continues.');

1. The Array.from will convert the NodeList to an array (there are multiple methods to do this like the spread operator or slice)

2. The result now being an array allows for using the Array.find method, you can then put in any predicate. You could also check the textContent with a regex or whatever you like.

Note that Array.from and Array.find are ES2015 features. Te be compatible with older browsers like IE10 without a transpiler:

Array.prototype.slice.call(document.querySelectorAll('div'))
  .filter(function (el) {
    return el.textContent === 'SomeText, text continues.'
  })[0];

If you don't want to use jquery or something like that then you can try this:

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]
} 

Once you have the nodes in an array that contain the text you can do something with them. Like alert each one or print to console. One caveat is that this may not necessarily grab divs per se, this will grab the parent of the textnode that has the text you are looking for.

You best see if you have a parent element of the div you are querying. If so get the parent element and perform an element.querySelectorAll("div"). Once you get the nodeList apply a filter on it over the innerText property. Assume that a parent element of the div that we are querying has an id of container. You can normally access container directly from the id but let's do it the proper way.

var conty = document.getElementById("container"),
     divs = conty.querySelectorAll("div"),
    myDiv = [...divs].filter(e => e.innerText == "SomeText");

So that's it.

This solution does the following:

• 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')]      // get all the divs in an array_x000D_
  .map(div => div.innerHTML)               // get their contents_x000D_
  .filter(txt => txt.includes('SomeText')) // keep only those containing the query_x000D_
  .forEach(txt => console.log(txt));       // output the entire contents of those

<div>SomeText, text continues.</div>_x000D_
<div>Not in this div.</div>_x000D_
<div>Here is more SomeText.</div>

I had similar problem.

Function that return all element which include text from arg.

This works for me:

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)))

}

There are lots of great solutions here already. However, to provide a more streamlined solution and one more in keeping with the idea of a querySelector behavior and syntax, I opted for a solution that extends Object with a couple prototype functions. Both of these functions use regular expressions for matching text, however, a string can be provided as a loose search parameter.

Simply implement the following functions:

// 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];
}

With these functions implemented, you can now make calls as follows:

• 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)

Since you have asked it in javascript so you can have something like this

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

And then call it like this

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

Here's the XPath approach but with a minimum of XPath jargon.

Regular selection based on element attribute values (for comparison):

// for matching <element class="foo bar baz">...</element> by 'bar'
var things = document.querySelectorAll('[class*="bar"]');
for (var i = 0; i < things.length; i++) {
    things[i].style.outline = '1px solid red';
}

XPath selection based on text within element.

// for matching <element>foo bar baz</element> by 'bar'
var things = document.evaluate('//*[contains(text(),"bar")]',document,null,XPathResult.ORDERED_NODE_SNAPSHOT_TYPE,null);
for (var i = 0; i < things.snapshotLength; i++) {
    things.snapshotItem(i).style.outline = '1px solid red';
}

And here's with case-insensitivity since text is more volatile:

// for matching <element>foo bar baz</element> by 'bar' case-insensitively
var things = document.evaluate('//*[contains(translate(text(),"ABCDEFGHIJKLMNOPQRSTUVWXYZ","abcdefghijklmnopqrstuvwxyz"),"bar")]',document,null,XPathResult.ORDERED_NODE_SNAPSHOT_TYPE,null);
for (var i = 0; i < things.snapshotLength; i++) {
    things.snapshotItem(i).style.outline = '1px solid red';
}
