jQuery if div contains this text, replace that part of the text

Question

Like the title says, I want to replace a specific part of the text in a div.

The structure looks like this:

<div class="text_div">
    This div contains some text.
</div>

And I want to replace only "contains" with "hello everyone", for example. I can't find a solution for this.

Lambda

What about if the text was 'This div contains some text which contains some letters' and I wish to change the 1st contains, not the 2nd one. Or just select any word and it will be changed by predefined one. – Midwinter

Answer 1

You can use the text method and pass a function that returns the modified text, using the native String.prototype.replace method to perform the replacement:

​$(".text_div").text(function () {
    return $(this).text().replace("contains", "hello everyone"); 
});​​​​​

Here's a working example.

You can use regex /iwantreplacethis/g for all ocurences – Rori

Thank you so much for this :) one simple question: why doesn't this work without the return – Sprage

@AaronMatthews This answer was a very long time ago but I believe it would be because the jQuery text method, when passed a function, sets the text of the selection to the return value of that function. Without the return the text would be replaced with nothing. – Gyrostatic

This solve a complex issue for me, thank you – Breadthways

Answer 2

If it's possible, you could wrap the word(s) you want to replace in a span tag, like so:

<div class="text_div">
    This div <span>contains</span> some text.
</div>

You can then easily change its contents with jQuery:

$('.text_div > span').text('hello everyone');

If you can't wrap it in a span tag, you could use regular expressions.

Very simple just use this code, it will preserve the HTML, while removing unwrapped text only:

jQuery(function($){

    // Replace 'td' with your html tag
    $("td").html(function() { 

    // Replace 'ok' with string you want to change, you can delete 'hello everyone' to remove the text
          return $(this).html().replace("ok", "hello everyone");  

    });
});

Answer 5

You can use the contains selector to search for elements containing a specific text

var elem = $('div.text_div:contains("This div contains some text")')​;
elem.text(elem.text().replace("contains", "Hello everyone"));

this will replace more than one word if my string contains more than one target words, what will be then? – Spectacle
