Using JavaScript to place a particular tag at a designated position

Question

Using JavaScript to place a particular tag at a designated position

I have a string that looks like this:

var txtstr='<p>Text 1</p><p>&nbsp;</p><p>Text &nbsp;2</p><p>&nbsp;</p><p>Text 3&nbsp;</p>';

I have an <img src=..../> tag and I want to insert it at a specific position within a p tag.

For example, let's say the 5th <p> tag and after the 7th character. Here, each   will count as one character only, even if there are multiple instances of  .

I tried doing something like this:

const paragraphs = str.split("</p>")
const firstParagraph = paragraphs[5]+'</p>';

but unfortunately, this method did not work as expected.

If anyone has a solution, I would greatly appreciate it. Thank you!

Thank you for checking this out.

// Here is a sample HTML string
var txtstr = "<p>Example Text 1</p><p>&nbsp;</p><p>Example Text &nbsp;2</p><p>&nbsp;</p><p>Example Text 3&nbsp;</p>";

// Specify where to insert the <img> tag (for example, after the 5th paragraph)
const insertPosition = 4;

// Define the image source
const imgSrc = "path/to/your/image.jpg";

// Generate the <img> tag
const imgTag = `<img src="${imgSrc}" />`;

// Split the text into paragraphs
const paragraphs = txtstr.split("</p>");

// Insert the <img> tag at the specified position
if (insertPosition >= 0 && insertPosition < paragraphs.length) {
  paragraphs[insertPosition] += ` ${imgTag}`;
}

// Combine the paragraphs back together to form the updated HTML string
const modifiedTxtstr = paragraphs.join("</p>");

console.log(modifiedTxtstr);

The resulting output will look like this:

<p>Example Text 1</p><p>&nbsp;</p><p>Example Text &nbsp;2</p><p>&nbsp;</p><p>Example Text 3&nbsp; <img src="path/to/your/image.jpg" /></p>
