I'm using cheerio.js to parse some HTML documents, but I'm facing certain problems.
The thing is the HTML file I am using contains the following code:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>
</title>
</head>
<body>
<p>Text 1</p>
<p>Text 2</p>
</body>
</html>
Now, I also have a javascript array of Items like this:
var items = ["<h2>orange</h2>", "<h2>mango</h2>"];
What I want to do is simply replace each P tags with the respective item in the items array, i.e something to this:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>
</title>
</head>
<body>
<h2>orange</h2>
<h2>mango</h2>
</body>
</html>
What I tried so far:
var selections = $("p");
for ( let index = 0; index < selections.length; index++ ) {
selections[index].replaceWith(items[index])
}
But it says that function replaceWith() is not valid
Solution:
using the each method, one can easily process particular elements
solving the above problem:
var items = ["<h2>orange</h2>", "<h2>mango</h2>"];
$("p").each((index, element) => $(element).replaceWith(items[index]))
Basically the each method will invoke a callback function where element is the selector of that particular element, and index is the position of the item in that selection.
