get img src and set as variable

Getting img src and Setting it as a Variable

Have you ever needed to get the source of an image and store it in a variable for later use? Maybe you want to display the same image in multiple places on your webpage without having to manually copy and paste the src every time. Here's how you can do it:

Method 1: Using JavaScript

// Get the image element by its ID
var img = document.getElementById("myImg");

// Get the src attribute of the image
var src = img.src;

// Set the src attribute of a new image element
var newImg = document.createElement("img");
newImg.src = src;

In this method, we first use JavaScript to get the image element by its ID. We then use the .src property to get the src attribute of the image element and store it in a variable called src. Finally, we create a new image element and set its src attribute to the src variable that we just created.

Method 2: Using jQuery

// Get the src attribute of the image
var src = $("#myImg").attr("src");

// Set the src attribute of a new image element
var newImg = $("").attr("src", src);

If you're using jQuery, you can accomplish the same thing with less code. In this method, we first use jQuery to get the src attribute of the image element and store it in a variable called src. We then use jQuery to create a new image element and set its src attribute to the src variable that we just created.

Method 3: Using PHP

<?php
// Get the src attribute of the image
$src = "img/myImg.jpg";
$src = htmlspecialchars($src); // Sanitize the input

// Set the src attribute of a new image element
echo "<img src='$src'>";
?>

If you're using PHP, you can use the htmlspecialchars() function to sanitize the input and prevent XSS attacks. In this method, we first store the src attribute of the image in a variable called $src. We then use PHP to echo out a new image element with the src attribute set to the $src variable that we just created.

Conclusion

There are multiple ways to get the src attribute of an image and set it as a variable. Whether you're using JavaScript, jQuery, or PHP, these methods allow you to easily reuse images on your webpage without having to manually copy and paste the src every time.
