Adjusting the height of one element based on the height of another element in multiple cases using jQuery

I am currently using jQuery to retrieve the height of one div and apply that value as a CSS property to another.

Let's take a look at a sample layout:

<div class="row">
  <div class="column image">
    <img src="image.jpg" />
  </div>
  <div class="column content">
    <p>Content</p>
  </div>
</div>
<div class="row">
  <div class="column content">
    <p>Content</p>
  </div>
  <div class="column image">
    <img src="image.jpg" />
  </div>
</div>

Here is the relevant jQuery code:

function displayHeight( element, height ) {
$( "div.image" ).css("height", height);
}

displayHeight( "div", $( ".content" ).height() );

This function extracts the height from ".content" and applies it to ".image". While this works for single instances, my goal is to create a more versatile solution that can handle multiple instances without duplicating functions.

Answer №1

If you want to dynamically adjust the height of the .image elements based on the height of the preceding .content element, you can achieve this by looping through them in jQuery.

function updateImageHeight() {
    // loop through all image elements
    $( "div.image" ).each(function(){
        // get the height of the previous .content element
        var contentHeight = $(this).prev('.content').height() || $(this).next('.content').height();

        // set the height of the image element
        $(this).css("height", contentHeight);
    });
}

// call the function to update the image heights
updateImageHeight();

Keep in mind that this implementation assumes that the .image elements are positioned after the corresponding .content elements.

<div class="row">
  <div class="column content">
    <p>Content</p>
  </div>
  <div class="column image">
    <img src="image.jpg" />
  </div>
</div>
<div class="row">
  <div class="column content">
    <p>Content</p>
  </div>
  <div class="column image">
    <img src="image.jpg" />
  </div>
</div>

UPDATE:

To ensure the script works regardless of the order of the .content and .image elements, modify the line from:

var contentHeight = $(this).prev('.content').height();

to:

var contentHeight = $(this).prev('.content').height() || $(this).next('.content').height();
