Modify <style> following jQuery scripts

Question

Modify <style> following jQuery scripts

Upon loading a site, I utilized a jQuery script to capture the background color of the header. This action occurs when the page is loaded with the cue

$(document).ready(function(global)

. My goal is to then insert this captured value into the background style property of a table.

The current setting for the table's properties is established using <style> / </style> tags. Unfortunately, this setup causes a conflict because the script needs to obtain the desired values before the styles are applied. As a result, the color variable cannot be directly integrated into the <style> tags since the <script> runs after the <style> tags have been processed.

The dilemma lies in how to orchestrate the execution of <style> tags post the completion of a <script>, allowing me to input the stored variable into the styling elements.

I realize this arrangement may seem counterintuitive, but due to the stringent parameters of the application I'm developing, I must adhere to this sequence. Back-end encoding of the colors is not feasible as they are housed in transient cache files, leaving me constrained by the circumstances I've outlined above.

Answer 1

Answer №1

Instead of using jQuery to modify the stylesheet directly, it is used to manipulate the DOM just like a stylesheet would.

The changes in styling are made through the .style property.

Here is an example of changing the background using .backgroundColor:

var headerColour = document.getElementById('header').style.backgroundColor;
var element = document.getElementById('element');
element.style.backgroundColor = headerColour;

#element {
  height: 100px;
  width: 100px;
  background: red;
}

<div id="header" style="background-color: green"></div>
<div id="element"></div>

It's important to note that even though the CSS specifies the square to be red, the JavaScript overrides it and makes the square green. Styling applied through JavaScript will automatically take precedence over CSS (as demonstrated above).

I hope this explanation is helpful! :)
