Obtain precise Inline CSS formatting and Style designation

Question

Obtain precise Inline CSS formatting and Style designation

Is there a way to extract specific inline CSS styles from an element, capturing both the style name and its value?

Consider an element with various inline styles like this:

<div style="background-color:red; display:block; background-size:cover; background-attachment:fixed; background-repeat:repeat-y; cursor:pointer; width:100%"></div>

My goal is to retrieve the element's styles (including both the style name and value), focusing only on those related to "background" while disregarding others like "display, cursor, width," and so forth.

To achieve this using jQuery, one might execute the following code snippet:

$("div").attr("style");

This approach returns all of the element's styles, including undesired ones. Ideally, I am seeking a solution that delivers output similar to the following, filtering out non-"background" related styles:

background-color:red; background-size:cover; background-attachment:fixed; background-repeat:repeat-y;

While it is possible to access individual styles like so:

$("div").css("background");
$("div").css("background-size");

The limitation lies in obtaining just the style values without discerning between different variations such as "background-image" or "background-repeat-x/y."

Using string manipulation for this task is not recommended, and it's surprising to see other answers relying on it. The style element is the more appropriate tool for handling inline styles.

To access all inline styles, you can simply inspect element.style. This object displays each inline CSS rule separately, as shown in the image below:

The object provides a clear list of rules that can be accessed individually (for instance, element.style[0] represents background-color). It also includes a dictionary for accessing specific rules by name, allowing for easy filtering to find desired rules.

A live demo demonstrates how to extract rules containing the term background from the object (check the console). The results are organized into an array of name and value pairs for convenient access:

var el = document.getElementById("thediv");

var result = [];

for (var i = 0; i < el.style.length; i++) {
    if (el.style[i].indexOf("background") !== -1) {
        result.push({name: el.style[i], value: el.style[el.style[i]]});
    }
}

console.log(result);

<div id="thediv" style="background-color:red; display:block; background-size:cover; background-attachment:fixed; background-repeat:repeat-y; cursor:pointer; width:100%"></div>

If you want to extract background styles from div elements in jQuery, you can use the following code:

$('div').each(function() {

style_arr=$(this).attr("style").split(';');
for(i=0;i<style_arr.length;i++) {
    if(style_arr[i].indexOf('background')!=-1) {
        console.log(style_arr[i]);
    }
}

});

Here is a possible solution:

$(document).ready(function(){
    var selectedBackgroundStyles = $.grep($("div").attr("style").split(';'), function(style) {
        return style.indexOf("background") > -1;
    });
    console.log(selectedBackgroundStyles);
});

One possible way to achieve this is by following these steps:

let styleAttribute = $("div").attr("style");
let arrayOfStyles = styleAttribute.split(';');
let backgroundAttributes = '';
for (let j = 0; j < arrayOfStyles.length; ++j) {
    if (arrayOfStyles[j].includes("background")) {
        backgroundAttributes += arrayOfStyles[j] + ';';
    }
}   
console.log(backgroundAttributes);

To begin, extract the entire style attribute, then separate all CSS attributes by ";" into an array. Next, iterate through each element in the array to search for values containing "background". If found, append that value to a variable with ';' attached at the end of each one.
