Is it possible to parameterize the adding of classes in jQuery?

Is it feasible to parameterize the jQuery addClass() function to set specific CSS properties when called? For example, applying a color property to a CSS class when addClass() is invoked?

I am relatively new to JavaScript and CSS, so any guidance would be greatly appreciated. I'm currently working on enhancing the MediaWiki VisualEditor, where the addClass() method is utilized to instantly display changes made in the editor. However, I have not come across an example that demonstrates parameterization.

If this customization is not achievable, I would appreciate any alternative methods or suggestions on how to achieve the desired outcome.

Edit:

Currently, when I add a language annotation to the text using the following code:

this.$element
    .addClass( 've-ce-languageAnnotation' )
    .addClass( 've-ce-bidi-isolate' )
    .prop( {
        lang: this.model.getAttribute( 'lang' ),
        dir: this.model.getAttribute( 'dir' ),
        title: this.constructor.static.getDescription( this.model )
    } );

The CSS style for ve-ce-languageAnnotation class is as follows:

.ve-ce-languageAnnotation {
border-bottom: 1px dashed #ccc;
background-color: #ebf3f5;
}

And for ve-ce-bidi-isolate:

.ve-ce-bidi-isolate {
unicode-bidi: isolate;
unicode-bidi: -moz-isolate;
unicode-bidi: -webkit-isolate;
}

My attempt at creating a textColor annotation:

this.$element
    .addClass( 've-ce-textColorAnnotation' )
    .prop( {
        color: this.model.getAttribute( 'style' ),
        title: this.constructor.static.getDescription( this.model )
    } )
    ;

The style for ve-ce-textColorAnnotation class is:

.ve-ce-textColorAnnotation {
    color: red;
}

However, this always results in red text. Entering an invalid color value does not produce any changes.

Edit2: One approach could be to create a separate class for each color option and add the corresponding class based on the parameter value, like this:

var color = this.model.getAttribute('style');
if (color == 'blue') {
    this.$element.addClass( 'blueText' )
} else if (...

But this does not seem like an optimal solution.

Edit 3: An answer on this question on Stack Overflow suggests that directly applying attributes using

this.$element.css('attr', 'value')
might be a more suitable approach than parameterizing CSS classes for achieving the desired functionality.

Answer №1

It seems like your goal is to change the color of an element without adding a class. While classes in HTML are usually used for styling or navigating the DOM, in your case, a simple color change does not require the use of classes, especially if the colors are subject to change.

To achieve this, you can utilize jQuery's .css() method. You can provide multiple CSS properties as arguments like this:

element.css({
  'color': 'black',
  'height': '100px'
});

Alternatively, if you only need to modify a single property, you can use:

element.css('color', 'black');

Without relying on jQuery, you can also achieve the same result using plain JavaScript:

element.style.color = 'black';

Answer №2

Looking for a straightforward solution? Imagine having a dropdown menu where you select colors. Each color option has a corresponding value attribute, such as blueText for blue, redText for red, and so on.

By retrieving the selected value using JavaScript (find out how here), you can then apply CSS classes like redText, blueText, etc. When the user clicks on an option, you simply execute this small snippet of code:

this.$element.addClass( 'text from value attribute' )

Feel free to remove any existing classes before adding the new one.
