Currently, I have a Javascript function that returns a specific value. When this value is returned, I want to dynamically change the colors of different table headers based on their id.
Is there a way to change the color of a table header in javascript without simply applying CSS styling? Should I consider conditionally calling specific CSS styles depending on certain criteria?
Thank you, Van
To update the appearance of the table header in question, modify the class name using Javascript.
By doing this, you can maintain your styles in CSS and simply swap out the class name on the header to change its style.
Consider leveraging the capabilities of the jQuery Javascript framework for a more efficient approach, utilizing its addClass() method.
Replace the current element class with a different class specified in your CSS file.
document.getElementById('headerID').style.color = '#{color}';

It is possible to manipulate CSS using JavaScript effortlessly. For instance, utilizing jQuery allows you to alter the background color of an element based on a certain condition 'x':
if(x) $('#test').css('background-color', 'green');
However, a more sophisticated approach would involve changing the class of the relevant element and establishing different styles for each class in your CSS.
To modify the appearance of an element, you can change its class based on the return value of a function.
document.getElementById('FOO').className += 'new-class'
Alternatively, you have the option to adjust the style of an element using JavaScript like this:
document.getElementById('FOO').style = { color: '#FFF', backgroundColor: '#000' };
