Cross-browser currentStyle/getComputedStyle implementation
Download one of the available flavors:
- Production version
- Development version - Available via
bower install computedStyle
- CommonJS version - Available via
npm install computed-style
andcomponent install twolfson/computedStyle
- AMD version
In your web page:
<script src="dist/computedStyle.min.js"></script>
<script>
computedStyle(el, 'color'); // Returns color of the element
</script>
computedStyle
is a single purpose function
computedStyle(element, property);
/**
* Cross-browser getComputedStyle
* @param {HTMLElement} el Element to get property from
* @param {String} prop Property to look up (DOM, zIndex, and CSS, z-index, formats accepted)
* @returns Property from the browser
*
* @note These properties can vary from browser to browser.
* For example, IE6 will return #FF0000 whereas Firefox will return rgb(255, 0, 0)
* I have chosen to avoid this for this repo as it exits the single purpose
* and jQuery follows the same approach.
*/
// Grab the z-index of an element
computedStyle(el, 'z-index');
// Grab the background-color of an element
computedStyle(el, 'background-color');
