by Unknown in javascript , Tutorial 0
Not all browsers support all attributes on all elements. There are a number of new attributes in HTML5, so the idea of testing to see what kind of browser environment you are in becomes every increasingly important.
function elementSupportsAttribute(element, attribute) {
var test = document.createElement(element);
if (attribute in test) {
return true;
} else {
return false;
}
};Usage
if (elementSupportsAttribute("textarea", "placeholder") {
} else {
// fallback
}
