Simple.js testing for input placeholder

[smlombardi]

You can test if a placeholder is currently being displayed by checking the input.__placeholder property,

How, exactly? Can you please provide an example?

[kbjr]

var elem = document.getElementsByTagName('input')[0];

if (elem.__placeholder == null) {
    // no placeholder is defined for this element (the polyfill is not initialized for this elem)
} else if (elem.__placeholder) {
    // placeholder text is being displayed
} else {
    // placeholder text is not being displayed
}
