Not showing placeholder for input type="date" field
If you use mvp's method but add the onblur event to change it back to a text field so the placeholder text appears again when the input field looses focus. It just makes the hack a little bit nicer.
<input placeholder="Date" class="textbox-n" type="text" onfocus="(this.type='date')" onblur="(this.type='text')" id="date" />
Hope this helps.
I ended up using the following.
Regarding Firefox comment(s): Generally, Firefox will not show any text placeholder for inputs type date. But as this is a Cordova/PhoneGap question this should be of no concern (Unless you want to develop against FirefoxOS).
input[type="date"]:not(.has-value):before{
color: lightgray;
content: attr(placeholder);
}
<input type="date" placeholder="MY PLACEHOLDER" onchange="this.className=(this.value!=''?'has-value':'')">
It may not be appropriate... but it helped me.
<input placeholder="Date" class="textbox-n" type="text" onfocus="(this.type='date')" id="date">
