问题 It seems it\'s a very well known problem but all the solutions I found on Google don\'t work on my newly downloaded IE9. Which is your favorite way in order to enable the Placeholder property on the input and textarea tags? Optional: I lost a lot of time on that and didn\'t look for the required property yet. Would you also have some advice for this? Obviously I can check the value in PHP, but to help the user this property is very convenient. 回答1: HTML5 Placeholder jQuery Plugin - by Mathias

问题 My application uses an UITextView . Now I want the UITextView to have a placeholder similar to the one you can set for an UITextField . How to do this? 回答1: I made a few minor modifications to bcd's solution to allow for initialization from a Xib file, text wrapping, and to maintain background color. Hopefully it will save others the trouble. UIPlaceHolderTextView.h: #import <Foundation/Foundation.h> IB_DESIGNABLE @interface UIPlaceHolderTextView : UITextView @property (nonatomic, retain)

How do I make a placeholder for a &#39;select&#39; box?

问题 I\'m using placeholders for text inputs which is working out just fine. But I\'d like to use a placeholder for my selectboxes as well. Of course I can just use this code: <select> <option value=\"\">Select your option</option> <option value=\"hurr\">Durr</option> </select> But the \'Select your option\' is in black instead of lightgrey. So my solution could possibly be CSS-based. jQuery is fine too. This only makes the option grey in the dropdown (so after clicking the arrow): option:first {

Is there a way to change the color of the placeholder text? 回答1: Implementation There are three different implementations: pseudo-elements, pseudo-classes, and
