JavaScript Events - OnDblClick
(Page 5 of 5 )
Sometimes you want those slackers viewing your page to get a little exercise. Why have them click once when you can force them to do it twice? Well I am going to show you how to do it:
<html>
<body>
First Name: <input type="text" id="field1" value="James ">
<br />
Last Name: <input type="text" id="field2" value="Payne">
<br /><br />
Full Name: <input type="text" id="field3">
<br /><br />
Click the button below to combine the First and Last Names<br />
<button ondblclick="document.getElementById('field3').value=
document.getElementById('field1').value + document.getElementById('field2').value">Click Me!</button>
</body>
</html>
Look familiar? That’s because it is. All I did was change the word onclick to ondblclick. Done. Though technically I don’t think those are words. But whatever.
Supporting HTML Tags: <a>, <address>, <area>, <b>, <bdo>, <big>, <blockquote>, <body>, <button>, <caption>, <cite>, <code>, <dd>, <dfn>, <div>, <dl>, <dt>, <em>, <fieldset>, <form>, <h1> to <h6>, <hr>, <i>, <img>, <input>, <kbd>, <label>, <legend>, <li>, <map>, <object>, <ol>, <p>, <pre>, <samp>, <select>, <small>, <span>, <strong>, <sub>, <sup>, <table>, <tbody>, <td>, <textarea>, <tfoot>, <th>, <thead>, <tr>, <tt>, <ul>, <var>
Supporting Javascript Objects: document, link
We could also mix the single and double click events if we wanted to. And let’s face it, you know you want to.
Behold the complex code!
<html>
<body>
First: <input type="text" id="First" value="James">
<br />
Last: <input type="text" id="Last" value="Bond ">
<br /><br />
Full: <input type="text" id="full"><br /><br />
<button ondblclick="document.getElementById('full').value=
document.getElementById('last').value + document.getElementById('first').value">Double Click</button>
<br /><br />
First Name: <input type="text" id="field4" value="James ">
<br />
Last Name: <input type="text" id="field5" value="Payne">
<br /><br />
Full Name: <input type="text" id="field6">
<br /><br />
<button onclick="document.getElementById('field6').value=
document.getElementById('field4').value + document.getElementById('field5').value">Single Click</button>
</body>
</html>
The above code combines our previous two examples, allowing users to single click and double click.
Well that’s all for this episode. In the next tutorial we will cover some more JavaScript events. I hope this tutorial was helpful.
