Initialize value from variable

@wwwapprenticeMay 11.2011 — #Normally you set the default value like this;

[code=html]Year: <input type="text" name="year" id="year" value="2011" />[/code]

But when you want some variable to be at that place, you are already busy with javascript. Javascript can of course edit the value attribute. So you simply set the value in the code itself.

Here's a full example, although I didn't specify a value hardcoded, javascript will fill it in for me. I 've wrapped it in an onload so that it executes when everything is ready.

[code=html]<html>
 <head>
 <title>This year example</title>
 <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
 <script type="text/javascript">
 window.onload = function(){
 document.getElementById("year").value = 2011;
 };
 </script>
 </head>
 <body>
 Year: <input type="text" name="year" id="year" />
 </body>
 </html>[/code]

And then of course you can easily change the value into something variable, like the actual year. ?

Let me know if this helped!
