Running code when the page is loaded

2023-03-26 17:43 问答作者：

I have this link that fills a开发者_开发问答n input when clicked.

<a href="#" onclick="javascript:document.getElementById('input').value='<?php echo("$ms"); ?>'">

I was wondering how I would get it to do this automatically onload.

I usually put it in onload, don't know if there is a best practise:

<body onload="myFunc()">

Assuming $ms has been made safe for XSS:

<input value="<?php echo $ms; ?>">

You can use the onload property of an element :

<body onload="javascript:document.getElementById('input').value='<?php echo("$ms"); ?>'">

Add the onLoad event to the <body> element of your document:

<body onload="javascript:document.getElementById('input').value='<?php echo("$ms"); ?>'">

Furthermore, it looks like you are using PHP, if you just want to use $ms to set the value of #input you could also use something like:

<?php
echo '<input type="text" id="input" value="'.$ms.'"/>
?>
