Question

HTML onload - using variables as parameters

Answer 1

+2 A:

You would have to use HTML entities to make it work:

<body onLoad="init('A sentence with &quot;quoted text&quot; as parameter')">

the much cleaner way, though, would be to assign the value in a separate <SCRIPT> part in the document's head.

...
<script>
body.onload = function() { init('A sentence with "quoted text" as parameter'); }
</script>
<body>
...

the onload event has the general downside that it is fired only when the document and all its assets (images, style sheets...) have been loaded. This is where the onDOMLoad event comes in: It fires when the core HTML structure is ready, and all elements are rendered. It is not uniformly supported across browsers, though, so all frameworks have their own implementation of it.

The jQuery version is called .ready().

Thanks much. Am a beginner in javascript so missed such alternative styles.

@JP19 I had an error in the second block. If you use the code, make sure you copy over the change (The additional `function() { }`). Sorry.

Answer 2

+1 A:

Rather than inlining the onLoad method, why not set it programatically. You can then use the power of closures to get the data into the function.

<script type="text/javascript">
var data = "some data";
document.body.onload = function()
{
    alert(data);
}
</script>

Answer 3

A:

By the way, I was making a silly mistake.

<script language="JavaScript"> 
var dada='A sentence with \"quoted text\" as parameter'; </script> 
<body onLoad="init(dada, '</a>')">

This works too. I was using $dada instead of dada in the onload call.

Answer 4

A:

not the nicest way

onload='init("A sentence with \"quoted text\" as parameter")'
