Hi,

Is it possible to make a script to change HTML on the page?

Also, is there a script to remove images from a page?

Reason I ask is that we don't have access to change the HTML, but I would like to alter the table at the top, but don't know how too. Is this possibe?

thanks

Peter :)

Can you be a little more specific?

I need something to change tables, maybe something to change the width of one of them? I don't have access to the HTML, but can add HTML, Javascript to the page.

As for the script to remove images on a page, I figured that out :D

Thanks

Peter :)

Something like this?


<html>
<head>
<title> Título </title>
</head>
<script language="JavaScript">

function changeWidth(table,width)
{
table.style.width=width;
}


</script>
<body>
<table id="tbl" border=1 style="width:300px;" cellspacing=0 cellpadding=0>
<tr>
<td>td</td>
<td>td</td>
<td>td</td>
</tr>
<tr>
<td>td</td>
<td>td</td>
<td>td</td>
</tr>
</table>

<input type="button" value="Change to 300px" onClick="changeWidth(tbl,300);">
<input type="button" value="Change to 500px" onClick="changeWidth(tbl,500);">
</body>
</html>


Didn't try it in NS...:rolleyes:

Sorry, better try and explain better.......

I have a remotely hosted message board, and its has a table at the top. I can't add, change or do anything to the table except for change colours from the preferences in my admin section.

There is a section to modify headers and footers. This is where I can add additional things to the board, etc style, html, javascript, images....

I wanted to alter the top table, but can't the way you posted. There are basically 2 tables, 1 at the top and then 1 below that which contains the listed forums. I can't adjust the size of the top one, only the second one by adding <table width="xx%"><tr><td> into the header and adding the closing tags in the footer. Only way I can see of changing the top one is with Javascript.

Does the table (the one you want to change) have the width defined at all? If it is not defined you can put it in another table or a div and shrink it that way. If it is defined as a percentage you can put it in another table or a div and stretch/shrink it that way. Not sure about any way of doing it via javascript.

Hmm, ok I think I understood this time..:confused:

Maybe you can get the first table through a function like this?



function getTable()
{
var i;
for(i=0;i<document.childNodes.length;i++)
if(document.childNodes[i].tagName=="TABLE")
return document.childNodes[i];
return -1;
}



After that you should be able to make the desired changes...



var headerTbl=getTable();
if(headerTbl!=-1)
{
headerTbl.style.whatever="whatever";
}



Hope I got it this time...:p

It's likely if you have a remotely hosted message board, that they use the table in question for advertising purposes or whatever - and in that case it's probably against their TOS to modify/change it - have you contacted them?

If it IS against their TOS, then they'll likely refuse to host a message board for your website if you attempt to modify it...
