string capacity

[Don Logan]

Hi, I have a small Javavscript function which recieves some text and a table cell ID (both PHP variables). On mouseover the text is displayed in the specified cell. This is ok if the length of the text string isn't too long but over a certain length the text isn't displayed. How do i specify the length of the string the Javascript can handle?
My function is:-

function display(text,cell){
var getText = document.getElementById(cell).innerHTML += text;
}

Thanks

Don

There seems to be a bit of confusion here when you say the function receives two parameters that are php variables.

JavaScript happens client-side and php happens server-side.

Where does the text originate from whose length you want to control.

You should be aware of a cross browser problem with the way you are doing things. It's my understanding that Firefox has a problem with innerHTML when it comes to table cells.

JavaScript can't read PHP variables. If you'd tell us a little more about what you're doing, we'll be happy to help find a solution, though.

Maybe I should have included this line of PHP which calls the function with the php variables $text and $cellID.

echo "<a href='$location' onmouseover='display(\"$text", \"$cellID\")'>$link</a>";

Here's the function again: -
function display(text,cell){
var getText = document.getElementById(cell).innerHTML += text;
}

The code works apart from the described string length problem.

Thanks

Hmm. That's odd, I don't think there's a max string length. How long are these strings?

[Don Logan]

The cut off point seems to be approx 100 characters.

Could you echo the text produced by the php code to the screen seperately so we can tell whether its php or on the html page where the text is being abreviated.

[Ryan Fait]

Which browser(s) are you testing in? As Geoff said, it could be a browser thing.

[Don Logan]

Not sure what you mean by echoing to the screen but here's what's echoed. I'm using Firefox.

echo "<td width ='50%' >\n";
echo "<a href='$location' onmouseover='display(\"$text", \"$cellID\")'>$link</a>";
echo "</td></tr>\n";
echo "<td width='50%' id = '$cellID'></td></tr>\n";

Just for debug purposes, add this line of code and then you will be able to read the value on screen. Depending where in your php you put it it might displace your layout but that's the price of debugging.

Code: Select all

print ("<b />".$text."<b />");

Lets see what you have.

[Don Logan]

I put 'print ("<b />".$text."<b />"); ' before the table, in the table and after the table, each time the full string shows. Thanks for your help so far by the way, much appreciated.

Ok, so we know that php isn't cutting your string short so it's happening client-side.

I'd like you to try a different browser and see if the same thing happens.
