Hello again..... :-/
I have a strange problem and can't find anything on it no the net or in my books.
I am printing a table using this function...
But when it prints out to either IE or NS I get a ++ before the table. If create the table in the loop I get a ++ before each table. The ++ doesn't appear in the generated source, but only in the output on the screen. What am I doing wrong?
function buildTable() {
var value = document.form1.rowNum.value;
document.write("<table width='95%' border='1' cellspacing='0' cellpadding='0'>"+
"<tr bgcolor='#FFFFCC'><td colspan='14' class='tableHeader'>Detail of Inquiry</td>"+
"</tr>+<tr>+<td colspan='5' bgcolor='#FFFFCC' class='tableHeader'>General Ledger Code</td>"+
"<td width='7%' class='tableHeader' rowspan='2' align='center' bgcolor='#FFFFCC'>Report<br>Date</td></tr></table>")
for (var i = 1; i <= value; i++) {
document.write("<br>Hello")
}
document.close()
}

i tried making a page from your code but it doesnt display anything. im not enough expert to know why. i tried putting it in the body tag but that didnt work either

<html><head></head>
<script language="javascript">
document.write("<table width='95%' border='1' cellspacing='0' cellpadding='0'>"+
"<tr bgcolor='#FFFFCC'><td colspan='14' class='tableHeader'>Detail of Inquiry</td>"+
"</tr><tr><td colspan='5' bgcolor='#FFFFCC' class='tableHeader'>General Ledger Code</td>"+
"<td width='7%' class='tableHeader' rowspan='2' align='center' bgcolor='#FFFFCC'>Report<br>Date</td></tr></table>")
for (var i = 1; i <= value; i++) {
document.write("<br>Hello")
}
document.close()
}
</script>
</html>

i see i missed part of the code i try again

arg it still doesnt display anything. i will learn this language yet!

<html><head></head>
<script language="javascript">
function buildTable() {
var value = document.form1.rowNum.value;
document.write("<table width='95%' border='1' cellspacing='0' cellpadding='0'>"+
"<tr bgcolor='#FFFFCC'><td colspan='14' class='tableHeader'>Detail of Inquiry</td>"+
"</tr><tr><td colspan='5' bgcolor='#FFFFCC' class='tableHeader'>General Ledger Code</td>"+
"<td width='7%' class='tableHeader' rowspan='2' align='center' bgcolor='#FFFFCC'>Report<br>Date</td></tr></table>")
for (var i = 1; i <= value; i++) {
document.write("<br>Hello")
}
document.close()
}
window.on load = buildTable;
</script>
</html>

i had to change onload to on load so ubb would accept it. anyway i cant see anything wrong with your code i just wanted to see the effect

Correct... that doesn't display anything
there is more to it i didn't think i needed to put it.
If you are trying to use the code i posted put it in between the <head> javaScript in here </head>
in the body of the html i have something like this
<body>
<form name="form1">
<input type="text" name="nameOfTextField">
<input type="button" action="javascript:functionName">
</form>
</body>
just that code it self won't produce anything
and for the ubb code when i'm at work tomorrow i'll cut n paste it again correctly sorry....
and that html code up there isn't 100% right i just whipped it up to give a general idea.

Ok,
the reason why ++ would appear on your page is because it got included in the literal HTML that you were generating:
- Strings are delimited by ""
- + can be used to concatenate Strings
- some of your +'s were included in the Strings and are being treated as literals as opposed to contentation operators.
I tried to explain that in my post above, but didn't do such a good job.

Randall, Rich,
sorry for the confusion, I was originally trying to highlight the part of Rich's code that had the issue, with the UBB bold tag, but it wasn't working out for me.
So after 3 attempts the above post was the outcome (it made sense in my mind

james, no need for apologies you solved his problem

im not real fond of UBB myself. i find it very iritating to have to modify the code for events when html is supposed to be disabled. it has even been mentioned in the moderators only forum that this is a pain.

in fact i think something must be done about it. at least some message in this forum saying you dont have to change all your <'s and >'s but only have to change the event code. i am gonna go start a thread about it.

it's done, hopefully soon there will be bold red text explaing about the shortcoming of UBB and what to do. i hate to imagine someone tediously changing all their <'s and >'s because thats what UBB recommends
