Capturing values in array
I have a user filled form that contains 13 different dropdown lists from which the user can only pick values from eight of the dropdowns.
wouldn't
Code:
output[i] = document.getElementById("pdf_line_0_1_" + i).value;
make more sense?
I was not going to increment the array based on the loop values since I need to end up with 8 array values. I was going to use an if statement to determine which values were included in the array.
May be you could try the following
does your output array end up with any values in it, and what are the errors you are getting?
No values at all with that code - with my code I get
To follow up on xelawho's question, you need to be careful when and where you use document.write(). It's *possible* to use it to update the content of a page dynamically, but if you use it incorrectly you can have unexpected results. For testing purposes, I'd suggest adding a special element like:
Code:
<div id="testdiv"></div>
and then use:
Code:
document.getElementById("testdiv").innerHTML += output[i];
to see your results.

I am not sure what you mean for me to do
I guess it's something else then, because this simple test:
Code:
<html>
<head>
</head>
<body>
<input type='text' value="1" id="pdf_line_0_1_1"/>
<input type='text' value="2" id="pdf_line_0_1_2"/>
<input type='text' value="3" id="pdf_line_0_1_3"/>
<script type="text/javascript">
output = [];
for (var i = 1; i < 4; i++ ) {
output[i] = document.getElementById("pdf_line_0_1_" + i).value;
document.write("<br>"+output[i])
}
</script>
</body>
</html>
works fine.
Change output[i] = "document.getElementById('pdf_line_0_1_" + i + "').value";
I think I may have suggested something similar back in post#2, J2NYC...

looks like rtrethewey was on the money - document.write messes you up. try this:
Code:
function show_alert(){
document.getElementById("block_Info Block").innerHTML=""
output = [];
for (var i = 1; i <= 13; i++ ) {
output[i] = document.getElementById("pdf_line_0_1_" + i).value;
document.getElementById("block_Info Block").innerHTML+=output[i]+"<br>"
}
}
OK - so how would I use this function - sorry to be such a NOOB but I have not done alot in javascript - I usually have done everything in PHP.
