I am trying to verify the contents of a form before sending it. Basically, I'm trying to work with the numbers in the form and ensure they are within the correct range. The problem is that the JavaScript I have which is trying to verify it thinks that the item being passed to it is NaN (I have been parsing it).
A little work revealed that the variable (size) is referring to an HTMLInputEleMent, which I guess is, indeed, NaN (although I am not quite sure what it actually is). I think that the problem is that the onSubmit is not passing what I want it to be passing, even though I named the field size and I passed onSubmit size too.
I tried putting it in quotation marks, but that just turns it into a string...
I am wondering if perhaps you are unable to pass a variable from WITHIN the form to it's onSubmit field? Is that so? If so, how should I do this?
Here is the form:
<form onsubmit=return goodForm(size, day, month, year) action=http://localhost:8080/pomper_servlet/CostCalc method=GET>
The day of the month must be entered as a number (ex: 1,22)
<input type=text name=day><br>
The month of the year must be entered as a number (ex: Jan.=1, etc.)
<input type=text name=month><br>
The year must be entered as a 4 digit number (ex: 2008, 2017)
<input type=text name=year><br>
Please Choose a tour-length, in accordance with the chart below:
<input type=TEXT name=length><br>
How many people will be in your group? (No More than 10 allowed!)
<input type=text name=size><br>
Please select a tour:<br>
<input type=RADIO name=tour value=Gardiner Lake>
Gardiner Lake<br>
<input type=RADIO name=tour value=Hellroaring Plateau>
Hellroaring Plateau<br>
<input type=RADIO name=tour value=The Beaten Path>
The Beaten Path<br>
<input type=SUBMIT value=Submit>
</form>
And here is the function, from functions.js:
function goodForm(gSize, day, month, year) {
use strict;
window.alert(goodFrame(): +gSize);
var groupSize1 = parseInt( gSize.replace(/^|$/g, ), 10);
window.alert(goodFrame(): +groupSize1);
var sizeInt = parseInt(groupSize1);
if(groupSize(sizeInt) && goodDate(day, month, year)){
window.alert(true);
return true;
}
else{
window.alert(false)
return false;
}
There are references to other functions in there, but they aren't relevant to this, I think. The alerts were/are for debugging purposes...
Thanks in advance!
