TextFields Based On User Selection - Variables And Objects

Apr 10, 2011

I have 3 TextFields, called txtUSD, txtEUR, txtAUS. And a PopupList with the same values, minus the txt part, but I need to form the names of the TextFields to use based on the selection that the user made. So I've done this:

Code:
function btConvert_Click(event){
var amount = document.getElementById("txtAmount").value;
var rates = document.getElementById("lstConvertTo").value;
var from = "txt" + document.getElementById("lstFrom").options[document.getElementById('lstFrom').selectedIndex].text;
var to = "txt" + document.getElementById("lstConvertTo").options[document.getElementById("lstConvertTo").selectedIndex].text;
var curr_from = document.getElementById(from).value;
var curr_to = document.getElementById(to).value;
if(curr_from > curr_to){
amount * rates;
} else {
amount / rates;
} alert(result);
}

But every time I try it I get this error:
Code:
mobile/main.js line 215: Result of expression 'document.getElementById(from)' [null] is not an object.

JQuery :: Table Row Click That Checks Checkbox In Same Row

Dec 21, 2010

I've got it working; Clicking on the row will check the box, however now clicking the checkbox itself doesn't work I'm guessing because. It's registering as two events for that one click: One for the row that checks the mark. Two for the checkbox (which is now checked) that unchecks it. The user can click on the row but not on the checkbox itself.

Ideally since the checkbox table cell as some padding (user can click outside the <input>), I'd rather not disable the row click on that cell specifically.
$('.rule_event_table tbody tr').click(function(){
$(this).find('input:checkbox').each(function() {
if(this.checked) this.checked = false; // toggle the checkbox
else this.checked = true;
})});

Simple Math Function Between Some Textfields

Jun 9, 2009

I'm trying to write a function that does a simple math function between some textfields.

There are 4 variables : Unit price, Discount, Quantity and Total

Unit price is a fixed variable.

Discount, Quantity and Total depend on the fixed variable and also on the values of eachother. (ie : if qty=2 then total=2xUnit Price) etc...

I want to be able to show the changing values in real time.

So if I have 3 textfields and I change qty, I want it to update Total based on the discount and the qty. If I update discount, I want to update Total based on qty and discount.

I'm guessing I would have to write three functions and call each one from their respective textfields.

How to write a function, and call it so that passes the unit price to the funtion, gets the values of all of the textfields and then changes them all to their new values?

JQuery :: Function Which Prepopulates Textfields With Value Of Label

Aug 10, 2010

I have a form which looks like so:

I want to prepopulate the value of the two textfields with the field label e.g. Name, Email Address, until the fields are in focus.

I have this working for the Name field:

Obviously I can repeat this code on the email field as well, but wondered if there is a way to make it a function with the label value not hardcoded so I can use the same technique on forms with many fields.

Jquery :: First Selection Calls The Next Set Of Checkboxes?

Oct 14, 2010

So I have a three step process where the page loads and there is the first section of checkboxes... as the user makes their selections I want to display the next step which also has some checkboxes. If they select a checkbox from the next step then there's a 3rd step.

If I load all sections at once, all three groups of checkboxes works great as far as accepting selections and passing the proper information.

However if I load only one, then after selection is made, load the next one... the next one using the same code as showing all at once does NOT want to work. I can't select anything.

I'm starting with something like:

[Code].....

one is class=checklist, other is =media,... thinking the naming was conflicting and then I have them each call their own function to keep it separate.

Checkbox Validation For Multiple Checkboxes

Nov 1, 2007

I have a simple form which I'm trying to validate. I have around 8 checkboxes that the user has to agree with, and if they dont, they get the message saying "you did not accept the training princples, yada yada".

I also have a few text fields asking for their details.

Maybe I'm missing something simple here, but everytime I submit the form, it doesnt validate. Im not fantastic at coding, but I was hoping this would be quite straight forward. All I'm trying to do is get a message up if the user doesnt agree with all of the checkboxes. Code:

Checkbox Problem - Checkboxes Submitting That Are Unchecked

Jul 23, 2005

I am having a problem in my struts application with the checkboxes in
my form. I have an array of checkboxes, some of which may be already
selected when the form loads. My problem is when the user then
deselects one or more of these checkboxes and submits the form -
they're being submitted as if they were still checked, when the user
has infact deselected them.

I've heard that this is a common problem, but I don't seem to be able
to find the problem / resolution with any search criteria. If anybody
knows the fix for this it would be greatly appreciated (if there is a
solution without using Javascript I would prefer this as we're trying
to write the application so it's not too dependant on Javascript . . .
