Problem With Multiple Text Boxes Using Formated Numbers

Aug 13, 2007

I'm primarily a database programmer (Mysql and PHP) but I have some Javascript programming and I have been programming in other languages for over 25 years.

On to my problem:

I'm trying the create a function in Javascript which will take a variable from three different text boxes and show the net result in a fourth text box that is ReadOnly. This is all on the same page. All three text boxes have other Javascript scripts formatting the value in the text boxes.

Real example (simplified)....

Finding The Position Of The Cursor In A Text Box & Rich Formated <textarea>

Feb 16, 2006

Question 1
----------------
I am writing an advanced BBCode system for my forums and I would like
to be able to find where the cursor was positioned last in the text so
I could insert the BBCode there.

Question 2
----------------
Again I am writing an advanced BBCode system for my forums and I would
like to make is so that when someone puts in a [b] tag it goes bold, so
kind of a WYSIWYG editor and also for other things like [img] tags and
[url] tags. So could someone tell me how to do that. I would preferably
like it to still use the textarea tag, or at least a form component so
my existing code works.

Compare Values In Multiple Text Boxes

Apr 5, 2006

I've a page where I'm calling record from Database. Each record has an
ID and a text box displayed on the page. When the user fills in the
values of a text box, depending on the values of the text box i've to
do some further work. For eg. I've to add two records if the textbox
value of 2 records is same.

I'll try to create an example here
<-----this is from the DB-------> <-----this is form field--->
ID Task Hrs text box
1 adsfsd 1 a <---- user fills this
2 asdf 1.5 b <---- user fills this
3 eyst 2 a <---- user fills this
4 dghjfghj 2 c <---- user fills this
5 xdfb 1 b <---- user fills this
6 tyety 1.5 c <---- user fills this
________
| Submit |
--------------

So the user has to add hrs of those boxes for which have same values
entered by user. such as adding hrs of record 1 and 3 since both have
"a" entered by the user, adding record 2 and 5, as both have "b"
entered by the user and so on and so forth.

Calculate Subtotal - Tax And Total Using Multiple Text Boxes

Apr 15, 2009

I am trying to simulate a simple checkout page where a user inputs the quantity of merchandise that they want in multiple text boxes. When they click "calculate" it calculates the subtotal, tax, and total. As it stands my calculate function works if I do quantity * price for each text box and then add together. I would have to do this 9 times! :eek: I would like to use an array but I am not exactly sure how to use it to do calculations. I know I need a loop (which I have written) and an array (which is written also).

Multiple Tracking Numbers On The Same Page?

Jul 9, 2010

I put this code together so it can assign appropriate links to tracking numbers provided by shipping carriers. It works, but on the page where I need to use it sometimes I have more than one tracking number listed and div ids are the same, so on click on any tracking number it always takes the value of the first div listed on the page. Is it possible to change something in the code so it can work for multiple tracking numbers on the same page?

Multiple Array And Random Numbers ?

Nov 10, 2010

I have a quick question with multiple array and random numbers. If i generate my random numbers in one array, how would i take a selection of those numbers and put them in another array?

Ex: array 1: 25, 34, 38, 40, 22, 49

Want to move numbers between 30 and 50 to another array.

array 2: 34, 38, 40, 49

Is it as simple as for loops and if statements setting the conditions? do i use a sorting method? (selection? bubble?)

Multiple Dropdown Select Boxes?

Nov 19, 2010

I'm populating a couple of dropdown boxes from an xml file, but can't get them working independently. As you can seehtmwhen you select an item from the first select box (a polyline), itdisplays the corresponding item from the other box (a polygon), too.I found this answer on the google maps forum:"Don't know of an example, but building two select boxes isn'tdifficult: pass into your createMarker() function the relevant flag,and add the data to one of two variables (instead of everything beingadded to select_html as now).You shouldn't need two handleSelected() functions -- both select listscan use the same function because each select box passes itself("this") into the function."which is what I thought I did (making sel_html and select_html) butmaybe the two variables being discussed here are different ones?cross-posted on the google maps forum here and here but not answered.

JQuery :: Multiple Select Boxes Changing A Div Value?

Oct 29, 2011

I'm not entirely familiar with jQuery coding, but I've given it my best shot to get this script working properly, and I can't seem to manage it. Here is my scenario: I'm creating a website for a friend who sells custom jewelery cuts. There are 4 different parameters you have to choose about your cut, and we would like to change the image displayed to match the parameters you select so you have a picture of what your going to purchase. The idea is like this:

I have managed to get it to update the image for a single select box, but then If I select another one it completely overrides the first one, and displays the second box. Here is what I have so far (and no it doesn't work :P):

This ensures that when only one select box is chosen, the form validates, however, it also validates if no boxes are selected. What's the most efficient way of doing this?
