Validation - Compare Two Textfield Values (numeric) And Warn When One Is Larger?
Feb 18, 2010
I'm struggling to get what I want to work..I have two textfields (using jquery to ensure digits only, limit 3) one is total_available one is currently_available
obviously you cannot have more things available than you have in total, so i need to compare them, and warn when the second one is larger than the first. I tried to modify the jquery validation equalTo with no luck.
i actualy dont care it its not, if i can get the values from the fields, convert them to INT, then compare, and change the innerHTML of a warning DIV that is next to the fields to say "check again" then it will be sorted.
[Code]...

I'm having a problem with this script I'm working on. What I want to do is check that a user has entered only numeric characters in a text box. If not, an error message should be displayed telling the user that this field requires only numeric input.
It seems to be hitting that part of the function, but I'm not sure what I'm doing wrong that the form is still posting back. Here is the code:

I have to add some technique which will solve the following problem. A form is presented to the user in our web application. Say it has
4 text fields,
2 radio buttons (Yes / No)
1 checkbox
1 select list.
Now 2 textfields are pre-populated, one radio button (Yes) is pre-selected, checkbox is not checked, one option from select list is preselected.
Problem:
In 90% of the cases, all that the user needs to do is enter values in the 2 empty textfields and click Submit.
However, the user might change the values in the preselected controls, like check the checkbox, change radio selection from Yes to No, select a different option from the select list, change the default values from the prepopulated text fields.
Now in such a case where 'default' values are changed, I need to show a alert or a popup layer to the user when the submit button is clicked.
Showing a popup layer or an alert:
The popup layer/alert will be a confirmation popup which will say something like -
"You have changed the default values for:[all the fields which were changed by user]. This requires you to do [some task] once you submit the form.
If you do not wish to change these defaults, click Cancel.
To proceed with the changes, click OK and then Submit."
Clicking OK:
If user clicks OK, then all is well. User will click Submit to submit the form and do some task which is required when defaults are changed.
Clicking Cancel:
If user clicks Cancel then the defaults should be restored. User is now free to click Submit. Code:

It has appeared that ancient sources give a method for Numeric Date
Validation that involves numerous tests to determine month length;
versions are often posted by incomers here. That sort of code seems
unnecessarily long.
For some while, the following approach has been given here :-
function ValidDate(y, m, d) { // m = 0..11 ; y m d integers, y!=0
with (new Date(y, m, d))
return (getMonth()==m && getDate()==d) }
and it may remain the shortest code. But it does require, in every
case, the creation and disposal of a Date Object.
The following is about 50% longer in code, but about four times faster
in my system - and it seems to be right, too.
function DateOK(Y, M, D) {
return D>0 && (D<=[,31,28,31,30,31,30,31,31,30,31,30,31][M] ||
D==29 && M==2 && Y%4==0 && (Y%100>0 || Y%400==0) ) }
Note that checking for 1 <= M <= 12 is inherent, and that the Leapness
of the year is only determined if the date given is February 29th.
Also, it is easy to use only the quadrennial rule if it is certain that
dates are in 1901-2099, or only two rules for 2001-2399.

I am using Javascript to valid the textbox value..That text box should only allow numerics. So I have used IsNan function to validate the text box value. But it's not working..it is accepting chars/special chars too.
So i need to validate a textbox for negative values and chars,symbols. can any one give some idea about this..
Other than IsNan function is there anything to validate numeric value..

What's my "problem": For my website, i want a kind of postal code check. When someone fills in his postalcode and submitted this, he needs to be directed to another page, with information regarding the region that belongs to his postal code.
I will have to create a form, with only one field: postal code. The "action"of that form has to point to a javascript. That script compares the value of the filled in postalcode to some document (txt, xml ??) or database. If the two value match, the user will be directed to another url.

Does anyone have a code snippet to compare those values so I can sort
the array of alpha-numeric values that include both characters and
integers in it?
I.e., if we have values like 4236 and 123234, I want 4236 to be second
because 4 is bigger than 1 rather than using the numeric comparison.
The strings can include character values and strings. Basically, I have
the bubble sort function, the question is how to compare those types of
strings in the alpha-numeric order.
i.e.,
A83745
B34974
127734
34456
788
I looked all over the web thinking that this simple question would be
answered somewhere, but could not find the answer.

I'm currently working on a web page that's acting much like a spreadsheet. There are fields that the user must fill in and then certain columns of fields add up to a sum at the bottom. I haven't been able to get it working quite right.
Here is the essence of the code
Code:
<form name="drillreport" method="post" action="process_report.php">
<table><tr>
<td> Field 1 </td>
<td> <input type="text" name="field1" id="field1" onBlur= calcTotal() /> </td>
</tr><tr><td> Field 2 </td>
<td> <input type="text" name="field2" id="field2" onBlur= calcTotal() /> </td>
</tr><tr><td> Field 3 </td>
<td> <input type="text" name="field3" id="field3" onBlur= calcTotal() /> </td>
</tr><tr><td> Total </td>
<td> <input type="text" name="tot_col" id="tot_col" onFocus= calcTotal() /> </td>
</tr></table>
...
It is more than that of course, but you get the idea.
The function I wrote is the following:
Code:
<script type="text/javascript">
function calcTotal() {
var returned_val=0;
returned_val += parseFloat(document.drillreport.field1.value);
returned_val += parseFloat(document.drillreport.field2.value);
returned_val += parseFloat(document.drillreport.field3.value);
document.drillreport.tot_col.value = returned_val;
}
</script>
I use the onBlur for each of the "component fields" so that if the user changes one of the fields, it updates the total. However, I can't get this to return values properly when just field1 is entered ( NaN ) comes up. As soon as I enter the second column the total appears fine. Why wont this work if you just enter the first field?

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.

well i have one form, which having somewhere around 60 checkboxes and 28 textfields + 3 text areas, submit button
textfields start with name="textfield1" till "textfield28"
like
<input name="textfield1" type="text">
.........
<input name="textfield28" type="text">
now i have made one for loop to check value shouble be numeric.
my for loop
for (i=0; i<28;i++)
{
if(checknumber(document.form1.textfield[i].value)==false)
{
alert ("Please Insert Numerics only");
return false;
}}
checknumber is another function which checks for numerics.. my problem is, i m not able to increment the textfield1..28 with for loop. this for loop should work for the bunch of that 28 textfields only.. it should not take any other element in form.

I have a form that has several disabled text fields. In these text
fields, I have initial values. Next to each text field lies a "copy"
button. When clicked, the content of the disabled text field is
appended to the content of another textfield, the only one that isn't
disabled (therefore the user can copy content from the other text
fields, and also add what they want). I also have a remove button,
which clears the content of that one non-disabled text field.
Pretty easy so far.
Here's the problem. Imagine I copy the content from textfield 1 into
the blank text field, then do the same for textfield 2 and 3.
Between each "insert", I've added a comma. So the non-disabled
(active) text field would have the following content:
content1, content2, content3,
Now say that the user wants to remove content2, without removing the
rest, how could I go about doing this?

I've got a form that's nested in a larger application. I need to
program it so that the user is warned to save upon clicking on any
exit point in the application.
So, if they click on any of the nav buttons in the header/nav bar,
they need to get an alert:
"Would you like to continue without saving your changes?"
_Yes_ _No_
It would be a big pain to retrofit the application's nav
buttons/framework for just these forms, so I'm looking for a solution
that doesn't require editing the source code of the application's
existing navigation.
What are my options?

I have a php application that launches a window that is used for a database import/update (which is closed automatically when the import/update is complete). The thing is that the user could close this window and i want to pop up a warning message (but only if the user closes it) that the user can cancel (stop the closing of the window) or select OK to close the window.
I have been looking for a javascript script that accomplishes this but without luck. Does anyone know how to do this or if it's possible? (i only know a little javascript)

Ive looked and looked and can't find a solution to this problem... I want to have it so that when the users closes the window (by clicking the little [x] box at the top right hand corner), it prompts them asking if they really want to close the window. If they choose Yes then it does, if No, takes them back to where they just were. I know that this is possible with javascript, but is it possible to maybe coincide php w/ java in order to achieve this effect? If anyone can figure out a solution (possibly w/ code), ill be grateful..
secondly, is it possible to do the same w/ the user pressing the refresh button? By this i mean, if a user chooses to click the Refresh button in the toolbar of the browser, it alerts them saying somehting.
*The reason i don't ask this in the Javascript forum is because i need to work w/ php in order to do this.
