Substring And Slice - Get The Value Of An Input Box After A Delete Key Has Been Pressed At A Certain Position

Oct 28, 2010

I'm trying to get the value of an input box after a delete key has been pressed at a certain position. For example: If I have: afghanistan and my caret is at position 4 and I push delete I will be left with: afghnistan I'm able to determine the caret position and detect the delete key and then I am trying to use slice to return the new value of the string like: Code: value.slice(caretPosition,caretPosition+1) This returns the value of what was sliced out of the string - how can I modify the parameters of slice to return everything BUT the removed part?

Recording The Id Of A Input-text If A Particular Key Is Pressed

Aug 2, 2010

I need a javascript that could record the ID/name of a textbox when the user hit delete or backspace to be used on the next page after submission in a PHP script.

There are 96 text boxes, they are all randomly placed on the screen with a question that came from a randomized array's keys (the script later checks the values of the textboxes with the values from the array's keys that correlate to the textboxes by the name/id of the textbox, which is assigned by a for loop that issues the next($array) to assign everything everywhere.

At the same time, it needs to count how many times the backspace/delete were pushed and have that recorded and sent as well.

After 45 minutes of research I've been able to solve the "count the backspace/delete key" problem:

<script type="text/javascript">
var count = 0;
document.onkeypress=function(e){
var e=window.event || e

[Code]....

But onto the name/id issue: I'm not sure how to go about retrieving the names/id of the textboxes. I would assume a onkeypress event for every textbox, but hope that there could be something I could just add to this code.

Array.slice() Not Creating An Independent Copy.

Mar 11, 2007

Alright, am I missing something?

I create a 2D array like so:

var blah = [];
blah[0] = ['one', 'two', 'three'];
blah[1] = ['four', 'five', 'six'];

Then I *attempt* to create an independent copy based on all of the pages I have read that
said it was as so:

var copy_of_blah = blah.slice(); // does not create independent copy
var copy_of_blah = blah.slice(0); // nor does this

I tested it by immediately changing either:

blah[0][0] = '' // "one" is now ''

*or*

copy_of_blah[0][0] = '' // "one", is again, ''

And of course both reflect changes upon the other.

Is it possible to create an independent copy of an array without having to write a
function that dumps the contents into a new array?

Smart Substring

Sep 9, 2007

If I have the following variable which contains the drop down menu for list of card numebrs:

var abc='<option value="1234567890123456">1234567890123456</option><option value="0987654321987654">0987654321987654</option><option value="0147852369014785">0147852369014785</option>'

How can I pass this variable to a function and mask only the dispalyed card number? i.e. to have the following result:

<option value="1234567890123456">1234XXXXXXXX3456</option><option value="0987654321987654">0987XXXXXXXX7654</option><option value="0147852369014785">0147XXXXXXXX4785</option>

Note: the number of options in the drop down menu may varry, in this example its only 3 options, it might be more or less, this is why I called it "Smart Substring".

Replacing A Varying Substring With Itself Plus

Jul 23, 2005

I'd like to globally replace a substring specified by a regular
expression with itself along with some additional characters.
example:

var oldString = 'asdf BRACKETTHISasdfsdf sd asdBRACKETTHISasdf asd'

var newString =
oldString.replace(/sw*BRACKETTHISw*/g, '<' + ?some expression that
accesses current match? + '>' )

And newString winds up as:
'asdf <BRACKETTHISasdfsdf> sd <asdBRACKETTHISasdf>
asd'

Is there a way to do this, or do I have to use other methods?

Substring Syntax In Javascript

Jul 23, 2005

Trying to debug someone else's javascript code. There is a line that

looks like this:

req = req.substring(req.length-2, req.length);

From what I can gather in their comments, they want to capture the last two characters of the string "req".

I'm guessing that the above line won't do that, and they want to change it to

req = req.substring(req.length-1, 2);

In other words, the parameters are starting position, and length. Is that correct?

Substring A Value For Display And Concatenate For Validation?

Feb 28, 2006

I have a validation script for upc codes which is currently working for
values that are entered into one text box. I've been asked to break up
the text box into 3 separate fields to accept the 1st digit, middle 10
digits, then last check digit. What I'm doing is substringing the
initial values then concatenating them. What I'm not sure of is, how to
handle the validation. I was previously firing an onBlur after the text
box but now that I have three, and I need the values to concatenate
into one for the validation. Should I just fire a function after the
3rd field that concatenates the 3 values, then pass that value to the
validation function? Or is there a better way?

I was also wondering if there was something I could find like an input
mask, but something that could just "overlay" on top of a regular text
box with one value which could give the appearance of having
separations for certain digits, in this case the first and last.
