Smart Substring
Sep 9, 2007If 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, 2005I'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, 2005Trying 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?

Jul 7, 2010what will be the regular expression for this line:

View 2 Replies View RelatedSubstring A Value For Display And Concatenate For Validation?
Feb 28, 2006I 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.
