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?
I am trying to take a form input field and take what was entered and grab the first 8 character of what was entered and then submit that to a form instead of what was entered.
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.
i try to make a dynamic input text on table, and it can work well, but now i have problem when i try to delete a row, the counter (number) can't work well...this script for add dynamic textfield, it work well..

I'm making a dynamic div in a page but I'm having some doubts:-I have an input text field and i need to get it's position (left andtop) to make the div appear near this input. $.(':INPUTNAME').css('left') returns me zero like 'top' does.Is there a way to get left/top position from a static input text field
I have been looking for the past 2 days for a script that I can add and delete table rows.
I have found a lot but so far all of them add an input field but I desperatly need a textarea or ideally a section of input fields.
I have tried to change the code from input to text area but none of them worked.
Have you come across to a similar script.
I would appreciate any contributions.
What I am trying to do is a page where the user will add their employees details so we can order business cards for them. So I have fileds such as, Name, Tel Num, Email, Cell etc.
i,m trying to make a map who show me as position A and a target adress as point B.I have made it so i can choose adress a and adress b from a dropdown but i want to automaticly load my position as possition A then choose position B from a dropdownlist. How can i do this ?
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:
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".
I have URLs as follows. [URL] I need a function which can retrieve substring from the above URLs. The substring should be upto the 2nd occurence of '/' as follows. [URL]
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.
I am looking for a function that will replace last occurence of a substring from a string: tmpStr: xxx, yyy, zzz, sss, The desired outcome: xxx, yyy, zzz and sss (ie: remove last letter and then replace last occurrence of ",") The string can differ,
* xxx, * xxx, yyy, * xxx, yyy, zzz,
Do anyone of you have a neat fuction for that? I will be so happy for all input!
