html - How to use regex to validate a text box in jquery? -


This question seems to be repeated to someone but it is not. This script was working perfectly well, till this morning, but it now works oddly. I have tried several suggested ways to change the code, such as removing the second part and if! = "True" but if there is no luck, check the situation.

jquery 

  $ ("# controlButton"). Click (function () {var SHPname = $ ("# fname") Val (); var textfieldmask = /^[az\.ss-] {2,} $ /; /// Check full name if (SHPname. Length {0} {var testname = textfieldmask.test (SHPname); warning (testname); if (testname == "true") {var tstnm = "ok"; alert (tstnm);} other {warnings (" Enter the full name! "); $ ('# Fname'). (); False return;}} {Alert (" Please enter a name "); $ ('# fname'). Focus (); Back; }});   
  HTML   
  & lt; Label class = "required" = "name" title = "enter your name" & gt; & Lt; Input type = "text" id = "fname" name = "fname" /> receiver's name & lt; / Label & gt; & Lt; Label = "formsubmit" class = "nocontent" & gt; & Lt; An id = "controlButton" href = "#" class = "progress-button" & gt; & Lt; P id = "btntxt" & gt; Save & lt; / P & gt; & Lt; Img id = "loadergif" src = "../images/loader-cart.gif" width = "30" height = "14" alt = "" /> & Lt; / A & gt; & Lt; Strong> Note: & lt; / Strong> Item marked & lt; Img src = "picture / required gif" alt = "required marker" width = "12" height = "12" /> Required fields are & lt; / Label & gt; The strange part is that the first warning I have is "true", but the code runs! = "True" and enter alerts full name! Why is this happening? Please help me in it.   
 
 
 This is working in a Jsfiddle try  testname == true  Keep it but without  ""   
  $ ("# controlButton") Click (function () {var SHPname = $ ("# fname"). Val (); var text filemask = /^[az\.ss-] {2,} $ /; /// Check full name if (SHPname .length & gt; 0) {var testname = textfieldmask.test (SHPname); alert (testname); if (testname == true) {var tstnm = "ok"; warning (tstnm);} other {warning ("complete" Enter the name! "); $ ('#fname'). Focus (); // return false; do you get this return in any way? If you do not need it}} else {alert (" Please enter a name "); $ ('# fname'). Focus (); // right return; here itself}});

Can anyone help me in solving this problem. #include "mpi.h" int main (int argc, char * argv []) Float dir = -90; Int rank, nanoprakash; MPI_Status status; MPI_Init (& amp; argc, & argv); MPI_Comm_rank (MPI_COMM_WORLD, & amp; Rank); MPI_Comm_size (MPI_COMM_WORLD, & amp; numprocs); If (rank == 0) {/ / data to begin / / (dest = 1; dest ...

python - Apply coupon to a customer's subscription based on non-stripe related actions on the site -

I can not find anything in the source about using coupons after subscribing to a user's plan. Is it possible to use a coupon to credit a user's membership after initial subscription? If not, what is the best option? Specifically, I want to give a user 100% coupon for that month, when they take 5 [site specific actions]. This is possible, but may not be the best idea. Coupons are currently applied to the stripe, then apply again at the customer level and each client can have a single coupon. So if you are already offering discounts to the coupon, then the customer who is currently in the present will also give up. It also means that if you are using a recently-added multiple subscription capacity, then all of the user's subscription will be ready for the month. Coupons can be set to "Once", only once (as the only name) can be used by any customer, so if this credit can earn more than once, You will have to maintain a 100% discount coupon continuousl...
