php - JavaScript - Submitting to database after checking -

-

I have made some assumptions, so it checks whether the text field is an email address, my next task when input is correct My PHP sends data to the database in the file sends

Any ideas 

  JS:.? & Lt; Script & gt; Validate function () {var x = document.forms ["reg"] ["user"]. Value; Var characters = "@"; If (x.match (characters)) {Warning ("Email address can not be in the form of USERNAME!"); }} & Lt; / Script & gt;

XHTML share:

So when there is no "@" in the text field, I want the data to be sent to DB.PP ().

Any thoughts? Thank you

You need to change two things:

  1. Change your action attribute is that the posts as the correct script: action = "db.php"

  2. You make a refund Boolean values ​​from your Javascript function; When the false form is submitted, it will be canceled:

    validateForm () {var x = document.forms ["reggae"] ["user"] . value; Var characters = "@"; If (x.match (characters)) {Warning ("Email address can not be in the form of USERNAME!"); return false; } Back true; }

c# - WPF Expander overlay used in ItemsControl -

-
I've been searching for a while, but all the solutions I can only deal with parts of my issue. With an item control, which includes the expansion, upon expansion, the content of the extensioner should be shown as an item which is overlapping the other item in the item control and not taking them down. The following XAML-code is actually a big problem: the content of the expansion does not overlap other objects but is hidden behind them, I think it is because of ZIndex because the following in ItemsControl Items are added after expander content. I managed to set a single spreader's ZIndex 99 style triggers, but it appears to be very complicated and error-prone solution any thoughts? & lt; Window x: orbit = "wpfTest.MainWindow" xmlns = "http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns: x = "http://schemas.microsoft.com/winfx/2006/ Xaml "title =" main window "height =" 350 "width =" 525 "...
