javascript - Tornado doesn't send Ajax response to client -

-

After submitting the form, the Tornado server does some tests and sends a response to the client, which should show in the current page. Warning .

An empty HTML page is provided instead with a Jason response, but not a as a warning the current page where the form was submitted Was there.

When submitting the form it is sent via post to / dh (DataHandler)

this is Jquery: / P> 

  $ Post ("/ dh", function (data, status) {warning ("data:" + data + "\ n status:" + status);}, "json");

Turtado code: 

  Class database: Behinddaler: Deaf Post (self): # Checks are made with the form data received dupinfo = {'Tel': Duptel, 'name': dupname} self.write (json.dumps (dupInfo, default = json_util.default)) self.finish ()

How to Return

After the "Warning" statement, add return false . This disables the default handling of the browser of the POST event. The default behavior of the browser is to navigate to the new URL, and you want to stop it.

HTML/CSS - Automatically set height width from background image? -

-
Long time ... I do not think it's possible, but I'm shocked before! I tag anchor tags, all of which are background images, all 300px wide but their height is all the difference, is it really set to do without typing altitude? Is it to set the dimensions of BG URL? Thank you! I do not think people understand - my mistake is to hurry the question. Here is the code as an example: # ago -1 {width: 300px; Height: 410px; Background: url ('/ image-1.jpg');} # East -2 {width: 300px; Height: 420px; Background: url ('/ image-2.jpg');} # Pre-3 {width: 300px; Height: 430px; Background: url ('/ image-3.jpg');} # Pre-4 {width: 300px; Height: 440px; Background: url ('/ image-3.jpg');} & lt; A href = "#" id = "ex-1" & gt; & Lt; / A & gt; & Lt; A href = "#" id = "ex-2" & gt; & Lt; / A & gt; & Lt; A href = "#" id = "pre-3" & gt; & Lt; / A & gt...

c - What is the address of buf (the local variable in the main function)? -

-
I had exercise with programming in c or classes and I followed the question: Is Buf (local variable in main function)? Either enter the answer in hexadecimal format (like 0x 8 "digits" 0-9 or A-F, 0xbfff0014) or in decimal format. Note here that we want the address of the buff, not its content. The code looks like this: int main (int argc, char * argv []) {while (1) {four buff [1024] = {0}; Int r; .... I then started the code and put the built code in the buff [1024] line and in Typed Gdb p & amp; Buf and it gives me results: 0xbffff0f0 But when I use it in this quiz it gives me the result that this value is wrong. My question is this: Is this the name of the Buff variable (P & E)? Or if not, why not? Exercise is done on the virtualbox machine, so I think everyone should be the same address There is no correct numerical answer, the address may vary from one time to another, it is a programming drill that you say the following three...
