primefaces jsf p:ajax event keyup ignore arrow keys -

-

I have an input text field that has a valid button. When you click the valid button, it verifies some backend and a green check mark appears next to the button. I would like that the green check marks disappear, when the price changes, and the focus is not lost now because there is a test button on the page which I validate / disable. Therefore, incident = "blurry" or even "change" will not work because they can click on the button when the input text field changes. I used the key and it works great, but the arrow keys and tabs etc ... trigger this event and I do not want them. 

  & lt; H: inputText id = "baseURL" style = "width: 425px;" value = "# {View.baseURL}" & gt; & Lt; P: Ajax event = "Keys" update = "valid icon: edit list format: testUrlButton" listener = "# {View.resetValidation ()}" /> & Lt; / H: inputText>

I see JQuery options for this, but I need to work with JSF and Primacy tags.

What I have seen here:

The solution will be closer to: / P> 

  & lt; H: inputText id = "BaseURL" style = "width: 425px;" Value = "# {View.baseURL}" onkeyup = "If (event.keyCode! = #### _YOUR_KEYS _ ####) incorrect return; " & Gt; & Lt; P: ajax event = "keyball" execution = "@ this keycode" update = "valid mark: edit list format: testUrlButton" listener = "# {View.resetValidation ()}" /> & Lt; / H: inputText>

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...
