How to retrieve the DOM data from chrome extension? -

-

I have code to develop the Chrome extension.

manifest.json

background.js 

  debugger; Chrome.browserAction.setBadgeText ({text: "maskkkk"}; function doStuffWithDOM (domContent) {Console.log ("I received the following DOM content: \ n" + domContent);} Chrome.browserAction.onClicked.addListener (function (tab) {console.log ('this run will be bg creit jerk'); chrome Tabs.sendMessage (tab.id, {text: "report_back"}, Dustfood Dom);});

script.js 

  debugger; / * Listen for messages * / console.log ('content script'); Chrome.runtime.onMessage. AddListener (function (msg, sender, transmitted remittance) {/ * if the expected format is in the received message ... * / if (msg.text and (msg.text == "report_back")) {/ * specified callback Call on, web page / content to send / send as spam in the form of arguments (documents all [0] .outerHTML);}});

I clicked on the icon, so I did not see any kind of activity. What is the right procedure to get and manipulate DOM content from open tabs?

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...
