Highlighting a phone number on a web page for firefox add-on

Question

I am trying to develop a Firefox add-on using the documentation provided by the MDN. My regex works well when tested on a sample HTML page. But, the problem occurs when developing an add-on. Following is my code which is saved by the name my-scripts.js.

$("body:first").each(function(){
// Create a REGEX Expression to detetc a phone number
var regex =/\+\d{0,3}[-.\s]?\(?\d?\)?[-.\s]?\s?\d{1,4}[-.\s]?\d{1,9}[-.\s]?\d{5}/g;
var text = $(this).html();
text = text.replace(regex, "<a href=\"javascript:;\">$&</a>");
$("body:first").html(text);
});

Following is the main Javascript file called main.js.

var pageMod = require("sdk/page-mod");
var { MatchPattern } = require("sdk/util/match-pattern");
var pattern = new MatchPattern("http://example.com/*");
var self = require("sdk/self");
pageMod.PageMod({
contentScriptFile: [self.data.url("jquery-1.11.0.js"), self.data.url("my-script.js")]
});

My regex is perfect, but doesn't detect numbers on a given web page

Examples

+111111111111
+11 (1) 111 11 11111
+11 (1) 111 11-11111
+11 111 11 11111
+11 (1) 1111 111111111
+11111111111111
+11 1111 111111111

Answer 1

The (lower level) match pattern API is built into the (higher level) PageMod API in the form of the include property in the constructor. The only reason the match-pattern module is linked to in the PageMod docs is so that you have an idea of how the matching strings work.

So if want your add-on to be applied to "http://example.com/*", main.js should look like:

var {data} = require("sdk/self");
var pageMod = require("sdk/page-mod");
pageMod.PageMod({
  include: "http://example.com/*",
  contentScriptFile: [data.url("jquery-1.11.0.js"), data.url("my-script.js")]
});

If I misinterpreted that (the match-pattern lines were in there for another reason), and you want your regex to be applied to every page, use include: '*'.
