I'm thinking about writing a Chrome extension that will need to, on a certain dynamic page of a certain site, grab a few links and analyze the contents of the linked pages.
I actually don't know much about writing browser extensions, so I wanted to see if it was doable before I committed myself to learning how. I do know that extensions typically execute Javascript but I am unaware of how to get that sort of result with Javascript.
Use jquery ajax to fetch the content of other pages.
You can use jQuery and this plugin by James Padolsey to make a cross domain request; the plugin will return the page contents. You can then do something like this to get it into a jQuery object:
$.ajax({
url: 'http://example.com',
type: 'GET',
success: function(res) {
var contents = $(res.responseText);
}
});
With that contents object you can do anything you would do normally with a jQuery object, such as find(). For instance, if you wanted to get the title of the page, you could do:
$.ajax({
url: 'http://example.com',
type: 'GET',
success: function(res) {
var contents = $(res.responseText);
var title = contents.find('title').text();
}
});
