Add HTML on an injected iframe
I'm currently developing a Toolbar from Googl开发者_StackOverflow社区e Chrome. Basically it's a toolbar that i'm injecting in every web pages by using a Content-Script. Technically the toolbar is materializd by a iframe that include all the components like button, dropMenu,... Here is the script you make this :
// Take down the webPage
document.getElementsByTagName('body')[0].style.marginTop = '39px';
var body = $('body'),
toolbarURL = chrome.extension.getURL("yourtoolbar.html"),
iframe = $('<iframe id="YourToolbarFrame" scrolling="no" src="'+toolbarURL+'">');
// Insertion
body.append(iframe);
// Effect
$("#YourToolbarFrame").hide().fadeIn(800);
But right now i'm trying to add some component on this iframe for example a button but it didn't work...
var yt = $("#YourToolbarFrame");
var newButton = $('<a href="javascript:openInstantMessage()"><input type="image" src="images/pop.ico" name="InstantMessage" width="23" height="23"></a>');
yt.append(newButton);
The body of the iframe look like this :
<body>
<div class="default">
// COMPONENTS
</div>
</body>
Hope someone can provide me some help ! :)
You have to wait until the iframe loaded. E.g.:
iframe.load(function() {
var newButton = ...;
$(this).contents().find('body').append(newButton);
}).appendTo('body');
Not sure how Chrome handles the same-origin policy for content scripts though.
Since you're using jQuery, you could try using
$('#YourToolbarFrame').contents().find('body').append(newButton);
Or if you don't want to append to the body directly, use any other element in the find() statement.
加载中,请稍侯......
