I am told by Google Page Test speed to remove the script below from my HTML <head> tag because it blocks the rendering of the page. From my research this script load a library or something like this. Is it wise to remove it? Can I do this without consequences on running other JavaScript on my page?
https://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js
I believe the test page is telling you to put the script tag in the bottom, but still within, the html/body tags. The reason for this is the browser will load that file before continuing on with the rest of the page, thus briefly blocking any content yet to be loaded. You're also using a CDN so if there is a bad network connection then you can expect for there to be perceived performance issues. Inserting the script tags at the bottom yields better perceived performance.
As to whether or not you need jQuery, depends on if your are utilizing it or not, as #Dave Newton said.

I am trying to build a site using React.js which when you click on the link to find more info, a sidebar appears with the additional information. The problem that I am having is that when the sidebar appears, I want the url to change as well. It is similar to a sliding page transition but the sliding page is a sidebar instead that only covers half the page. I hope that makes sense. Any help in which direction I can go in to investigate if this is possible will be a great help!
Website page navigation layout
If you want to change the url I suspect using withRouter will be your best bet. You can get access to history and push in the url you want. Cool design, man.
You'd want to push in the new url in the history on click of the link btw. Also as I can see by the first comment that showed up always try googling first cause people are assholes on this site and will just shit on you for not googling this since it is pretty common to use the history and change the url.
Good luck!

When open this website: http://codeera.net/adlink/
in any browser except Google chrome
work without issues,
But when open this website in Google chrome I get a HTML page
without CSS, JS and images (all of external links)
it is because AdBlock, if you disable it everything will be ok.
and just try to rename your title as "Ad" will activate AdBlock, I guess.
AdBlock looks for elements or attributes with 'ad' keyword to block them.

I am looking for a solution to convert html element and it's content into image object which I could send with email attachment. Most of the solutions and JavaScript libraries I've found are based on Canvas element (HTML5), but as IE8 doesn't support it - those solutions can't be used. Does anyone have any solutions which could be supported for all browsers from ie8?
I must tell you that I have researched a lot on this and I must tell you that html2canvas is the best among all to get the images of html content.
So you better change your browser.
I am just saying this so that you wont waste much of your valuable time.
Use Html2Canvas for taking screen shot .Its very easy .. just include the html2canvas js files.. you will get from Here
and some simple codes . Refer this -> Click Here
NOTE : Please download the latest release of html2canvas , now its very much improved in new realease , for eg:
1.supports transform images.
2.By far gives better quality images than before.

Looking for something like Viewer.js but for loading a separate HTML document.
So I want something that has pagination concepts, and this doesn't have javascript in it, just CSS and HTML. It's not cross domain, it's fed back from a Web API.
Not sure why there's downvotes.
Why don't you use iframe?. It should do exactly what you need - load a separate HTML into your web page.
You cannot create something like Viewer.js because you can have problems with loaded JS and CSS, that is why iframe is a safety option (and probably the only one)

I am wanting to load javascript and css files via a resource loader. I was originally using LabJs but I found YepNope more elegant and easier to work with in my scenario. However I am finding it devastatingly slow, which is odd as apparently it is comparable to LabJs in speed on most things.
One thing I do have are Etags which I am sure will slow everything down as its still requesting from the server rather than just working off the client cache.
Anyway there isnt much outside of the main YepNope site, and they havent released a new version with the fixes on their issues list in a while, so I was wondering what other options there are out there...
My requirements are:
Needs to load Css and Javascript
Needs to do them all in parallel
Can be loaded via Javascript
I wish YepNope was a bit more active but wanted to weigh up the other options...
I would throw require.js up for consideration. It will dynamically add script and css tags to the <head> so it works nicely asynchronously. It will also optimize all your js into one file so if you project is like mine you'll have dozens of js files in development (I think we have about 100) but only 1 for production.
The only thing I haven't got working yet is the optimization of the css files though apparently it has been done.
Good luck
