How can I get the email address in a URL to appear on my webpage with javascript or HTML with a website built on Ruby on Rails?

Question

How can I get the email address from a URL to appear on my webpage with javascript or HTML with a website built on Ruby on Rails?

I have a URL like this:

http://dance.danceninjas.com/thanks-so-good?cf_uvid=1ce505f1e32477b73a15a514962e25b2&email=test324@gmail.com

And I want to pull the email address from the URL into the webpage so I can say:

Please verify your email is correct: <EMAIL_HERE>

I know that with WordPress I would use the PHP code:

echo $_GET["email"];

But apparently that won't work with websites built with Ruby on Rails.

I am using ClickFunnels to build my website, which means I have the ability to add Javascript into my footers and add snippets of custom HTML code.

Does anyone know how I can accomplish this?

Answer 1

If I understand correctly, ClickFunnels acts as a hosting and front-end construction platform that only gives you access to your page only through:

• editing content
• assigning pre-made templates
• placing client-side JavaScript code

There's nothing Rails-specific you can use here. That would imply a lot of potential for security breaches. Execution of arbitrary Ruby can be done right, it's just rarely needed and thus rarely done.

That said, PHP-like solutions such as $_GET["email"]; won't work by principle. @rorofromfrance's answer has its right sides, but you can't make use of this because you don't own the platform and you can't modify the templates . It's not bad service design , there are some big advantages of this, the biggest of which is caching : a static page without any server-side processing can be placed in cache entirely and served through a CDN that can handle crazy amounts of traffic and stay up.

SO the solution is offloading that action for the client's browser. You pass parameters in a query string . This string is accessible through JavaScript ( window.location.search ), in raw format, like:

"cf_uvid=1ce505f1e32477b73a15a514962e25b2&email=test324@gmail.com"

That said, it should be split into keys and values before being used. And there are plenty of solutions for this under this question . Pick the one you like most.

您将需要使用Ruby语言（如果可以），然后将允许您访问如下URL参数：

params[:email]
