Question

I am making changes to a section of an app that uses a js coffee script to navigate to a different page of the site. I would like to append the current get request to the new url.

Is there an easy way of accessing the get request in the coffee script?

I know in javascript you can use window.location to get the full url, but how do you do it in coffeescript.

Answer 1

Please have a look at the following code

paramValue = (name) ->
  name = name.replace(/[\[]/, "\\[").replace(/[\]]/, "\\]")
  regexS = "[\\?&]" + name + "=([^&#]*)"
  regex = new RegExp(regexS)
  results = regex.exec(window.location.href)
  unless results?
    ""
  else
    results[1]

The argument to the method is the name of the param of the param whose value you require. It will return the corresponding value of that particular url

window.location.href will return the URL of the current page
