jQuery Question

How can you check for a #hash in a URL using JavaScript?

I have some jQuery JavaScript code that I want to run only when there is a hash (#) anchor link in a URL. How can you check for this character using JavaScript? I need a simple catch-all test that would detect URLs like these:


  • example.com/page.html#anchor

  • example.com/page.html#anotheranchor



Basically something along the lines of:

if (thereIsAHashInTheUrl) {
do this;
} else {
do this;
}


If anyone could point me in the right direction, that would be much appreciated.

Answer

Simple:

if(window.location.hash) {
  // Fragment exists
} else {
  // Fragment doesn't exist
}
