Try indexOf  if  foo indexOf  franky    gt   0              You can also try search  for regular expressions   if  foo search  franky    gt   0

Try this  it s shorter and works exactly as window location href   if  document URL indexOf  franky    gt  -1            also if you want to check the previous URL   if  document referrer indexOf  franky    gt  -1

You need add href property and check indexOf instead of contains   x000D   x000D   lt script src  https   cdnjs cloudflare com ajax libs jquery 3 3 1 jquery min js  gt  lt  script gt  x000D   lt script type  text javascript  gt  x000D      document  ready function     x000D      if  window location href indexOf  franky    gt  -1    x000D        alert  your url contains the name franky    x000D        x000D        x000D   lt  script gt  x000D   x000D   x000D

if  window location href indexOf  franky      -1    would do it  Alternatively  you could use a regexp   if   franky  test window location href

window location isn t a String  but it has a toString   method  So you can do it like this       window location  includes  franky     or   window location toString   includes  franky     From the old Mozilla docs      Location objects have a toString   method returning the current URL  You   can also assign a string to   window location  This means that you   can work with window location as if it   were a string in most cases    Sometimes  for example when you need   to call a String method on it  you   have to explicitly call toString

Use Window location href to take the url in javascript   it s a   property that will tell you the current URL location of the browser    Setting the property to something different will redirect the page    if  window location href indexOf  franky    gt  -1         alert  your url contains the name franky

document URL should get you the URL and   if document URL indexOf  searchtext      -1          found   else         nope

It will be a good practice if you convert your string to lower or uppercase as indexof   method is case sensitive  This will be if your search isn t case sensitive you can simply use indexOf   method without converting the orignal string to lowercase or uppercase  var string  location href  var convertedString  string toLowerCase     if convertedString indexOf  franky      -1        alert  quot url has franky quot      else       alert  quot url has no franky quot

You would use indexOf like this   if window location href indexOf  franky      -1          Also notice the addition of href for the string otherwise you would do   if window location toString   indexOf  franky      -1

The regex way   var matches     location href match  franky      a boolean value now   Or in a simple statement you could use    if  location href match  franky        I use this to test whether the website is running locally or on a server   location href match   192 168 localhost    1337     This checks whether the href contains either 192 168 or localhost AND is followed by  1337   As you can see  using regex has its advantages over the other solutions when the condition gets a bit trickier

I like to create a boolean and then use that in a logical if     kick unvalidated users to the login page var onLoginPage    window location href indexOf  login    gt  -1    if   onLoginPage      console log  redirected to login page      window location     login     else     console log  already on the login page

Regular Expressions will be more optimal for a lot of people because of word boundaries  b or similar devices  Word boundaries occur when any of 0-9  a-z  A-Z    are on that side of the next match  or when an alphanumeric character connects to line or string end or beginning   if  location href match      b   franky    b        If you use if window location href indexOf  sam    you ll get matches for flotsam and same  among other words  tom would match tomato and tomorrow  without regex   Making it case-sensitive is as simple as removing the i   Further  adding other filters is as easy as   if  location href match      b      franky bob billy john steve     b    i     Let s talk about     b     RegEx typically defines   as a word character so it doesn t cause a word boundary  We use this     b    to deal with this  To see if it either finds  b or   on either side of the string   Other languages may need to use something like  if  location href match      wxxx       franky bob billy john steve     wxxx     i     where xxx is a character representation  range or literal  of your language s alphanumeric characters    All of this is easier than saying   var x   location href    just used to shorten the code x indexOf  -sam-      x indexOf  -sam       x indexOf   sam       x indexOf   sam         and other comparisons to see if the url ends with it     more for other filters like frank and billy   Other languages  flavors of Regular Expressions support  p L  but javascript does not  which would make the task of detecting foreign characters much easier  Something like    p L   filters in any alphabet    p L
