indexOf Multiple arguments

Question

var pathname = window.location.pathname;
if (! (pathname.indexOf('edit') > -1) ) {
  // Do stuff...
}

In the above example I am negating and only running the JS on pages that DO NOT include 'edit', I want to change it to accept multiple arguments, for example, "edit", "delete", "admin", "settings".

Whats the best way of doing this?

var pathname = window.location.pathname;

if (["edit", "delete", "admin"].some(x => pathname.indexOf(x) > -1)) {
    // ...
}

Without arrow function for older browsers

var pathname = window.location.pathname,
    isSpecialPath = ["edit", "delete", "admin"].some(function(x) { return pathname.indexOf(x) > -1; });

if (isSpecialPath) {
    // ...
}

Array.prototype.some(): The some() method tests whether some element in the array passes the test implemented by the provided function.

Nice, but uses modern features, so will depend on the browser (doesn't work in IE11) – freedomn-m Aug 23 '16 at 11:09

@freedomn-m `.some()` is available since IE9. And the arrow function is easy to replace with a "normal" function. – Andreas Aug 23 '16 at 11:11
Yes, I was referring to the `=>`, not `.some()`, just adding comment as a warning incase someone tried it and just got "Syntax error" and didn't know why. – freedomn-m Aug 23 '16 at 11:12
@freedomn-m I've added a version without an arrow function – Andreas Aug 23 '16 at 11:13

You can make a loop an see if anything is found and do what you want afterwards.

var pathname = window.location.pathname;
var names = ["edit", "delete", "admin", "settings"];
var found = false;

for( var i = 0; i < names.length; i++ ) {
    if( pathname.indexOf(names[i]) > -1 ) {
        found = true;
        break;
    }
}

if( !found ) {
    // do stuff
}

You can use a regular expression to test for multiple values, eg:

var pathname = window.location.pathname;

var textToSearchFor = /(edit)|(delete)|(ADDMORE)/;

if (path.match(textToSearchFor) == null) {
  //Entered Text not available
  //alert("Not available");
}
else {
   //Entered Text available
   //alert("Available");
}

You can try with this :

var pathname = window.location.pathname;
if((/edit|delete|admin|settings/i).test(pathname))
{
    console.log("exists");
}
else
{
    console.log("not exists");
}
