window.location.indexOf not working in Javascript
alert, indexof, javascript, string
Solution
`window.location` is an accessor property, and getting its value gives you an object, not a string, and so it doesn't have an `indexOf` function. (It's perfectly understandable that people sometimes think it's a string, since when you set its value, the accessor property's setter accepts a string; that is, `window.location = "some url";` actually works. But when you get it, you don't get a string.)
You can use `window.location.toString()`, `String(window.location)`, or `window.location.href` to get a string for it if you like, or use any of its various properties to check specifics. From the link, given example url `http://www.example.com:80/search?q=devmo#test`:
- `hash`: The part of the URL that follows the # symbol, including the # symbol. You can listen for the hashchange event to get notified of changes to the hash in supporting browsers. Example: `#test`
- `host`: The host name and port number. Example: `www.example.com:80`
- `hostname`: The host name (without the port number). Example: `www.example.com`
- `href`: The entire URL. Example: `http://www.example.com:80/search?q=devmo#test`
- `pathname`: The path (relative to the host). Example: `/search`
- `port`: The port number of the URL. Example: `80`
- `protocol`: The protocol of the URL. Example: `http:`
- `search`: The part of the URL that follows the ? symbol, including the ? symbol. Example: `?q=devmo`
For instance, for your quoted example, you might check `window.location.hostname === "localhost"`.
Problem
Below is what I have. ``` var myString = "http://localhost:8888/www.smart-kw.com/"; alert(myString.indexOf("localhost")); ``` This give me alert... however if I change `var myString = "http://localhost:8888/www.smart-kw.com/";` to `var myString = window.location;`, it won't work (I don't get alert). ``` var myString = window.location; alert(myString.indexOf("localhost")); ```
