How to get spring mvc controller model key value inside javascript?

Question

I am using a spring mvc controller. Inside controller i am putting some value lets say string inside model. Now i would like to retrive that value or lets just say print that value inside a javascript. How do i do it? Here is my controller class. I am adding "movie" as key. Now i want to display that name of the movie inside java script (Not inside JSP. However Inside JavaScript) ``` @Controller @RequestMapping("/movie") public class MovieController { @RequestMapping(value="/{name}", method = RequestMethod.GET) public String getMovie(@PathVariable String name, ModelMap model) { model.addAttribute("movie", name); return "list"; } } ``` here is my JSP ``` //I want to print movie name inside java script not inside jSP body tag.

Movie Name : ${movie}

//When i print here its working fine. ```

Accepted Answer

Use this:

```
var movie_name = "${movie}";
```

instead of:

```
var movie_name = ${movie};
```

When using `${movie}`, the value gets placed on the page without quotes. Since I'm guessing it's a string, Javascript requires strings be surrounded by quotes.

If you checked your browser's console, you probably would've seen an error like `Unexpected identifier` or `___ is not defined`.
