Map to JavaScript in HTML

This is a library for serializing a (hash) map to JavaScript code in HTML, usually for dynamically generating strings on web pages.

Example

In your HTML or templates to generate HTML, such as Handlebars, for instance,

<script>
var _text = {};
{{{text}}}
</script>

Then, you can use this crate to insert your text into JavaScript code in HTML,

extern crate map_to_javascript_html;

use map_to_javascript_html::hash_map_to_javascript_html;
use std::collections::HashMap;

let mut map = HashMap::new();

map.insert("hello", "Hello world!");
map.insert("welcome", "Welcome to my website.");
map.insert("other keys", "Hello world!");

let text = hash_map_to_javascript_html(&map, "_text", &["welcome", "hello"]);

After Handlebars replaces {{{text}}} with your text, the HTML will be,

<script>
var _text = {};
_text['welcome'] = 'Welcome to my website.';
_text['hello'] = 'Hello world!';
</script>

The key and the value used in a map must implement the Display trait.
