Map to JavaScript in HTML

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

Usage

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

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

Then, you can use the MapToJavaScriptHTML trait to insert your text from a map,

use std::collections::BTreeMap;

use map_to_javascript_html::MapToJavaScriptHTML;

let mut map = BTreeMap::new();

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

let text = map.to_javascript_html("_text");

assert_eq!("_text['hello']='Hello world!';_text['other keys']='Hello world!';_text['welcome']='Welcome to my website.';", text);

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

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

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

Methods suffixed with _to_string, _to_vec, _to_writer can be used to generate HTML.

There are also methods prefixed with to_javascript_html_with_keys which can be used with keys to filter the output.

use std::collections::BTreeMap;

use map_to_javascript_html::MapToJavaScriptHTML;

let mut map = BTreeMap::new();

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

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

assert_eq!("_text['hello']='Hello world!';_text['welcome']='Welcome to my website.';", text);
