Encode string for URL (angular)

Question

I'm trying to encode a string that's pretty complex, so that I can include it in a mailto:

Component:

<a href="mailto:[email protected]?subject='Hello'&{{body}}"> 

TS:

import { HttpParameterCodec } from "@angular/common/http";  let body = encodeValue('This is the example body\nIt has line breaks and bullets\n\u2022bullet one\n\u2022bullet two\n\u2022bullet three') 

When I try to use encodeValue, I get "cannot find name encodeValue.

How would be best to url-encode body?

Answer 1

HttpParameterCodec : is a codec for encoding and decoding parameters in URLs( Used by HttpParams).

If you need to encode Url you can use the below:

encodeURI assumes that the input is a complete URI that might have some characters which need encoding in it.

encodeURIComponent will encode everything with special meaning, so you use it for components of URIs, such as:

var textSample= "A sentence with symbols & characters that have special meaning?"; var uri = 'http://example.com/foo?hello=' + encodeURIComponent(textSample); 

Answer 2

Both encodeURI() and encodeURIComponent() will work, while there are some differences:

var set1 = ";,/?:@&=+$";  // Reserved Characters  var set2 = "-_.!~*'()";   // Unescaped Characters  var set3 = "#";           // Number Sign  var set4 = "ABC abc 123"; // Alphanumeric Characters + Space    console.log(encodeURI(set1)); // ;,/?:@&=+$  console.log(encodeURI(set2)); // -_.!~*'()  console.log(encodeURI(set3)); // #  console.log(encodeURI(set4)); // ABC%20abc%20123 (the space gets encoded as %20)    console.log(encodeURIComponent(set1)); // %3B%2C%2F%3F%3A%40%26%3D%2B%24  console.log(encodeURIComponent(set2)); // -_.!~*'()  console.log(encodeURIComponent(set3)); // %23  console.log(encodeURIComponent(set4)); // ABC%20abc%20123 (the space gets encoded as %20)
