Question

I need to pass some values from a textbox on a certain page, as a query string, and then receive it in another page.

The thing is want to send the escape characters for new line of the textbox (\r\n)

button.onclick = function () {
    window.open('receiver.aspx?Device=' +
                          document.getElementById('myTextbox').value);
};

Is that possible/allowed?

Answer 1

Use encodeURIComponent:

button.onclick = function () {
    window.open('receiver.aspx?Device=' +
                 encodeURIComponent(document.getElementById('myTextbox').value));
};

It:

Encodes a Uniform Resource Identifier (URI) component by replacing each instance of certain characters by one, two, three, or four escape sequences representing the UTF-8 encoding of the character
