Name

string::escape_javascript Escape Strings for JavaScript

Synopsis

string::escape_javascript(string [, quote: true])
escape_javascript(string [, quote: true])
string::escapeJavascript(string [, quote: true])
escapeJavascript(string [, quote: true])

Description

The escape_javascript function escapes a string for safe use within JavaScript code. It ensures that special characters are properly escaped to prevent syntax errors or injection issues.

Characters escaped include:

• Double quote (") → \"
• Backslash (\) → \\
• Control characters (newline, carriage return, tab) → \n, \r, \t, etc.
• Unicode characters → \uXXXX (where XXXX is the Unicode code point in hexadecimal)

If the quote parameter is true (default), the returned string is wrapped in double quotes.

Parameters

• string (string, required) The text to escape.

• quote (boolean, optional) If true (default), enclose the escaped output in double quotes. If false, return only the escaped string without wrapping quotes.

Examples

res={{
    a := qq("'\n\t\rabcéé");
    escape_javascript(a); "\n";

    a := "<script>console.log('allo');";
    escape_javascript(a); "\n";

    a := "'test'";
    escape_javascript(a); "\n";
    escape_javascript(quote:false, a); "\n";
}};

Returns:

res = "\"'\n\t\rabcéé"
"<script>console.log('allo');"
"'test'"
'test'
