copied!<p>> I cannot encode the ampersands before the string is made due to the nature of this project</p> <p>Then you won't have a full-proof answer.</p> <p><a href="http://en.wikipedia.org/wiki/Query%5Fstring#URL_encoding" rel="nofollow noreferrer">Ampersands (<code>"&"</code>) separate query parameters in url query strings</a>. You can't have it both ways where some of your query parameter values contain un-escaped <code>"&"</code> and expect a parser based on this simple rule to know the difference.</p> <p>If you can't escape <code>"&"</code> as <code>"%26"</code> in each value component beforehand, then you can never <em>know</em> that the values you get are correct. The best you could do is: If the value to the right of an <code>"&"</code> and before the next <code>"&"</code> does <em>not</em> contain an equal sign <code>"="</code>, you append the value to the previous value read, or the empty string if this is the first value read.</p> <p>This requires a proper parser as JavaScript does not support lookahead regular expressions that could help you do this.</p> <p>Note however that an algorithm like that completely bypasses the spec. Presuming for a moment that the query string: </p> <pre><code>a=test&b=cats & dogs&c=test </code></pre> <p>is valid, technically that string contains <strong>4</strong> parameters: <code>"a"</code> (with a value of <code>"test"</code>), <code>"b"</code> (with a value of <code>"cats "</code>), <code>" dogs"</code> (with no value), and <code>"c"</code> (with a value of <code>"test"</code>).</p> <p>If you don't change the query string at the source (and properly escape the value component), you're just hacking in the wrong solution.</p> <p>Good luck.</p>
