That is, they are typically not returned in the same order that they were assigned. Existing key-value pairs may be modified during enumeration, but inserting or removing keys may cause some items to be enumerated multiple times or not at all.</p> <p>Assuntos relacionados: <a href="For.htm">For-loop</a>, <a href="Object.htm#NewEnum">Object._NewEnum()</a></p> <p>Examples:</p> <pre class="NoIndent"><em>; Create some sample data.</em> obj := Object("red", 0xFF0000, "blue", 0x0000FF, "green", 0x00FF00) <em>; Enumerate!</em> enum := obj._NewEnum() While enum[k, v] t .= k "=" v "`n" MsgBox % t <em>; Requires <span class="ver">[AHK_L 59+]</span></em> For k, v in obj s .= k "=" v "`n" MsgBox % s </pre> </div> </body> </html>
