| 34 | <h1>Timeout test</h1> |
|---|
| 35 | |
|---|
| 36 | <p> |
|---|
| 37 | This test page tests the timeout functionality of dojo.io.script, and to make |
|---|
| 38 | sure that requests that time out get removed quickly. If the server response |
|---|
| 39 | is received after the script has been timed out, there should not be weird |
|---|
| 40 | errors as the browser tries to evaluate the responses after the desired time |
|---|
| 41 | period. |
|---|
| 42 | </p> |
|---|
| 43 | |
|---|
| 44 | <p>This test requires a server running PHP to work.</p> |
|---|
| 45 | |
|---|
| 46 | <p> |
|---|
| 47 | <p><strong>Firefox Oddity:</strong> Firefox |
|---|
| 48 | will print an error after the script response is received from the server:<br /> |
|---|
| 49 | <span style="color: red">dojo.io.script.jsonp_dojoIoScript1 has no properties</span> |
|---|
| 50 | This is bad because Firefox goes ahead and evaluates the script contents in the page's |
|---|
| 51 | JavaScript space (this happens even when I turn off Firefox Add-Ons). All other browsers |
|---|
| 52 | do not evaluate the script (given the weird Opera 9.22 behavior below). You can test this |
|---|
| 53 | by clicking the <b>Test for SuperXFooBarVariable</b> button after receiving the response |
|---|
| 54 | for timeout.php (check Firebug Net tab to see when request is received). All other browsers |
|---|
| 55 | show an error or show the "undefined" value for SuperXFooBarVariable, but Firefox will show its |
|---|
| 56 | value as being: "Oh no! SuperXFooBarVariable is defined (should not be for timeout case)". |
|---|
| 57 | |
|---|
| 58 | <p><strong>Opera Oddity:</strong> Opera 9.22 does not seem to trigger the timeout case, |
|---|
| 59 | but rather it waits for the server to send a response to the script before continuing past the |
|---|
| 60 | point where the script is added to the DOM? That seems wrong. Dynamic script tags are no longer |
|---|
| 61 | an async operation? |
