Confirmed in trunk. Also, when the alert() is active the body element will contain the following innerHTML: <script> var x = new Date(); alert('foo'); document.write('Date: ' + x + '<br>'); </script>Date: Fri Sep 25 2009 13:23:25 GMT+0200 (CEST)<br><script> var x = new Date(); alert('foo'); document.write('Date: ' + x + '<br>'); </script>Date: Fri Sep 25 2009 13:23:26 GMT+0200 (CEST)<br>hallo hallo using the following snippet: #include <QtGui> #include <QWebView.h> int main(int argc, char **argv) { QApplication a(argc, argv); QWebView w; w.setHtml("<html><body><script>\n" "var x = new Date();\n" "alert('foo');\n" "document.write('Date: ' + x + '<br>');\n" "</script>hallo</body></html>\n"); w.show(); return a.exec(); }

Would be nice to have API for setting the default timeout. Especially for slower embedded devices.

Ping? Should this still be marked r+ and in the pending-commit list? There has been no action on this bug in over a month and a half...

Pong. It depends on bug 30879, which I need to write a LayoutTest for first.

Comment on attachment 42209 [details] [Qt] Use the default timeout interval for JS as the HTML tokenizer delay for setHtml() Clearing r+ since this patch depends on another bug to be landed first.

Should we backport this patch and the one in the depending bug into the branch?
