I have JavaScript that contains this code:
$("input:checked").length
After returning, click the button in the browser, this code is $ ("input: checked"). length; does not work in opera. Is there anything I can do?
Basically I need to check if two radio buttons were checked or not
<script> $(document).ready(function () { $("#signup").button(); $("#signup").click(function () { alert($("#bb input:checked").length); if ($("#bb input:checked").length == 2) { $("#signup").val("1"); } }); }); </script> @using (Html.BeginForm()) { <div id="wrapper"> <div id="bb"> <div id="rbl1" class="rbl1"> <input type="radio" id="rb11" name="radio-b1" value="1"/><label for="rb11" class="radio">Everyday</label> <input type="radio" id="rb12" name="radio-b1" value="2"/><label for="rb12" class="radio">Saturday</label> </div> <div id="rbl2" class="rbl2"> <input type="radio" id="rb21" name="radio-b2" value="1"/><label for="rb21" class="radio">One</label> <input type="radio" id="rb22" name="radio-b2" value="2"/><label for="rb22" class="radio">Two</label> </div> </div> </div> <button name="submit" id="signup">Sugn up</button> }
The first time it works well in all browsers, after the radio buttons have verified that I submit my form at this time, everything is fine. But then I just checked what happened if I go back to the browser history and submit the form again, so that all browsers are fine except opera, it fails on this $ ("# bb input: checked") code line. Length == 2) and did not give any details.
Before I used jQuery 1.5.1, now I upgraded to 1.5.2 and still the same question. Detailed example code updated, full html code sent here http://sourcepod.com/puvmmz30-4571
Perhaps there is something wrong with the history of Opera.
Somehow I can set the value of $ ("# signup"). val ("1"); or check if the list of radio stations ("#bb input: checked") is selected, and the Opera story did not understand this.
