问题
I'm using pretty much the this process oulined here to allow javascript to call objective c from my iPad app:
http://www.stevesaxon.me/posts/2011/window-external-notify-in-ios-uiwebview/
My javascript code that I'm injecting into the page is:
<script type="text/javascript">;
window.external =
{
'Set_A': function(s) { document.location = 'qms://Set_A?param=' + s; },
'Get_A': function(s) { document.location = 'qms://Get_A'; },
'Set_B': function(s) { document.location = 'qms://Set_B?param=' + s; },
'Get_B': function(s) { document.location = 'qms://Get_B'; },
'Set_C': function(s) { document.location = 'qms://Set_C?param=' + s; },
'Get_C': function(s) { document.location = 'qms://Get_C'; },
'Get_Version': function(s) { document.location = 'qms://Get_Version'; }
};
</script>;
And the javascript in the html code that calls the above method for initialization is:
<html>
<body>
...
<script type="text/javascript">
Get_Version();
Set_A(true);
Set_B(false);
Set_C(true);
<script>
</body>
</html>
In the above html the only method that gets called in Objective C is the last method Set_C(true);
Thanks.
