Javascript behaves different with IOS6

[naqviak]

Hi

I have an iPad app in store called Mygazine Daily. The app is showing strange behavior in IOS6. The issue is narrowed down to this


I am not getting proper results when a execute a javascript in UIWebView using stringByEvaluatingJavaScriptFromString


Here is the string that works with IOS5

NSString *scriptString = @" function paging(){ var div1 = document.getElementById('page1').style; div1.height = window.innerHeight + 'px !important'; var columnWidth = window.innerWidth - 100; div1.webkitColumnWidth = columnWidth +'px !important'; div1.webkitColumnGap = '0px'; window.scroll(1000000,0); var result = window.pageXOffset/window.innerWidth + 1; return Math.ceil(result);} paging();";

Here is what my desired function is

function paging(){
var div1 = document.getElementById('page1').style; 
div1.height = window.innerHeight  + 'px !important';
var columnWidth = window.innerWidth - 100;
div1.webkitColumnWidth = columnWidth +'px !important';
div1.webkitColumnGap = '0px';
window.scroll(1000000,0);
var result = window.pageXOffset/window.innerWidth + 1;
return Math.ceil(result);}
paging();";

I have added alert() under different locations and this is what I found -
alert(div1.height) returns 840px under IOS5.1 but nothing under IOS6



Please help me understand what is different in IOS6

I'm not much of an expert with iOS but I would suggest looking in the iOS dev center
