[jira] [Updated] (CB-5025) WP7 localStorage.getItem unexpected
behaviour.
[ https://issues.apache.org/jira/browse/CB-5025?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Elvedin Hamzagic updated CB-5025:
---------------------------------
Description:
Javascript for WP7 localStorage.getItem returns string 'undefined' when specified key exists and value is undefined. This scenario can be reproduced by adding some key/value to localStorage, then removing it.
The actual line in code in getItem function, which produce this behaviour, is:
retVal = window.unescape(decodeURIComponent(this._result));
The problem is that decodeURIComponent return string 'undefined' when input is undefined, and this should be fixed somehow like this:
retVal = this._result ? window.unescape(decodeURIComponent(this._result)) : this._result;
