Mindmap unable to support on IE

[jianzhang89]

Hi,

Thanks for sharing such a wonderful mindmap. The mindmap is unable to support for IE but able to be supported by chrome & firefox.
I am unable to troubleshoot what is the error?

file location: storage.js
SCRIPT5007: Unable to get value of the property 'getItem': object is null or undefined
script.js, line 463 character 116

return localStorage.getItem(key);

I not sure whether did u encounter the same problem as me.
Please save me

Regards
Jian Zhang

LocalStorage is not supported by your browser.
Which version of IE are you using? You need at least IE9 for the app to work. Even though IE8 came with support for LS it cannot handle tags. If you are on IE7 and below.. my condolences.

Hi richard,

Thanks for your immediate respond. I am running the mindmap using an iframe on c# asp.net environment.
The error regarding the localstorage is from IE9. I am required to run in an IE8 environment.
Is there any codes or configuration to be done to allow the mindmap to run in an IE8 environment? Or handle the tags?

Thanks

Well, I doubt it. However, in theory it is possible:

• One would have to remove the local storage code from the application
• Use some lib like excanvas to have canvas suport
• Fix all style issues that arise when using <IE9

I wouldn't recommend that, however. The app was not built to support older browsers, it is a prototype after all :)
