Writing data in files at client machine using javascript in chrome

Hi,

I want to write a file using javascript at client machine using chrome.
Chrome doesnt allow activeX object. however there are add ons to counter the issue.
The requirement is writing a file without using addon.
Kindly suggest.

The reason that Chrome does not allow ActiveX is because it is a massive security risk. You are not going to be able to read or write any data to a user's computer without getting the user to disable a vast array of security protocols.

Please explain what you are trying to accomplish and maybe we can suggest an alternative to this.

Hi,
Suppose i am placing an order in website and the data is stored on the server. After submission of the data on server i want the same data to be stored at client machine in json file in json format using javascript.

I need to know why you are storing the data locally on the user's computer. It would be quite easy to create an automatic download for the user.

Hi,
I will tell you my apllication functionality:
1) User shops for items and they are placed in shopping cart.
2) That detail is stored in browser memory. But now i want the backup of the same data in client machine in json format. SO that by chance if browser cache is cleared user has a restore option.

Use a cookie or HTML5 local storage instead.

Hi

Can you kindly suggest how to use HTML5 local storage.
And if i clear the cache in the browser all the data will be lost. I want a permanent storage for the same.
