Question

im developing uiwebview in my app.
this UIWebView displays HTML5 pages and has javascript which access local db and displays lists of menu.

Problem is that i need to copy this database from app’s document directory and paste it to safari/databases folder..so that my javascript file can access this db and display list of files.

however no success in copying file from document folder to safari/Databases folder
here is my code:

    NSString *databasepath=[NSString stringWithFormat:@"~/Library/%@/%@",@"safari",@"databases"];

    NSFileManager *fileManager = [NSFileManager defaultManager];
    NSError *error;

NSString *resourcePath = [[NSBundle mainBundle] pathForResource:@"sfa.db" ofType:nil];
[fileManager copyItemAtPath:resourcePath toPath:databasepath error:&error];

Any help will b appreciated.
Thanks in advance.

1) I want javascript to connect with existing sqlite3 database located in my app’s document directory.

OR

I solved my problem using function stringByEvaluatingJavaScriptFromString
here is my code:

in my model:

-(void)webViewDidFinishLoad:(UIWebView *)webView {
//getMenuItems is fetches items from database
    [self getMenuItems];
//array items converted to string seperated by ","
     NSString *string = [[arr valueForKey:@"description"] componentsJoinedByString:@","];

//load is javascript function
    NSString *str=[NSString stringWithFormat:@"load('%@');",string];

[web stringByEvaluatingJavaScriptFromString:str]; 
}

in my html

   function load(example_array){
        var example_array=example_array.split(",");
    var select = document.getElementById("ddlMenu");

        for(i=0;i<=example_array.length-1;i++) {
        select.options[select.options.length] = new Option(example_array[i], i);
    }

    }
