添加的目標和選擇事件：UIControlEventValueChanged，然後簡單地調用從選擇的JavaScript功能。

//set the selector for datePicker event 
[datePicker addTarget:self action:@selector(dateChanged) forControlEvents:UIControlEventValueChanged]; 
....... 
....... 
-(IBAction)dateChanged 
{ 
    ....... 
    ....... 
    //call the javascript function text=>data to show 
    NSString *string = [NSMutableString stringWithFormat:@"showTextFromNative(%@)", text];  
    [self.webviewOutlet stringByEvaluatingJavaScriptFromString:string]; 
} 


//javascript function in your html 
function showTextFromNative(text) 
{ 
.... 
....///Do what ever you want to show in webview 
.... 
}
