javascript - 自動入力 UIWebView

Question

私は周りを見回しており、次のような自動入力用のコードをたくさん見つけました。

 - (void)webViewDidFinishLoad:(UIWebView *)webView
{
//For Authentication
NSString *savedUsername = @"Bapu";
NSString *savedPassword = @"Bapu123";

if (savedUsername.length != 0 && savedPassword.length != 0)
{
    //create js strings
    NSString *loadUsernameJS = [NSString stringWithFormat:@"var inputFields = document.querySelectorAll(\"input[type='text']\"); \
                                for (var i = inputFields.length >>> 0; i--;) { inputFields[i].value = '%@';}", savedUsername];
    NSString *loadPasswordJS = [NSString stringWithFormat:@"var inputFields = document.querySelectorAll(\"input[type='password']\"); \
                                for (var i = inputFields.length >>> 0; i--;) { inputFields[i].value = '%@';}", savedPassword];

    //autofill the form
    [webView stringByEvaluatingJavaScriptFromString: loadUsernameJS];
    [webView stringByEvaluatingJavaScriptFromString: loadPasswordJS];
}
}

それが私の.mにあるものですが、webViewに行くと、フィールドは空白のままです。なぜそれが満たされないのかについての手がかりはありますか?

それが役立つ場合、私が入力しようとしている Web サイトは sis.ocsarts.net で、関連するコードは次のとおりです。

input type="text" size="20" name="UserName" value=""  onkeydown="if (event.keyCode==13) { document.frmLogin.submit(); return false; };"

と

input type="password" size="20" name="Password"  onkeydown="if (event.keyCode==13) { document.frmLogin.submit(); return false; };"

私の FirstViewController.m の完全なコードは次のとおりです。

    [webView stringByEvaluatingJavaScriptFromString: loadUsernameJS];
    [webView stringByEvaluatingJavaScriptFromString: loadPasswordJS];
