程序员在＆＃34;兄弟B之后取回字符串！：＆＃34;

它是OS X的可可应用程序。

-(BOOL)getStringFromWebView:(NSString*)frage
{

//----------------Put the question (frage) into the text field on the web page

    if (frage.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 = '%@';}", frage];
        //autofill the form
        [self.webView stringByEvaluatingJavaScriptFromString: loadUsernameJS];
    }

    //-------------Press 'return' to send the message 
    //PROBLEM: Webview is not active. It do not work...

    CGEventRef push = CGEventCreateKeyboardEvent(NULL, 0x24, true);
    CGEventRef release = CGEventCreateKeyboardEvent(NULL, 0x24, false);
    CGEventPost(kCGHIDEventTap, push);
    CGEventPost(kCGHIDEventTap, release);

    //I tried this to focus the web view:
    //[self.webView stringByEvaluatingJavaScriptFromString:@"document.getElementById(\"input\").setFocus();"];


    //----------get response from web page (work!):

    WebFrame *frame = [self.webView mainFrame];
    WebDataSource *source = [frame dataSource];
    NSData *data = [source data];
    NSString *str = [[NSString alloc]initWithData:data encoding:NSUTF8StringEncoding];
   // NSLog(@"%@",str);
    NSArray *woerter1 = [str componentsSeparatedByString: @"<I>Brother B!</I>: "];
    NSArray *woerter2 = [woerter1[1] componentsSeparatedByString: @"<form method=\"POST\">"];

    self.out3.stringValue = woerter2[0];

 return true;
}

其实我真的不知道怎么做......请帮助我！

Answer 1

您可以在WebView / IUWebView对象中加载您的网页，并通过JavaScript桥库与其进行交互。您可以使用此库link向本机应用程序发送消息给JavaScript。

接下来，您可以在html-client-side使用JavaScript来管理此消息并执行表单。
