javascript - Get text of span without ID -


i'm trying piece of text span line has not id. using xcode , swift 3.

here's line:

<span class="name">peter red</span>

i tried not work:

var name = webview.evaluatejavascript("document.queryselector('.name').innerhtml")         print("name \(name)")

i tried using .innertext, .textcontent , outertext console prints name ()

the evaluatejavascript(_:completionhandler:) instance method expects 2 parameters.

func evaluatejavascript(_ javascriptstring: string,        completionhandler: ((any?, error?) -> void)? = nil)

you missing completionhandler, run once script evaluation completes or fails.

try following:

 webview.evaluatejavascript("document.queryselector('.name').innerhtml") { (name, error) in         if error == nil {            print("name \(name)")         }     }

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m
