我正在尝试将GPS坐标传递给方法调用setIOSNativeAppLocation
。我在下面有以下代码,但我收到此错误:
A JavaScript exception occurred"
UserInfo={WKJavaScriptExceptionLineNumber=1, WKJavaScriptExceptionMessage=
ReferenceError:
Can't find variable: setIOSNativeAppLocation, WKJavaScriptExceptionSourceURL=
http://mywebsite.com, NSLocalizedDescription=
A JavaScript exception occurred, WKJavaScriptExceptionColumnNumber=24})
我不确定它是否与语法或其他任何内容有关。如果有人知道我做错了什么,我会非常感激。
func webView(_ webView: WKWebView, didFinish navigation: WKNavigation!) {
if(myCurrentLoc != nil){
let lat = myCurrentLoc.coordinate.latitude
let lon = myCurrentLoc.coordinate.longitude
print(lat);
print(lon);
webView.evaluateJavaScript("setIOSNativeAppLocation(\(lat), \(lon));") { (result, error) in
guard error == nil else {
print("there was an error")
print(error)
return
}
}
}
}
答案 0 :(得分:0)
我认为这可以为您提供帮助-我们在此处传递参数的方式。
我们应该将其放在单引号中('\(lat)','\(lon)'),否则它将像变量一样。
func webView(_ webView: WKWebView, didFinish navigation: WKNavigation!) {
if(myCurrentLoc != nil){
let lat = myCurrentLoc.coordinate.latitude
let lon = myCurrentLoc.coordinate.longitude
print(lat);
print(lon);
webView.evaluateJavaScript("setIOSNativeAppLocation('\(lat)', '\(lon)');") { (result, error) in
guard error == nil else {
print("there was an error")
print(error)
return
}
}
}
}
