HTML 代码
functionpayResult(str){
if(str =='true'){
...
}
}
OC 代码
NSString * jsStr = [NSString stringWithFormat:@"ocContent('%@','%@')",@"参数1",@"参数2"];
[_wkWebView evaluateJavaScript:jsStr completionHandler:^(id_Nullableresult,NSError*_Nullableerror) {
}];
这么写的过程中总是崩溃，原因是js中可能有alert，但是oc中的方法没有进行操作，方法如下：
- (void)webView:(WKWebView*)webView runJavaScriptAlertPanelWithMessage:(NSString*)message initiatedByFrame:(WKFrameInfo*)frame completionHandler:(void(^)(void))completionHandler{
UIAlertController *alert = [UIAlertController alertControllerWithTitle:message message:message preferredStyle:UIAlertControllerStyleAlert];
[alertaddAction:[UIAlertAction actionWithTitle:@"知道了" style:UIAlertActionStyleCancel handler:^(UIAlertAction * _Nonnull action) {
completionHandler();
}]];
[self presentViewController:alert animated:YES completion:nil];
}
