JS H5界面简单交互

摘要: H5 iOS交互

原生向H5传值的话，约定空方法进行接收

[self.webView stringByEvaluatingJavaScriptFromString:[NSString stringWithFormat:@"box(%d)",delegate.isLogined]];

相反：

webView代理方法里：

- (BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request navigationType:(UIWebViewNavigationType)navigationType {

}

截取当前发生行为的链接

NSString *requestString = [[request URL] absoluteString];

前端约定点击跳转链接进行判断是否允许发生跳转 或者跳回原生App

if( navigationType == UIWebViewNavigationTypeOther ) {

if ([requestString hasPrefix:[NSString stringWithFormat:@"%@/product_details/BuyPageCommon.aspx",BASE_URL]]&&delegate.isLogined) {

｝

}
