以正确的方式加载html以使stringByEvaluatingJavaScriptFromString工作

Question

我正在尝试使stringByEvaluatingJavaScriptFromString正常工作。 我确定我将html文件加载错误，只是看不到我做错了。

-(void)viewDidLoad
{   
// Load the index.html file as a string from the file system
  NSString *path = [[NSBundle mainBundle] pathForResource:@"index" ofType:@"html"];
  NSString *html = [[NSString alloc] initWithContentsOfFile:path encoding:NSUTF8StringEncoding error:nil];

// Load/pass it in to webView
  [webView loadHTMLString:html baseURL:[[NSBundle mainBundle] bundleURL]];
  [super viewDidLoad];
}

我将javascript事件传递/发送到index.html：

-(void)webViewDidFinishLoad:(UIWebView *)webView
{
[webView stringByEvaluatingJavaScriptFromString:@"displayName('name');"];
}

我做错了什么？

Answer 1

这是我为此功能编写的代码。

NSString *fullURL = @"url";
NSURL *url = [NSURL URLWithString:fullURL];
NSURLRequest *requestObj = [NSURLRequest requestWithURL:url];
[webView loadRequest:requestObj];

完成加载

-(void)webViewDidFinishLoad:(UIWebView *)webViews {
NSString *testString = [webView stringByEvaluatingJavaScriptFromString:@"document.getElementById(\"[ID]\").innerHTML;"];
    [webView loadHTMLString:testString baseURL:nil];
}
