如何获得onclick事件

Question

代码：

NSURLRequest *_request =  [[NSURLRequest alloc] initWithURL:[NSURL URLWithString:@"http://i.fx-func.com/h5/lp/16484/1322570745"]];
[myWebView loadRequest:_request];
 <div class="more"><a data-action="fullArticle" href="javascript:;" onclick="function:
 {'action':'edit', 'id': 222, 'info': '2344543534'}">words</a></div>
 </div>

我想要

"function: {'action':'edit', 'id': 222, 'info': '2344543534'}"
