cef注入js_cef注入js文件

思路很简单，在页面加载完成时，执行以下JS代码即可：

var v = document.createElement('script');

v.src='http://127.0.0.1:9526/cef.js';

document.body.appendChild(v);

cef.js文件内容：

alert('hello cef.js');

// 具体实现代码如下，重载OnLoadEnd即可

class SimpleHandler : public CefClient,

public CefDisplayHandler,

public CefLifeSpanHandler,

public CefLoadHandler {

public:

SimpleHandler();

~SimpleHandler();

// ...

virtual void OnLoadEnd(CefRefPtr browser,

CefRefPtr frame,

int httpStatusCode) OVERRIDE

{

frame->ExecuteJavaScript("alert('OnLoadEnd');", frame->GetURL(), 0);

const CefString js = "var v = document.createElement('script');v.src='http://127.0.0.1:9526/cef.js';document.body.appendChild(v);";

frame->ExecuteJavaScript(js, frame->GetURL(), 0);

}
