TangWei updated WEEX-233:
-------------------------
    Description: 
Hi, I'm Tw93(侑夕) from [Fliggy|https://www.fliggy.com/], I'd like to discuss the 
enhancements about component, let it take over where we can't implement through 
weex.
h2. Target

{{<web>}} is used to display web content that specified by src attribute in 
weex page,We also can use webview module to control WebView behavior such as 
goBack, goForward and reload.

But it's not enough in most businesses，I think a more enhanced web component 
should have the following:
 * Support to send messages from Weex to a html in component.
 * Support to send messages from a html in component to Weex.
 * Support to render html source.

Previously, component was an island that only rendered a remote url, but 
enabled it to communicate through the context native to the webView. Then I'm 
going to describe the solution that I came up with.
h2. My solution
