-------------------------------
Summary: [proposal] Support to detect the feature compatibility of
weex
Key: WEEX-54
URL: https://issues.apache.org/jira/browse/WEEX-54
Project: Weex
Issue Type: New Feature
Components: JSFM
Affects Versions: 0.15
Reporter: Hanks Zhang
Assignee: sospartan
Priority: Minor
h2. Background
Because Weex support to extend components and modules, so the host environment
will be very different. Weex needs a mechanism to detect whether a feature is
supported in the current environment.
h2. API Design
{code:javascript}
weex.supports(condition : String) : Boolean | Null
{code}
* param: a formatted string. @{type}/{name}
* return value:
* supported -> true
* unsupported -> false
* unclear -> null
h2. Usage
{code:javascript}
// Detects whether the embed component is supported
weex.supports('@component/embed')
// Detects whether the picker module is supported
weex.supports('@module/picker')
// Detects whether the dom.getComponentRect method is supported
weex.supports('@module/dom.getComponentRect')
{code}
