 ## Attributes
-
-- `auto-play`: <boolean> `true` | `false`. This value determines whether the slides plays automatically after the page rendering finished. The default value is `false`.
-- `interval`: <number> millisecond. This value determines time interval for each page displayed in slider.
-- `index`: <number> . This value determines the  index of current shown slide. The default value is `0`.
-- `offset-x-accuracy {float}`: set the scroll event trigger precision, precision value represents the rolling distance of a page width ratio.
-- `show-indicators {boolean}`: set whether to display indicator
-- `infinite {boolean}`: set whether the page in the slider can be scrolled
-- `scrollable {boolean}`: set whether slider pages can be switched by sliding gestures
-- `keep-index {boolean}`: set whether to maintain the index of the page after the data changes
-- `forbid-slide-animation {boolean}`: <sup class="wx-v">0.21+ & iOS only</sup>. On iOS animation is enabled by default, and here we provide this attribute to shutdown animation on iOS.
