Properties: bindload
Note: triggered when the picture is loaded, event.detail = {height, width}

Legal value of mode

Value: scaleToFill
 Description: in zoom mode, the image is scaled without maintaining the aspect ratio, so that the width and height of the image are fully stretched to fill image Element. The default value is 320 full width px,High 240 px

Value: aspectFit
 Description: zoom mode, keep the aspect ratio to zoom the picture, so that the long edge of the picture can be fully displayed. In other words, the picture can be displayed completely. Ensure that the long side of the picture is displayed, which is generally used when making a rotation picture

Value: aspectFill
 Description: zoom mode, keep the aspect ratio to zoom the picture, and only ensure that the short edge of the picture can be fully displayed. In other words, the picture is usually complete only in the horizontal or vertical direction, and will be intercepted in the other direction. Keep the short side displayed and use it less

Value: widthFix
 Note: in zoom mode, the width remains unchanged, the height changes automatically, and the aspect ratio of the original image remains unchanged

Value: heightFix
 Note: in zoom mode, the height remains unchanged, the width changes automatically, and the aspect ratio of the original image remains unchanged

4. swiper (applet rotation chart)

1 rotation diagram outer container swiper

2. Each rotation item: wiper - item

3. There is a default style for the wiper label

1 width 100%
2 height 150px
    image There are default widths and heights 320 * 240
3 swiper Height cannot be supported by content

4 find out the width and height of the original drawing, and set the width and height for the swiper

Original width and height 1125 * 352 px
swiper width/ swiper height =Width of original drawing /Height of original drawing
swiper height swiper width* Height of original drawing/Width of original drawing
height: 100VW * 352 / 1125

autoplay automatic rotation
interval modify the rotation time
circular convergence rotation
Indicator dots display indicator pager indexer
Indicator color the unselected color of the indicator
Indicator - active color indicates the color of the indicator when it is selected


Equivalent to a hyperlink in the web, a tag
There will be line breaks in the applet, which is the biggest difference from the a tag in html

open-type Legal value of

navigate corresponding wx.navigateTo or wx.navigateToMiniProgram Function of
redirect corresponding wx.redirectTo Function of

Use restrictions

  1. The user needs to confirm that the jump starts from version 2.3.0. Before jumping to other applets, a pop-up window will be added uniformly to ask whether to jump. The user can jump to other applets only after confirmation. If the user clicks cancel, fail cancel will be called back.
  2. The number of other applets that each applet can jump to is limited to no more than 10. Starting from version 2.4.0 and the specified date (to be determined), if the developer submits the new version of applet code, if it uses the function of jumping to other applets, it needs to declare the list of applets to jump in the code configuration, which is limited to no more than 10, otherwise it will not pass the audit. The list can be updated when the new version is released, and dynamic modification is not supported. See configuration for configuration method. When calling this interface, the jumped appId must be in the configuration list, otherwise the callback fail appId "${appId}" is not in navigateToMiniProgramAppIdList.

6. Rich text

1. tip: nodes Not recommended String Type, performance will decline.
2. tip: rich-text Mask events of all nodes within the component.
3. tip: attrs Property is not supported id ,support class . 
4. tip: name Attribute case insensitive.
5. tip: If you use an untrusted HTML Node, the node and all its children will be removed.
6. tip: img Tags only support network pictures.
7. tip: If used in custom components rich-text Component, then only the of the custom component wxss Style pair rich-text Medium class take effect.
