List of methods for the selectorQuery object:

Method parameter description inobject Component reference below detailed introduction selectselector reference below detailed introduction selectAllselector reference below detailed introduction selectViewport reference below detailed introduction exec [callback] reference below detailed introduction selectorQuery.in (component)

The basic library 1.6.0 is supported, and the lower version needs to be compatible.

Change the selection of the selector to within the custom component component. (initially, the selector selects only the nodes in the page scope and does not select nodes in any custom component. )

Sample code:

Component ({queryMultipleNodes: function () {var query = wx.createSelectorQuery (). In (this) query.select ('# the-id') .boundingClientRect (function (res) {res.top / / the upper boundary coordinates of # the-id nodes in this component}). Exec ()}) these are all the contents of the article "how to use selectorQuery developed by Mini Program". Thank you for reading! I believe you will gain a lot after reading this article.
