1. I don't know whether your so-called removal is deleted or hidden, if it is deleted, just execute the deletion method directly. If it is hidden, add status to each item, hidden or wx:if to determine whether it is displayed or not, and the data is docked with the background.

wx.showModal ({
title: 'prompt',
content: 'this is a modal pop-up window',
success: function (res) {

) 
if (res.confirm) {
  console.log('')
} else if (res.cancel) {
  console.log('')
}

}
})
look at the callback, and the user clicks OK to execute the upstairs answer.

after clicking, you can call a method to change the data,
such as
function delete (index) {

  list.splice(index,1);
  this.setData({list});

};
has some examples: https://github.com/meibin08/

render the data of your favorite list as an array. When you bind button events, you can pass the objects in this array, and then process a

in the array.

under this object, delete it or change the control variable, depending on your own business logic.

for example, if you use the wx:if, on the 1st floor to say wx:if= "{{item.isShow}}", you can change the isShow field of this object to false.
