点击.trash_can按钮隐藏选中的li标签

Answer 1

Create an empty array to store the index of the data you need to delete, such as delProds

Add ng-click to your checkbox
When triggered, push the index of this product to the delProds array when it is judged to be true
When it is false, delete it from delProds

Then when you click the delete button, just delete all the data with the corresponding serial number

Answer 2

Use splice(), such as products_mes.splice(subscript, 1) to delete an item in the array

Answer 3

$scope.remove = function(idx) {
    $scope.products_mes.splice(idx, 1);
}

Answer 4

var index = products_mes.indexOf(data);
products_mes.splice(index,1);
data: for the selected object

Answer 5

splice
