Click the .trash_can button to hide the selected li tag 
![[Web front-end] Node.js quick start](https://img.php.cn/upload/course/000/000/067/662b5d34ba7c0227.png)
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
Use splice(), such as products_mes.splice(subscript, 1) to delete an item in the array
var index = products_mes.indexOf(data);
products_mes.splice(index,1);
data: for the selected object
