// JS splice method for remove items from an array.
// JS findIndex method for find the index of the element which you want to delete. 

昨天我也遇到过类似的问题,但是jquery的问题。现在使用vuejs,我想模型绑定实际上更简单,这样所有选定的行都将被推送到一个数据属性。然后单击delete,循环遍历所有选定的id或密钥,并将它们从您的存储中删除,或者调用后端api或您的数据属性,就像您在这里所做的那样,例如。

data: () => ({
    selected: [],
    projects: {/*...content in here */},
});

methods: {

   delete() {
       this.selected.forEach(function(project) { // project here is just the index of the selected in the projects array
           projects.splice(project, 1);
      });

      this.selected = []; // don't forget to empty selected
   }
}

Data table 与 store 的对象数组

我们也可以用 地图 为了得到 index 存储阵列 并使用以下方法将其移除:

REMOVE_OBJECT_FROM_ARRAY: (state, payload) => { let i = state.someArrayofObjects.map(item => item.id).indexOf(payload.id); state.someArrayofObjects.splice(i, 1); }

这里,那个 id MUTATION ,我们也只能通过 身份证件 payload . 在这种情况下,我们可以这样做:

REMOVE_OBJECT_FROM_ARRAY: (state, payload) => { let i = state.someArrayofObjects.map(item => item.id).indexOf(payload); state.someArrayofObjects.splice(i, 1); }
