如果与 id javascript 匹配，则显示从 object 中选择的数据

Question

var myData=[{id: 655, permissionType: "book", instructorControlled: "", batchId: -1, title: "PAckagebook1", …},{id: 643, permissionType: "book", instructorControlled: "", batchId: -1, title: "PR book", …}]

如果匹配特定的 id，则单独显示数据 object。

Answer 1

使用查找方法

var myData=[{id: 655, permissionType: "book", instructorControlled: "", batchId: -1, title: "PAckagebook1", …},{id: 643, permissionType: "book", instructorControlled: "", batchId: -1, title: "PR book", …}]    
var myItem=myData.find(item=>item.id===655);
console.log(myItem);

Answer 2

 var myId = 643; // Some id you want to select by var myData = [ {id: 655, permissionType: "book", instructorControlled: "", batchId: -1, title: "PAckagebook1"}, {id: 643, permissionType: "book", instructorControlled: "", batchId: -1, title: "PR book"} ] let book = myData.find(obj => obj.permissionType === "book" && obj.id === myId) console.log(book)
