lodash

问题 I'm trying to add debouncing with lodash to a search function, called from an input onChange event. The code below generates a type error 'function is expected', which I understand because lodash is expecting a function. What is the right way to do this and can it be done all inline? I have tried nearly every example thus far on SO to no avail. search(e){ let str = e.target.value; debounce(this.props.relay.setVariables({ query: str }), 500); }, 回答1: The debounce function can be passed inline

问题 I have a JSON response like this: { id_order: '123123asdasd', products: [ { description: 'Product 1 description', comments: [ { id_comment: 1, text: 'comment1' }, { id_comment: 2, text: 'comment2' } ] } ] } How can I remove, with lodash, one object which has an id_comment that is equal to 1, for example? Tried using _.remove without success. Solution https://jsfiddle.net/baumannzone/o9yuLuLy/ 回答1: You can use _.remove inside an forEach using an object as the predicate: _.forEach(obj.products,

问题 I am trying to return the matching ids in this array of objects: const arr = [{id:1,name:'Harry'},{id:2,name:'Bert'}] const arr2 =["1"] How can I return just the id with value 1 in arr? 回答1: Lodash Probably the most concise working solution would be using the lodash _.intersectionBy but that would require your arr2 array to contain an object with an id : const arr = [{id:1,name:'Harry'},{id:2,name:'Bert'}] const arr2 =[{id:1}] // <-- object with the `id` const result = _.intersectionBy(arr,
