lodash

问题 I have been trying to restructure the following flat array (participations, see below) to a more organized tree form, so that i can use Tree grid component of syncfusion. I have tried using the .reduce() function. but it seems i cannot make the correct strucutre. I have also tried lodash to group them by unique id. anyways here is what someone in this platform has helped to move forward: The Starting array participations is below. The names of some properties need to be renamed as well. /

问题 I have below this nested object I need to create an array using this object containing keys . And if keys are object then it should use .dot syntax. and if it is an array then it should give me key.0.keyName . Is it possible to do so? Output [ "AllowIPNPayment", "AllowOnlinePayment", "MetaData.CreateTime", "MetaData.LastUpdatedTime", "CustomField.0.DefinitionId", "CustomField.0.Name", "CustomField.0.Type", ... ] What I have tried is just ugly and does give me expected result. If it is

问题 In my code i have created one array called array1. In this array i have listed multiple objects. I want to filter out array1 objects values as unique and need to group ids with their respective values. I have added my code here, Array1 var array1 = [ { value:"A", id:1 }, { value:"B", id:1 }, { value:"C", id:2 }, { value:"B", id:5 }, { value:"A", id:2 }, { value:"A", id:1 } ]; the result which i want, [ { group:"A", groupIds:[1, 2] }, { group:"B", groupIds:[1, 5] }, { group:"C", groupIds:[2] }

问题 I am trying to check the following for empty values using lodash: data.payload{ name: "" } My code: import isEmpty from 'lodash.isempty'; if (isEmpty(data.payload)) { The above is false, how can I validate for empty values? I have this code in my helper: export const isEmpty = some(obj, function(value) { return value === ''; } ); In my action I have if (isEmpty(data.payload)) { I get an error, ReferenceError: obj is not defined but I am passing the object... 回答1: If you want to use isEmpty()

问题 I'm looking for an efficient way to replace the values within an object if they match a certain pattern. var shapes = { square: { attr: { stroke: '###', 'stroke-width': '%%%' } }, circle: { attr: { fill: '###', 'stroke-width': '%%%' } } } For instance, i'd like to be able to replace all '###' patterns with a colour for a specific shape: var square = replace(shapes.square, { '###': '#333', '%%%': 23 }); var circle = replace(shapes.circle, { '###': '#111', '%%%': 5 }); Which would allow me
