React15-querybuilder NPM

react15-querybuilder

这个 React 组件是在React QueryBuilder v1.3.8 基础上又新增了新的功能该项目使用了 React 15，如果要在基于 React 16 以上的版本的项目中使用，可以使用 React QueryBuilder

Getting Started

npm install react15-querybuilder --save

Usage

import QueryBuilder from "react15-querybuilder";

const fields = [
  { name: "firstName", label: "First Name" },
  { name: "lastName", label: "Last Name" },
  { name: "age", label: "Age" },
  { name: "address", label: "Address" },
  { name: "phone", label: "Phone" },
  { name: "email", label: "Email" },
  { name: "twitter", label: "Twitter" },
  { name: "isDev", label: "Is a Developer?", value: false },
];

const dom = <QueryBuilder fields={fields} onQueryChange={logQuery} />;

function logQuery(query) {
  console.log(query);
}

API

<QueryBuilder /> is the only top-level component exposed from this library. It supports the following properties:

fields (Required)

{name:String, label:String}

The array of fields that should be used. Each field should be an object with {name:String, label:String} |

operators (Optional)

{name:String, label:String}

The array of operators that should be used. The default operators include:

[
  { name: "=", label: "=" },
  { name: "!=", label: "!=" },
  { name: "<", label: "<" },
  { name: ">", label: ">" },
  { name: "<=", label: "<=" },
  { name: ">=", label: ">=" },
  { name: "contains", label: "Contains" },
  { name: "beginsWith", label: "Begins With" },
  { name: "endsWith", label: "Ends With" },
  { name: "doesNotContain", label: "Does Not Contain" },
  { name: "doesNotBeginWith", label: "Does Not Begin With" },
  { name: "doesNotEndWith", label: "Does Not End With" },
  { name: "null", label: "Null" },
  { name: "notNull", label: "Not Null" },
  { name: "in", label: "In " },
  { name: "notIn", label: "Not In" },
];

combinators (Optional)

{name:String, label:String}

The array of combinators that should be used for RuleGroups. The default set includes:

[
  { name: "and", label: "AND" },
  { name: "or", label: "OR" },
];

controlElements (Optional)

React.PropTypes.shape({
  addGroupAction: React.PropTypes.func, // React.component
  removeGroupAction: React.PropTypes.func,

{
  label: React.PropTypes.string, //"+Group"
  className: React.PropTypes.string, //css classNames to be applied
  handleOnClick: React.PropTypes.func, //callback function to invoke adding a <RuleGroup />

  level: React.PropTypes.number //The level of the current group
}

removeGroupAction: By default a <button /> is used. The following props are passed:

{
  label: React.PropTypes.string, //"x"

}

addRuleAction: By default a <button /> is used. The following props are passed:

  level: React.PropTypes.number //The level of the current group
}

combinatorSelector: By default a <select /> is used. The following props are passed:

{
  options: React.PropTypes.array.isRequired, //same as 'combinators' passed into QueryBuilder
  value: React.PropTypes.string, //selected combinator from the existing query representation, if any
  className: React.PropTypes.string, //css classNames to be applied
  handleOnChange: React.PropTypes.func, //callback function to update query representation
  rules: React.PropTypes.array, //Provides the number of rules already present for this group
  level: React.PropTypes.number //The level of the current group
}

getOperators (Optional)

function(field):[]

This is a callback function invoked to get the list of allowed operators for the given field

onQueryChange (Optional)

function(queryJSON):void

This is a notification that is invoked anytime the query configuration changes. The query is provided as a JSON structure, as shown below:

{
  "combinator": "and",
  "rules": [
    {
      "field": "firstName",
      "operator": "null",
      "value": ""
    },
    {
      "field": "lastName",
      "operator": "null",
      "value": ""
    },
    {
      "combinator": "and",
      "rules": [
        {
          "field": "age",
          "operator": ">",
          "value": "30"
        }
      ]
    }
  ]
}

controlClassnames (Optional)

This can be used to assign specific CSS classes to various controls that are created by the <QueryBuilder />. This is an object with the following properties:

{
    queryBuilder:String, // Root <div> element

    ruleGroup:String, // <div> containing the RuleGroup
    combinators:String, // <select> control for combinators
    addRule:String, // <button> to add a Rule
    addGroup:String, // <button> to add a RuleGroup
    removeGroup:String, // <button> to remove a RuleGroup

    rule:String, // <div> containing the Rule
    fields:String, // <select> control for fields
    operators:String, // <select> control for operators
    value:String, // <input> for the field value
    ignoreCase:String, // <input type=checkbox> for the field ignoreCase
