reactjs – 提取/读取React propTypes

您可以以中间格式定义您的propTypes,从中生成您的propTypes静态.

var myPropTypes = {
  color: {
    type: 'oneOf',value: ['green','blue','yellow'],},};

function processPropTypes(propTypes) {
  var output = {};
  for (var key in propTypes) {
    if (propTypes.hasOwnProperty(key)) {
      // Note that this does not support nested propTypes validation
      // (arrayOf,objectOf,oneOfType and shape)
      // You'd have to create special cases for those
      output[key] = React.PropTypes[propTypes[key].type](propTypes[key].value);
    }
  }
  return output;
}

var MyComponent = React.createClass({
  propTypes: processPropTypes(myPropTypes),static: {
    myPropTypes: myPropTypes,});

然后,您可以通过MyComponent.myPropTypes或element.type.myPropTypes访问自定义的propTypes格式.

这是一个帮助,使这个过程更容易一些.

function applyPropTypes(myPropTypes,Component) {
  Component.propTypes = processPropTypes(myPropTypes);
  Component.myPropTypes = propTypes;
}

applyPropTypes(myPropTypes,MyComponent);
