Lodash＆React，无法访问局部变量

Question

I'm having an issue with lodash in react. I've got the following code at the beginning of my render function. I get the value of layout from this.state & then on each layout object in the array, I set static as the inverse of the boolean property isEdit. However, I've tried everything and for some reason, I cannot access isEdit within my lodash function. It's undefined... I cannot figure out what I'm doing wrong, so any help would be appreciated.

public render() {
   const { isEdit, size } = this.props;
   const layout = this.state.layout.slice();
   _.forEach(layout, (x) => {
     x.static = !isEdit;
   });
   .....

Answer 1

Do you mean, all static property on layout are set to be true ? B'cos

!undefined would be true .

Also can you set defaultProp for your isEdit prop, just to be sure.
