[英]Getting an error while updating form state using mutator react final form
i am trying to update the values in the form state using react final form mutators by writing function below我正在尝试通过在下面编写 function 来更新 state 形式的值
const setProjectSelectedMutator = ([value], formState, tools) => {
tools.changeValue(formState, () => value && value.isSelectedInProject === true);
};
and then i am calling that mutate function like as below,然后我称之为变异 function 如下所示,
if (!once) {
if (
form &&
values.spaceType.mechanicalData[mappedLibrarySourceArray] &&
values.spaceType.mechanicalData[mappedLibrarySourceArray][index]
) {
// values.spaceType.mechanicalData[mappedLibrarySourceArray][
// index
// ].isSelectedInProject = true;
form.mutators.setProjectSelectedMutator(
values.spaceType.mechanicalData[mappedLibrarySourceArray][index].isSelectedInProject
);
setOnce(true);
}
}
i would like to set the boolean to true using the mutator function like as i am setting the same(mentioned in commented code) and getting an error like mutate is not a function
.我想使用 mutator function 将 boolean 设置为 true,就像我设置相同(在注释代码中提到)并得到一个错误,如
mutate is not a function
I am new to react final forms and could any one please suggest any idea or suggestion on this issue.我是对最终 forms 做出反应的新手,任何人都可以就这个问题提出任何想法或建议。
Thanks in advance提前致谢
I think you forgot the second parameter that has the name of the field.我认为您忘记了具有字段名称的第二个参数。 I'ved added the
"SOME NAME"
string to your code.我已将
"SOME NAME"
字符串添加到您的代码中。
const setProjectSelectedMutator = ([value], formState, tools) => {
tools.changeValue(formState, "SOME NAME", () => value && value.isSelectedInProject === true);
};
