[英]how to assign variables to an object for submitting the Data using reactjs?
我的目标是在提交数据时将变量分配给新对象。
这是提交时出现的对象数组:
experience: [
{
Organisation: "",
ID: "",
From: "",
To: "",
Skills: []
},
{
Organisation: "",
ID: "",
From: "",
To: "",
Skills: []
}
]
但我希望对象应该是这样的:
{
organisationName: "",
id: "",
from: "",
to: "",
skills: []
}
我已经这样做了,但输出没有适当地出现在这个中。
handleSubmit = (e)=> {
e.preventDefault();
let obj = {
id: this.state.experience.map((item) => item.ID),
organisation: this.state.experience.map((item) => item.Organisation),
from: this.state.experience.map((item) => item.From),
to: this.state.experience.map((item) => item.To),
}
console.log("Object", obj)
}
任何人都可以帮我以正确的方式分配值吗?
使用Object.fromEntries
映射条目并在键上调用toLowerCase
会更容易:
const lowercaseKeys = obj => Object.fromEntries(
Object.entries(obj)
.map(([key, val]) => [key.toLowerCase(), val])
);
const obj = this.state.experience.map(lowercaseKeys);
如果您还需要用另一个替换特定键,请使用.replace
:
const lowercaseKeys = obj => Object.fromEntries(
Object.entries(obj)
.map(([key, val]) => [
key.toLowerCase().replace('organisation', 'organisationName'),
val
])
);
const obj = this.state.experience.map(lowercaseKeys);
