[英]modify object property and add it to object as nested properties
我正在使用来自 x <input>
字段的用户输入创建和填充 object。 到目前为止,我已经成功地创建了 object 并使用用户输入填充它。 但是,我坚持下一步。
我想抓取和修改用户输入,并使用逗号将其分隔为嵌套属性进行拆分。
这可能是一项简单的任务,但我想不出一个可行的解决方案。 我怎样才能做到这一点? (不确定我对自己的解释有多好,所以我发布了一个所需输出的示例)
html:(可能比 2x2 更多的输入字段)
<input type="text" name="test_1.Title" class="tests">
<input type="text" name="test_1.String" class="tests">
<input type="text" name="test_2.Title" class="tests">
<input type="text" name="test_2.String" class="tests">
function objectMaker() {
function objectSubs(obj, keys, value) {
let key = keys.shift()
if (keys.length) {
obj[key] = obj[key] || {}
objectSubs(obj[key], keys, value)
return
}
obj[key] = value
}
function grabTestData(){
var inputs = document.getElementsByClassName('tests');
var testObject = {}
Object.keys(inputs).forEach(i => {
let inputName = inputs[i].getAttribute('name');
objectSubs(testObject, inputName.split('.'), inputs[i].value)
})
}
grabTestData()
}
当前 object:
var testObject = {
tests1: {
title: "random title",
string: "somestring, other string, and anotherString",
},
tests2: {
title: "other random title",
string: "thisString, thatString, a String there",
},
}
所需的 object:
var testObject = {
tests1: {
title: "random title",
string: {
substring1: "somestring",
substring2: "other string",
substring3: "and anotherString",
},
},
tests2: {
title: "other random title",
string: {
substring1: "thisString",
substring2: "thatString",
},
},
}
var testObject = {
tests1: {
title: "random title",
string: "somestring, other string, and anotherString"
},
tests2: {
title: "other random title",
string: "thisString, thatString, a String there"
}
};
testObject.tests1.string = testObject.tests1.string.split(",");
testObject.tests2.string = testObject.tests2.string.split(",");
console.log(testObject);
此代码的 output 是:
{
tests1: {
title: 'random title',
string: [ 'somestring', ' other string', ' and anotherString' ]
},
tests2: {
title: 'other random title',
string: [ 'thisString', ' thatString', ' a String there' ]
}
}
如果您想制作 function 以将 object 转换为您想要的格式:
function splitStrings(obj) {
Object.values(obj).forEach(val => val.string = Object.fromEntries(val.string.split(',').map((e, i) => ["substring"+(i+1), e.trim()])));
return obj;
}
Object.values
的值来获取{ title, string }
对象的数组forEach
object,将.string
设置为 object,通过将字符串中的每个逗号分隔值转换为格式[substringN, value]
的条目创建演示:
var testObject = { tests1: { title: "random title", string: "somestring, other string, and anotherString", }, tests2: { title: "other random title", string: "thisString, thatString, a String there", }, } function splitStrings(obj) { Object.values(obj).forEach(val => val.string = Object.fromEntries(val.string.split(',').map((e, i) => ["substring"+(i+1), e.trim()]))); return obj; } splitStrings(testObject); console.log(testObject);
如果你想要一个子字符串数组,你可以这样做:
function splitStrings(obj) {
Object.values(obj).forEach(val => val.string = val.string.split(',').map(e=>e.trim());
return obj;
}
