如何使用 javascript 中的输入表单更新对象数组 属性 的值？
How do I update an array of object property value with input form in javascript?
我目前正在学习 node.js、express.js 和把手
我有 2 个表单，添加表单和编辑表单以制作 blog/news 类型的页面
/添加项目：
app.get('/addproject', function(req, res) {
res.render('addproject', { title: "Add Project", apActive: true, active: "active" })
})
app.post('/addproject', function(req, res) {
const projectImage = req.body.projectImage;
const projectTitle = req.body.projectTitle;
const projectContent = req.body.projectContent;
const projectDate = {
startDate: req.body.projectStartDate,
endDate: req.body.projectEndDate
}
const projectTech = {
checkHtml: req.body.checkHtml,
checkNode: req.body.checkNode,
checkCss: req.body.checkCss,
checkReact: req.body.checkReact
}
let month = [
"Jan",
"Feb",
"Mar",
"Apr",
"May",
"Jun",
"Jul",
"Aug",
"Sept",
"Oct",
"Nov",
"Dec"
]
let endDate = new Date(projectDate.endDate)
let startDate = new Date(projectDate.startDate)
function getProjectDuration(endDate, startDate) {
endDate = new Date(projectDate.endDate)
startDate = new Date(projectDate.startDate)
const distance = endDate - startDate
const miliseconds = 1000
const secondInMinute = 60
const minuteInHour = 60
const secondInHour = secondInMinute * minuteInHour // 3600
const hourInDay = 23
const dayInMonth = 30
let dayDistance = distance / (miliseconds * secondInHour * hourInDay)
if (dayDistance >= 30) {
return `${Math.floor(dayDistance / dayInMonth)}` + ` Bulan`
} else {
return `${Math.floor(dayDistance)}` + ' Hari'
}
}
const projectDetailDate = {
edDate: endDate.getDate(),
edMonth: month[endDate.getMonth()],
edYear: endDate.getFullYear(),
sdDate: startDate.getDate(),
sdMonth: month[startDate.getMonth()],
sdYear: startDate.getFullYear()
}
const projectDuration = getProjectDuration()
const projectData = {
projectImage,
projectTitle,
projectContent,
projectDate,
projectDuration,
projectTech,
projectDetailDate
}
project.push(projectData)
res.redirect('/')
})

主数组：
let project = []
所有的 js 代码和主数组都放在一个文件中，如下所示：
let project = [] app.get() app.post()
在 /editproject 页面我使用：
let projectEdit = project.map(function(data) { return { ...data = req.body }})
操作数组并根据我在 req.body 编辑表单中输入的内容更新它，当我 console.log(projectEdit) 它显示更新的值但是当我使用 console.log(project) 它仍然没有改变， /addproject 中的值仍然相同，它仅在编辑表单中更新。
我的目标是使用编辑表单通过索引更新数组中的对象（所有博客内容值）。
卡了几个小时，我搜索并尝试了很多，但没有任何效果。
提前致谢。
您需要更改 URL 以包含项目 ID
然后通过合并两个对象简单地更新项目。
app.post('/editproject/:id', function(req, res) {
project[req.params.id] = {
...project[req.params.id],
...req.body
};
res.redirect('/')
})
您还需要将id发送给客户端
app.get('/editproject/:id', function(req, res) {
let data = req.params.id
let edit = project[data]
// pass the data as id property and render it so you can use it in the url
res.render('editproject', { id: data, title: 'Edit Project', editForm: edit })
})

主数组：
let project = []
所有的 js 代码和主数组都放在一个文件中，如下所示：
let project = [] app.get() app.post()
在 /editproject 页面我使用：
let projectEdit = project.map(function(data) { return { ...data = req.body }})
操作数组并根据我在 req.body 编辑表单中输入的内容更新它，当我 console.log(projectEdit) 它显示更新的值但是当我使用 console.log(project) 它仍然没有改变， /addproject 中的值仍然相同，它仅在编辑表单中更新。
我的目标是使用编辑表单通过索引更新数组中的对象（所有博客内容值）。
卡了几个小时，我搜索并尝试了很多，但没有任何效果。
提前致谢。
您需要更改 URL 以包含项目 ID 然后通过合并两个对象简单地更新项目。
app.post('/editproject/:id', function(req, res) {
project[req.params.id] = {
...project[req.params.id],
...req.body
};
res.redirect('/')
})
您还需要将id发送给客户端
app.get('/editproject/:id', function(req, res) {
let data = req.params.id
let edit = project[data]
// pass the data as id property and render it so you can use it in the url
res.render('editproject', { id: data, title: 'Edit Project', editForm: edit })
})
