添加所有列值的最佳方法是什么？
JSON
[
{
"id": "men",
"label": "men",
"value": 3,
"color": "#468df3"
},
{
"id": "women",
"label": "women",
"value": 5,
"color": "#ba72ff"
},
{
"id": "children",
"label": "children",
"value": 5,
"color": "#a1cfff"
}
]
我从服务器获取数据我想添加所有值并在控制台中显示它.例如,控制台中的const值= 3 + 5 + 5 = 13.
我正在对我的后端进行提取调用，这是调用。
\n\n const response = await fetch(apiUrl + \'/recipes\', {\r\n method: \'POST\',\r\n headers: {\r\n \'Content-Type\': \'application/json\',\r\n \'Authorization\': `Token token=${user.token}`\r\n },\r\n body: JSON.stringify({\r\n recipe: {\r\n recipeId: uri\r\n }\r\n })\r\n })然后这是我在后端发送呼叫的路线
\n\nrouter.post(\'/recipes\', requireToken, (req, res) => {\r\n req.body.recipe.owner = req.user.id\r\n Recipe.create(req.body.recipe)\r\n .then(recipe => {\r\n console.log(\'Recipe object saved is\', recipe)\r\n res.status(201).json({ recipe: recipe.toObject() })\r\n })\r\n .catch(err => handle(err, res))\r\n})当我这样做时，正确的对象会在发回之前记录。这是记录内容的示例
