我的页面中有userdata render('page',{userdata: data})使用userdata。
{
usename: "jim",
latLng: {lat: 10, lng: -8},
address: {
line1: "10 Main Street"
line2: "London"
country: "Great Britan"
},
about: "I am jim"
}
是具有属性的对象：
page.ejs在我的<% console.log("My User data: " + userdata) %>
<% console.log("The latLng field: " + userdata.latLng) %>
文件中，我有以下两行代码作为测试。
My user data: {usename: 'jim',
latLng: {lat: 10, lng: -8},
address: {
line1: "10 Main Street"
line2: "London"
country: "Great Britan"
},
about: 'I am jim'}
第一个显示到控制台：
The latLng field: undefined
但第二行显示：
typeof userdata有谁知道发生了什么？是因为它们是数字而不是字符串？ latLng是保留变量名吗？我对于为什么会发生这种情况一无所知。
我尝试了什么：
将lat和lng保存为字符串。 （没效果）
进一步的信息：
object在呈现过程中返回typeof data。
object也会返回//Names that correspond to 5 values in table1 and 5 in tab
