如何从handlebarsjs

访问此json对象

    [ {
    "id" : 9,
    "name" : "Name1",
    "address" : "address1",
    "city" : "city1",
    "state" : "KS",
    "zip" : "11111",
    "country" : "USA",
    "fax" : "111111",
    "phone" : "1111111",
    "website" : "",
    "account" : "11111",
    "contacts" : []
}, {
    "id" : 12,
    "name" : "Name2",
    "address" : "address2",
    "city" : "city2",
    "state" : "NJ",
    "zip" : "11111",
    "country" : "USA",
    "fax" : "",
    "phone" : "1111",
    "website" : "",
    "account" : "11111",
    "contacts" : [ {
        "firstName" : "name",
        "lastName" : "lastname",
        "title" : "rep",
        "phone" : "3333",
        "email" : "33333"
    } ]
} ]

我已尝试使用{{name}}来访问名称，但这不起作用，那么我如何访问名称属性以及联系人下的嵌套firstName属性？

谢谢

Answer 1

首先需要索引数组以获取名称。类似的东西：

{{listObj[0].name}}

{{listObj[0].contacts.firstName}}

Answer 2

将javascript变量名称分配给JSON对象。

   var jsonstring = [ {
        "id" : 9,
        "name" : "Name1",
        "address" : "address1",
        "city" : "city1",
        "state" : "KS",
        "zip" : "11111",
        "country" : "USA",
        "fax" : "111111",
        "phone" : "1111111",
        "website" : "",
        "account" : "11111",
        "contacts" : []
    }]

然后你可以做 jsongstring [0] .name

您可以使用for循环遍历JSON并打印出您需要的信息

for ( var x = 0; x < jsonString.length; x++){
alert(jsonString[x].name);
alert(jsonString[x].contacts.firstName);
}

希望这有帮助

你很幸运：在Handlebars文档页面上非常清楚地解释了你的问题：

http://handlebarsjs.com/

只需向下滚动到“Handlebars Paths”部分，您就会看到它正确地说明了您正在寻找的内容（“Handlebars还支持嵌套路径，因此可以查找嵌套在当前上下文下的属性。 ..“）
