问题描述
我从帮手中获得JSON
{
Name:abc,
年龄:24,
地址{
street:xyz street,
city:zyz city,
country:XY
$ / code $ / pre
我想用键和值打印地址 < template name =User>
{{#with user}}
姓名:{{姓名}}
年龄:{{年龄}}
{{#每个地址}}
{ key}}:{{value}} //这是我的问题
{{/ each}}
{{/ with}}
如何在模板中打印键和值?
{{#each}} 块帮助程序只接受游标和数组参数。
您可以重写Address helper,使其返回一个数组而不是一个对象。
模板.User.helpers({
地址:function(){
return _.map(this.Address,function(value,key){
return {
key:key,
value:value
};
});
}
});
您可能想将此实用程序函数定义为模板帮助程序:
JS
Template.registerHelper(objectToPairs,function(object){
return _.map(object,function(value,key){
return {
key:key,
value:value
};
});
});
HTML
< template name =User>
< ul>
{{#each objectToPairs Address}}
< li> {{key}} - {{value}}< / li>
{{/ each}}
< / ul>
< / template>
I have JSON from helper
{
"Name": "abc",
"Age": 24,
"Address" {
"street" : "xyz street",
"city" : "zyz city",
"country" : "XY"
}
}
I want to print the address with key and values
<template name="User">
{{#with user}}
Name : {{Name}}
Age : {{Age}}
{{#each Address}}
{{key}} : {{value}} //Here is my question
{{/each}}
{{/with}}
</template>
How to print key and values in a template?
解决方案 The {{#each}}
block helper only accepts cursors and arrays arguments.
You could override the Address helper to make it return an array instead of an object.
Template.User.helpers({
Address: function(){
return _.map(this.Address, function(value, key){
return {
key: key,
value: value
};
});
}
});
You might want to define this utility function as a template helper :
JS
Template.registerHelper("objectToPairs",function(object){
return _.map(object, function(value, key) {
return {
key: key,
value: value
};
});
});
HTML
<template name="User">
<ul>
{{#each objectToPairs Address}}
<li>{{key}} - {{value}}</li>
{{/each}}
</ul>
</template>
