在Blaze模板中访问对象的属性名称 [英] Access an object's property names in a Blaze template
问题描述
Template.profile.helpers({
info: {
名称:'Bob Dinkleberg',
年龄:45,
地点:'地球,银河'
}
});
我想将这些信息放在< ul>
。这里有一些伪代码:
< template name =profile>
< ul>
{{#each}}
< li> {{key}}:{{property}}< / li>
{{/每个}}
< / ul>
< / template>
如果这很琐碎,请原谅我,我是流星新手和Blaze,我一直无法在网上找到解决方案。

您想要使用 {{#with}}
。
<$ p $ lt; code>< template name =profile>
< ul>
{{with info}}
< li> {{Name }}< / li>
< li> {{年龄}}< / li>
< li> {{Location}}< / li& with}}
虽然你的帮手代码是正确的:
Template.profile.helpers({
info:{
名称:'Bob Dinkleberg',
年龄:45 ,
地点:'地球,银河'
}
});
我个人喜欢养成将helper的名称映射到返回值的函数的习惯。
Template.profile.helpers({
info:function(){
return {
名称:'Bob Dinkleberg',
年龄:45,
位置:'地球,银河'
};
}
});
编辑
< $ {
info:function(){
var obj = {
名称:'Bob Dinkleberg' ,
年龄:45,
位置:'Earth,Milky Way'
};
var arrayOfObjects = [];
//创建一个数组(key in obj){
arrayOfObjects.push({key:key,value:obj [key]});
};
console.log(这是对象数组:,arrayOfObjects);
return arrayOfObjects;
},
});
HTML:
{{#each info}}
{{value}}
{{/ each}}
Say I have a helper that looks like this:
Template.profile.helpers({
info: {
Name: 'Bob Dinkleberg',
Age: 45,
Location: 'Earth, Milky Way'
}
});
I want to put this info in a <ul>
. Here is some pseudo-code:
<template name="profile>
<ul>
{{#each}}
<li> {{key}}: {{property}} </li>
{{/each}}
</ul>
</template>
Forgive me if this is trivial, I am new to Meteor and Blaze, and I haven't been able to find a solution online.

You want to use {{#with}}
.
<template name="profile">
<ul>
{{#with info}}
<li>{{Name}}</li>
<li>{{Age}}</li>
<li>{{Location}}</li>
{{/with}}
</ul>
</template>
While your helper code is correct:
Template.profile.helpers({
info: {
Name: 'Bob Dinkleberg',
Age: 45,
Location: 'Earth, Milky Way'
}
});
I personally like to make a habit of mapping the name of the helper to a function that returns something.
Template.profile.helpers({
info: function(){
return {
Name: 'Bob Dinkleberg',
Age: 45,
Location: 'Earth, Milky Way'
};
}
});
EDIT
Template.content.helpers({
info: function(){
var obj = {
Name: 'Bob Dinkleberg',
Age: 45,
Location: 'Earth, Milky Way'
};
var arrayOfObjects = [];
// creating an array of objects
for (key in obj){
arrayOfObjects.push({key: key, value: obj[key]});
};
console.log("This is the array of objects: ", arrayOfObjects);
return arrayOfObjects;
},
});
HTML:
{{#each info}}
{{value}}
{{/each}}
