把手/胡须 - 是否有内置的方式来循环对象的属性？ [英] Handlebars/Mustache - Is there a built in way to loop through the properties of an object?

问题描述

正如问题的标题所说，是否有一种循环对象属性的小胡子/句柄方式？

p>

  var o = {
 bob：'肯定'，
 roger：'未知'，
驴子：'什么屁股'
} 
  

然后我可以做些什么在模板引擎中相当于

  for（var prop in o）
 {
 //用say说明，在模板中设置一个变量并赋值属性值
} 
  

p>支持此功能已添加 到Handlebars.js，因此不再需要外部帮助。

如何使用它

对于数组：

  {{＃each myArray}} 
索引：{{ index}} Value = {{this}} 
 {{/ each}} 
  

对象：

  {{＃each myObject}} 
键：{{@key}} Value = {{this }} 
 {{/ each}} 
  

请注意，只有传递 hasOwnProperty 测试将被枚举。

As the title of question says, is there a mustache/handlebars way of looping through an object properties?

So with

var o = {
  bob : 'For sure',
  roger: 'Unknown',
  donkey: 'What an ass'
}

Can I then do something in the template engine that would be equivalent to

for(var prop in o)
{
    // with say, prop a variable in the template and value the property value
}

?

解决方案

Built-in support since Handlebars 1.0rc1

Support for this functionality has been added to Handlebars.js, so there is no more need for external helpers.

How to use it

For arrays:

{{#each myArray}}
    Index: {{@index}} Value = {{this}}
{{/each}}

For objects:

{{#each myObject}}
    Key: {{@key}} Value = {{this}}
{{/each}}

Note that only properties passing the hasOwnProperty test will be enumerated.
