在流星空间键模板中按索引返回数组项 [英] Return array item by index in a meteor spacebars template
问题描述
我想访问流星模板中数组的第一项,我正在使用这种语法:
I want to access the first item of an array inside a meteor template, I'm using this syntax :
<p>{{array[0]}}</p>
然而它似乎不起作用。我不想使用 {{#each}}
迭代值,只需从数组中选择第一个。
However it doesn't seem like it's working. I don't want to iterate through values using {{#each}}
, just pick the first one from the array.
推荐答案
这只是一个语法问题,正确的如下:
This is just a problem of syntax, the correct one is the following :
<p>{{array.[0]}}</p>
注意数组属性之间的。
点括号(数组索引)表示法?
Notice the .
dot between the array property and the brackets (array indexing) notation ?
