如何将变量传递给"data-target ="角度2 [英] How to pass variable to "data-target=" angular 2

问题描述

我正在使用angular 2打字稿，我想创建一个切换折叠列表. 这很简单，只有一个ID和data-target，但我在列表中循环浏览，所以我有动态ID名称.我想在我的data-target中传递一个变量，以便获取ID的动态名称.像这样的东西:

I'm working with angular 2 typescript and i want to create a toggle collapse list. This is simple with single id and data-target but i loop throught a list so i have dynamic id names. I want to pass a variable in my data-target so i can reach the dynamic names of the id's. something like this:

<a data-toggle="collapse" data-target="#{{theme.themeId}}>collapseHere </a> 但这给了我一个语法错误.

<a data-toggle="collapse" data-target="#{{theme.themeId}}>collapseHere </a> but this gives me a syntax error.

是否可以使用data-target传递变量?

Is it possibly to pass variables with a data-target?

推荐答案

您可以使用属性绑定.像这样的东西:

You could used attribute binding. Something like that:

[attr.data-target]="'#' + theme.themeId"
