推荐答案

使用$ parent和bind关键字

luse the $parent and bind keywords

<a data-bind="click: $parent.functionName.bind($parent)" />

$ parent将指向持有modelList数组的对象，它将调用一个名为functionName的函数，bind将确保this关键字是正确的上下文.该函数将单击该项目作为参数

$parent will point to the object holding the array of modelList and it will call a function called functionName, bind will ensure that the this keyword is the correct context. The function will have the item clicked as the argument
