这样做我已经

我也试过$ state.href,但我找不到方法 传递值(我不能使用href,因为给我404)
那是什么方式?
答案 0 :(得分:3)
此处的例外情况来自 GUID 实际上是string
。因此我们无法将其作为数字处理,即没有撇号:'
所以,因为你的电流看起来像这样:
// the one of the $scope.signals
current {
_id: '016ab73979797971605013efc42942e8',
...
}
我们必须通过类似的方式更改参数,而不是:
// GUID is not a number
var href = $interpolate('blog_details({id:{{_id}},slug:{{slug}}})')(current);
我们必须使用: '{{_id}}'
// GUID is a string here
var href = $interpolate('blog_details({id:\'{{_id}}\',slug:{{slug}}})')(current);
