ui-router:传入一个不在 url 中的参数? [英] ui-router: passing in a param that not in the url?

问题描述

我在传递一个不是 url 参数的参数时遇到问题.

I am having a problem passing in a param that's not a parameter in the url.

我基本上对点击事件有以下内容

I basically have the following on a click event

let stateParams = {
    id: event.info.id,
    info: event.info
};

this.$state.go('home.showinfo', stateParams);

我仔细检查了 stateParams 是否包含 id 和 info 对象.

I have double checked on the stateParams contains the id and also the info object.

然后我对状态进行了以下设置

I then have the following setup on the state

.state('home.showinfo', {
    url: 'info/info/:id',
    resolve: {
        info: function($stateParams){
            return $stateParams.info;
        }
    },
    params: {
        info: null
    }

在我的控制器中，我正在检查 $stateparams 的值，我看到了 id(URL 也包含 ID)，但 info 对象为空.它始终为空.我只想能够在控制器中访问它.this.info"也为空.

In my controller I am checking the value of $stateparams, and I see the id (also the URL contains the ID), but the info object is null. It's always null. I just want to be able to access it in the controller. Also "this.info" is also null.

我在 resole 中放置了一个断点并且 info 为空.

I put a breakpoint in the resole and info is null.

我尝试删除上面的 params:{} ，但仍然没有.

I have tried removing the params:{} above and still nothing.

知道我做错了什么吗?

推荐答案

有一个工作plunker

代码应该可以正常工作，请检查调用方两次.这些链接将执行预期的操作:

The code should be working, check twice the calling side. These links will do what is expected:

<a ui-sref="home.showinfo({id:1, info:'hi'})">
<a ui-sref="home.showinfo({id:2, info:'bye'})">

有一个状态如上:

.state('home.showinfo', {
    url: 'info/info/:id',
    templateUrl: 'showinfo.tpl.html',
    resolve: {
        info: function($stateParams){
            return $stateParams.info;
        }
    },
    params: {
        info: null
    }
})
