AngularJS - 在页面加载时将数据引导到服务中

时间:2021-10-06 14:59:40

In an angularjs app, I am attempting to use a custom service to hold the app's main data, "items". However, I would like to bootstrap the data into the service upon the initial page load, in order to avoid a separate ajax request to the server to get it. What would be cleanest way to go about doing this?

在angularjs应用程序中,我试图使用自定义服务来保存应用程序的主要数据“项目”。但是,我想在初始页面加载时将数据引导到服务中,以避免向服务器发出单独的ajax请求。这样做最干净的方法是什么?

Here is a snippet of my service for reference:

以下是我的服务片段供参考:

app.factory('items', function() {
    var itemsService = {},
        items = [];

    itemsService.list = function() {
        return items;
    };

    itemsService.add = function() {
        /* ... */
    };

    return itemsService;
});

And on the backend I am using node.js + expressjs + jade, so I would be injecting the data into the page using:

在后端我使用node.js + expressjs + jade,所以我将使用以下方法将数据注入页面:

!{JSON.stringify(items)}

Put your bootstrapped data from the server into a global JavaScript variable. Have your service assign items to that global variable (or copy the data into items).

将来自服务器的引导数据放入全局JavaScript变量中。让您的服务将项目分配给该全局变量(或将数据复制到项目中)。

How about something like this:

这样的事情怎么样:

app.run(['items', function (items) {
   items.load();
}])

This presumes your items service has a load function (or something like it) that does the actual Ajax work using either $http or $resource.

这假设您的项目服务具有加载功能(或类似的东西),使用$ http或$ resource执行实际的Ajax工作。
