从JavaScript插件访问config.xml首选项 [英] Access config.xml preferences from JavaScript plugins

问题描述

在我的项目 config.xml 中添加了自定义偏好设置：

In my project's config.xml I added a custom preference:

<preference name="FooBar" value="Baz" />

plugin.js 我想访问此类功能的值。

Then, in my custom plugin's JavaScript inside <plugin>/www/plugin.js I want to access the value of such feature.

Cordova是否将这些值暴露给JavaScript端？我在相关文档中找不到任何信息。

Does Cordova exposes those values to the JavaScript side? I couldn't find any information in the documentation about it.

尝试：

var argscheck = require('cordova/argscheck');
argscheck.getValue('FooBar'); // Returns just FooBar

推荐答案

iOS，WP7，WP8，Windows8和可能的Ubuntu

You could use following code on iOS, WP7, WP8, Windows8, and probably Ubuntu

function readConfig() {
    var xhr = new XMLHttpRequest();
    xhr.addEventListener("load", function () {
        var parser = new DOMParser();
        var doc = parser.parseFromString(xhr.responseText, "application/xml");
        alert("Description : " + 
              doc.getElementsByTagName("description").item(0).textContent);
    });
    xhr.open("get", "../config.xml", true);
    xhr.send();
}

您必须从../ config.xml到../../ android_res / xml / config.xml

此外没有官方的阅读配置插件：
