小编gue*_*314的帖子

我在JavaScript中有一个'item'对象,该项可以有颜色,大小等设置.

我需要在数组中获得所有可能的组合.

所以我们假设我们有一个看起来像这样的项目:

var newItem = {
    name: 'new item',
    Settings: [
        {name: 'color', values: ['green', 'blue', 'red']},
        {name: 'size',  values: ['15', '18', '22']},
        {name: 'gender',values: ['male', 'female']}
    ]
};

我需要以某种方式得到这个:

[
    [{SettingName:'color',value:'green'},{SettingName:'size',value:'15'},{SettingName:'gender',value:'male'}],
    [{SettingName:'color',value:'blue'},{SettingName:'size',value:'15'},{SettingName:'gender',value:'male'}],
    [{SettingName:'color',value:'red'},{SettingName:'size',value:'15'},{SettingName:'gender',value:'male'}],
    [{SettingName:'color',value:'green'},{SettingName:'size',value:'18'},{SettingName:'gender',value:'male'}],
    [{SettingName:'color',value:'blue'},{SettingName:'size',value:'18'},{SettingName:'gender',value:'male'}],
    [{SettingName:'color',value:'red'},{SettingName:'size',value:'18'},{SettingName:'gender',value:'male'}],
    [{SettingName:'color',value:'green'},{SettingName:'size',value:'22'},{SettingName:'gender',value:'male'}],
    [{SettingName:'color',value:'blue'},{SettingName:'size',value:'22'},{SettingName:'gender',value:'male'}],
    [{SettingName:'color',value:'red'},{SettingName:'size',value:'22'},{SettingName:'gender',value:'male'}],
    [{SettingName:'color',value:'green'},{SettingName:'size',value:'15'},{SettingName:'gender',value:'female'}],
    [{SettingName:'color',value:'blue'},{SettingName:'size',value:'15'},{SettingName:'gender',value:'female'}],
    [{SettingName:'color',value:'red'},{SettingName:'size',value:'15'},{SettingName:'gender',value:'female'}],
    [{SettingName:'color',value:'green'},{SettingName:'size',value:'18'},{SettingName:'gender',value:'female'}],
    [{SettingName:'color',value:'blue'},{SettingName:'size',value:'18'},{SettingName:'gender',value:'female'}],
    [{SettingName:'color',value:'red'},{SettingName:'size',value:'18'},{SettingName:'gender',value:'female'}],
    [{SettingName:'color',value:'green'},{SettingName:'size',value:'22'},{SettingName:'gender',value:'female'}],
    [{SettingName:'color',value:'blue'},{SettingName:'size',value:'22'},{SettingName:'gender',value:'female'}],
    [{SettingName:'color',value:'red'},{SettingName:'size',value:'22'},{SettingName:'gender',value:'female'}]
]

• Web Speech API可以与Web Audio API结合使用吗？

• 如何从Speech Synthesis API访问音频结果？

• 将HTML5 SpeechSynthesisUtterance生成的语音记录到文件中

• 使用W3C Web Speech API生成音频文件

但似乎没有使用创建的变通方法window.speechSynthesis().虽然有一些解决方法使用epeak,meSpeak 如何在Chrome浏览器中创建文本或将文本转换为音频？或向外部服务器发出请求.

如何捕捉和记录的音频输出window.speechSynthesis.speak()调用和返回结果为Blob,ArrayBuffer,AudioBuffer或其他对象类型？

目前,Chromium和Firefox的Web Speech API规范的实现不支持在SSML设置为实例属性并传递给调用时解析语音合成标记语言(SSML); 看看浏览器的SSML解析实现 ; 5.2.3 SpeechSynthesisUtterance属性 ; 如何设置浏览器调用的命令选项？.textSpeechSyntheisUtterancewindow.speechSynthesis.speak()

该speech-dispatcher文档指出用户配置文件可用于设置特定客户端的参数

可以使用以下参数设置命令.对于配置和历史客户端,还有用于为某些其他连接和所有连接设置值的功能.它们在下面单独列出.

C API函数:int spd_set_data_mode(SPDConnection *connection, SPDDataMode mode)设置Speech Dispatcher数据模式.目前,支持纯文本和SSML.如果要在文本中使用索引标记或包含语音参数的更改,SSML特别有用.

mode是请求的数据模式:SPD_DATA_TEXT或 …

我正在开发一个 angular 4 应用程序。我有一个 base64 编码的图像。我用 node.js 将它保存在文件系统中。

 if (body.profilepic != "") {
            let base64Data = body.profilepic.split(';base64,').pop();

            fs.writeFile("out.png", base64Data, 'base64', function(err) {
                if (!err) {
                    console.log("saved file")
                }
            });
        }

问题是我无法检测到我正在保存的图像的文件类型。现在它只保存 png。

如何检测我收到的图像字符串的文件类型？

我得到的 base64 编码字符串是这样的：

需求:

将输入整数或十进制转换为数组,并将可能包含小数的整数数组转换为数字.

限制:

在过程中不要使用字符串方法或将输入或输出转换为字符串(在组成的每个版本的代码中都遵循自我限制).

上下文和用例

BigInt在某些浏览器中可用,但不是 BigDecimal.使用JavaScript编程语言可以实现从整数或十进制到数组和数组到整数或十进制的转换.在过程中,输入和输出不需要转换为字符串.

能够通过调整数组的第n个索引处的十进制或整数来调整整数或十进制的第n位,以尝试直接解决OEIS A217626,例如

~~(128.625*9*1.074)//1243
~~(128.625*9*1.144)//1324

其中可以通过引用数组的索引来操作小数部分,然后将数组转换回数字.

当前规范是WIP,并且可能被认为难以描述与输入的小数部分的处理相关,特别是在存在前导零的情况下.

var res = arr.filter(Number) // [1, 2, 4, 6, 7, 9, Array[1]]

var res = arr.filter(Array.isArray) // [Array[1]]

var res = arr.filter(String) // [1, 2, true, 4, Object, 6, 7, Object, 9, Array[1]]
