A couple of weeks ago, I ranted about the lack of proper Unicode support in Javascript. Granted, Javascript supports Unicode strings, but if you want to parse such strings to numbers (e.g., the user enters a phone number using Chinese numerals), you will have to handle this yourself. So...
由于JavaScript只能处理UCS-2编码,造成所有字符在这门语言中都是2个字节,如果是4个字节的字符,会当作两个双字节的字符处理。JavaScript的字符函数都受到这一点的影响,无法返回正确结果。 还是以字符 为例,它的UTF-16编码是4个字节的0xD834 DF06。问题就来了,4个字节的编码不属于UCS-2,JavaScript不认识,只会把它...
Endianness is the sequential order in which bytes are arranged into larger numerical values when stored in memory or when transmitted over digital links. 简单来说,字节序就是字节之间的顺序,当传输或者存储时,如果数字超过1个字节,需要指定字节间的顺序。字节序用英语说就是 byte order mark,简称BOM。 字...

Otherwise, if thetag has the attributecharset, then that encoding is used. Even though the attributetypeholds a valid media type, that type must not have the parametercharset(like in the aforementionedContent-Typeheader). That ensures that the values ofcharsetandtypedon’t clash. Otherwise,...
The numerical values that make up a character encoding are known as "code points" and collectively comprise a "code space", a "code page", or a "character map". 字符编码是将数字分配给图形字符的过程,特别是人类语言的书写字符,使它们能够使用计算机进行存储、传输和转换。组成字符编码的数值称为“...
您可以使用ajax获取值并将其作为选项插入,如下所示: (请记住,这里对值的获取是模拟的,它只返回数组) async function getValuesWithAjax() { return ["test1", "test2", "test3"];}$(function() { getValuesWithAjax().then(values => { values.forEach(value => { $(".selectpicker").append($(""...
