jQuery的AJAX +的responseText +字符编码 [英] jQuery ajax + responseText + Character encoding
问题描述
我执行一个Ajax请求的JavaScript和使用jQuery库的PHP脚本。
这是我的命令，该命令执行AJAX请求：
I perform an AJAX request to a PHP script in JavaScript and by using the jQuery library.
Here is my command which performs the AJAX request :
$.ajax({
async: "false",
cache: "false",
data: {login: strLogin, password: strPassword},
datatype: "text",
error: connexionAjaxError,
success: connexionAjaxSuccess,
type: "POST",
url: "./Connexion"
});
联接是一个URL重定向到我的PHP脚本。
connexionAjaxError是不可避免一旦接收到HTTP响应执行的JavaScript功能。
原因：我的PHP脚本结果为纯文本/页，HTTP状态code等于500
这是我的PHP脚本的最相关的部分：
".Connexion" is a URL redirection to my PHP script.
connexionAjaxError is a JavaScript function inevitably executed as soon as the HTTP response is received.
The reason : My PHP script results to a text/plain page with HTTP status code equal to 500.
Here is the most relevant part of my PHP script :
header("HTTP/1.0 500 Internal Server Error;
Content-type: text/plain;
charset=ISO-8859-1");
echo "été";
下面是connexionAjaxError回调函数的签名：
Here is the signature of the connexionAjaxError callback function :
function connexionAjaxError(jqXHR, textStatus, errorThrown)
我的PHP结果字符串ETE。
我的PHP内部编码为ISO-8859-1这样的结果字符串连接十六进制的codeD [E9 74 E9。
My PHP results to the string "été".
My PHP internal encoding is ISO-8859-1 so the result string is encoded [e9 74 e9] in hexadecimal notation.
但jqXHR.responseText在connexionAjaxError回调函数包含1个字符的字符串。
我已经使用了JavaScript的String对象的字符$ C $猫的方法来获得UNI code（UTF-8？）code表示的字符。
该角色是连接在十进制形式相当于codeD 65535 [FF FF]以十六进制表示。
But jqXHR.responseText in the connexionAjaxError callback function contains a 1-character string.
I have used the charCodeAt method of the JavaScript String object to get the unicode (UTF-8 ?) code for the character.
The character is encoded 65535 in decimal notation equivalent to [ff ff] in hexadecimal notation.
我不明白为什么jqXHR.responseText不包含3个字符的字符串端到端。
我不是在JavaScript方面的专家，但我想jqXHR.responseText只能包含一个字符串连接codeD的UTF-8。
因此，在jqXHR.responseText字符串ETE将连接以十六进制格式codeD [c3a9 74 c3a9。
我检索UTF-8 code从以下网站上的字符e： HTTP：/ /www.utf8-chartable.de/
I do not understand why jqXHR.responseText does not contain the 3-character string "été".
I am not an expert in JavaScript but I suppose jqXHR.responseText can only contains a string encoded in UTF-8.
So the string "été" in jqXHR.responseText would be encoded [c3a9 74 c3a9] in hexadecimal notation.
I have retrieve the UTF-8 code for the character "é" from the following web site : http://www.utf8-chartable.de/
推荐答案
我做了很多发展的西班牙语和我注意到一些东西，可以帮助你，因为我已经通过这个已经走了：
I make a lot of development in Spanish and I've noticed a few things that might help you, since I've gone through this already:
在头功能的字符集应该是UTF-8。
The charset in the header function should be UTF-8.
另外，文件本身（PHP脚本）必须保存在UTF-8，你可以很容易地做到这一点，如果你编辑与记事本++的文件，并选择编码为UTF-8无BOM。
Also, the FILE itself (the PHP script) must be saved in UTF-8, you can easily achieve this if you edit the file with Notepad++ and select the encoding to be UTF-8 without BOM.
也是一样的JavaScript和HTML文件，他们都应该是连接codeD使用UTF-8无BOM，而不是ANSI。
Same goes for your javascript and HTML files, they should all be encoded with UTF-8 without BOM rather than ANSI.
让我知道！
