有运营同学反映,后台编辑的一个中文显示名称,前台乱码了,于是乎~~
先看代码是否get请求没转码:
$.ajax({
type: 'POST',
url: '/admin/updatedisplayname}',
data: {displayName:displayName},
success: function(res){
alert(1);
},
error: function() {
alert(2);
},
dataType: 'json'
})奇怪~
问了下,对方用的是谷歌,检查他的浏览器编码有没特殊设置过,没有,一切正常。
纳闷,回来在谷歌测试下,晕死,果然重现,乱码了,哈哈,那就好办,查~
看看请求头信息啥的,发现使用$.ajax请求的时候有一个值有问题
chrome:contentType: 'application/x-www-form-urlencoded'
ff:contentType: 'application/x-www-form-urlencoded; charset=UTF-8',
难道是这个在作祟,如果乎~
$.ajax({
type: 'POST',
url: '/admin/updatedisplayname}',
data: {displayName:displayName},
contentType: 'application/x-www-form-urlencoded; charset=UTF-8',
success: function(res){
alert(1);
},
error: function() {
alert(2);
},
dataType: 'json'
})
莫不是有啥玄机,查看jquery手册
(默认: "application/x-www-form-urlencoded") 发送信息至服务器时内容编码类型。默认值适合大多数情况。如果你明确地传递了一个content-type给 $.ajax() 那么他必定会发送给服务器(即使没有数据要发送)
为毛我在不传入这个值的时候,火狐会加上 charset=UTF-8呢?
看看jquery源码:
ajaxSettings: {
url: location.href,
global: true,
type: "GET",
contentType: "application/x-www-form-urlencoded",
processData: true,
async: true,
/*
timeout: 0,
data: null,
username: null,
password: null,
traditional: false,
*/
// Create the request object; Microsoft failed to properly
// implement the XMLHttpRequest in IE7 (can't request local files),
// so we use the ActiveXObject when it is available
// This function can be overriden by calling jQuery.ajaxSetup
xhr: window.XMLHttpRequest && (window.location.protocol !== "file:" || !window.ActiveXObject) ?
function() {
return new window.XMLHttpRequest();
} :
function() {
try {
return new window.ActiveXObject("Microsoft.XMLHTTP");
} catch(e) {}
},
accepts: {
xml: "application/xml, text/xml",
html: "text/html",
script: "text/javascript, application/javascript",
json: "application/json, text/javascript",
text: "text/plain",
_default: "*/*"
}
},
contentType: 'application/x-www-form-urlencoded; charset=UTF-8',
不过,又有问题,有同学没有加,但是测试是ok的,谷歌不乱码,各种不淡定啊。。。。
再查~
首先想到检查jquery版本,果然,这哥们是用jquery1.7.2,而我用的是1.4.2,查看1.7.2的源码:
ajaxSettings: {
url: ajaxLocation,
isLocal: rlocalProtocol.test( ajaxLocParts[ 1 ] ),
global: true,
type: "GET",
contentType: "application/x-www-form-urlencoded; charset=UTF-8",
processData: true,
async: true,
/*
timeout: 0,
data: null,
dataType: null,
username: null,
password: null,
cache: null,
traditional: false,
headers: {},
*/
accepts: {
xml: "application/xml, text/xml",
html: "text/ht
