IE5迁移到IE11过程中遇到的一些问题
document.getElementById("idName")
IE11中严格区分idName的大小写,IE5不区分大小写,如果你在适配过程中遇到浏览器控制台报null错误, 就应该检查报错行是否idName大小写错误
获取frame的写法变化
IE5写法: document.frames("frameName")
IE11写法:document.frames["frameName"]
使用xhr(XMLHttpRequest)时, url不会自动将特殊字符转义,而是在特殊字符处截断, 需手动转义, 测试代码如下
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>test xhr</title>
</head>
<body>
<p>点击按钮执行 <em>test()</em> 函数.</p>
<button onclick="test()">点这里</button>
<script>
function test() {
var xhr;
if (window.ActiveXObject) {
alert("正在使用旧版本的Internet Explorer（IE5和IE6）")
xhr = new ActiveXObject("Microsoft.XMLHTTP");
} else {
xhr = new XMLHttpRequest();
}
var url = "http://localhost:8080/awesome/clientIp?param1=#test#";
// 在ie5中发现: 实际执行的url已被转义为:http://localhost:8080/awesome/clientIp?param1=%23test%23
// 在ie11和chrome中发现: 实际执行的url已被截断为:http://localhost:8080/awesome/clientIp?param1=
xhr.open(‘GET‘, url, false);
xhr.send(null);
}
</script>
</body>
</html>
IE11中微软弃用了zh_CN语言，而采用 zh_hans_CN，造成前台页面不能正常国际化, 后端可增加国际化过滤器解决此问题
后端测试接口 代码
// curl -v localhost:8080/awesome/locale
// ie打开:http://localhost:8080/awesome/locale ,请求头:Accept-Language: zh-Hans-CN, zh-Hans; q=0.5 ,后端打印 zh_CN_#Hans
// chrome打开: http://localhost:8080/awesome/locale ,请求头: Accept-Language: zh-CN,zh;q=0.9 ,后端打印 zh_CN
@GetMapping("/locale")
public Locale locale(HttpServletRequest httpServletRequest) {
Locale locale = httpServletRequest.getLocale();
logger.info("/locale , locale is:{}", locale);
return locale;
}
国际化过滤器代码
package com.varyuan.awesome.filter;
import org.springframework.stereotype.Component;
import javax.servlet.*;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletRequestWrapper;
import java.io.IOException;
import java.util.Locale;
// 国际化过滤器
// 适配情况:ie11中弃用了zh_CN请求头，而采用zh-Hans-CN
@Component
public class I18nFilter implements Filter {
private final String zh = Locale.CHINA.getLanguage();
private final String CN = Locale.CHINA.getCountry();
@Override
public void doFilter(ServletRequest servletRequest, ServletResponse servletResponse, FilterChain filterChain) throws IOException, ServletException {
HttpServletRequestWrapper zhCnWrapper = new HttpServletRequestWrapper((HttpServletRequest) servletRequest) {
@Override
public Locale getLocale() {
Locale loc = super.getLocale();
String language = loc.getLanguage();
String country = loc.getCountry();
if ((zh.equals(language) && CN.equals(country))) {
return Locale.CHINA;
} else {
return loc;
}
}
};
filterChain.doFilter(zhCnWrapper, servletResponse);
}
}
