Lodop、C-Lodop页面找不到报404错误解决

2016-12-23 13:17 260 查看

在使用 Lodop、C-Lodop打印控件时，使用火狐浏览器不报错，换成IE浏览器时报404错误（找不到控件的下载位置):

以前的配置如下：

1.spring-servlet.xml中配置（找到打印控件的位置）： <mvc:resources location="/WEB-INF/print/" mapping="/print/**"/>

下面是项目部分截图：

2.LodopFuncs.js的代码：

var CreatedOKLodop7766=null;

//====判断是否需要安装CLodop云打印服务器:====

function needCLodop(){

try{
var ua=navigator.userAgent;
if (ua.match(/Windows\sPhone/i) !=null) return true;
if (ua.match(/iPhone|iPod/i) != null) return true;
if (ua.match(/Android/i) != null) return true;
if (ua.match(/Edge\D?\d+/i) != null) return true;
if (ua.match(/QQBrowser/i) != null) return false;
var verTrident=ua.match(/Trident\D?\d+/i);
var verIE=ua.match(/MSIE\D?\d+/i);
var verOPR=ua.match(/OPR\D?\d+/i);
var verFF=ua.match(/Firefox\D?\d+/i);
var x64=ua.match(/x64/i);
if ((verTrident==null)&&(verIE==null)&&(x64!==null))
return true; else
if ( verFF !== null) {
verFF = verFF[0].match(/\d+/);
if ( verFF[0] >= 42 ) return true;
} else
if ( verOPR !== null) {
verOPR = verOPR[0].match(/\d+/);
if ( verOPR[0] >= 32 ) return true;
} else
if ((verTrident==null)&&(verIE==null)) {
var verChrome=ua.match(/Chrome\D?\d+/i);
if ( verChrome !== null ) {
verChrome = verChrome[0].match(/\d+/);
if (verChrome[0]>=42) return true;
};
};

return false;

} catch(err) {return true;};

};

报错如下：

修改LodopFuncs.js的代码后不在报错（代码如下）：
