如何解决如何在JavaScript中获取.js脚本的源代码？
|$.ajax({url: \'http://gmaps-samples-v3.googlecode.com/svn-history/r16/trunk/xmlparsing/util.js\',dataType: \'script text text\',crossdomain:\'true\',success: function(msg,status,obj){console.log(msg);console.log(status);console.log(obj)},mimetype: \'text/plain\',cache:false});
解决方法
但是从所有的权利来看，我是否应该随心所欲地在jQuery中解释它？
浏览器中的安全机制阻止您执行此操作，因为它可以使您从其他网站窃取用户的私人信息。如果您要向与脚本所在的域相同的域发出请求，则该请求将起作用。否则，您将无法使用JavaScript发出请求，而需要从服务器发出请求。
, 请注意，我将jQuery 1.6.1与jQuery Mobile 1.0a4.1和PhoneGap一起使用。
您的dataType应该为\“ text \”，而不是\“ script text text \”：
$.ajax({url: \'http://gmaps-samples-v3.googlecode.com/svn-history/r16/trunk/xmlparsing/util.js\',dataType: \'text\',crossdomain:\'true\',success: function(msg,status,obj){console.log(msg);console.log(status);console.log(obj)},mimetype: \'text/plain\',cache:false});
