引起的原因：有get方法进行查询分页，而URL中包含"%"，本来是个警告，以为没什么关系。但把每个页面做完后，发现个大问题，哭死。。。就是传中文的时候有乱码,当然，这个问题是由get传递机制造成的，与这个警告没关系^_^

 

总结：只要URL中出现%，日志里都会记载这个错误。在百度或者Google中查询‘%’发现他们都替换成%25

如下：

 var content12=document.getElementById("content").value;
    var phone12=document.getElementById("phone").value;
    content12=content12.replace(/\%/g,'%25');//str=str.replace('%','%25');只能替换第一个%
    var url = "phonebookSelectnum.action?content12="+content12+"&phone12="+phone12;
