Answer 1

看一下你的form 中是否加了 enctype="multipart/form-data" 

Answer 2

<form action="...." method="post" enctype="multipart/form-data"

Answer 3

看不到你的页面具体内容，但是你报的错说你提交的类型不是multipart/form-data or multipart/mixed，应该是application/x-www-form-urlencoded改过了看看，这个在AJAX中，post传参方式的时候用过<form action="...." method="post" enctype="application/x-www-form-urlencoded
"

Answer 4

原来是我在js中没写跳转到哪个页面，报的这个错误，添加了document.sys_sendForm.action="../mobilelibrary/gcrukuadd.jsp";就可以了

Answer 5

if(document.sys_sendForm.action!="#"){
document.sys_sendForm.action="#";
}
你的这段代码，不知道有什么意义！问题可能也是由他造成的那，你相当于把一个document.sys_sendForm.action="#";在提交，
