The front-end code:
The function uploadFiles () {
Var accessoryID=document. GetElementById (' accessoryID). The value;
Var param="msgID='& amp; AccessoryID="+ accessoryID;
Var fileData=https://bbs.csdn.net/topics/document.getElementById (' uploadFile.) files [0].
Var formData=https://bbs.csdn.net/topics/new formData ();
FormData. Enctype="multipart/form - the data";
FormData. Append (' uploadFile fileData);
The console. The log (formData. Get (' uploadFile '));
$. Ajax ({
Url: "& lt; % request. The getContextPath (); % & gt;/uploadgongGaoAccessory struts?" + param,//transport address
Type: "post",
Data: formData,//transport data
ProcessData: false,
ContentType: false,
Cache: false,
//success callback function
Success: the function (result) {

},
//callback function failure

//errorObj returned an error encapsulation of js object
//the error object to print to the browser console
The console. The log (errorObj);
//give a friendly reminder
Alert (" service busy,,, ");
}
});
}
