Detailed jquery uploadify upload file _javascript tips

Online search for a day, everyone said uploadify the only drawback is not to support the Chinese button, cups before, I looked at the next Uploadify API, just found a few parameters have not been mentioned, this is the key to solve this problem. (The habit of looking at the API in the future is firmly developed)
Uploadify There is a parameter is ButtonText this no matter how you do not support Chinese, because the plug-in in JS with a transcoding method to the value of this parameter to the code, decoding the place in that SWF file, see Code, so this road is not.
Another parameter, the Internet is rarely mentioned, is buttonimg (button picture), then you can use a picture to replace the plugin with the black Flash browse button, as long as your own picture is Chinese, this does not solve the Chinese button problem? If you only add this one, you will find your button picture below there is a white area, in fact, that Flash left, white area indicates the mouse available range, this range can be adjusted with Width,height. There is also a parameter wmode its default value is opaque, change it to transparent on the line, that is, the white area of transparency. Then use the method just said, the button click Range set to be as big as your picture is completely OK.

Uploadify usage is not said, online article a lot, and other jquery plug-in usage, is a few file placement path.
The following attached uploadify part of the parameters of the introduction, to see all of the API file to see, generally in the download of the package.

Uploadify also brought a lot of parameters and useful methods and callback functions, are in the API, although the whole English, but it is easy to understand, here is not said.
Here is the code I used to refer to:

Copy Code code as follows:

<script type= "Text/javascript" >
$ (document). Ready (function () {
$ ("#uploadify"). Uploadify ({
' Uploader ': ' images/uploadify.swf ',
' Script ': ' <%=request.getcontextpath ()%>/content/importschedulecommitaction.do ',
' cancelimg ': ' Images/cancel.png ',
' Folder ': '/',
' Queueid ': ' Filequeue ',
' Filedataname ': ' Uploadify ',
' Filedesc ': ' Support format: XLS. ',
' Fileext ': ' *.xls ',
' Auto ': false,
' Multi ': true,
' Height ': 20,
' Width ': 50,
' Simuploadlimit ': 3,
' ButtonText ': ' Fdsfdsf ... ',
' buttonimg ': ' Images/browse.jpg ',
' Hidebutton ': true,
' Rollover ': true,
' Wmode ': ' Transparent ',
Oncomplete:function (event, Queueid,fileobj, response, data)
{
$ (' <li></li> '). Appendto ('. Files '). Text (response);
},
Onerror:function (Event,queueid, Fileobj)
{
Alert ("File:" + fileobj.name + "upload failed");
}
Oncancel:function (Event,queueid, Fileobj)
// {
Alert ("Cancel file:" +fileobj.name);
// }
});
<script type= "Text/javascript" >
$ (document). Ready (function () {
$ ("#uploadify"). Uploadify ({
' Uploader ': ' images/uploadify.swf ',
' Script ': ' <%=request.getcontextpath ()%>/content/importschedulecommitaction.do ',
' cancelimg ': ' Images/cancel.png ',
' Folder ': '/',
' Queueid ': ' Filequeue ',
' Filedataname ': ' Uploadify ',
' Filedesc ': ' Support format: XLS. ',
' Fileext ': ' *.xls ',
' Auto ': false,
' Multi ': true,
' Height ': 20,
' Width ': 50,
' Simuploadlimit ': 3,
' ButtonText ': ' Fdsfdsf ... ',
' buttonimg ': ' Images/browse.jpg ',
' Hidebutton ': true,
' Rollover ': true,
' Wmode ': ' Transparent ',
Oncomplete:function (event, Queueid,fileobj, response, data)
{
$ (' <li></li> '). Appendto ('. Files '). Text (response);
}, www.th7.cn
Onerror:function (Event,queueid, Fileobj)
{
Alert ("File:" + fileobj.name + "upload failed");
}
Oncancel:function (Event,queueid, Fileobj)
// {
Alert ("Cancel file:" + fileobj.name);
// }
});

Note that my script property value is a request path, I found that after I set up multiple files (such as 3), not every request to upload 3 files, but still execute 3 requests, upload a file one at a time. This is no way, Uplodify has so many callback functions, if you handle multiple, the callback function parameters do not know what to take, because these parameters are not arrays.
In other words, no matter how many files you set up at the same time, it will be one to request and upload, just on the surface feel like there are multiple threads at the same time processing the upload request, just the appearance. And if you set the simuploadlimit too large will often make mistakes, I set to 5 when there are often one or two files failed to upload.
