使用jquery點擊添加按鈕添加瀏覽框實現struts多文件上傳。
例如：點擊添加，添加一個瀏覽框。
Jsp頁面代碼：
<%@page language="java" import="java.util.*"pageEncoding="utf-8"%>
<%
Stringpath = request.getContextPath();
StringbasePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
<!DOCTYPEHTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<meta http-equiv="Content-Type"content="text/html; charset=utf-8" />
<title>Untitled Document</title>
<scripttype="text/javascript" src="./js/jquery-1.7.1.js">
</script>
<scripttype="text/javascript">
$(function(){
var i = 2;
$("#add").click(function(){
$("#main").append(
'<div>上傳文件：<inputtype="file" name="upload"/></div>');
});
});
</script>
</head>
<body>
<div align="center">
<formaction="${pageContext.request.contextPath}/csdn/upFiles.action"
enctype="multipart/form-data"method="post">
<div id="main">
<div>
上傳文件：<input type="file"name="upload" />
</div>
</div>
<input type="button"id="add" name="button" value="添加"/>
<input type="submit" value="上傳"/>
</form>
</div>
</body>
</html>
UploadsAction代碼：
packagecn.csdn.hr.up.action;
importjava.io.File;
importjava.io.IOException;
importorg.apache.commons.io.FileUtils;
importorg.apache.struts2.ServletActionContext;
importcom.opensymphony.xwork2.ActionSupport;
publicclass UploadsAction extends ActionSupport {
// 規定
private File upload[];// 上傳文件
// 上傳文件的類型
private String uploadContentType[];
// 上傳文件的名稱
private String uploadFileName[];
public File[] getUpload() {
return upload;
}
public void setUpload(File[] upload) {
this.upload = upload;
}
public String[] getUploadContentType() {
return uploadContentType;
}
public void setUploadContentType(String[]uploadContentType) {
this.uploadContentType =uploadContentType;
}
public String[] getUploadFileName() {
return uploadFileName;
}
public void setUploadFileName(String[]uploadFileName) {
this.uploadFileName = uploadFileName;
}
public String uploads() {
String path =ServletActionContext.getServletContext().getRealPath(
"/ims");
File file = new File(path);
if (!file.exists()) {
file.mkdirs();
}
/**
* 以流的方式 讀取文件 寫入到指定文件中去mkdirs mkdir區別 FileUtils工具完成上傳
*/
try {
for(int i=0;i<upload.length;i++){
FileUtils.copyFile(upload[i], newFile(file, uploadFileName[i]));
}
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
System.out.println("上傳文件的名稱:" +getUploadFileName() + "------上傳文件的類型"
+ getUploadContentType());
return SUCCESS;
}
}
導入所需jar包：
