首先需要引入上传控件
<script type="text/javascript" src="<%=basePath%>/js/ext/examples/ux/fileuploadfield/FileUploadField.js" charset="utf-8"></script>
弹出上传框对应extjs代码
var uploadForm=new Ext.FormPanel({
id:'uploadForm',
width:520,
frame:true,
fileUpload: true,
autoHeight:true,
bodyStyle:'10px 10px 0px 10px',
labelWidth:50,
enctype: 'multipart/form-data',
defaults:{
anchor: '95%',
allowBlank: false
},
items:[
{
xtype:'fileuploadfield',
emptyText: '请选择上传文件...',
fieldLabel: '文件：',
id:'uploadFile',
name: 'upload',
allowBlank: false,
blankText: '文件名称不能为空.',
buttonCfg: {
text: '选择...'// 上传文件时的本地查找按钮
}
}
],
buttons: [{
text: '上传',
handler: function(){
if(uploadForm.getForm().isValid()){
uploadForm.getForm().submit({
url:basePath+ '/documentManage/upload_upload.action',
method:'POST',
waitTitle: '请稍后',
waitMsg: '正在上传文档文件 ...',
success: function(fp, action){
Ext.MessageBox.alert('信息', action.result.msg);
Ext.getCmp("uploadFile").reset(); // 指定文件字段的id清空其内容
addwin.hide();
grid.store.load({params:{start : 0,limit : combo.value}});
},
failure: function(fp, action){
Ext.MessageBox.alert('警告', action.result.msg);
addwin.hide();
}
});
}
}
},{
text: '重置',
handler: function(){
uploadForm.getForm().reset();
}
}]
});
addwin = new Ext.Window({
title : '上传新文档',
closable : true,
width : 520,
autoHeight: true,
border : false,
plain : true,
modal : true,
layout : 'fit',
bodyStyle : 'padding:5px;',
maximizable : false,// 禁止最大化
closeAction : 'hide',
closable : true,// 是否有关闭
collapsible : true,// 可折叠
iconCls : 'bind',
items : [uploadForm]
