将CSV上传浏览按钮添加到Ext.Action [英] Adding CSV upload browse button to Ext.Action
问题描述
我想在GeoExt地图应用程式上建立CSV档案上传。
我需要将上传函数放在Ext.Action中,以便我可以将其添加到GeoExt面板的工具栏。我正尝试实施此示例。这是我的代码,
action = new Ext.Action({
text:Upload Excel,
control:Ext.create('Ext.form.Panel',{
title:'上传一个CSV文件',
width:400,
bodyPadding:10,
frame:true,
renderTo:Ext.getBody(),
items:[{
xtype:'filefield',
name:'csv',
fieldLabel: 'CSV Upload',
labelWidth:50,
msgTarget:'side',
allowBlank:false,
buttonText:'选择CSV文件'
}],
buttons:[{
text:'Upload',
handler:function(){
var form = this.up('form')
.getForm();
if(form.isValid()){
form.submit({
url:'file-upload.py',
waitMsg:'上传CSV File ...',
success:function(fp,o){
Ext.Msg.alert('Success','Your csv file''+ o.result.file +'has ');
}
});
}
}
}]
}),
map:map,
//按钮选项
tooltip:Upload CSV File ,
//检查项目选项
group:newTool
});
actions [upCSV] = action;
toolbarItems.push(new Ext.button.Button(action));
Firebug会给我这个错误,
TypeError:b [d.xtype ||我不是一个构造函数
我在Ext.Action中声明的函数不正确吗?
工具栏中 c>因为 Ext.Action
不是 Ext.Component
的类型。 Ext.Action
基本上是一种创建可以多次重用的抽象层的方法。这里你需要做以下事情: toolbarItems.push(new Ext.button.Button
从文档:
共享处理程序,配置选项和UI更新
跨越任何支持Action接口的组件(主要是
Ext.toolbar.Toolbar,Ext.button.Button和Ext.menu.Menu组件)
I am trying to create a CSV File upload on GeoExt Map App.
I need to place the upload function within the Ext.Action, so that I can add it to the toolbar of the GeoExt Panel. I am trying to implement this example. Here is my code,
action = new Ext.Action({
text: "Upload Excel",
control: Ext.create('Ext.form.Panel', {
title: 'Upload a CSV File',
width: 400,
bodyPadding: 10,
frame: true,
renderTo: Ext.getBody(),
items: [{
xtype: 'filefield',
name: 'csv',
fieldLabel: 'CSV Upload',
labelWidth: 50,
msgTarget: 'side',
allowBlank: false,
buttonText: 'Select CSV File'
}],
buttons: [{
text: 'Upload',
handler: function () {
var form = this.up('form')
.getForm();
if (form.isValid()) {
form.submit({
url: 'file-upload.py',
waitMsg: 'Uploading the CSV File...',
success: function (fp, o) {
Ext.Msg.alert('Success', 'Your csv file "' + o.result.file + '" has been uploaded.');
}
});
}
}
}]
}),
map: map,
// button options
tooltip: "Upload CSV File",
// check item options
group: "newTool"
});
actions["upCSV"] = action;
toolbarItems.push(new Ext.button.Button(action));
Firebug keeps giving me this error,
TypeError: b[d.xtype || e] is not a constructor
Am I declaring the function incorrectly within the Ext.Action?
解决方案 You can't directly push the action
into a toolbar
since an Ext.Action
is not a type of Ext.Component
. An Ext.Action
is basically a means of creating an abstraction layer which can be reused multiple times. Here you need to do the following:
toolbarItems.push(new Ext.button.Button(action));
From the documentation:
Actions let you share handlers, configuration options and UI updates
across any components that support the Action interface (primarily
Ext.toolbar.Toolbar, Ext.button.Button and Ext.menu.Menu components)
