成功处理程序不会使用extjs进行文件上传 [英] Success handler not getting called in file upload using extjs
问题描述
给出js代码:
Ext.onReady(function ){
Ext.QuickTips.init();
var msg = function(title,msg){
Ext.Msg.show({
标题:title,
msg:msg,
minWidth:200,
modal:true,
图标:Ext.Msg.INFO,
按钮:Ext.Msg 。
};
};
var fp = new Ext.FormPanel({
renderTo:'fi-form',
fileUpload:
width:500,
frame:true,
title:'Upload XML Config File',
autoHeight:true,
bodyStyle:'padding:10px 10px 0 10px;',
labelWidth:50,
defaults:{
anchor:'95%',
allowBlank:false,
msgTarget:'side'
},
items:[{
xtype:'fileuploadfield',
i d:'form-file',
emptyText:'选择要上传的xml文件',
fieldLabel:'File',
name:'file',
buttonCfg:{
text:'',
iconCls:'upload-icon'
}
}],
按钮:[{
text:'Upload'
处理程序:function(){
if(fp.getForm()。isValid()){
fp.getForm()。submit({
url:'uploadXML.htm ',
waitMsg:'上传你的xml文件...',
success:function(fp,o){
msg('Success','Processed file''+ o.result服务器上的.file +');
}
});
}
if(!validateFileExtension(Ext.getDom('form-file')。value)){
Ext.MessageBox.alert('选择另一个文件',
'只有XML文件。
返回;
}
}
},{
文本:'重置',
处理程序:function(){
fp.getForm() ;
}
}]
});
函数validateFileExtension(fileName){
var exp = /^.*\.(xml|XML)$/;
return exp.test(fileName);
}
});
不知道我错过了什么。
提前感谢。 >
'uploadXML.htm'必须是PHP或类似的服务器端程序。这个PHP必须返回JSON字符串,如:{'success':true}或{'success':false}。
I have a J2EE web app with a form where I upload a file to a location on a server. During the upload a waitMsg is shown to the user which should disappear once the upload is completed with a msgBox indicating the same. The code for the success case is also provided in the js file. However the upload works fine, but the waitMsg continues even after the upload at the server has completed.
The js code is given:
Ext.onReady(function(){
Ext.QuickTips.init();
var msg = function(title, msg){
Ext.Msg.show({
title: title,
msg: msg,
minWidth: 200,
modal: true,
icon: Ext.Msg.INFO,
buttons: Ext.Msg.OK
});
};
var fp = new Ext.FormPanel({
renderTo: 'fi-form',
fileUpload: true,
width: 500,
frame: true,
title: 'Upload XML Config File ',
autoHeight: true,
bodyStyle: 'padding: 10px 10px 0 10px;',
labelWidth: 50,
defaults: {
anchor: '95%',
allowBlank: false,
msgTarget: 'side'
},
items: [{
xtype: 'fileuploadfield',
id: 'form-file',
emptyText: 'Select the xml File to upload',
fieldLabel: 'File',
name: 'file',
buttonCfg: {
text: '',
iconCls: 'upload-icon'
}
}],
buttons: [{
text: 'Upload',
handler: function(){
if(fp.getForm().isValid()){
fp.getForm().submit({
url: 'uploadXML.htm',
waitMsg: 'Uploading your xml file...',
success: function(fp, o){
msg('Success', 'Processed file "'+o.result.file+'" on the server');
}
});
}
if (!validateFileExtension(Ext.getDom('form-file').value)) {
Ext.MessageBox.alert('Select another file',
'Only XML file, please.');
return;
}
}
},{
text: 'Reset',
handler: function(){
fp.getForm().reset();
}
}]
});
function validateFileExtension(fileName) {
var exp = /^.*\.(xml|XML)$/;
return exp.test(fileName);
}
});
Not sure what I am missing.
Thanks in advance.
'uploadXML.htm' must be PHP or similar server side procedure. this PHP must return JSON string, like : {'success':true} or {'success':false}.
