ExtJS:Simple Form忽略formBind [英] ExtJS: Simple Form ignores formBind
问题描述
我有一个小问题让我疯狂了几天。我有一个表单面板:
Ext.define('EC.view.PasswordPanel',{
extends:' Ext.form.Panel',
别名:'widget.pwdpanel',
bodyPadding:15,
initComponent:function(){
this .initialConfig = {url:'/ password /'};
this.fieldDefaults = {
labelAlign:'right',
labelWidth:135,
msgTarget: 'side',
allowBlank:false,
inputType:'password'
};
//this.listeners = {
////规则破坏formBind
// validchange:function(comp,valid){
//this.down('button').setDisabled(!valid);
//}};
this.buttons = [{
text:'Change',
formBind:true,
scope:this,
handler:function(){
this.subm它({
success:function(form,action){
Ext.Msg.alert(
'Success',
'< p>密码更改已成功安排。 < / p>'+
EC.DELAY_NOTICE);
form.reset();
},
失败:function(form,action){
if('result'in action&&
'msg'in action.result){
Ext.Msg.alert('Error',action.result.msg);
}
}
});
}
}];
this.items = [{
xtype:'textfield',
name:'pw_old',
fieldLabel:'旧密码'
},{
xtype:'textfield',
name:'pw_new1',
id:'pw_new1',
fieldLabel:'新密码',
minLength:8,
maxLength:16
},{
xtype:'textfield',
name:'pw_new2',
fieldLabel:'确认新密码',
}];
this.callParent(arguments);
}
});
我在TabPanel内实例化了一个标签:
$ b $
项目:{xtype:'pwdpanel'},
},
现在,验证工作完全正常,但是在窗体无效时,更改按钮不会被禁用。要清楚:当我按下它时,它不会提交,但我觉得应该被禁用?
我在做某件事情错误?第二个选项卡中的另一个表单面板工作得很好。
我可以使用我注释掉的监听器来规避问题,但是我明白它应该可以正常工作。 / p>
PS随意指出任何愚蠢/不好的风格,我是ExtJS的新手。
这是extjs的明显错误,因为即使他们自己的示例也是一样的
然而,我发现了快速的解决方法 - 添加到 initComponent
行:
this.on('afterrender',function(me){
delete me.form._boundItems;
});
这里是小提琴。
更新
错误在4.0.7中修复。
I have a tiny problem that is driving me crazy for days. I have a form panel:
Ext.define('EC.view.PasswordPanel', {
extend: 'Ext.form.Panel',
alias: 'widget.pwdpanel',
bodyPadding: 15,
initComponent: function() {
this.initialConfig = {url:'/password/'};
this.fieldDefaults = {
labelAlign: 'right',
labelWidth: 135,
msgTarget: 'side',
allowBlank: false,
inputType: 'password'
};
//this.listeners = {
//// circumvent broken formBind
//validitychange: function(comp, valid) {
//this.down('button').setDisabled(!valid);
//}};
this.buttons = [{
text: 'Change',
formBind: true,
scope: this,
handler: function() {
this.submit({
success: function(form, action) {
Ext.Msg.alert(
'Success',
'<p>Password change has been scheduled successfully.</p>' +
EC.DELAY_NOTICE);
form.reset();
},
failure: function(form, action) {
if ('result' in action &&
'msg' in action.result) {
Ext.Msg.alert('Error', action.result.msg);
}
}
});
}
}];
this.items = [ {
xtype: 'textfield',
name: 'pw_old',
fieldLabel: 'Old password'
}, {
xtype: 'textfield',
name: 'pw_new1',
id: 'pw_new1',
fieldLabel: 'New password',
minLength: 8,
maxLength: 16
}, {
xtype: 'textfield',
name: 'pw_new2',
fieldLabel: 'Confirm new password',
} ];
this.callParent(arguments);
}
});
which I instantiate a tab from within a TabPanel:
{
title: 'Change Password',
items: { xtype: 'pwdpanel' },
},
Now, the validation works perfectly fine, but the "Change" button isn't disabled while the form isn't valid. To be clear: When I press it, it doesn't submit, yet I feel it should be disabled?
Am I doing something obvious wrong? Another form panel in a second tab works just fine.
I can circumvent the problem using the listener I commented out, but I understand that it should work w/o.
P.S. Feel free to point out any stupidities/bad style, I'm totally new to ExtJS.
It's clear bug of extjs because even their own example works the same.
However, I've found quick workaround - add to initComponent
lines:
this.on('afterrender', function(me) {
delete me.form._boundItems;
});
Here is fiddle.
UPDATE
The bug is fixed in 4.0.7.
