我有一个表单面板,它使用表格布局来显示表单。我需要添加功能来添加/删除一组组件。
添加按钮应在现有元素下方添加一行新组件。删除按钮应删除最后添加的行。
formpanel可以添加一个新字段,但它出现在按钮下方,表单的宽度不会增加(参见下面的屏幕截图)。我已尝试使用insert和add函数,但两者都有相同的效果。
有谁知道如何: 1)我可以在下一行添加一系列组件吗? 2)我如何删除下一行。
部分formPanel代码&按钮代码:
![SearchForm = Ext.extend(Ext.FormPanel, {
id: 'myForm'
,title: 'Search Form'
,frame:true
,waitMessage: 'Please wait.'
//,labelWidth:80
,initComponent: function() {
var config = {
items: [{
layout:{
type:'table',
columns:5
},
buttonAlign:'center',
defaults:{
//width:150,
//bodyStyle:'padding:100px'
style:'margin-left:20px;'
},
items:[//row 1
{
xtype: 'label',
name: 'dateLabel',
cls: 'f',
text: "Required:"
},
{
xtype: 'container',
layout: 'form',
items: {
xtype: 'datefield',
fieldLabel: "From Date",
value: yesterday,
width: 110,
id: 'date1'
}
}][1]
buttons: [{
text: 'Add More Criteria (max 10 items)',
id: "addBtn",
scope: this,
handler: function(){
alert('hi');
/*this.items.add({
xtype : 'textfield',
fieldLabel : 'Extra Field',
name : 'yourName',
id : 'yourName'
}); */
this.insert(4,{
xtype: 'textfield',
id: 'input20',
//hideLabel: true,
width: 180,
fieldLabel: 'hi'
});
this.doLayout();
}
}

动态表单字段生成似乎很明显,有很多示例和一些博客用于mootools等但在extjs世界中我找不到一个有效的例子(可能是因为大多数人使用强大的Extjs网格)。我不得不发明我自己为MedAlyser项目!并且即时与你分享。她可能有错误和/或不完整但我希望她有所帮助。
function addressCounter(incr) {
if (!this.no) {
this.no = 0;
} else {
this.no = this.no + 1;
};
};
var counter = new addressCounter();
console.log(counter.no);
//put below code inside your form items
{
xtype: 'button',
text: 'Add address ',
id: 'addaddress',
handler: function () {
counter.no = counter.no + 1;
console.log(counter.no);
Ext.getCmp('patientaddress').add([{
xtype: 'combo',
store: 'AddressType',
displayField: 'name',
valueField: 'name',
fieldLabel: 'Address Type',
id: 'addresstype' + counter.no,
name: "Patientaddress[addresstype][]",
value: 'Home'
}, {
fieldLabel: 'zip',
width: 160,
maxLength: 10,
enforceMaxLength: true,
maskRe: /[\d\-]/,
regex: /^\d{5}(\-\d{4})?$/,
regexText: 'Must be in the format xxxxx or xxxxx-xxxx',
name: "Patientaddress[zip][]",
id: 'zip' + counter.no
}, {
fieldLabel: 'Address 1',
name: "Patientaddress[address1][]",
id: 'address1' + counter.no
}, {
fieldLabel: 'Address 2',
name: "Patientaddress[address2][]",
id: 'address2' + counter.no
}, {
fieldLabel: 'City',
name: "Patientaddress[city][]",
id: 'city' + counter.no
}, {
fieldLabel: 'State',
name: "Patientaddress[state][]",
id: 'state' + counter.no
}, {
xtype: 'combo',
store: Ext.create('MA.store.Countries'),
displayField: 'name',
valueField: 'id',
forceSelection: true,
fieldLabel: 'Country',
typeAhead: true,
queryMode: 'local',
name: "Patientaddress[country][]",
id: 'country' + counter.no
} // eof
// countries;
,
Ext.getCmp('addaddress'), {
xtype: 'button',
text: 'Remove address',
id: 'removeaddress' + counter.no,
handler: function (
thisButton, eventObject) {
activeRemoveButtonId = thisButton.getId().split('removeaddress')[1];
console.log('activeRemoveButtonID:' + activeRemoveButtonId);
Ext.getCmp('patientaddress').remove('address1' + activeRemoveButtonId);
Ext.getCmp('patientaddress').remove('address2' + activeRemoveButtonId);
Ext.getCmp('patientaddress').remove('city' + activeRemoveButtonId);
Ext.getCmp('patientaddress').remove('state' + activeRemoveButtonId);
Ext.getCmp('patientaddress').remove('country' + activeRemoveButtonId);
Ext.getCmp('patientaddress').remove('removeaddress' + activeRemoveButtonId);
Ext.getCmp('patientaddress').remove('addresstype' + activeRemoveButtonId);
Ext.getCmp('patientaddress').remove('zip' + activeRemoveButtonId);
Ext.getCmp('patientaddress').doLayout();
}
}]);
Ext.getCmp('patientaddress').doLayout();
} // eof function
}, // eof Add button
删除字段更复杂,因为删除按钮需要确切地知道必须删除哪个字段。此代码会根据您的要求创建新字段并正确删除它们。欢迎提出任何建议。
