问题描述
所有我想要做的是当我单击我的表单上的重置按钮复位所有字段。而且我已经尝试了一切,但似乎并不奏效。这是有按钮的类:
App.views.HomeIndex = Ext.extend(Ext.form.FormPanel ,{
pre>
floating:true,
scroll:'vertical',
itemId:'jobSearch',
centered:true,
modal:true,
hideOnMaskTap:false,
items:[{
xtype:'textfield',
itemId:'keywords',
label:'Keywords',
labelAlign:'top ',
labelWidth:'100%',
name:'keywords'
},{
xtype:'textfield',
label:'Job Title'
itemId:'jtitle',
labelAlign:'top',
labelWidth:'100%',
name:'jtitle'
},{
.... // more xtypes here
,
dockedItems:[{
xtype:'toolbar',
itemId:'toolbar',
dock:'bottom',
height:'36',
items: [
{xtype:'button',text:'Reset',itemId:'resetBtn',
},
{xtype:'spacer'},
{xtype:按钮',文字:'提交',itemId:'submitBtn',ui:'action',
}
]
}]
在我的App.js中,我有代码来处理重置方法:
//这是我想到的一种方式。但显然这不行。我已经尝试过谷歌搜索,但找不到解决方案。this.homeView.query('#resetBtn')[0] .setHandler(function(){
var form = this.el.up('。x-panel');
//form.down('。x-input-text [name = keywords]')。setValue('');
form.query('#jobSearch')。getComponent('keywords')。reset();
});
});
Ext.reg('HomeIndex',App.views.HomeIndex);
解决方案尝试这个。这是一个更多的ExtJS喜欢。
var form = Ext.ComponentQuery.query('#jobSearch .form')[0] ;
form.reset();
All I want to do is when I click the reset button on my form it resets all fields. And I have tried everything but it does not seem to work. Here is the class that has the button in it:
App.views.HomeIndex = Ext.extend(Ext.form.FormPanel,{ floating: true, scroll: 'vertical', itemId: 'jobSearch', centered: true, modal: true, hideOnMaskTap: false, items: [{ xtype: 'textfield', itemId: 'keywords', label: 'Keywords', labelAlign: 'top', labelWidth: '100%', name: 'keywords' },{ xtype: 'textfield', label: 'Job Title', itemId: 'jtitle', labelAlign: 'top', labelWidth: '100%', name: 'jtitle' },{ .... //more xtypes here , dockedItems: [{ xtype: 'toolbar', itemId: 'toolbar', dock: 'bottom', height: '36', items: [ { xtype: 'button', text: 'Reset',itemId: 'resetBtn', }, { xtype: 'spacer'}, { xtype: 'button', text: 'Submit',itemId:'submitBtn',ui: 'action', } ] }]
In my App.js I have the code to handle the reset method: //this is one way I thought of doing it. But obviously it does not work. I have tried googling all over but couldnt find a solution.
this.homeView.query('#resetBtn')[0].setHandler(function(){ var form = this.el.up('.x-panel'); //form.down('.x-input-text[name=keywords]').setValue(' '); form.query('#jobSearch').getComponent('keywords').reset(); }); }); Ext.reg('HomeIndex', App.views.HomeIndex);
解决方案Try this. It's a bit more ExtJS like.
var form = Ext.ComponentQuery.query('#jobSearch .form')[0]; form.reset();
