我希望你可以在我的例子中找到

  Ext.onReady（function（）{


 var newForm = Ext.create（'Ext.form.Panel'，{

 title：Form ，
 items：[
 {
 xtype：textfield，
 fieldLabel：Name
}，
 {
 xtype：' textareafield'，
名称：'message'，
 fieldLabel：'Message'

} 

]，
 renderTo：document.body 
}）; 

 var win = new Ext.Window 
（{
 title：Window，
 layout：'fit'，
 height：250，
宽度：300，
项目：[newForm]，
按钮：[
 {
文本：提交，
处理程序：function（）{
 var textFieldValue = newForm.items.items [0] .getValue（）; 
 var textAreaValue = newForm.items.items [1] .getValue（）; 
 if（textFieldValue！= || textAreaValue！=）{
 alert（你可以提交数据）; 
} 
 else {
 alert（你不能提交数据 ）; 
 } 
} 
} 
] 
}）。show（）; 

}）; 
 

I am using ExtJS 3.4.0

I have a form in "var new" variable that comes to Ext.Window().

I need to do code that checks between textfield and textarea is one of them empty or not.

I mean if textfield is empty and textarea is not then form data can be submitted vice versa.

This code must be placed to the code that starts like below:

newform
.getForm()
.submit(

I hope you can find in my example

Ext.onReady(function(){


var newForm=Ext.create('Ext.form.Panel',{

            title:"Form",
            items:[
                  {
                   xtype:"textfield",
                   fieldLabel:"Name"
                  },
                  {
                        xtype     : 'textareafield',
                        name      : 'message',
                        fieldLabel: 'Message'

                    }

                  ],
            renderTo:document.body
  });

              var win= new Ext.Window
                    ({
                     title:"Window",
                     layout:'fit',
                     height:250,
                     width:300,
                     items:[newForm],
                     buttons:[
                              { 
                               text:"Submit",
                               handler:function(){
                                 var textFieldValue=newForm.items.items[0].getValue();
                                 var textAreaValue=newForm.items.items[1].getValue();
                                 if(textFieldValue!=""||textAreaValue!=""){
                                   alert("you can submit the data");
                                   }
                                   else{
                                   alert("you can't submit the data");
                                   }
                                }
                              }
                             ]
                   }).show();

});
