extjs - ExtJS get value of hidden form field

Question

First off, thanks for your patience I'm pretty new to Ext. All I'm trying to do is get the value of a hidden form field on an HTML page and store its value a variable inside an ext script. Here's what I'm working with: HTML PAGE:

<form name="myForm">
<input type="hidden" id="accountID" name="divAccountID" value="463">
</form>

Ext Page:

var myAccountID = Ext.ComponentQuery.query('panel[name=myForm] #accountID');

Answer 1

这是最合适的：

var hidden = Ext.getCmp('accountID');
var hiddenValue = hidden.getValue();

Answer 2

    var win = Ext.widget('nameofviev');  

//The above line will find the view in which we want to find the hidden fields 

    win.down('hidden#row_id').setValue(index);

//The above line set the value of hidden field that's `id` is `row_id`.
//If we remove the `#row_id` it find first hidden field and set value of that

// 或者

var hidden = Ext.getCmp('accountID');
var hiddenValue = hidden.getValue();

Answer 3

你可以得到这样的值：

var v = Ext.get('accountID').dom.value;
