（extjs）获取表单中单选按钮的选定值。 没有返回值

Question

I've followed the basic procedures for obtaining the selected value of my radio button form.

        ....
        xtype: 'radiofield',
        name: 'timespan',
        id: 'timespan',
        value: 7,
        checked: true,
        fieldLabel: 'Time Span',
        boxLabel: '7 days'
    }, {
        xtype: 'radiofield',
        name: 'timespan',
        value: '30',
        fieldLabel: '',
        labelSeparator: '',
        hideEmptyLabel: false,
        boxLabel: '30 days'
    }, {
        xtype: 'radiofield',
        name: 'timespan',
        value: '60',
        fieldLabel: '',
        labelSeparator: '',
        hideEmptyLabel: false,
        boxLabel: '60 days'
    }, {
        xtype: 'radiofield',
        name: 'timespan',
        value: 'all',
        fieldLabel: '',
        labelSeparator: '',
        hideEmptyLabel: false,
        boxLabel: 'All' ....

I've used methods like:

Ext.getCmp('filter_form').getForm().getValues()['timespan']

But when I run this to the console, instead of getting the value of the selected button, I get the word on . What gives?! I've tried several different combos of getValues, getForm, etc, but I always end up with on or true or false . What's going on here?

Answer 1

try setting inputValue property of radio. Which is the value that should go into the generated input element's value attribute and should be used as the parameter value when submitting as part of a form.

{
        xtype          : 'radiofield',
        name           : 'timespan',
        inputValue     : '30',
        hideEmptyLabel : false,
        boxLabel       : '30 days'
}

then it can be accessed as

Ext.ComponentQuery.query('[name=timespan]')[0].getGroupValue();

refer docs getGroupValue

Answer 2

Figured it out! Turns out that my extjs sample code has an error!

I changed value to inputValue . Taken from the Sencha Docs, inputValue is:

The value that should go into the generated input element's value attribute and should be used as the parameter value when submitting as part of a form. Defaults to: 'on'

Aha!! Because I hadn't specified a "real" value, it defaulted to on .

Be careful when using the extjs examples/sample code!
