Check a radio button using ExtJS

javascriptextjsradio-button

提问by David

I may be missing something, but how do I programmatically check a radiobutton using ExtJS (v 3)?

我可能遗漏了一些东西,但是如何使用 ExtJS (v 3) 以编程方式检查单选按钮?

The following doesn't seem to always work

以下似乎并不总是有效

var radio = Ext.get("myradiobutton");

var radio = Ext.get("myradiobutton");

radio.set("checked,"");

radio.set("检查,"");

The radio is sometimes checked, sometimes not...

有时检查收音机,有时不检查...

radio.is(":checked") sometimes return true, sometimes false

radio.is(":checked") 有时返回真,有时返回假

Thanks

谢谢

I'd suggested using this function: http://docs.sencha.com/ext-js/3-4/#!/api/Ext.form.Radio-method-setValue

我建议使用这个功能:http: //docs.sencha.com/ext-js/3-4/#!/api/Ext.form.Radio-method-setValue

var radio = Ext.get("myradiobutton");
radio.setValue(true);

Why not just use the DOM?

为什么不直接使用 DOM?

Ext.getDom('myradio').checked = true;
