[CLOSED] Override getValue() javascript function from numberField

[Pablo_Azevedo]

Is there any way to override getValue() javascript function from numberField?

It does this

    getValue : function(){
        return this.fixPrecision(this.parseValue(Ext.form.NumberField.superclass.getValue.call(this)));
    }

i'm making a custom control inheriting from numberfield and i need to call another function before returning.

Hi,

You might want to look into using the .createInterceptorfunction, see

http://dev.sencha.com/deploy/dev/doc...ateInterceptor

This will allow you to insert custom logic before the function is called, or after will createSequence

Hope this helps.

That's not really what i want...
I found out, browsing the documentation, that i can use Ext.extend to extend the javascript class, so i could do like:

Ext.form.MyNumberField = Ext.extend(Ext.form.NumberField, {
getValue: function() {
    return 1111;//test value, just to see if it works
}
});

but it's been really hard to figure out how can i associate this extended javascript class to my server class,i mean, when i access my class in javascript i's still Ext.form.NumberField, not Ext.form.MyNumberField.

If you are using markup and just want to override the .getValue function, you can use the following.

Example

<ext:NumberField ID="NumberField1" runat="server" GetValue="#(return this.getRawValue(); )" />

The #() is a "function token" and automatically wraps the inner login in a function(){} template.

Hope this helps.

You can also override the .getValue function by setting a CustomConfig item.

Example

<ext:NumberField ID="NumberField1" runat="server">
    <CustomConfig>
        <ext:ConfigItem Name="GetValue" Value="#(return this.getRawValue(); )" />
    </CustomConfig>
</ext:NumberField>
