using javascript functions get_text() and set_text() gives an error

[Nick]

Hello,

I'm having a problem with the javascript functions set_text() and get_text() functions.
Below is a simple page to demonstrate. When I click the button I get an error saying " Object doesn't support this property or method"
I've already searched the forums but none of the existing topics helped me out.

Thanks in advance for any tips!
Regards,
Jasper

Hello Jasper,


Since JavaScript is case sensitive, you must be careful when calling the method and variables. From your code, I can see that you usedget_Text() instead of get_text().

Try the following code:

function Test() {
  var combo = $find('<%=RadComboBox1.ClientID%>');
  alert(combo.get_text());
}

*Sigh..*
Programming can sometimes be so easy...

Thanks Shinu :-)

Hello,

I am attempting something similat but cant get the code to work other than in an event of the ComboBox, see below:

var cmbType = $get('<%= uiRadCmbContentType.ClientID %>');
alert(cmbType.get_text());

This is running in a user control on a aspx page, using 2009 Q2 controls. I get the standard object does not support this property or method error if I use get_text() or get_value().

Any thoughts?

THanks,

Ken

I've just managed to use .value as opposed to .get_value().

Not sure if this is to do with the version of the control.

Thanks,

Hi Ken,

You should use $find method to access the client-side object of RadComboBox (not $get). $get returns its DOM element.
