Object doesn't support this property or method

[dlebowski]

Hi.  Why do I get this message when doing this in IE:

 

document.getElementById('yourmessage').setProperty('value', decodeURIComponent(raw.data.yourmessage));

<input type='hidden' id="yourmessage">

First off, do you understand the error message?  If not, the error message means you have a reference to an object, call it O, and you are using a property P or method M that the object does not have.

 

In other words, you are attempting:

alert( O.P ); // use property P of object O, if P is not there you will receive this error

alert( O.M() ); // call method M of object O, if M is not there you will receive this error

 

You have a few places in your code where this might be occurring.

 

document.getElementById() is pretty standard, so that's probably not it.

 

I'm not familiar with setProperty() on DOM methods though.  Are you sure the object returned by document.getElementById('yourmessage') has a set property method?

 

Next you have an object called raw.  Are you sure that raw has a data property?  Are you sure that raw.data is an object?  Are you sure that raw.data.yourmessage is a property?  Can raw.data.yourmessage be converted to a string?

Yes, for the most part.

 

Are you sure that raw has a data property?

 

yes

 

Are you sure that raw.data is an object?

 

yes

 

Are you sure that raw.data.yourmessage is a property?

 

yes

 

Can raw.data.yourmessage be converted to a string?

 

Yes.  It is a string.

Perhaps you're looking to use setAttribute (or .value directly if you want to be old-school)?
