Assigning empty string

[aliasg]

When I use "document.StartNo" expr = "" in assign tag it generates following error. If I give empty space like following statement, it works fine. "document.StartNo" expr = " "

Any idea what is error? No script tag on the page.

Hi,

The reason you are seeing that IVR error is because <assign name="document.StartNo" expr = ""/> translates to:

document.StartNo = ;

in javascript, which is illegal javascript.

To assign an empty string, you should do the following:

Code: Select all

<assign name="document.StartNo" expr = "''"/>

which would translate to:

document.StartNo = '';

Hope this sample IVR code using the IVR tag, <assign>, helps.
