Best way to reference datasource values in a javascript extension?

[joseph_brown]

I have an extension setup to control the opinionlab invitation survey. There is a section in the extension to list out the customvars I want to capture and I need to reference elements that are in my datasources. What would be the best way to reference datasource values in the below snippet.

customVariables: {

s_vi: s_vi

}

Hi Joe, I believe you are looking for this:

customVariables: {

s_vi: b["js_page.s_vi"]

}

For future reference:

Normal data sources

b.variable

Javascript Page Variable

b["js_page.variable"]

Meta Tag

b["meta.variable"]

Querystring Parameter

b["qp.variable"]

Cookie Value

b["cp.variable"]

// Assuming the s_vi is the SiteCatalyst visitor cookie.. (use the "cp." for cookies)

customVariables: {

s_vi: b["cp.s_vi"]

}
