This new feature allows scripting-savvy publishers to write JavaScript inside their Content View in "view source" mode to create dynamic, adaptive text. This is very similar to Java Server Pages (JSP).

For example, this allows you to repeat a section of your document for different subsets of the data.

Scroll down for an example IOK file.

Requires 2.7 b96 or later. You must use "View Source" mode (the "<>" button in the Content View toolbar).

Existing syntax for dynamic content - {{ }}

The existing dynamic content syntax is as follows. You might not use this, but if you have inserted dynamic content using the "f" button in the Content View, this is what happens in "view source" mode:

<p><b>Total:</b> {{ SUBSET_SUM("Coupon") }}</p>

This example inserts the dynamic result of the sum of the "Coupon" field according to whatever data results after applying your filters.

New syntax for scripting - <# #> and <#= #>

<#
  if (x==5) {
    y = 3;
  } else {
    y = 2;
  }
  out.println("Write some text into the document, programmatically");
  var array = subset_uniquesList("Category");
  for (var i in array) {
    #>
    <b>Some text and HTML with <#=array[i]#> (inserted values)</b>
    <#
  }
#>

This example demonstrates some JavaScript then uses a loop over unique values (after applying filters) in a field to repeat a section containing both static content and inserted script expressions.

See the attached file for a larger example including comments.

Functions available in script blocks

formula("IF(RAND<0.5, true, false)")
Dynamically evaluates an arbitrary formula using normal Excel-like formula syntax (not script)

recordCount() or recordCount(subset)
See http://www.visokio.com/kb/functions-guide#RECORDCOUNT

subset("Field name", "Field value") or subset("Field name", "Field value", "Operator")
See http://www.visokio.com/kb/functions-guide#SUBSET

subset_sum("Field name") or subset_sum("Field name", subset)
See http://www.visokio.com/kb/functions-guide#SUBSET_SUM
Note that all SUBSET_? functions are supported in JavaScript. The SUBSET_UNIQUESLIST function is slightly different in that subset_uniquesList() returns a JavaScript array rather than a single String containing a comma-separated list.

textvalue(value) or textvalue(value, pattern)
See http://www.visokio.com/kb/functions-guide#TEXTVALUE

More to come.

Example IOK file

Open the attached file in 2.7 b96 or later. This shows a table whose rows come and go as you filter. Try filtering by the Category field. Also try dragging the date sliders to see the numbers update and the rows disappear.

Expand the toolbars (or choose Toolbars > View toolbars), then click the "<>" icon to view source. The source is well-commented and shows different ways of working with scripting.
