Captures the browser output until the end tag, and save it into a variable.

           STANDARDOUTPUTLEVEL = "html, text, compresswhitespace"> 
</MvCAPTURE>
  • Closed Tag

Sometimes we deal with functions that output directly to the screen. By capturing the output in a variable, it is possible to pass the results to another function or save the output to a file.

Attributes

  • VARIABLE: Required. Variable name or expression that results in a variable name where the captured output is stored.
  • STANDARDOUTPUTLEVEL: Optional keywords: html, text, compresswhitespace. Specifies what gets returned in VARIABLE. If omitted, output is returned un-altered.
    • html: Default. HTML is output to the browser.
    • text: Default. Text (non html) is output to the browser.
    • compresswhitespace: will cause Miva Script to eliminate extra whitespace in the output of Miva Script code. Whitespace is leading and trailing spaces, tabs, and new lines.

Syntax

Example:

<MvCAPTURE VARIABLE = "l.output_variable">
    text, expressions, etc.
</MvCAPTURE>

In this example we capture the html output of a function that creates a dropdown list of states.

Example:

<MvCAPTURE VARIABLE = "l.state_selbox">
    <MvCOMMENT> Outputs a select box to the browser. </MvCOMMENT>
    <MvEVAL EXPR="{ State_Select(g.ShipTo_State) }">
</MvCAPTURE>
