ToScript 889

Usage

To use a ColdFusion variable in JavaScript or ActionScript, the ToScript function must be in a

cfoutput region and be surrounded by number signs (#). For example, the following code uses

the

ToScript function to convert a ColdFusion variable to a JavaScript variable:

var #toScript(thisString, "jsVar")#;

</cfoutput>

</script>

When ColdFusion runs this code, it sends the following to the client:

var jsVar = "hello world";

</script>

An HTML script tag must enclose the JavaScript code. The cfoutput tag does not need to be

inside the script block; it can also surround the block.

WDDX-style output generates JavaScript code that creates a WDDXRecordset object, where the

key of each record set entry is a column name, and the value of the recordlist entry is an array of

the corresponding query column entries, as follows:

WDDXQuery = new WddxRecordset();

col0 = new Array();

col0[0] = "John";

col0[1] = "John";

WDDXQuery["firstname"] = col0;

col0 = null;

col1 = new Array();

col1[0] = "Lund";

col1[1] = "Allen";

WDDXQuery["lastname"] = col1;

col1 = null;

To use WDDX-style output, you must first load the cf_webroot/CFIDE/scripts/wddx.js script,

which defines JavaScript WDDX objects, as in the following line:

For more information on WDDX in JavaScript, see Chapter 9, “WDDX JavaScript Objects,” on

page 1091.

ActionScript-style output generates code that creates an array of objects, where the array is

indexed by row number, and the objects consist of column name - column value pairs, as follows:

ActionScriptQuery = new Array();

ActionScriptQuery[0] = new Object();

ActionScriptQuery[0]['firstname'] = "John";

ActionScriptQuery[0]['lastname'] = "Lund";

ActionScriptQuery[1] = new Object();

ActionScriptQuery[1]['firstname'] = "John";

ActionScriptQuery[1]['lastname'] = "Allen";
