Question

I am trying to replace a value with a passed value using javascript or coldfusion. The idea is we have a template which outputs values in the grid. But the values displayed need be dynamically determined by a query. So far I haven’t been able to come up with any good ideas.

Here is a sample of something I thought would of work (but does not). It may explain what I am trying to do:

<cfset StaticValue="DynamicValue">

<cfset DynamicValue="What I Want To Show">

<script type="text/javascript">
   document.getElementById("demo").innerHTML="<cfoutput>#StaticValue#</cfoutput>";
</script>

<cfoutput>#<span id="demo"></span>#</cfoutput>

Answer 1

To use an existing string/variable as a variable name, you need to use bracket notation.

In CF, if you haven’t explicitly scoped a variable, it is created in the Variables scope, so you can do:

<cfset StaticValue="DynamicValue">

<cfset DynamicValue="What I Want To Show">

<!--- outputs value of Variables.DynamicValue --->
<cfoutput>#Variables[StaticValue]#</cfoutupt>

(This works will all scopes/structs/queries/etc)

NOTE: If the variable is to be output inside of a JavaScript string, you need to wrap it in JsStringFormat(...) to ensure the appropriate characters are escaped.
