Usage
Within the cfquery and cfmail tags, this function does not output to the current page; it writes to the current SQL statement or mail text. Do not use WriteOutput within cfquery and cfmail. Although you can call this function anywhere within a page, it is most useful inside a cfscript block.
Example 1
<cfscript>
// encodeFor=url
writeoutput("encoding for url: ");
writeoutput("lorem ipsum _*&%^$%&@","url");
</cfscript>Output
encoding for url: lorem+ipsum+_*%26%25%5E%24%25%26%40
Example 2
<cfscript>
// encodeFor=html
writeoutput("encoding for html: ");
writeoutput("lorem ipsum _*&%^$%&@","html");
</cfscript>Output
encoding for html: lorem ipsum _*&%^$%&@
Example 3
<cfscript>
// encodeFor=css
writeoutput("encoding for css: ");
writeoutput("lorem ipsum _*&%^$%&@","css");
</cfscript>Output
encoding for css: lorem\20 ipsum\20 \5f \2a \26 \25 \5e \24 \25 \26 \40
