Dear Avian Liao and JMeter Users:
Here is a list of things I check when a __javaScript function is not working.
Number 3 is probably the solution to Avian's problem.
1. The function name of __javaScript must start with two underlines. If it
does not, JMeter will not execute the function. All JMeter function names start
with two underlines, except for _StringFromFile, which starts with one
underline.
Right: ${__javaScript( ... )}
Wrong: ${javaScript( ... )}
2. If a function parameter contains a comma character, you must put the
escape character (backslash) before the comma. That causes JMeter to use the
comma as data rather than as a delimiter between parameters.
Right: ${__javaScript('str'.length,Comma\,InData)}
Wrong: ${__javaScript('str'.length,Comma,InData)}
3. To reference a variable in a function parameter, enclose the variable
name in single quotes.
Right: ${__javaScript('${MyString}'.length,MyStringLength)}
Wrong: ${__javaScript(${MyString}.length,MyStringLength)}
4. You can write an entire small JavaScript program in a __javaScript
function. For example, to get the current date in MM/DD/YYYY format, use the
code below. This example shows that you can declare variables and separate
lines with semicolons in the JavaScript code.
${__javaScript(var d = new Date(); var date = d.getDate(); $DATE =
(d.getMonth() + 1) + "/" + (date < 10 ? "0"+date : date) + "/" +
d.getFullYear();,DATE)}
Sincerely yours,
Kyle

Subject: question of ${_javaScript} function
Hi, All,
Anyone has experience passing variable between Jmtere variable and javascript
variable?
In my case, I have variable that was extracted by Regex, and I called it
"findMe", in function, I try to use javascript to see if I can reuse this
variable or not, so I did like
${__javaScript(${findMe}+123,showJava)}
After all this, I use Java Request to see how is the variable doing between
Jmeter and javascript, and it turns out nothing. Any ideal?
Al
