How to extract value from javascript?

Question

I have below javascript response

<script language='javascript'>var p=parent;
p._isDuplicateDocName=false;
p.reloadDocStructureAfterSaveAs("xyz");

I am trying to extract 'reloadDocStructureAfterSaveAs' value from above using Regular expression extractor

Expression: reloadDocStructureAfterSaveAs("(.+?)")

but value is not getting extracted into reference variable. Please advice

Answer 1

You must escape outer parenthesis with \ as ( & ) has special meaning i.e., for grouping.

Use the regex as follows:

reloadDocStructureAfterSaveAs\("(.+?)"\)

Use Debug Sampler & View Results Tree in combination while debugging the script.
