javascript - How can I get rid of the error "Unsupported format of the sourcemap" while loading jquery-migrate.min.js? -
i getting following error message in visual studio 2013 debug window:
'iexplore.exe' (script): loaded http://localhost:4453/scripts/lib/jquery-migrate.min.js
unsupported format of sourcemap
module load messages turned on (debug window context menu). know there should jquery-migrate.min.js.map file, unfortunately not distributed jquery team.
now tried use empty file, , tried use jquery.min.map file (simply renaming copy jquery-migrate.min.js.map), both don't work.
i have looked on jquery site, provide map file jquery not jquery-migrate: download map file jquery 2.1.4
since file not available download (or did @ wrong location), how can create such file scratch? seems json formatted file.
note: there information available @ stackoverflow site map files (see bootstrap-3-1-1-what-is-the-map-extension-file-used-for). , give idea syntax of sourcemaps, can read this: source map revision 3 proposal
unfortunately, trying mimick sourcemap using information proposal did not help, error message still shown.
what tried creating file jquery-migrate.min.js.map in same path minified file jquery-migrate.min.js:
{"version":3, "file":"jquery-migrate.min.js", "sources":["jquery-migrate.js"], "names":["$"],"mappings":";eaaizkc"}
(no idea how mapping code being calculated)
unfortunately, did not help.
then thought suppress error message changing file jquery-migrate.min.js in following way:
i.e., commented out line
//@ sourcemappingurl=dist/jquery-migrate.min.map
so file looks (the code below truncated easier reading, note last line /*---disabled: //@ sourcemappingurl=dist/jquery-migrate.min.map ---*/):
/*! jquery migrate v1.1.1 | (c) 2005, 2013 jquery foundation, inc. , other contributors | jquery.org/license */ jquery.migratemute===void 0&&(jquery.migratemute=!0),function(e,t,n){function r(n){o[n]||(o[n]=!0,e.migratewarning....................
/---disabled: //@ sourcemappingurl=dist/jquery-migrate.min.map ---/
but error message still occurred. astro gave me right hint (see answer). thank you!
note (to reviewers changed message above): error message thrown visual studio , link local link points iisexpress. don't change error message.
