[web2py] JS: very small but very useful

[Val K]

Very small py-function that wraps any js-content in anonymous js-function

def JS_fun(*args_lst):
    def _inner(body):
        return "(function(%s){ %s ;})" % (','.join(args_lst), body)
    return _inner


>>> JS_fun( 'a', 'b' )( 'console.log(a,b)' )
'(function(a,b){ console.log(a, b) ;})'


>>> args= ['a', 'b']
>>> JS_fun(*args)('console.log(%s)' % ','.join(args))
'(function(a,b){ console.log(a, b) ;})'

>>> JS_call = lambda f: lambda *args: f + '(%s)' % ','.join([str(a) for a in 
args])
>>> JS_call( JS_fun('a', 'b')('console.log(a,b)') )('"text"', 123 )
'(function(a,b){ console.log(a,b) ;})("text", 123)'
