Loop through JSON in EJS

Question

I have codes in EJS below    lt script gt      var row   lt  -JSON stringify data   gt      console log row    lt  script gt   lt   for var i 0  i lt JSON stringify data  length  i       gt      lt tr gt        lt td gt          lt    JSON stringify data  i  id  gt        lt  td gt      lt  tr gt   lt       gt    output of row is correct  an array of 3 objects  each with properties id  name etc   I can manipulate the row to popuate the table in JS  However  I am wonderring whether there is a way to allow it be done in the above manner   When I run the code above  JSON stringify data  length is not 3  but rather the length of the whole string     Another questions is when I try to add    lt   alert  t       or  lt   window alert  t        it gives me  not defined  error     Helps appreciated   Regards Hammer

JSON stringify data  length return string length not Object length  you can use Object keys    lt   for var i 0  i  lt  Object keys data  length   i       gt    https   stackoverflow com a 14379528 3224296

JSON stringify returns a String  So  for example   var data           id  1  name   bob           id  2  name   john           id  3  name   jake         JSON stringify data    will return the equivalent of        id   1   name     bob       id   2   name     john       id   3   name     jake        as a String value   So when you have    lt   for var i 0  i lt JSON stringify data  length  i       gt    what that ends up looking like is    lt   for var i 0  i lt      id   1   name     bob       id   2   name     john       id   3   name     jake      length  i       gt    which is probably not what you want  What you probably do want is something like this    lt table gt   lt   for var i 0  i  lt  data length  i        gt      lt tr gt        lt td gt  lt    data i  id   gt  lt  td gt        lt td gt  lt    data i  name   gt  lt  td gt      lt  tr gt   lt       gt   lt  table gt    This will output the following table  using the example data from above     lt table gt     lt tr gt       lt td gt 1 lt  td gt       lt td gt bob lt  td gt     lt  tr gt     lt tr gt       lt td gt 2 lt  td gt       lt td gt john lt  td gt     lt  tr gt     lt tr gt       lt td gt 3 lt  td gt       lt td gt jake lt  td gt     lt  tr gt   lt  table gt
