json嵌套数组错误

Question

hey before i start with the main question i should state that the .json file is an external file in the same folder with .html files.I do not know if it helps but i am new to json.
My questions are 1) why jsfiddle throws throws errors at "papadopoulos_antonis": [{
"papadopoulos_stauros":=[{ "maria_anagnostou":= [{ 2) is it right to do <link src=.../> to read json file?

Thanks

 //this is in a json external file.the file is in the same folder with other html files users = [ "papadopoulos_antonis": [{ fname: 'Παπαδόπουλος Αντώνης', field1: 'Συντήρηση Αυτοκινήτου', field2: 'Ορειβατικός εξοπλισμός', field3: 'Μάθημα Καράτε', field4: '' }], "papadopoulos_stauros":[{ fname: 'Παπαδόπουλος Σταύρος', field1: 'Αναψυκτικά', field2: 'Αλκοολούχα ποτά', field3: 'Εξοδα καυσίμων', field4: '' }], "maria_anagnostou": [{ fname: 'Αναγνώστου Μαρία', field1: 'Διαφήμιση επιχείρησης', field2: 'Τεχνικός επιχείρησης', field3: 'Μηχανικός επιχείρησης', feild4: '' }] ] function jsonObjs(select) { var = JSONobject = JSON.parse(users); alert(users.papadopoulos_antonis[fname]); if (select == 1) { alert(users.papadopoulos_antonis[fname]); } else if (select == 2) { alert(users.papadopoulos_stauros[fname]); } else if (select == 3) { } } 

 <link src="formMembers.json" type="text/javascript"/> <select id="selectCategory" onchange="jsonObjs(this)"> <option>Επιλογή...</option> <option>Παπαδόπουλος Αντώνης</option> <option>Παπαδόπουλος Σταύρος</option> <option>Αναγνώστου Μαρία</option> </select>

JSON.parse an invalid JSON will not work.

users = [ is an array and an array should look like:

users = ["val", "val", "val"]

instead you have:

users = [prop:"val", prop:"val", prop:"val"]

which should instead be an Object:

users = {prop:"val", prop:"val", prop:"val"} // Plain Object (not valid JSON)

Fix your . >>> , typo.
For a valid JSON use double-quotes:

{
    "papadopoulos_antonis": {
        "fname": "ΠαπαδόπουλοςΑντώνης",
        "field1": "ΣυντήρησηΑυτοκινήτου",
        "field2": "Ορειβατικόςεξοπλισμός",
        "field3": "ΜάθημαΚαράτε",
        "field4": ""
    },
    "papadopoulos_stauros": {
        "fname": "ΠαπαδόπουλοςΣταύρος",
        "field1": "Αναψυκτικά",
        "field2": "Αλκοολούχαποτά",
        "field3": "Εξοδακαυσίμων",
        "field4": ""
    },
    "maria_anagnostou": {
        "fname": "ΑναγνώστουΜαρία",
        "field1": "Διαφήμισηεπιχείρησης",
        "field2": "Τεχνικόςεπιχείρησης",
        "field3": "Μηχανικόςεπιχείρησης",
        "feild4": ""
    }
}

// Valid JSON http://jsonlint.com/

To get your JSON file see: Get JSON data from external URL and display it in a div as plain text

If you want to treat your "JSON" like an JS object than yes, you can call it using

<script src="myJson.js"></script>
<script>
    console.log(users); // Works
</script>
