Unable To Solve Error " Uncaught Syntaxerror: Unexpected Token O "

I am currently practicing using Javascript/Dojo. However, I have an error that I am unable to solve: Uncaught SyntaxError: Unexpected token o I have made a quick snippet of my pr

Solution 1:

You're trying to parse a JavaScript object. JSON.parse is for parsing a JSON string representing a JavaScript-like object.

Just skip the parsing altogether:

alert(data.list[1].Name);

---

On a related note: you might be interested in reading There's no such thing as a "JSON Object".

Solution 2:

Error is once declared as datatype json, it parses for you.

so : it would be something like this

<span style="text-decoration:line-through;">var obj = JSON.parser(data)</span>

 success: function(data){

  var obj = JSON.parser(data)

  alert(obj.data)

}

Solution 3:

try :

alert(data.list[1].Name);

instead of:

var jsonData = JSON.parse(data);
 alert(jsonData.list[1].Name);

data is already a javascript object not a string

Solution 4:

That's because you are parsing a plain object, and not a string, as expected. In this case you just have to:

alert(jsonData.list[1].Name);

In this case, to use the JSON.parse method you should've been using this string:

var stringifiedJson =var data ="{"+"\"list\": {"+"\"1\": {"+"\"Relevance\": \"Low\","+"\"id\": 1,"+"\"Name\": \"Inorganic\""+"},"+"\"2\": {"+"\"Relevance\": \"Low\","+"\"id\": 2,"+"\"Name\": \"Mobile\""+"}"+"}"+"}";

var jsonData =JSON.parse(stringifiedJson);
alert(jsonData.list[1].Name);
