Processing a JSON array of objects in AngularJS

When using Angular's fromJson function to parse a JSON string, I encountered an issue. If the JSON is a simple array like "[1, 2]", the code works fine. However, I need to work with an array of dictionaries instead.

    var str = "[{'title':'hi'}, {'title':'what'}]"
    alert(str) //1
    alert(str.length) //2
    var j = angular.fromJson(str)
    alert(j) //3
    alert(j.length) //4

Alerts for 1 and 2 show the string representation, but alerts for 3 and 4 indicate that fromJson has encountered an error.

Note: This issue is unrelated to JSON.parse or $._parseJSON functions; I must use the Angular method for specific reasons.

Answer №1

The reason for this issue is due to the invalid JSON format you are using. In order for JSON to be considered valid, properties must be enclosed in double quotes rather than single quotes. Therefore, you should try utilizing

  '[{"title":"hello"}, {"title":"howdy"}]'

Refer to this documentation for more information.

Remember that property names should be double-quoted strings; also, avoid placing trailing commas.
