javascript HTML get value

Question

I have the following in my HTML5 code which makes use of javascript:

     var myObj = localStorage[dataObj];
     alert(myObj);
     alert(myObj.City);

When I do alert(myObj) it shows {"ID":68,"City":New York} which is what is in var. I now need to get the value of City. I do the following but it shows as undefined: alert(myObj.City); I also tried

    alert(myObj[0]:City) but that did not work as well

@DanielA.White: If alert showed that, it's a string. If you alert an object, you get [object Object]. — gen_Eric

myObj is a string, it needs to be parsed into an object.

myObj = JSON.parse(myObj);
console.log(myObj.City);

P.S. console.log is much better for debugging than alert.

IE doesn't seem to support console.log ?

@AlanFoster: IE (< 9, I think) only supports it after you open the developer tools (F12).

Looks like you have a string, rather than an object. Load it with:

myObj = JSON.parse(myObj);
alert(myObj.City);
