}


var name=prompt('Enter the name of pokemon')
pokeinfo(name)

<pre>var pokemongo=
{
  "pokemon": [{
    "id": 1,
    "num": "001",
    "name": "Bulbasaur",
    "img": "http://www.serebii.net/pokemongo/pokemon/001.png",
    "type": [
      "Grass",
      "Poison"
    ],
    "height": "0.71 m",
    "weight": "6.9 kg",
    "candy": "Bulbasaur Candy",
    "candy_count": 25,
    "egg": "2 km",
    "spawn_chance": 0.69,
    "avg_spawns": 69,
    "spawn_time": "20:00",
    "multipliers": [1.58],
    "weaknesses": [
      "Fire",
      "Ice",
      "Flying",
      "Psychic"
      ]
			  }]

	

};

var pokeinfo=function(name)
{
	var isfound=false;

	for(x in pokemongo){
		
		if(pokemongo[x]['name']==name){
			isfound=true;
			break;
		}
		else{
			isfound=false;
		}
	}// end of for in loop

if(isfound==true){
	
	alert(pokemongo.pokemon[x])
}
else{
	alert(" info not available ")
}

}


var name=prompt('Enter the name of pokemon')
pokeinfo(name)

x is not an index in pokemongo
Try:

JavaScript

var pokeinfo=function(name)
{
	var isfound=false;

	for(x in pokemongo){
		
		if(x['name']==name){
			isfound=true;
			break;
		}
		else{
			isfound=false;
		}
	}// end of for in loop

Your code do not behave the way you expect, and you don't understand why !

There is an almost universal solution: Run your code on debugger step by step, inspect variables.
The debugger is here to show you what your code is doing and your task is to compare with what it should do.
There is no magic in the debugger, it don't know what your is supposed to do, it don't find bugs, it just help you to by showing you what is going on. When the code don't do what is expected, you are close to a bug.
To see what your code is doing: Just set a breakpoint and see your code performing, the debugger allow you to execute lines 1 by 1 and to inspect variables as it execute.

The debugger is here to only show you what your code is doing and your task is to compare with what it should do.

Solution 2

Based on the JSON object, the code need to be updated to use several iteration to get the desire result using JavaScript. Also. there are flaws in the code, example, the x is not available/not in scope after the loop.

Here is an example
