Delete a Json line using javascript

My API retrieve a Json like this : 

{
 "name": "API",
 "count": 30,
 "newdata": true,
 "lastrunstatus": "success",
 "thisversionstatus": "success",
 "thisversionrun": "Mon Sep 07 2015 20:31:07 GMT+0000 (UTC)",
 "results": {
 "collection1": [
  {
    "name": "Item1",
    "power": "210",
    "name": {
      "href": "http://picture.item42.com/item42.html",
      "text": "Hammer of god"
    },
    "desc": "Iron Hammer",
    "index": 1,
    "url": "http://picture.item42.com/"
  },
  {
      "name": "Item2",
    "power": "230",
    "name": {
      "href": "http://picture.item42.com/item43.html",
      "text": "Sword of god"
    },
    "desc": "Iron sword",
    "index": 1,
    "url": "http://picture.item43.com/"
  }
 ]
}

I would like to delete the line "url" for each one, and delete le "href" property for the name to have "name" : "Hammer of god";

I try this and many other way (first step to delete the url): data contains the Json that I copied upper

function transform(data) {
var yourArray = data.results.collection1;
    var p = 0;
    var i = 0;
    var destArr=[];
        var srcArr=yourArray;
        for(i in srcArr){ 
         if(srcArr[i].url) 
            destArr[p]=srcArr[i];
            p++;
      }
    srcArr=destArr;
  return srcArr;
}

Maybe its better to use data.results.collection1.filter ? actually my code return the json without the header but still with the url row

Try the following: 

jsonData.results.collection1.map(function(obj, index){
  delete obj.url;
  obj.name = obj.name.text;
  return obj;
});
console.log(jsonData);

you should use the JSON delete method for what you want to achieve: Where data is your json object:

data.results.collection1.forEach(function(el) {
   delete el.url
   delete el.name.href
});

You can simply use a second forEach loop in case you need to iterate through multiple collections.

Simply go through your json.result.collection1 and remove href on each name and url:

for(item in json.results.collection1) {
    delete json.results.collection1[item].name.href
    delete json.results.collection1[item].url;
}

var json = document.getElementById('json').value;
var obj = JSON.parse(json);

obj.results.collection1.forEach(function(entry) {
    delete entry.url;
    delete entry.name.href;
});

document.getElementById('result').value = JSON.stringify(obj);

Use the delete keyword to delete a property from the JSON. 

var jsonObj = JSON.parse('your json string');
delete jsobObj.whateveryYourpropertyName;
