javascript - How to remove space in keys of a JSON object

Question

I have an output like below:

output = {
  "New Classroom": [{
    "Name": "Apple",
    "Age": "6",
    "Percentage": "24.00%"
  }, {
    "Name": "Orange",
    "Age": "5",
    "Percentage": "9.88%"
  }, {
    "Name": "Green",
    "Age": "2",
    "Percentage": "27.27%"
  }, {
    "Name": "Grey",
    "Age": "6",
    "Percentage": "12.63%"
  }]
}

How do I replace New Classroom with NewClassroom and the New classroom is not always a "NewClassroom".It may be different text

ob = JSON.parse(output);

alert(Object.keys(ob))

when I do this, I'm getting Newclassroom as the key

Answer 1

You can loop through the top-level property names in the object you receive, detect any with spaces, and remove the spaces. (You don't need to, they're perfectly valid property names, but you can if you want.)

var output = { "New Classroom": [{"Name": "Apple","Age": "6","Percentage": "24.00%"},{"Name": "Orange","Age": "5","Percentage": "9.88%"},{"Name": "Green","Age": "2","Percentage": "27.27%"},{"Name": "Grey","Age": "6","Percentage": "12.63%"}]};
var name, newName;
// Loop through the property names
for (var name in output) {
  // Get the name without spaces
  newName = name.replace(/ /g, "");
  // If that's different...
  if (newName != name) {
    // Create the new property
    output[newName] = output[name];
    // Delete the old one
    delete output[name];
  }
}
console.log(output);
