How to reset object value to null in angularjs?

This is my code

var data={};

data={stdId:"101"};
data={empId:"102"};
data={deptId:"201"};

I have a data object getting data from services with one key only. but key names are different like stdId or empId ,etc.
I want to assign empty value to stdId or empId ,etc. like data={stdId:""} .
The key names are changed dynamically based on services.

You can use for..in loop to iterate over data object using key.

for(var key in data){
  if(data.hasOwnProperty(key)){
     data[key] = '';
  }
}

Note: This will set every property of data object to ''

As I understand your question, you won't know the name of the key in each object and there is only ever one. To solve your problem:

data[Object.keys(data)[0]] = ''

This will assign the value of the key to null.

Not entirely sure what you are trying to achieve, but if you know the name of the property you could use:

data['stdId'] = '';

or

data.stdId = '';

If you do not know the property name, but you still want to keep the property names on the object you could use:

for(var prop in data) {
  if(data.hasOwnProperty(prop)) {
    data[prop] = '';
  }
}

data.stdId = null;

or

data.stdId = '';

or

data = { stdId };

Have you tried those?
