Convert $.param in angularjs

Question

Before I am using JQuery and I use this to send URL with parameter

window.location = myUrl + $.param({\"paramName\" : \"ok\",\"anotherParam\":\"hello\"});
         


        

Answer 1

I found this function useful for url serialization. Will also work for nested objects.

var param = function(obj) {

  if ( ! angular.isObject( obj) ) { 
    return( ( obj== null ) ? "" : obj.toString() ); 
  }
  var query = '', name, value, fullSubName, subName, subValue, innerObj, i;

  for(name in obj) {

    value = obj[name];
    if(value instanceof Array) {
      for(i in value) {

        subValue = value[i];
        fullSubName = name + '[' + i + ']';
        innerObj = {};
        innerObj[fullSubName] = subValue;
        query += param(innerObj) + '&';
      }

    } else if(value instanceof Object) {
      for(subName in value) {

        subValue = value[subName];
        fullSubName = name + '[' + subName + ']';
        innerObj = {};
        innerObj[fullSubName] = subValue;
        query += param(innerObj) + '&';
      }
    }
    else if(value !== undefined && value !== null)
      query += encodeURIComponent(name) + '=' + encodeURIComponent(value) + '&';
  }

  return query.length ? query.substr(0, query.length - 1) : query;
};
