A lib to create dynamic form to submit

dynamicForm.js

function DynamicForm(url) 
{
    var self = this;
    var fields = [];

    self.target = "";
    self.method = "get";
    self.action = url;
    self.addField = function(name, value) {
        fields.push({name: name, value: value});

        return self;
    };

    self.remoteField = function(name) {
        fields = fields.filter(function(item) {
            return item.name != name;
        });

        return self;
    };

    self.getFields = function() {
        return fields;
    };
}

DynamicForm.prototype.submit = function submit () {
    var form = document.createElement("form");
    form.action = this.action;
    form.method = this.method;
    form.target = this.target;

    this.getFields().forEach(function(item) {
        var field = document.createElement("input");
        field.type = "hidden";
        field.name = item.name;
        field.value = item.value;

        form.appendChild(field);
    });

    form.submit();
}
