How to get form elements by name in jquery?

I have this form

var sformElem = $('form[name="search_form"]')[0];

I am able to access the form element of name say 'fieldname' by

var inputField = sformElem.fieldname;

    if (inputField) {  // true
    alert("this is true"); 
    }

But when I am trying to acess the value using val() method of jquery, javascript crashes.

inputField.val() is not defined.

but doing inputField.value returns the value

Why didn't val() method work? Where am I making a mistake? Also, please suggest the most appropriate of accesing form elements by name.

One method I know of is

$("#form2 input[name=name]")

but here we get the form by id and input fields by name.

I want to get both form and form elements by name.

get it done by using

$('inputField id or class').attr('attribute');

the class or input field value can be called by the .attr() method so that you can have that value in some variable.

Why didn't val() method work?

inputField.val() returned "not defined" because inputField is a DOM element and not a jQuery object. DOM elements don't have val() method. So the error is correct.

You need to convert it into a jQuery object. like

$(inputField).val()

I want to get both form and form elements by name.

var elem = $('form[name="search_form"] input[name=name]');

var x = $("form[name = "search_form"]).get(0)

$("form[name = "search_form"]).get(0)

Since it is not a jquery object val will not work.Inorder to use val you have to make it a jquery object.

Like

$(x).val();

With this you will get the DOM Element

Do $(inputField).val() as this passes the DOM Element through to jQuery therfore making val available
