how to define variable in jquery

Question

I would like to know how to declare a variable in jQuery

The code I am currently using is

$.name = 'anirudha';
alert($.name);

That code works fine, but if I write it as

$.name = document.myForm.txtname.value;
alert($.name);

Then my code does not work.

Answer 1

var name = 'john';
document.write(name);

it will write the variable you have declared upper

Answer 2

In jquery, u can delcare variable two styles.

One is,

$.name = 'anirudha';
alert($.name);

Second is,

var hText = $("#head1").text();

Second is used when you read data from textbox, label, etc.
