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.
jQuery is just a javascript library that makes some extra stuff available when writing javascript - so there is no reason to use jQuery for declaring variables. Use "regular" javascript:
var name = document.myForm.txtname.value;
alert(name);
EDIT: As Canavar points out in his example, it is also possible to use jQuery to get the form value:
var name = $('#txtname').val(); // Yes, it's called .val(), not .value()
given that the text box has its id attribute set to txtname. However, you don't need to use jQuery just because you can.
Try this :
var name = $("#txtname").val();
alert(name);
Here's are some examples:
var name = 'india';
alert(name);
var name = $("#txtname").val();
alert(name);
Taken from http://way2finder.blogspot.in/2013/09/how-to-create-variable-in-jquery.html
in jquery we have to use selector($) to declare variables
var test=$("<%=ddl.ClientId%>");
here we can get the id of drop down to j query variable
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.
Remember jQuery is a JavaScript library, i.e. like an extension. That means you can use both jQuery and JavaScript in the same function (restrictions apply).
You declare/create variables in the same way as in Javascript: var example;
However, you can use jQuery for assigning values to variables:
var example = $("#unique_product_code").html();
Instead of pure JavaScript:
var example = document.getElementById("unique_product_code").innerHTML;
You can also use text() to set or get the text content of selected elements
var text1 = $("#idName").text();
var name = 'john';
document.write(name);
it will write the variable you have declared upper
