用jQuery更改输入框的值

Question

I got a form which is being created by some class files, it only creates the classname. However the background image is being set but with the value is being typed, I want to hide the background image. I am trying this piece of script but it does not work:

 <input type="text" value="" name="b_fname">

 background-image:
 url("/site/vitiscellars/images/basic_theme/your_name_bg.jpg");

This is my piece of test code:

javascript

 var $j = jQuery.noConflict();
 $j(document).ready(function() {

 $j('.b_fname').click(function() {  
     alert('Handler for called'); });     
 });

Do know why this piece of code is not working.

Answer 1

you have name="b_fname" but no class. Add class="b_fname" or change your selector to:

$j('[name=b_fname]')

Answer 2

Use class=b_fname in your html for the text box.

Otherwise in your jquery selector do

$j('input[name="bfname"]')

Answer 3

$j('.b_fname') selects class, not name. To get the class, you have to add the class to the input, ie <input type="text" value="" class="b_fname" name="b_fname"> .

Subsequently, you could select the element by name using $j('input[name="b_fname"]') .
