Question

I have multiple text box like this. I want to apply the text on blur and empty when it get focused. I can able to achieve this for single text box. How i can pass the current element id instead of the hard coding the “#name” value in JavaScript function ?

$(document).ready(function(){


    $('#Name').focus(function()
    {
         var $ele = $(this).attr('id');
            $(this).val('');
            $(this).css('color', '#000000');
    });

    $('#Name').blur(function()
    {
           var $ele = $(this).attr('id');
            $(this).val($ele);
            $(this).css('color', '#a9a9a9')
    });
});



<input id="Name" type="text" value="" name="Name">
<input id="Phone" type="text" value="" name="Phone" >
<input id="Email" type="text" value="" name="Email">

You can select all input by $('input') and you can put filter text inputs using [type="text"]; You can take benefits of jQuery chaining.

$(document).ready(function(){   

    $('input[type="text"]').focus(function()
    {
         var $ele = $(this).attr('id');
            $(this).val('');
            $(this).css('color', '#000000');
    }).blur(function()
    {
           var $ele = $(this).attr('id');
            $(this).val($ele);
            $(this).css('color', '#a9a9a9')
    });
});

You can directly set value of input fields in html

<input id="Name" type="text" value="Name" name="Name">

OR Apply default values on page load as:

$('input[type="text"]').each(function(){
   var $ele = $(this).attr('id');
                $(this).val($ele);
                $(this).css('color', '#a9a9a9')

});

HTML

<input id="Name" type="text" value="" name="Name">
<input id="Phone" type="text" value="" name="Phone" >
<input id="Email" type="text" value="" name="Email">
