Question

Ensure that the default value in the text box remains unchanged until new text is input by utilizing jQuery

Can you please review my code snippet on http://jsfiddle.net/7995m/? The issue I'm facing is that the default text in the text box disappears as soon as it's clicked. What I want is for the default text to remain until the user starts typing. Here's the code I've written:

$(".defaultText").focus(function(srcc)
{
    if ($(this).val() == $(this)[0].title)
    {
        $(this).removeClass("defaultTextActive");
        $(this).val("");
    }
});

$(".defaultText").blur(function()
{
    if ($(this).val() == "")
    {
        $(this).addClass("defaultTextActive");
        $(this).val($(this)[0].title);
    }
});

$(".defaultText").blur();

Start using the HTML5 placeholder attribute by checking out this resource: http://davidwalsh.name/html5-placeholder

This attribute is commonly utilized in web applications.

If your targeted browser doesn't support placeholders, consider creating a polyfill with modernizr to ensure compatibility with the html5 attribute. Here's an example of a polyfill using jquery: https://github.com/mathiasbynens/jquery-placeholder

You can explore additional polyfills for placeholders and other html5 attributes here: https://github.com/Modernizr/Modernizr/wiki/HTML5-Cross-Browser-Polyfills

Refer to modernizr through this link:

Once you implement the polyfill, modernizr will check if the browser supports the placeholder attribute. If not, the polyfill will mimic its functionality. This approach keeps your HTML clean without custom solutions that may cause compatibility issues with future browsers.

Using a polyfill like this is the optimal choice. While custom solutions work initially, relying on a polyfill prevents potential issues in the long run. It ensures your application remains functional even as new browsers emerge, maintaining the same capabilities across different browser versions. Additionally, it enhances the readability of your HTML code.

check out this working fiddle

To improve the functionality, consider replacing the focus with keydown. While a placeholder is a good option, keep in mind that IE7,8,9 do not support it. Instead of using JavaScript polyfills, you can stick with the current code provided.

$(".defaultText").keydown(function(srcc) {
    if ($(this).val() == $(this)[0].title) {
        $(this).removeClass("defaultTextActive");
        $(this).val("");
    }
});

$(".defaultText").blur(function() {
    if ($(this).val() == "") {
        $(this).addClass("defaultTextActive");
        $(this).val($(this)[0].title);
    }
});

$(".defaultText").blur();

For achieving this specific behavior, consider using the following script within your focus event:

$(".defaultText").keydown(function(event)
{
    $(this).removeClass("defaultTextActive");
    $(this).val("");
