jQuery Plugins

This is a collection of useful jQuery plugins

Placeholder

Mimics Safari's placeholder attribute on other browsers.

Usage

On Javascript:

$("input#name").placeholder("Type your name");

On CSS, you can style the field using the .placeholder class:

.placeholder {
    color: #aaa;
}

Disable multiple submit

Prevents form from being submitted twice.

Usage

$(":submit").disableMultipleSubmit()
$(":submit").disableMultipleSubmit("Still processing your request")

Render

A simple rendering plugin that replaces the object attributes/elements automatically.

Usage

Create views that the plugin can use:

$.render.views["user"] = "<div class='user' id='user-@id'>
    <h1 class='name'></h1>\
    <img alt="@name" class="avatar_url" />
</div>";

Then you can render this view using the $.render() function.

$.render("user", {name: "John Doe", id: 1, avatar_url: "john.png"});

The snippet above will replace all @attr placeholders. When a given tag is an image, then the replaced value will be a src attribute.

You can use inline views. Just specify the template and let the render plugin do the rest.

$("div.user:first").render(records);

There are two callbacks; one for formatting values and other that will be dispatched when the rendering is completed. The example above will uppercase all attribute values and display an alert when rendering is done.

var user = {name: "John Doe", id: 1, avatar_url: "john.png"};
$.render("user", user, {
    formatter: function(attr, value) { return value.toString().toUpperCase(); },
    ready: function(renderedView) { alert("Finished rendering!"); }
});

• Placeholder
  • When input is a password field, switch type to text, so the text can be displayed - http://vivin.net/2009/05/26/jquery-tip-changing-the-type-attribute-of-an-input-element/
