Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

  <input type="text" name="last_name" />
</div>

The peekfield([options], [fields]) Function

Initiates peekfield.

Parameters

  • options (Object) (Optional) - An object of options you can set to change how the fields function.

  • fields (String, NodeList, or HTMLElement) (Optional) - The elements to turn into peekfield. If set to a string, that string will be passed to document.querySelectorAll(). (Defaults to [data-peekfield]:not(data-peekfield-ignore))

Examples

window.addEventListener('load', function () {
  // Run with default options and element selector
  peekfield()

  // Run with default options but on a specific element
  peekfield({}, document.getElementsByClassName('my-field'))

  // Run with custom options set (options displayed here are what the defaults are)
  peekfield({
    applyStyles: true,
    closeOnFocusOut: true,
    display: null,
    onClose: null,
    onOpen: null,
    options: {},
    placeholder: null,
    startingTabIndex: 0
  })

  // Run with custom options set only to a specific field
  peekfield({
    options: {
      name: {
        placeholder: 'Please enter your name.'
      }
    }
  })
})

Your best bet would be to check out the source for index.html to get an idea of all the ways peekfield can be used.

Options

These are the options you can set with the options parameter:

  • applyStyles (Default: true) - Set to false to not have the display:none and visibility:hidden styles added/removed on the field and label elements when they are opened/closed.

  • closeOnFocusOut (Default: true) - Set to false to not have the fields close when they lose focus.

  • display (Default: null) - The content to display on the label element when a field has had something entered into one of it's child input elements. Functions exactly the same as the label element's data-peekfield-display attribute with the exception that a function can be used here for more control over what is displayed. If a function is used here, it will be passed field object as the first parameter. This option is used as a fallback when the label element does not have a data-peekfield-display attribute.

  • onClose (Default: null) - A function to run when a field is closed. Receives the event as the first parameter and the field object as the second.

  • onOpen (Default: null) - A function to run when a field is opened. Receives the event as the first parameter and the field object as the second.

  • opened (Default: false) - Set to true to have the field be opened when first initiated.

  • options (Default: {}) - An object with keys set to field element identifiers (the data-peekfield attribute) and their values set to an object containing keys and values that you would normally pass to the options parameter. This allows for setting options to specific fields.

  • placeholder (Default: null) - The content to display on the label element when a field has NOT had something entered into one of it's child input elements. Functions exactly the same as the label element's data-peekfield-placeholder attribute with the exception that a function can be used here for more control over what is displayed. If a function is used here, it will be passed the field object as the first parameter. This option is used as a fallback when the label element does not have a data-peekfield-placeholder attribute.

  • startingTabIndex (Default: 0) - A tabindex attribute needs to be set on field and label elements in order for the closeOnFocusOut functionality to work correctly. If a field or label element does not have it's tabindex attribute set, one will be set for each peekfield initiated starting at the index this option is set to unless this option is set to false.

Methods

These methods are attached to the field element when vanishing fields is initiated and can be used to make the field do different things:

  • field.open(triggerEvents) - Opens the field. Pass false as the first parameter to not have the open event fired.

  • field.close(triggerEvents) - Closes the field. Pass false as the first parameter to not have the close event fired.

  • field.toggle(open, triggerEvents) - Opens the field if it is currently closed and closes it if it's currently open. Pass true as the first parameter to open it regardless of it's current state and false to close it. Pass false as the second parameter to not have the open or close event fired.

  • field.getInputValues() - Returns an object containing the values of any inputs inside of the field element.

Properties

These properties are attached to the field element when vanishing fields is initiated and changed when different things happen and can be used to see what state a field is in:

  • field.changed - Is true if field.values doesn't match field.originalValues, and false if they match.

  • field.empty - Is true when the field is considered empty (all child inputs are empty) and false otherwise.

  • field.opened - Is true when the field is currently open and false if it is not.

  • field.originalValues - An object containing the values of any input elements inside of the field element as they were when vanishing fields was first initiated.

  • field.values - An object containing the values of any input elements inside of the field element the last time they were fetched (does not change when field.getInputValues() is ran manually).

  • field.inputs - An array of all child input elements.

Events

These events are fired on the field element when different things happen:

  • open - Fires when the field is opened.

  • close - Fires when the field is closed.

Data Attributes

Attributes can be set on fields to set different options.

The "field" element

This is the element that contains the inputs and any other content you would like to be able to open and close. It is visible when a field is considered open.

  • data-peekfield (Required) - This is the identifier for the field and needs to be set.

  • data-peekfield-apply-styles - Set to false to not have the display:none and visibility:hidden styles added/removed on the field and label elements when they are opened/closed. (Overrides the applyStyles option)

  • data-peekfield-close-on-focus-out - Set this to false to not close the field when it loses focus. (Overrides the closeOnFocusOut option)

  • data-peekfield-ignore - Add this to a field element to have it not be initiated by the default fields parameter passed to the peekfield function. This is useful if you would like to initiate this field separate from the rest.

The "label" element

This is the element that contains the content that is visible when a field is considered closed. By default, this element should be left empty as it will have it's content filled out for you depending on options and input values set. This element however is not required.

  • data-peekfield-for (Required) - If using the label element, this attribute is required and should be set to the field's identifier.

  • data-peekfield-display - The content to display when the field element is considered to be NOT empty. An input's value can be displayed by entering it's name between two curly braces (ie. Your name is: {field_name}). You can also define default text to display if that specific field is empty after a pipe character (ie. Your name is: {field_name|Bob}). Furthermore, if the input value is an array (like with checkboxes or multi-select fields), you can define a string or character to separate them with (ie. Your favorite colors are: {colors|None| and }), otherwise a comma will be used. (Overrides the display option)

  • data-peekfield-placeholder - The content to display when the field element is considered to be empty. (Overrides the placeholder option)

Trigger elements

These attributes can be set on any elements (inside or outside of a field/label element) to have them perform different actions.

  • data-peekfield-open - Set this to a field's identifier to have that field be opened when this element is clicked.

  • data-peekfield-close - Set this to a field's identifier to have that field be closed when this element is clicked.

  • data-peekfield-toggle - Set this to a field's identifier to have that field's open status be toggled when this element is clicked.

Input elements

  • data-peekfield-ignore - This attribute can be set on any input elements inside of a field element to be ignored completely (such as hidden fields).

Classes

peekfield does not apply any styling and leaves that up to you (except for the display:none and visibility:hidden styles if the applyStyles option isn't set to false), however these classes are applied to both the field and input elements when different things happen.

  • open - Added when a field is considered open, otherwise removed. You can also add this class to the field element to have the field be opened when first initiated.

  • empty - Added when a field is considered empty, otherwise removed.

  • changed - Added when a field's child input values have changed since peekfield has been initiated, otherwise removed.
