The Placer Toolkit alpha has arrived! 🎉
Plenty of changes are coming your way—some big, some breaking, some even nuclear! Beware the changelog…

Bring it on!

Copy Button

<pc-copy-button>

0.5.1

experimental

Copies text data to the clipboard when the user clicks the trigger.

<pc-copy-button value="Placer Toolkit rocks!"></pc-copy-button>

Code

Edit

Copy buttons use the browser’s clipboard.writeText() method, which requires a secure context (HTTPS) in most browsers.

Demos#

Custom labels#

Copy buttons display feedback in a tooltip. You can customise the labels using the copy-label, success-label and error-label attributes.

<pc-copy-button
    value="Custom labels are easy"
    copy-label="Click to copy"
    success-label="You did it!"
    error-label="Whoops, didn’t work for some reason."
></pc-copy-button>

Code

Edit

Custom icons#

Use the copy-icon, success-icon and error-icon slots to customise the icons that get displayed for each state. You can use <pc-icon> or your own images.

<pc-copy-button value="Copied from a copy button with custom icons">
    <pc-icon
        library="default"
        icon-style="regular"
        name="clipboard"
        slot="copy-icon"
    ></pc-icon>
    <pc-icon
        library="default"
        icon-style="regular"
        name="thumbs-up"
        slot="success-icon"
    ></pc-icon>
    <pc-icon
        library="default"
        icon-style="regular"
        name="thumbs-down"
        slot="error-icon"
    ></pc-icon>
</pc-copy-button>

Code

Copying values from other elements#

Normally, the data that gets copied will come from the component’s value attribute, but you can copy data from any element within the same document by providing its id to the from attribute.

When using the from attribute, the element’s textContent will be copied by default. Passing an attribute or property modifier will let you copy data from one of the element’s attributes or properties instead.

To copy data from an attribute, use from="id[attribute]" where id is the id of the target element and attribute is the name of the attribute you’d like to copy. To copy data from a property, use from="id.property" where id is the id of the target element and property is the name of the property you’d like to copy.

<!-- Copies the span’s textContent -->
<span class="pc-align-items-center pc-gap-s">
    <span id="my-phone">+1 555 555 0123</span>
    <pc-copy-button from="my-phone"></pc-copy-button>
</span>

<br />

<!-- Copies the input’s value property -->
<span class="pc-align-items-center pc-gap-s">
    <pc-input
        type="text"
        id="my-input"
        value="User input"
        style="display: inline-block; max-inline-size: 300px"
    ></pc-input>
    <pc-copy-button from="my-input.value"></pc-copy-button>
</span>

<br />

<!-- Copies the link’s href attribute -->
<span class="pc-align-items-center pc-gap-s">
    <a href="https://example.com" id="my-link">Example website</a>
    <pc-copy-button from="my-link[href]"></pc-copy-button>
</span>

Code

Edit

Handling errors#

A copy error will occur if the value is an empty string, if the from attribute points to a non‐existent id or if the browser rejects the operation for any reason. When this happens, the pc-error event will be emitted.

This example demonstrates what happens when a copy error occurs. You can customise the error label and icon using the error-label attribute and the error-icon slot, respectively.

<pc-copy-button from="i-do-not-exist"></pc-copy-button>

Code

Edit

Disabled#

Copy buttons can be disabled by adding the disabled attributes.

<pc-copy-button value="You can’t copy me!" disabled></pc-copy-button>

Code

Edit

Changing feedback duration#

A success indicator is briefly shown after copying. You can customise the length of time the indicator is shown using the feedback-duration attribute.

<pc-copy-button
    value="Placer Toolkit rocks!"
    feedback-duration="250"
></pc-copy-button>

Code

Edit

Custom styles#

You can customise the button to your liking with CSS.

<pc-copy-button value="I’m so stylish!" class="custom-pink-copy-button">
    <pc-icon
        library="default"
        icon-style="solid"
        name="asterisk"
        slot="copy-icon"
    ></pc-icon>
    <pc-icon
        library="default"
        icon-style="solid"
        name="check"
        slot="success-icon"
    ></pc-icon>
    <pc-icon
        library="default"
        icon-style="solid"
        name="xmark"
        slot="error-icon"
    ></pc-icon>
</pc-copy-button>

<style>
    pc-copy-button.custom-pink-copy-button::part(button) {
        background-color: #ff1493;
        color: #fff;
        border: 2px solid;

        border-inline-start-color: #ff7ac1;
        border-inline-end-color: #ad005c;
        border-radius: 6px;
        box-shadow: 0 2px 10px #0002;
        transition: all var(--pc-transition-fast) ease-in-out;
    }

    pc-copy-button.custom-pink-copy-button::part(button):hover {
        transform: scale(1.05) rotate(-1deg);
    }

    pc-copy-button.custom-pink-copy-button::part(button):active {
        border-block-start-color: #ad005c;
        border-block-end-color: #ff7ac1;
        border-inline-start-color: #ad005c;
        border-inline-end-color: #ff7ac1;
        transform: translateY(1px) rotate(-1deg);
    }

    pc-copy-button.custom-pink-copy-button::part(button):focus-visible {
        outline: 2px dashed deeppink;
        outline-offset: 2px;
    }
