# Popover 弹出框

Add small overlays of content, like those on the iPad, to any element for housing secondary information.

# Example


Popovers whose both title and content are zero-length are never displayed.

Click the button below to toggle popover:


Hello world!

  <div class="uiv">
    <btn type="primary" id="btn">Popover</btn>
    <popover title="Title" target="#btn">
      <template slot="popover">
        <h1>Hello world!</h1>

# Trigger target

Order to decide the popover trigger:

  1. Use target if exist.
  2. Use element in default slot with data-role="trigger" attribute if exist.
  3. Use the first element present in default slot.

A target can be:

  • Selector that can be recognized by querySelect.
  • Reference to Element.
  • Reference to Component.

# Directive

You can also simply use popovers via v-popover directive:

  <div class="uiv">
    <btn v-popover="{title:'Title', content:'Popover content'}" type="primary">Popover</btn>

# With empty title

If you don't want the title of popover, just leave the title prop unset or blank.

  <div class="uiv">
    <btn v-popover="{content:'Popover without a title'}" type="primary">Popover</btn>

# Placements

Supported placements:

  • top (Default)
  • right
  • bottom
  • left
  <div class="uiv">
    <btn v-popover.left="{title:'Title', content:'Popover on left'}" type="primary">Left</btn>
    <btn v-popover.top="{title:'Title', content:'Popover on top'}" type="primary">Top</btn>
    <btn v-popover.bottom="{title:'Title', content:'Popover on bottom'}" type="primary">Bottom</btn>
    <btn v-popover.right="{title:'Title', content:'Popover on right'}" type="primary">Right</btn>

# Auto placement

Popover will try to find the best placement for displaying while auto-placement is set to true (by default) base on the default placement setting. Useful while there does not have enough space to show the entire popover content.

auto-placement try order: right -> bottom -> left -> top, and use the set one if none of these matched.

# Viewport

Keeps the popover within the bounds of this element.

  <div class="uiv" id="popover-viewport">
    <btn v-popover="{title:'Title', content:'Popover auto', viewport:'#popover-viewport'}" type="primary">Auto</btn>
    <btn v-popover.left="{title:'Title', content:'Popover on left', viewport:'#popover-viewport'}" type="primary">Left</btn>
    <btn v-popover.top="{title:'Title', content:'Popover on top', viewport:'#popover-viewport'}" type="primary">Top</btn>
    <btn v-popover.bottom="{title:'Title', content:'Popover on bottom', viewport:'#popover-viewport'}" type="primary">Bottom</btn>
    <btn v-popover.right="{title:'Title', content:'Popover on right', viewport:'#popover-viewport'}" type="primary">Right</btn>
    <btn v-popover="{title:'Title', content:'Popover auto', viewport:'#popover-viewport'}" type="primary">Auto</btn>
<style scoped>
  #popover-viewport {
    display: inline-block;
    padding: 20px;
    background-color: #eee;

# Triggers

Supported triggers:

  • hover show on mouseenter, hide on mouseleave.
  • focus show on focus, hide on blur.
  • hover-focus combination of hover and focus trigger.
  • click toggle on trigger click.
  • outside-click (Default) same as click, but not close on popover click and close on outside click.
  <div class="uiv">
    <btn v-popover="{title:'Title', content:'Popover content'}" type="primary">Outside-Click (Default)</btn>
    <btn v-popover.hover="{title:'Title', content:'Popover content'}" type="primary">Hover</btn>
    <btn v-popover.focus="{title:'Title', content:'Popover content'}" type="primary">Focus</btn>
    <btn v-popover.hover-focus="{title:'Title', content:'Popover content'}" type="primary">Hover-Focus</btn>
    <btn v-popover.click="{title:'Title', content:'Popover content'}" type="primary">Click</btn>

# Manual trigger

Set trigger prop to manual to disable all the event listeners, and controls popover show / hide only by v-model change.


Popover content

  <section class="uiv">
    <popover title="Title" trigger="manual" v-model="show">
      <btn>You Can't Trigger Popover Here...</btn>
      <template slot="popover">
        <p>Popover content</p>
    <btn type="primary" @click="show = !show">Toggle Popover</btn>
