Slots
header/footer
Slots for injecting content around the results/input. Useful for header/footer like slots or empty state.
<vue-autosuggest ...>
<template slot="before-input"> content before the <input /> goes here </template>
<template slot="after-input"> content after the <input /> goes here </template>
<template slot="before-suggestions"> content before the <ul> goes here </template>
<template slot="before-section-<section.name e.g. 'default'>"> section header content for specific section goes here </template>
<template slot="after-section-<section.name e.g. 'default'>"> footer content goes here for specific section. </template>
<template slot="after-section"> Default footer content for all sections </template>
<template slot="after-suggestions"> content after the <ul> goes here </template>
</vue-autosuggest>
Adding labels
It is common in forms to add a label next to the <input /> tag for semantic html / accessibility. You can use the before-input slot to accomplish this in conjunction with the inputProps.id:
<vue-autosuggest ...>
<template slot="before-input">
<label :for="inputProps.id">Search here:</label>
</template>
...
</vue-autosuggest>
suggestion item (i.e. default slot)
Used to style each suggestion inside the <li> tag. Using scoped slots you have access to the suggestion item inside the v-for suggestions loop. This gives you the power of Vue templating, since vue-autosuggest does not have an opinion about how you render the items in your list.
<vue-autosuggest>
<template slot-scope="{suggestion}">
<!-- suggestion.name corresponds to which section the item is in -->
<div v-if="suggestion.name === 'blog'">
<!-- suggestion.item corresponds to the suggestion object -->
<a target="_blank" :href="suggestion.item.url">{{suggestion.item.value}}</a>
</div>
<div v-else>{{suggestion.item}}</div>
</template>
</vue-autosuggest>
This slot will be overridden when the
render-suggestionprop is used.
Props
| Prop | Type | Required | Description |
|---|---|---|---|
suggestions |
Array | ✓ | Suggestions to be rendered. e.g.suggestions: [{data: ['harry','ron','hermione']}] |
input-props |
Object | ✓ | Add props to the <input>. |
section-configs |
Object | Define multiple sections <input>. |
|
render-suggestion |
Function | Tell vue-autosuggest how to render inside the <li> tag. Overrides what is inside the default suggestion template slot. |
|
get-suggestion-value |
Function | Tells vue-autosuggest what to put in the <input/> value |
|
should-render-suggestions |
Function | Tell vue-autosuggest if it should render the suggestions results popover | |
component-attr-id-autosuggest |
String | id of entire component |
|
component-attr-class-autosuggest-results-container |
String | class of container of results container |
|
component-attr-class-autosuggest-results |
String | class of results container |
|
component-attr-prefix |
String | prefix to be used for results item classes/ids. default: autosuggest |
inputProps
| Prop | Type | Required | Description |
|---|---|---|---|
id |
String | ✓ | id attribute on <input>. |
| Any DOM Props | * | You can add any props to <input> as the component will v-bind inputProps. Similar to rest spread in JSX. See more details here: https://vuejs.org/v2/api/#v-bind. The name attribute is set to "q" by default. |
sectionConfigs
Multiple sections can be defined in the sectionConfigs prop which defines the control behavior for each section.
| Prop | Type | Required | Description |
|---|---|---|---|
on-selected |
Function | ✓ | Determine behavior for what should happen when a suggestion is selected. e.g. Submit a form, open a link, update a vue model, tweet at Ken Wheeler etc. |
limit |
Number | Limit each section by some value. Default: Infinity |
Below we have defined a default section and a blog section. The blog section has a component type of url-section which corresponds to which component the Autosuggest loads. When type is not defined, Vue-autosuggest will use a built in DefaultSection.vue component.
sectionConfigs: {
'default': {
limit: 6,
onSelected: function(item, originalInput) {
console.log(item, originalInput, `Selected "${item.item}"`);
}
},
'blog': {
limit: 3,
type: "url-section",
onSelected: function() {
console.log("url: " + item.item.url);
}
}
}
renderSuggestion
This function can be used to tell vue-autosuggest how to render the html inside the <li> tag when you do not want to use the default template slot for suggestions but would rather have the power of javascript / jsx.
In its most basic form it just returns an object property:
renderSuggestion(suggestion) {
return suggestion.name;
},
But usually it returns a JSX fragment, which is transformed into a virtual node description with babel-plugin-transform-vue-jsx:
renderSuggestion(suggestion) {
return <div style={{ color: "red" }}>{suggestion.name}</div>;
},
If you're not using babel-plugin-transform-vue-jsx, you can create the virtual node description yourself:
renderSuggestion(suggestion) {
return this.$createElement('div', { 'style': { color: 'red'} }, suggestion.name);
},
getSuggestionValue
This function will tell vue-autosuggest what to put in the <input/> as the value.
getSuggestionValue(suggestion) {
return suggestion.item.name;
},
shouldRenderSuggestions
This function will tell vue-autosuggest if it should display the suggestions popover
/**
* @param {Array} size - total results displayed
* @param {Boolean} loading - value that indicates if vue-autosuggest _thinks_ that the
* the popover should be open (e.g. if user hit escape, or
* user clicked away)
* @returns {Boolean}
*/
shouldRenderSuggestions (size, loading) {
// This is the default behavior
return size >= 0 && !loading
}
Events
Below are the list of supported events. @ is short-hand for v-on.
| Prop | Returns | Description |
|---|---|---|
@selected |
suggestionItem, index | suggestion select handler. equivalent to sectionConfigs on-selected but for all items |
@input, @focus, @blur, etc. |
* | there is a transparent wrapper on the underlying <input /> so vue-autosuggest will use any DOM event you pass it for listening. This is implemented using v-on:<event>. |
@opened, @closed |
* | suggestions visibility handler, indicates when the suggestions are opened and closed. This is called alongside shouldRenderSuggestions. |
@item-changed |
suggestionItem, index | when keying through the results, this event signals which item is highlighted before being selected. |
Browser support
For IE11 and below, some functionality may not work. For example, you will have to manually polyfill Node.prototype.contains
