Examples
Slider example for price using the results component Store, through the linkTo method:
<div id="refinement-lists"></div>
<div id="results"></div>
<script>
var results = sdk.component('results', '#results');
// Values used by the custom filter that will be modified
var templateValues = {
label: 'Maximum Price',
step: 1,
min: 10,
max: 100,
value: 10,
}
// Create custom filter with the template, the previous values and the header text
const priceFilter = sdk.filterComponent('custom', {
templates: `
<label>{{ label }}:
<input
style="width: 75%"
step="{{ step }}"
min="{{ min }}"
max="{{ max }}"
type="range"
value="{{ value }}"
>
</label>
<span style="width: 25%" id="price-filter-value">{{ value }}</span>`,
templateValues
});
var refinementLists = sdk.component('refinement-lists', '#refinement-lists', {
refinements: [
{ component: priceFilter, headerText: 'Price' }
]
});
results.linkTo(refinementLists);
// Create the facet that the custom filter will filter
results.searchStore.addFacet("PRICE")
// Create event listener for when the slider changes value
priceFilter.setListener('input', 'change', function (id, el) {
// Remove and add the PRICE attribute refinement with filter "lte" (Less or equal than)
results.searchStore.removeFacetRefinement("PRICE", templateValues.value, "lte");
results.searchStore.addFacetRefinement("PRICE", el.value, "lte")
// Update the current value in the template so that it updates
templateValues.value = el.value;
// Notify the price filter to update the template
priceFilter.setTemplateValues(templateValues);
});
</script>
