filterTxt = ko.observableArray([]);
Here filterTxt is observable array which bind with input field. i.e.
HTML :
<input id="filterText" data-bind="value: SearchText, valueUpdate: 'afterkeyup' />
<div data-bind="foreach: arrayFilter ">
<p data-bind="text: Label"></p>
<p data-bind="text: Description"></p>
<p data-bind="text: Label"></p>
<p data-bind="text: Description"></p>
</div>
SCRIPT :
var arrayFilter = ko.computed(function () {
try {
var text = filterTxt.toLowerCase();
if (!text) {
return arrayCollection();
}
else {
if (arrayCollection().length > 0) {
return ko.utils.arrayFilter(arrayCollection (), function (item) {
if (item.Label.toLowerCase().indexOf(text) > -1 || item. Description.toLowerCase().indexOf(text) > -1) {
return true;
}
else {
return false;
}
});
}
}
}
catch (ex) {
//TODO: as per need.
}
});
