I am looking to modify the provided fiddle so that instead of having computedPageLinks update with each key press in the search input, it updates only when a button is clicked and does not change when the search input loses focus. Can anyone assist with this modification?
If you want to ensure that your search results update only when triggered by a click event, rather than every time the query value changes, you can modify your approach slightly.
One way to achieve this is by creating a separate observable array called "results" and populating it with the search results upon clicking a button. Here's how you can implement this:
Start by defining the "results" array:
self.results = ko.observableArray([]);
Next, create a search function that updates the "results" array based on the query input:
self.search = function() {
if (!self.query()) {
self.results([]);
return;
}
self.results(ko.utils.arrayFilter(self.pageLinks(), function(item) {
return item.title.toLowerCase().indexOf(self.query().toLowerCase()) >= 0;
}) || []);
};
Once you have set up the "results" array and search function, adjust your binding to utilize the "results" array instead of a computed observable:
<tbody data-bind="foreach: results">
To complete the setup, remove the valueUpdate setting from your <input> element and include a button that triggers the search function:
<input placeholder="Search…" type="search" name="q" data-bind="value: query" autocomplete="off" />
<button type="button" data-bind="click: search">Go</button>
