Delaying Keyup Handler Execution
Delaying the execution of the .keyup() handler until the user pauses typing for a specified duration can enhance the responsiveness of your application. In your case, you aim to prevent excessive AJAX searches during rapid keystrokes by implementing a delay of 200 milliseconds.
The Solution: Utilizing a Custom Function
To achieve this, consider employing a custom delay function that schedules the execution of your handler after a specified timeout. You can define a function named delay() as follows:
function delay(callback, ms) { var timer = 0; return function() { var context = this, args = arguments; clearTimeout(timer); timer = setTimeout(function () { callback.apply(context, args); }, ms || 0); }; }
Implementing the Delay in Your Search Field
To implement the delay in your search field, use the delay() function as seen in this example:
$('#input').keyup(delay(function (e) { // Your AJAX search code here }, 200));
In this code, the .keyup() event handler is configured to execute the AJAX search logic after a 200-millisecond delay. When the user types within that 200-millisecond window, the AJAX search will be deferred until they pause typing.
