.keyinselect - JavaScript

.keyinselect is a JavaScript function that provides an alternative way to select options from a drop-down list by allowing users to enter the value directly into the option field.

Syntax

.keyinselect(selectElement)

This function takes in a selectElement parameter, which is the reference to the select element that you want to apply the function to.

Usage

To use .keyinselect, you need to include the keyinselect.js file in your HTML document, and then call the function on your select element.

<!-- Include keyinselect.js -->
<script src="keyinselect.js"></script>

<!-- Apply .keyinselect to the select element -->
<select id="selectBox">
  <option value="apple">Apple</option>
  <option value="banana">Banana</option>
  <option value="cherry">Cherry</option>
</select>

<script>
  .keyinselect(document.getElementById("selectBox"));
</script>

With .keyinselect applied, users can type any value directly into the select element, and the function will automatically select the option that matches the value.

Additional notes

• .keyinselect can only be applied to select elements that do not allow multiple selections.
• .keyinselect will treat the option values as case-insensitive.
