Working on an HTML autocomplete box example, I have it functioning well. I am now seeking guidance on setting a height for the autocomplete items to prevent them from becoming too lengthy when there are numerous items. I would like to establish a max-height so they can be scrolled through.
To limit the height of the autocomplete feature to a maximum of 100px in your example, you simply need to include max-height: 100px and overflow-y: scroll within the style for the .autocomplete-items class.
Here is a demonstration:
// JavaScript code for autocomplete functionality
function autocomplete(inp, arr) {
// Function logic goes here...
}
// Array of country names for autocomplete suggestions
var countries = ["Afghanistan", "Albania", ... ];
// Initialize autocomplete function on input element with id "myInput"
autocomplete(document.getElementById("myInput"), countries);/* CSS styles for autocomplete feature */
.autocomplete {
/* Styles for container go here... */
}
input[type=submit] {
/* Button styles */
}
.autocomplete-items {
/* Styles for autocomplete dropdown */
max-height: 100px;
overflow-y: scroll;
}
.autocomplete-active {
/* Active item styles */
}<h2>Autocomplete</h2>
<p>Start typing:</p>
<form autocomplete="off" action="/action_page.php">
<div class="autocomplete" style="width:300px;">
<input id="myInput" type="text" name="myCountry" placeholder="Country">
</div>
<input type="submit">
</form>Is there a way to set the input field to have a default value and then change it, or disable it with a different value? $("#tax").value(19).prop("disabled",false); $("#tax").value(0).prop("disabled",true); <script src="https://ajax.googleapis.com/aj ...
