Can a <select> menu be written and utilized in multiple locations on a webpage?
For instance:
<select id="dm">
<option value="">Select Quantity</option>
<option value="less ">50 - 60</option>
<option value="medium ">61 - 70</option>
<option value="large ">71 - 80</option>
<option value="xl ">Above 80</option>
</select>
What is the method for using this menu multiple times on the same webpage?
To implement the <select> with jQuery, give it a specific class and then utilize the clone() function.
<select class="categoryClass" id="dropMenu">
<option value="">Select Category</option>
<option value="movies">Movies</option>
<option value="books">Books</option>
<option value="games">Games</option>
</select>
<div id="anotherDiv"><!-- Place the dropdown here as well --></div>
$( ".categoryClass" ).clone().appendTo( "#anotherDiv" );
Preserve the original content within a placeholder script block as a reference (text/template is not recognized and will be disregarded).
<script id="dm" type="text/template">
<select>
<option value="">Select Quantity</option>
<option value="less ">50 - 60</option>
<option value="medium ">61 - 70</option>
<option value="large ">71 - 80</option>
<option value="xl ">Above 80</option>
</select>
</script>
Duplicate by executing:
var copy = $('#dm').html();
something.append(copy);
This prevents encountering issues with unique identifiers (since the select element has no ID). Moreover, it enhances readability and ease of maintenance.
Furthermore, if you intend to include this in a form, ensure that the select element is assigned a name:
var $copy = $($('#dm').html()).attr('name', newMenuName);
something.append(copy);
note: The additional $() method is used to convert the string into a DOM element before adding the attribute.
If you're hesitant about using a full templating engine like Handlebar or similar, consider a simpler solution by storing the HTML code in a variable and inserting it when needed. The downside to this approach is potential complexity and maintenance issues within the HTML code itself. Here's an example utilizing jQuery:
JS:
var myDropDown = 'your html code goes here'
$("#myDropDown").html(myDropDown);
HTML:
<div id="myDropDown"></div>
