html array to list

In HTML, arrays are often used to store and display data. However, displaying the array directly will bring a bad user experience. Therefore, we need to convert the HTML array into a more user-friendly list.

The process of converting HTML arrays into lists can be achieved using JavaScript and jQuery. The following will introduce in detail the implementation method of converting HTML arrays into lists.

1. Define HTML array

First, we need to define an HTML array to store data. The following is a simple HTML array example:

<ul id="array">
  <li>苹果</li>
  <li>香蕉</li>
  <li>橙子</li>
  <li>西瓜</li>
</ul>

This array contains 4 elements, namely apples, bananas, oranges and watermelons.

2. Use jQuery selector to select array elements

Next, we need to use jQuery selector to select array elements. For the above HTML array, we can use the following code:

var arrayElements = $('#array li');

This line of code will select all li elements and store them in the arrayElements variable.

3. Traverse the array elements and convert them into a list

Next, we need to traverse the array elements and convert them into a list. We can do it using the following code:

var listElements = $('<ul>');

arrayElements.each(function() {
  var listItem = $('<li>').append($(this).text());
  listElements.append(listItem);
});

First, we create an empty list element. Then, we use the each() method to traverse the selected li elements. In the loop, we create a new list item for each li element and add its text content to the list item. Finally, we add the list items to the list element.

4. Replace the original array

Finally, we need to replace the original HTML array with the list we just created. We can achieve this using the following code:

$('#array').replaceWith(listElements);

This code will select the original HTML array and replace it with the list element we just created.

The complete code is as follows:

var arrayElements = $('#array li');
var listElements = $('<ul>');

arrayElements.each(function() {
  var listItem = $('<li>').append($(this).text());
  listElements.append(listItem);
});

$('#array').replaceWith(listElements);

In this way, we have successfully converted the HTML array into a friendly list and presented it to the user.
