jQuery - Filters


jQuery过滤器

Use jQuery to filter/search for specific elements.


过滤表s

Perform a case-insensitive search for items in a table:

Example

Type something in the input field to search the table for first names, last names or emails:


Firstname Lastname Email
John Doe john@example.com
Mary Moe mary@mail.com
July Dooley july@greatstuff.com
Anja Ravendale a_r@test.com

jQuery

<script>
$(document).ready(function(){
  $("#myInput").on("keyup", function() {
    var value = $(this).val().toLowerCase();
    $("#myTable tr").filter(function() {
      $(this).toggle($(this).text().toLowerCase().indexOf(value) > -1)
    });
  });
});
</script>

Example explained: We use jQuery to loop through each table rows to check if there are any text values that matches the value of the input field. The toggle() method hides the row (display:none) that does not match the search. We use the toLowerCase() DOM method to convert the text to lower case, which makes the search case insensitive (allows "john", "John", and even "JOHN" on search).


过滤器列表s

Perform a case-insensitive search for items in a list:

Example

Type something in the input field to search the list for items:


  • First item
  • Second item
  • Third item
  • Fourth
