jquery filtering checkbox list by input box

Question

I have a long checkbox list (with same name). I want create a filtering system based on input in a text box. I mean, when I write "ter" in my text box, I want to show only those chechboxes which values matches %ter% (means have the phrase "ter" anywhere). What is the best way to achieve that using jquery? My apologies as I am very new to jquery.

<input type="checkbox" name="chk" id="chk1" value="casual">casual
<input type="checkbox" name="chk" id="chk2" value="intermediate">intermediate
<input type="checkbox" name="chk" id="chk3" value="hunter">hunter
<input type="checkbox" name="chk" id="chk4" value="forest">forest
<input type="checkbox" name="chk" id="chk5" value="term">extreme
<input type="checkbox" name="chk" id="chk6" value="river">river
<input type="checkbox" name="chk" id="chk7" value="beach">beach
<input type="text" id="chkfilter">

So, whenever I write "ter" in the text box, checkbox 2,3 and 5 should be visible, others should be hidden/gone. How to do that? Using div for each individual item? Also, how to search using jquery to match %ter%

Answer 1

When you type something in the textbox, check the checkboxes to see it that string exists in the value with indexOf, and set the display property based on that (I used block, but inline is probably correct for checkboxes):

$('#chkfilter').on('keyup', function() {
    var query = this.value;

    $('[id^="chk"]').each(function(i, elem) {
          if (elem.value.indexOf(query) != -1) {
              elem.style.display = 'block';
          }else{
              elem.style.display = 'none';
          }
    });
});

The text after the checkbox is not part of the checkbox and will not be hidden, to do that you should probably wrap it in a label and do something like this JSBIN ??
