Conflicting unique IDs between checkbox and styling script causing issues

Here is the style I am aiming for: http://jsfiddle.net/f07t3qkn/

The issue I am facing is that my current checkboxes all have the same id, which is 'level'. There is a script below that relies on this specific id to execute certain tasks, so changing the ids to be unique is not an option.

However, in the desired checkbox style, each checkbox should have a unique id. This poses a problem as it hinders the functionality of the script when trying to achieve the desired styling.

So, my question is how can I modify the script to accommodate unique ids for the checkboxes for styling purposes while still performing the necessary functions?

Alternatively, is there a way for the script to identify checkboxes based on ids starting with the word 'level', such as 'level_1', 'level_2', etc., rather than relying on a fixed id like 'level'? I have tried various approaches without success and any specific code examples would be greatly appreciated. Thank you in advance.

Below is the HTML code for the current checkboxes:

<ul class="box small-block-grid-1 medium-block-grid-2 large-block-grid-2">
    <li><input type="checkbox" name="level[Primary]" id="level" class="level" value="1"><label>Primary</label></li>
    <li><input type="checkbox" name="level[Upper Secondary]" id="level" class="level" value="3"><label>Upper Secondary</label></li>
    <li><input type="checkbox" name="level[University]" id="level" class="level" value="5"><label>University</label></li>
    <li><input type="checkbox" name="level[Lower Secondary]" id="level" class="level" value="2"><label>Lower Secondary</label></li>
    <li><input type="checkbox" name="level[Pre University]" id="level" class="level" value="4"><label>Pre University</label></li>
    <li><input type="checkbox" name="level[Other]" id="level" class="level" value="6"><label>Other</label></li>                 
</ul>

Script utilizing the id to perform other tasks:

<script>
$("#slider1").change(function() {
  var value = $(this).val();
  sendtobox(value, $("input[type=checkbox]#level").val());
});

$("input[type=checkbox]#level").change(function() {  
  var selectedval = $(this).val();
  if($(this).is(":checked")) {
    var selectedtext = $(this).next().text();
    sendtobox(selectedval, $("#slider1").val());
  }
  else {
    $("th."+selectedval).remove(); // controls removing from boxA

  }
});
</script>

Answer №1

It's important to remember that id attributes need to be unique.

However, you can still target elements with similar classes or id values in CSS (and jQuery) using attribute selectors as described here.

If you change your id values to something like level1, level2, level3, etc., you can then select all matching elements in CSS with:

input[type=checkbox][id^=level]{

}

Or in jQuery, you can use:

$("input[type=checkbox][id^=level]")

[attr^=value] Represents an element with an attribute name of attr and a value that is prefixed by "value".

Keep in mind that expression-based selectors may not be as efficient as more common selectors. It's usually recommended to assign the same class to items that should share styling, and then style them accordingly by selecting this class.

Considering that the relevant checkboxes all have the class level, update

input[type=checkbox]#level

In your jQuery code to:

input[type=checkbox].level

This approach should eliminate the need for duplicate id values.

Answer №2

If you're looking to tackle your issue, consider these options:

  1. Within your code, opt for using a class when referencing multiple elements instead of an ID since IDs should be unique to each element.

  2. You could assign additional IDs to each checkbox. For example: id="level first_checkbox"

There may be other methods available, but I believe these suggestions will effectively address your dilemma.
