Jquery - Show Textbox When Checkbox Checked

Question

I have this form

Solution 1:

As your dividers are placed next to your checkboxes, you simply need to use jQuery's next() method to select the correct elements:

if ($(this).is(':checked'))
    $(this).next('div.max_tickets').show();
else
    $(this).next('div.max_tickets').hide();

Updated Codepen demo.

From the documentation (linked above), the next() method selects:

...the immediately following sibling of each element in the set of matched elements. If a selector is provided, it retrieves the next sibling only if it matches that selector.

Here we're selecting the next div.max_tickets element. However in your case just using next() with no parameters would suffice.

Solution 2:

Assuming markup will stay in same order can use next()

jQuery(document).ready(function($) {

    $('input.maxtickets_enable_cb').change(function(){
                $(this).next()[ this.checked ? 'show' : 'hide']();  
    }).change();
});

Solution 3:

Change:

if ($(this).is(':checked')) $('div.max_tickets').show();

To:

if ($(this).is(':checked')) $(this).next('div.max_tickets').show();

Solution 4:

Maybe try selecting the next element only?

change:

if ($(this).is(':checked')) $('div.max_tickets').show();

to:

if ($(this).is(':checked')) $(this).next('div.max_tickets').show();

Solution 5:

Put a div across your checkbox and text box

<form action="">
<div id="opwp_woo_tickets">
<div>
    <input type="checkbox" class="maxtickets_enable_cb" name="opwp_wootickets[tickets][0][enable]">
    <div class="max_tickets">
        <input type="text" name="opwp_wootickets[tickets][0][maxtickets]">
    </div>
</div>
<div>
    <input type="checkbox" class="maxtickets_enable_cb" name="opwp_wootickets[tickets][1][enable]">
    <div class="max_tickets">
        <input type="text" name="opwp_wootickets[tickets][1][maxtickets]">
    </div>
</div>
<div>
    <input type="checkbox" class="maxtickets_enable_cb" name="opwp_wootickets[tickets][2][enable]">
    <div class="max_tickets">
        <input type="text" name="opwp_wootickets[tickets][2][maxtickets]">
    </div>
</div>
</div>
</form>

and replace your jquery code with this one below,

jQuery(document).ready(function($) {
   $('input.maxtickets_enable_cb').change(function(){
       if ($(this).is(':checked')) $(this).parent().children('div.max_tickets').show();
       else $(this).parent().children('div.max_tickets').hide();
   }).change();
});

I have tested it and it works.
