javascript - jQuery On click wont fire -



javascript - jQuery On click wont fire -

i have textbox, checkbox , span tag. when click on checkbox, should show state in span tag. when textbox updated, reinserts checkbox block. when click on checkbox now, fails update state.

i using on event handler checkbox click event, expect work.

any thought why not working expected?

class="snippet-code-js lang-js prettyprint-override">$('div[role] input[type=checkbox]').on('click', chg); $('div[role] input[type=text]').on('input', sourcechanged); function chg() { var istiki = $(this).is(":checked"); $('#upd').html(istiki); } function sourcechanged() { $('span', $(this).closest('.input-group')).html('<input type="checkbox">'); } class="snippet-code-html lang-html prettyprint-override"><script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script> <div role="tiki" class="input-group"> <input type="text" class="form-control" /> <span class="input-group-addon"><input type="checkbox" /></span> </div> <span id="upd"></span>

as you're dynamically creating new checkbox when value changes, need delegate event checkbox assigning non-dynamic ancestor:

$('div[role]').on('change', 'input[type=checkbox]', chg);

note how i've used change instead of click more appropriate checkboxes.

in below snippet i've changed $(this).is(":checked") this.checked.

class="snippet-code-js lang-js prettyprint-override">$('div[role]').on('change', 'input[type=checkbox]', chg); $('div[role] input[type=text]').on('input', sourcechanged); function chg() { var istiki = this.checked; $('#upd').html(istiki); } function sourcechanged() { $('span', $(this).closest('.input-group')).html('<input type="checkbox">'); } class="snippet-code-html lang-html prettyprint-override"><script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script> <div role="tiki" class="input-group"> <input type="text" class="form-control" /> <span class="input-group-addon"><input type="checkbox" /></span> </div> <span id="upd"></span>

note if want false should convert istiki variable string:

$('#upd').html('' + isticki);
