表单字段值未正确传递到JSON对象中

Question

This is my JSFiddle : https://jsfiddle.net/inchrvndr/7pwh9p8g/

The bordered form elements get cloned on click of "+" button. 

The values of all the cloned form elements are getting passed into JSON except for the parent whose clone is being made.

On clicking "Save" button, you can see the alert for JSON object of all form field values except for the first bordered div.

Why is this so? Please help. Thanks :)

Answer 1

try this..

UPDATE:

you have duplicate elements, like this one: id="op" there can be only one ID unique on page.. I suggest that you drop id's or generate them

 $( document ).ready(function() { $('#deleteRow').closest('.form-group').hide(); $('#addRow').on('click', function (e) { var len = $('.child-border').length; $('.parent-border-repeat').clone().find(':input').each(function (idx, ele) { ele.name = ele.name + len; ele.id = ele.id + len; ele.value = ''; }).end().find('.form-group').toggle(true).end() .toggleClass('parent-border-repeat child-border').hide() .appendTo('#container').slideDown('slow'); }); $('button.btn:contains("Save")').on('click', function (e) { var jsonData = $('form.form-horizontal') .find(':input:not(button)').get() .reduce(function (acc, ele) { acc[ele.id] = ele.value; return acc; }, {}); // console.log(jsonData); alert(JSON.stringify(jsonData, null, 4)); }); $('#container').on('click', '[id^=deleteRow]', function(e) { var jsonData = $(this).closest('.child-border, .parent-border-repeat') .find(':input:not(button)').get() .reduce(function (acc, ele) { acc[ele.name || ele.id] = ele.value; return acc; }, {}); $(this).closest('.child-border, .parent-border-repeat').remove(); console.log(jsonData); }); }); 

 .navbar-nav li { margin-top: 8px; margin-bottom: 8px; } .tabs-container { margin-top: 100px; margin-bottom: 75px; } .parent-border-repeat{ display: none; } .parent-border, .child-border { border: 1px solid #CCC; border-radius: 4px; padding: 15px; margin-bottom: 15px; } .btn-circle.btn-lg { width: 50px; height: 50px; padding: 10px 16px; font-size: 18px; line-height: 1.33; border-radius: 25px; }

Answer 2

I have solved this issue.

Here is the answered fiddle : AnswerFiddle

I added the Join Operator into the same "to-be-cloned" div and hid its div before cloning.

It becomes visible after cloning, that is, after clicking on, "+" button. Now, all of the before clone and after cloned form fields' values are getting passed into the JSON.
