JavaScript-添加和删除div onclick子href

Question

In my form I have a href called Add Record which when clicked adds a new line of html elements to the form. The added line of html elements has a remove and add href. Upon clicking the remove at the end of the line, that specific line gets removed...however, when I click on the add on the child element, a new line is not getting created.

 $(document).ready(function(e) { var html = '<div><label>Category:</label><select id="childcategory"><option value="0" selected>Select Category</option><option value="CatA">Category A</option><option value="CatB">Category B</option></select><a href="#" id="remove">Remove</a><a href="#" id="childAdd">AddRecord</a></div>'; var maxRows = 20; var x = 1; //Add rows $("#add").click(function(e) { if (x <= maxRows) { $("#container").append(html); x++; } }) /*//Add rows $("#container").on('click', '#childAdd', function(e){ $(this).parent('div').add(); x++; }) })*/ //Remove rows $("#container").on('click', '#remove', function(e) { $(this).parent('div').remove(); x--; }) }) 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <form> <div id="container" class="container-fluid"> <div class="row"> <div class="col-sm-12"> <div class="main-content"> <div class="block"> <label>Category:</label> <select id="category" name="category[]" required> <option value="0" selected>Select Category</option> <option value="ToiletSoap">Toilet Soap</option> <option value="ToothPaste">ToothPaste</option> </select> <a href="#" id="add">Add record</a> </div> </div> </div> </div> </div> </form> 

Answer 1

you can use same function to add record , I hope this is your expected out put, if not please comment, i will update

 $(document).ready(function(e) { var html = '<div><label>Category:</label><select id="childcategory"><option value="0" selected>Select Category</option><option value="CatA">Category A</option><option value="CatB">Category B</option></select><a href="#" id="remove">Remove</a><a href="#" id="childAdd">AddRecord</a></div>'; var maxRows = 20; var x = 1; //Add rows $("form").on('click','#add, #childAdd', function(e) { if (x <= maxRows) { $("#container").append(html); x++; } }) //Remove rows $("#container").on('click', '#remove', function(e) { $(this).parent('div').remove(); x--; }) }) 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <form> <div id="container" class="container-fluid"> <div class="row"> <div class="col-sm-12"> <div class="main-content"> <div class="block"> <label>Category:</label> <select id="category" name="category[]" required> <option value="0" selected>Select Category</option> <option value="ToiletSoap">Toilet Soap</option> <option value="ToothPaste">ToothPaste</option> </select> <a href="#" id="add">Add record</a> </div> </div> </div> </div> </div> </form> 

Answer 2

In the code above

var html = '<div><label>Category:</label><select id="childcategory"><option value="0" selected>Select Category</option><option value="CatA">Category A</option><option value="CatB">Category B</option></select><a href="#" id="remove">Remove</a><a href="#" id="childAdd">AddRecord</a></div>';

var maxRows = 20;
var x = 1;
//Add rows
$("#add").click(function(e) {       //<---  Try using #childAdd  instead of #add or change childAdd ID of href to add.
  if (x <= maxRows) {
    $("#container").append(html);
    x++;
  }
})

Because in HTML add href, you have used id as childAdd .

Hope this helps.

Answer 3

shouldn't this be a different DIV?

$("#container").append(html);

> $("#main-content").append(html);

Answer 4

1. I would not prefer giving the same id, use classes instead of ids
2. You missed append(html) while adding rows

 $(document).ready(function(e) { var html = '<div><label>Category:</label><select id="childcategory"><option value="0" selected>Select Category</option><option value="CatA">Category A</option><option value="CatB">Category B</option></select><a href="#" class="remove">Remove</a><a href="#" class="childAdd">AddRecord</a></div>'; var maxRows = 20; var x = 1; //Add rows $("#add").click(function(e) { if (x <= maxRows) { $("#container").append(html); x++; } }) //Add rows $("#container").on('click', '.childAdd', function(e){ $(this).parent('div').append(html); console.log("child add") x++; }) //Remove rows $("#container").on('click', '.remove', function(e) { $(this).parent('div').remove(); x--; }) }) 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <form> <div id="container" class="container-fluid"> <div class="row"> <div class="col-sm-12"> <div class="main-content"> <div class="block"> <label>Category:</label> <select id="category" name="category[]" required> <option value="0" selected>Select Category</option> <option value="ToiletSoap">Toilet Soap</option> <option value="ToothPaste">ToothPaste</option> </select> <a href="#" id="add">Add record</a> </div> </div> </div> </div> </div> </form>
