jQuery how to append data in loop only one time

Related searches

I work with loops and I add data in to table, from buttons. So each time it creates 5 cells for me, but I need to append data only one time after button click.

Code:

$('.next').on('click', function () {
    $('.changeoverTable').show();
    var arrNumber = new Array();
    $('input[type=text]').each(function (i) {
        arrNumber.push($(this).val());
            $(".changeoverTable > tbody").append('<tr><td>Data</td><td>' + arrNumber[i] + '</td></tr>'); 
    })
});
body {
  background: #f5f5f5;
}

.hide {
    display: none;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.4.0/jquery.min.js"></script>
<input type="text" placeholder="Enter number of data"><button class="next">ok</button>
<input type="text" placeholder="Enter number of layers"><button class="next">ok</button>
<input type="text" placeholder="Enter number of nest"><button class="next">ok</button>
<input type="text" placeholder="Enter number of layers"><button class="next">ok</button>
   <table class="changeoverTable hide">
                <thead>
                    <tr>
                        <th colspan="3">Table</th>
                    </tr>
                </thead>
                <tbody>
                </tbody>
            </table>

Just do a if condition if(arrNumber[i]){ check if value exists.

$('.next').on('click', function () {
    $('.changeoverTable').show();
    var arrNumber = new Array();
    $(".changeoverTable > tbody").html('');
    $('input[type=text]').each(function (i) {
    
        arrNumber.push($(this).val());
        if(arrNumber[i]){
            $(".changeoverTable > tbody").append('<tr><td>Data</td><td>' + arrNumber[i] + '</td></tr>'); 
            }
    })
});
body {
  background: #f5f5f5;
}

.hide {
    display: none;
}

                    </tr>
                </thead>
                <tbody>
                </tbody>
            </table>

Append Outside of Loops, at a time. This is a common problem when appending elements within a loop. After the loop, just append the fragment to the DOM element. I have one jquery method and i used call that method on click of a button . So in that code i have one line " $("#loadingMessage").css('padding-top','6%');" i need this line execute only once when we call that method first time,later that i gone this line . So please help me to find one way. the entire method script is below

You can try with this:

$('.next').on('click', function() {
  $('.changeoverTable').show();
  $('.changeoverTable tbody tr').remove();
  $('input[type=text]').each(function(i) {
    if ($(this).val()) $(".changeoverTable > tbody").append('<tr><td>Data</td><td>' + $(this).val() + '</td></tr>');
  })
});

Please notice that I've added $('.changeoverTable tbody tr').remove(); to remove the old records in the table.

Also there is no reason to use an Array for this.

Demo

$('.next').on('click', function() {
  $('.changeoverTable').show();
  $('.changeoverTable tbody tr').remove();
  $('input[type=text]').each(function(i) {
    if ($(this).val()) $(".changeoverTable > tbody").append('<tr><td>Data</td><td>' + $(this).val() + '</td></tr>');
  })
});
body {
  background: #f5f5f5;
}

.hide {
  display: none;
}

jQuery append html x-amount of times - JavaScript, For example, I might want to append a paragraph 3 times to the same div. I'll probably have to include a loop somewhere? Just build up a string, then replace the HTML of the content div with the newly created string, like so: with each select element, you might consider storing it as a data attribute on each element. Data to be passed to the handler in event.data when an event occurs. The .one() method is identical to .on() , except that the handler for a given element and event type is unbound after its first invocation.

Try this:

$('.next').on('click', function () {
    $('.changeoverTable').show();
    var arrNumber = new Array();
    var check=0;
    $('input[type=text]').each(function (i) {
if(check==0){
        arrNumber.push($(this).val());
            $(".changeoverTable > tbody").append('<tr><td>Data</td><td>' + 
arrNumber[i] + '</td></tr>');
}
 check=1; 
    })
});

Loop through Elements, Arrays and Objects using jQuery .each , The jQuery .each() function is an alternative to JavaScript for loop. The .each() function is not only efficient, but has many interesting properties, using which, objects, arrays and simultaneously fetch and manipulate data, properties etc. I wish to loop through each <span>, extract the characters and append it to a <p>. Append data dynamically by for loop using jQuery in PHP. For loop using jQuery in PHP: Dynamically add records in a table to get results from MySQL table without page reload.

A couple questions about using .append() and .remove , The above creates a jQuery object that is a node list of all P elements (and their DOM trees) and removes them. Not very One of the lessons has us remove only the fourth LI in an OL. For that we The above is also an example of a, one- off procedure. Let's write a silly loop that gives different colors to all P elements. Understanding the jQuery .each() method and its uses: Here in this article will learn how and where we can use jquery $.each() method with live example.

  • @qunz666 When I click on an OK button I get 4 rows
  • Please take the time to describe what the issues are and why this solution helps. Remember, we're here to educate people, not just write code for them.
