I create a div and its css id like this.

<div id="r1" class="ansbox"></div>
<div id="r2" class="ansbox"></div>
<div id="r3" class="ansbox"></div>
<div id="r4" class="ansbox"></div>
<div id="r5" class="ansbox"></div>
<div id="r6" class="ansbox"></div>
<div id="r7" class="ansbox"></div>
<div id="r8" class="ansbox"></div>
<div id="r9" class="ansbox"></div>
<div id="r10" class="ansbox"></div>

is there a way to create this div using looping statement. Anyone help me..

I would recommend using some javascript (without jquery) for performance:

var toAdd = document.createDocumentFragment();
for(var i=0; i < 11; i++){
   var newDiv = document.createElement('div');
   newDiv.id = 'r'+i;
   newDiv.className = 'ansbox';
   toAdd.appendChild(newDiv);
}

document.appendChild(toAdd);

This way you only make one append(), only 1 reflow, and you don't need jQuery.

To append it to a jQuery selector:

$('sel').append(toAdd);

Or a dom element:

document.getElementById('sel').appendChild(toAdd);

  • You can make only one `append` with jQuery as well – Esailija Jul 09 '12 at 15:51

    I agree that using pure JS boosts performance, but creating a list of nodes the way you're suggesting _is_ in essence slower than stringing the html together in most cases. – Elias Van Ootegem Jul 09 '12 at 15:53
  • I totally agree; I like making nodes because it lets you play with the DOM elements before you append them... but it's totally dependent on the use-case – bokonic Jul 09 '12 at 15:53
  • For those curious, [this approach](https://stackoverflow.com/a/33312039/943773) seems to be a good way to of just stringing the html together, as mentioned here in the comments. – ryanjdillon Jan 12 '18 at 13:05
  • I get error: HierarchyRequestError: The operation would yield an incorrect node tree. All I did was copy all the code until the line (this way you only make one append...) Did I need to use the code after the line as well? – Nakul Tiruviluamala Nov 13 '19 at 20:18

Suppose you have following div where you will insert new divs:

<div id="target">
   <!-- all divs will append here -->
</div>

jQuery:

for(var i =1; i<= 10; i++){
  $('#target').append($('<div/>', { id: 'r' + i, 'class' : 'ansbox'}))
}

or

for(var i =1; i<= 10; i++){
  $('#target').append('<div id="r'+ i +'" class="ansbox"></div>')
}

I will go for first approach.

Here's one option:

for(var i = 0; i <=10; i++) {
   $('<div id="r'+i+'" class="ansbox"></div>').appendTo("target");
}

<div class="ibox-content" id="location-div">                        
    <div class="row">
        <div class="col-sm-12">
            <button id="addlocation" type="button" class="btn btn-w-m btn-primary pull-right">Add new location</button>
        </div>
    </div>
    <div class="row" style="margin-top:10px;">
        <div class="col-sm-2">
            <label class="form-label">Location <span ><input type="text" readonly id="locval" style="width:20px;border:0px;" value="1"></span></label>
        </div>
        <div class="col-sm-10">
            <input type="text" name="" class="form-control "> 
        </div>
    </div>

</div>

Here I want to add a dynamic row by adding 1 to each new entry this will solve your problem

<script>
    $(document).ready(function(){
        var inno = document.getElementById("locval").value;
        for(var start = 1; inno >= start; start+=1)
        {
            start;
        }
    $("#addlocation").click(function(){
        $("#location-div").append('<div class="row" style="margin-top:10px;"><div class="col-sm-2"><label class="form-label">Location <span ><input type="text" readonly id="locval" style="width:20px;border:0px" value="'+start+++'"></span> </label></div><div class="col-sm-10"><input type="text" name="" class="form-control "></div></div>');
      });
    });
</script>

I would recommend using simple javascript loop (without jquery) for performance:







let container = document.getElementById('container');
    for (let i = 0; i <= 10; i++) {
        let element = document.createElement('div');
        container.appendChild(element);
    };
console.log(container);

    for (let i = 0; i <= 10; i++) {
        let element = document.createElement('div');
        container.appendChild(element);
    };
