How to clear all <div>s’ contents inside a parent <div>?

Question

I have a div <div id="masterdiv"> which has several child <div>s.

Example:

<div id="masterdiv">
  <div id="childdiv1" />
  <div id="childdiv2" />
  <div id="childdiv3" />
</div>

How to clear the contents of all child <div>s inside the master <div> using jQuery?

Answer 1

jQuery('#masterdiv div').html('');

Answer 2

jQuery's empty() function does just that:

$('#masterdiv').empty();

clears the master div.

$('#masterdiv div').empty();

clears all the child divs, but leaves the master intact.

Answer 3

Use jQuery's CSS selector syntax to select all div elements inside the element with id masterdiv. Then call empty() to clear the contents.

$('#masterdiv div').empty();

Using text('') or html('') will cause some string parsing to take place, which generally is a bad idea when working with the DOM. Try and use DOM manipulation methods that do not involve string representations of DOM objects wherever possible.

Answer 4

If all the divs inside that masterdiv needs to be cleared, it this.

$('#masterdiv div').html('');

else, you need to iterate on all the div children of #masterdiv, and check if the id starts with childdiv.

$('#masterdiv div').each(
    function(element){
        if(element.attr('id').substr(0, 8) == "childdiv")
        {
            element.html('');
        }
    }
 );

Answer 5

The better way is :

 $( ".masterdiv" ).empty();

Answer 6

jQuery recommend you use ".empty()",".remove()",".detach()"

if you needed delete all element in element, use this code :

$('#target_id').empty();

if you needed delete all element, Use this code:

$('#target_id').remove();

i and jQuery group not recommend for use SET FUNCTION like .html() .attr() .text() , what is that? it's IF YOU WANT TO SET ANYTHING YOU NEED

Answer 7

$("#masterdiv > *").text("")

$("#masterdiv").children().text("")

Answer 8

$("#masterdiv div").text("");

Answer 9

You can use .empty() function to clear all the child elements

 $(document).ready(function () {
  $("#button").click(function () {
   //only the content inside of the element will be deleted
   $("#masterdiv").empty();
  });
 });
