Answer 1

To remove all the child of div with id P1 you may simply do this :

 document.querySelector("#P1").innerHTML = ""; //or use this //document.getElementById("P1").innerHTML = ""; //or a jQuery solution like this // $('#P1').html(""); 

 <div class="" style="" id="P1"> <div class=" child1" style="" id="C1"> <Input>Val</Input> </div> <div class=" child2" style="" id="C2"> <Input>Val2</Input> </div> </div> 

Answer 2

removeChild method removes a specific child node.If need to remove all the child ,put it in a while loop

firstChild returns the first nested element. On successful removal, the next child will be the first child,so as long as firstChild is there, it will execute

 var prtElement = document.getElementById('P1'); while (prtElement.firstChild) { prtElement.removeChild(prtElement.firstChild); } 

 <div class="Parent" style="" id="P1"> <div class=" child1" style="" id="C1"> <Input>Val</Input> </div> <div class=" child2" style="" id="C2"> <Input>Val2</Input> </div> </div>

I would recommend using jQuery:

$(document).ready(function(){
/* or whatever else function you want */
$("#parent").children().remove();
});
