Hello

I have this function :

function removeelement(element){
      jQuery.("#WishList").remove("#"+element);
}

I need that variable 'elemnt' to be interpreted as name of a div

Thanks

Thanks gurvinder372.

I have modified my function:

function removeelement(element){
      //jQuery.("#WishList").remove("\"#"+element+"\"");
      alert(element);
      var d = document.getElementById('WishList');
      var olddiv = document.getElementById(element);
      d.removeChild(olddiv);
}

Now I have an error : var olddiv = document.getElementById(element); olddiv is null.
The element div is added dynamically

Any ideea?

javascript : http://jsfiddle.net/mVHjx/

function removeelement(element){
      var divs = document.getElementsByTagName("div");
    for(var i=0;i<divs.length;i++) {
        var div = divs[i];
        if( div.getAttribute("name") == element ) {
            div.parentNode.removeChild(div);            
        }
    }
}

alert("before");
removeelement("_e");
alert("after");

Open in new window


jQuery : http://jsfiddle.net/c8vKC/2/

function removeelement(element){
    $("div[name='" + element + "']").remove();
}

alert("before");
removeelement("_e");
alert("after");

Definition and Usage

The name attribute specifies a name for an input element.

The name attribute is used to identify form data after it has been submitted to the server, or to reference form data using JavaScript on the client side.

Note: Only form elements with a name attribute will have their values passed when submitting a form.

Thank you leakim971

I used your function in this way :
function removeelement(element){
    $("div[id='" + element + "']").remove();
}

When i said 'name' I meant 'ID'. My mistake.

Thanks again.
