Adding onclick event to dynamically created javascript element

Question

I dynamically add labels to my table when the user selects items with a list, but I also want these dynamically added labels to be erased when the user clicks on them, here is my javascript function:

    function OnSelectedIndexChange()

{
    if (document.getElementById('cmbDestinationUser').selectedIndex != 0) {
        var spanTag = document.createElement("span");
        spanTag.id = "span1";
        var e = document.getElementById("cmbDestinationUser");
        var strUser = e.options[e.selectedIndex].text;
        spanTag.innerHTML = strUser;
        var TR = document.createElement('tr');
        var TD = document.createElement('td');
        TD.appendChild(spanTag);
        TR.appendChild(TD);
        document.getElementById('tblReceivers').appendChild(TR);
    }
    document.getElementById('cmbDestinationUser').selectedIndex = 0;
}

Should I add onclick for spantag? How can i do this? should i create another function to erase or i can define the delete operation in this function thanks

Answer 1

Yes, add onclick to span:

spanTag.onclick = function() {
    this.innerHTML = '';
};

It just clears the contents span. I was not sure what you mean by erasure.

span, :

spanTag.onclick = function() {
    this.parentNode.removeChild( this );
};

, :

spanTag.onclick = function() {
    var el = this;
    while( (el = el.parentNode) && el.nodeName.toLowerCase() !== 'tr' );

    if( el )
        el.parentNode.removeChild( el );
};

, :

spanTag.onclick = function() {
    var el = this.parentNode;
    while( el ) {
       if( el.nodeName.toLowerCase() === 'tr' ) {
           el.parentNode.removeChild( el );
           break;
       }
       el = el.parentNode;
    } 
};

node.

table.onclick = function (e) {
    var target = e.target || window.event.srcElement;

    while (target.nodeName !== 'TR') {
        target = target.parentNode;
    }
    target.parentNode.reamoveChild(target);
}
