i guess i was able to clear the things

i used following js

function devide(id, evt){
    alert(id);
    var divElement = document.getElementById(id);
    if(typeof(divElement) != "undefined" && divElement!=null){
        captureMousePosition(evt);
        if(splitVertical==1)
            verticalSplit(divElement);
        else
            horizontalSplit(divElement);
    }
}

function verticalSplit(divElement){
    divElement.style.border = "0px red dashed";
//  divElement.removeAttribute("onclick");
    var width = ((divElement.offsetWidth-(xMousePos-LEFT_MARGIN))/divElement.offsetWidth)*100;
    var newDiv1 = document.createElement("div");
    newDiv1.setAttribute("id", divElement.id+"0");
//  newDiv1.onclick = "devide('"+divElement.id+"0', event);";
    newDiv1.style.width = (100-width)+"%";
    newDiv1.style.height = "100%";
    newDiv1.style.float = "left";
    newDiv1.style.border = "1px red dashed";
    newDiv1.style.zIndex = divElement.style.zIndex+1;
    var newDiv2 = document.createElement("div");
    newDiv2.setAttribute("id", divElement.id+"1");
    newDiv2.style.width = width+"%";
    newDiv2.style.height = "100%";
    newDiv2.style.float = "left";
    newDiv2.style.border = "1px red dashed";
    newDiv2.style.zIndex = divElement.style.zIndex+1;
    divElement.appendChild(newDiv1);
    divElement.appendChild(newDiv2);
    newDiv1.addEventListener("click",devide(divElement.id+"0", event),true);
    newDiv2.addEventListener("click",devide(divElement.id+"1", event),true);
}

but this is recursively calling devide function for the first encountered element say mainDiv0,mainDiv00,mainDiv000…. and so on

please help me with this

Answer 1

The situation you are describing is called event bubbling.

The W3C model says you can call .stopPropagation() on the event. IE might need window.event.cancelBubble

To do unobtrusive javascript with your code try:

HTML

<div id="mainDiv"></div>

JS

function devide(evt){
    var divElement = document.getElementById(this.id);// this.id !
    if(typeof(divElement) != "undefined" && divElement!=null){
        captureMousePosition(evt);
        if(splitVertical==1)
            verticalSplit(divElement);
        else
            horizontalSplit(divElement);
    }
}

document.getElementById('mainDiv').onclick=devide; // notice it's just the function name
