Javascript tooltip positioning issue

I would like to create a javascript popup using following script.

var xOffset = 30;
var yOffset = -5;

function showPopup (targetObjectId, eventObj) {
    var newXCoordinate = (eventObj.pageX)?eventObj.pageX + xOffset:eventObj.x + xOffset + ((document.body.scrollLeft)?document.body.scrollLeft:0);
    var newYCoordinate = (eventObj.pageY)?eventObj.pageY + yOffset:eventObj.y开发者_开发百科 + yOffset + ((document.body.scrollTop)?document.body.scrollTop:0);
    moveObject(targetObjectId, newXCoordinate, newYCoordinate);

    -----etc
}



function moveObject(objectId, newXCoordinate, newYCoordinate) {
    // get a reference to the cross-browser style object and make sure the object exists
    var styleObject = getStyleObject(objectId);
    if(styleObject) {

//      newXCoordinate = newXCoordinate-8;
//      newYCoordinate = newYCoordinate-300;

        styleObject.left = newXCoordinate;
        styleObject.top = newYCoordinate;
        return true;
    } else {
        // we couldn't find the object, so we can't very well move it
        return false;
    }
} // moveObject

Popup will show successfully but, its positioning becomes an issue. Popup not getting dynamic position according to cursor move. Anybody can please help to change the above script to show popup position according to cursor position. ie, normally popup attach to bottom of element; if there is not enough space at bottom popup should attach top

Thanks

I think this is what you need:

<li id="list-item" onclick="return !showPopup('product_deatils_2', event);">
    <a href="javascript:;">Product2</a>
    <div onclick="event.cancelBubble = true;" class="popup" id="product_deatils_2"><a href="javascript:;" onclick="hideCurrentPopup(); return false;" title="close" class="popupLink">[x]</a> Popup Text  
    </div>
</li>

and in your JS use something like this:

$("#list-item").click(function (e) {
    $("#product_deatils_2").css("margin-left",e.offsetX);
    $("#product_deatils_2").css("margin-top",e.offsetY); 
});

Let me know if it helps :)

I just modified the functions like

function showPopup(elementN, event){
    $("#"+elementN).css({
        "display":"block",
        "top":event.pageY+"px" ,
        "left":event.pageX+"px"    
    })
}
function hideCurrentPopup(ele){
    $(ele).parent().hide();
}

if you dont use jquery then also it can be simply implemented in pure js.
