How to prevent triggering mouseleave after mouseup?

Question

In my Javascript app I am having issues with event bubbling, namely I would like not to trigger mouseleave after mouse up on an element (have implemented dragging behavior therefore it moves and mouse leaves it).

How can I do that ?

EDIT

I am using d3.js to capture event in the following way :

d3.selectAll("circle")
        .on("mouseover", function(d,i){
        ...
        }
        .on("mouseup", function(d,i){
        ...
        }
        .on("mouseleave", function(d,i){
        ...
        }

I have solved it in similar way to user1671639's adivice with boolean check :

var been_in_mouseup = false;

.on("mousedown", function(d){
    ...
    been_in_mouseup = false;
})
.on("mouseup", function(d,i){
    ...
    been_in_mouseup = true;
})
.on("mouseleave", function(d, i){
    ...
    if(false == been_in_mouseup )
    {
    ...
    }
})

EDIT

Is there any more elegant way to do this ?
