var OsObject = "";

return true;

}

}

function mouseMove(ev) {

/*ie 与ff的event 机制不同*/

var mousePos = mouseCoords(ev);

var detailDiv = document.getElementById("detailDiv"); //将要弹出的层

detailDiv.style.left = (mousePos.x + 10) + "px";

detailDiv.style.top = (mousePos.y + 18) + "px";

}

function mouseCoords(ev) {

if (ev.pageX || ev.pageY) {

return {

x: ev.pageX,

y: ev.pageY

};

}

/*ie 与 ff的边界 处理不同*/

if (IsIE()) {

}

else {
