The implementation code to make the div layer move with the mouse ie ff_javascript skills

function IsIE() {
var OsObject = "";
if (navigator.userAgent.indexOf("MSIE") > 0) {
return true;
}
}
function mouseMove(ev) {
/*ie The event mechanism is different from that of ff*/
ev = ev || window.event;
var mousePos = mouseCoords(ev);
var detailDiv = document .getElementById("detailDiv"); //The layer that will pop up
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 The boundary processing is different from ff*/
if (IsIE()) {
return { x: ev.clientX document.documentElement.scrollLeft - document.documentElement.clientLeft, y: ev.clientY document.documentElement.scrollTop - document.documentElement.clientTop }
}
else {
return { x: ev.clientX document.body.scrollLeft - document .body.clientLeft, y: ev.clientY document.body.scrollTop - document.body.clientTop }
}
}
document.onkeydown = keydown;
