我有一个拖放div,一切正常,使用:
if (document.getElementById){
(function(){
var n = 500;
var dragok = false;
var y,x,d,dy,dx;
function move(e){
if (!e) e = window.event;
if (dragok){
d.style.left = dx + e.clientX - x + "px";
d.style.top = dy + e.clientY - y + "px";
return false;
}
}
function down(e){
if (!e) e = window.event;
var temp = (typeof e.target != "undefined")?e.target:e.srcElement;
if (temp.tagName != "HTML"|"BODY" && temp.className != "dragclass"){
temp = (typeof temp.parentNode != "undefined")?temp.parentNode:temp.parentElement;
}
if (temp.className == "dragclass"){
if (window.opera){
document.getElementById("Q").focus();
}
dragok = true;
temp.style.zIndex = n++;
d = temp;
dx = parseInt(temp.style.left+0);
dy = parseInt(temp.style.top+0);
x = e.clientX;
y = e.clientY;
document.onmousemove = move;
return false;
}
}
function up(){
dragok = false;
document.onmousemove = null;
}
document.onmousedown = down;
document.onmouseup = up;
})();
}
如何添加两个单选按钮: 当检查标记为中心的单选按钮时,div将居中。
当我点击标有botton-right的单选按钮时,div移动到右下角。 ?
有什么办法可以在新功能中重复使用上述功能吗? 感谢
