哪个年代的js啊？
document.writeln 太多看着头痛document.writeln("if (document.all) {");
document.writeln("object1.style.pixelLeft += x;");
document.writeln("object1.style.pixelTop  += y;}");
document.writeln("else");
document.writeln("if (document.layers) {");
document.writeln("document.object1.left += x;");
document.writeln("document.object1.top  += y;");
document.writeln("}};;")===》
document.writeln("var obj = document.GetElementById('object1');obj.style.left = parseInt(obj.style.left)+x+'px';obj.style.top = parseInt(obj.style.top)+y+'px';");
这样才兼容多浏览器其它地方，自己对着慢慢改
