我想停止使用setTimeout运行的函数,并且不显示随鼠标显示的图像。我想用按钮点击来做,那是怎么回事? 我的代码:使用setTimeout运行的stop函数

function hidetrail() {
var x = document.getElementById("trailimageid").style;
x.visibility = "hidden";
document.onmousemove = "";

function followmouse(e) {

在发布的代码中,您不执行t因为displayduration为0,所以超时。另外我建议你改变'setTimeout(“hidetrail()”,displayduration * 1000);''someVar = setTimeout(hidetrail,displayduration * 1000);'someVar是在哪里定义的,去实现它。删除引号会删除隐藏的_eval_,这被认为是邪恶的 – mplungjan 2011-04-26 06:21:12
