while(m.offsetParent)
{
h += m.offsetTop;
m = m.offsetParent;
}
m = document.getElementById('div_info');
var t = 0;
while(m.offsetParent)
{
t += m.offsetTop;
m = m.offsetParent;
}
var yy = document.getElementById('txt_YY').value;
if (y > 74)
{
if (h <= y && y < t)
{
document.getElementById('txt_YY').value = "1";
}
else
{
document.getElementById('txt_YY').value = "0";
}
}
}
2. 调用js:
<body onmousedown="whichElement(event)">
