<script language="javascript">
if (parseInt(document.forms[0].txtbright.value) < 129) and (parseInt(document.forms[0].txtbright.value) > 1) and
(parseInt(document.forms[0].txtcontrast.value) < 129) and (parseInt(document.forms[0].txtcontrast.value) > 1) and
(parseInt(document.forms[0].txthue.value) < 129) and (parseInt(document.forms[0].txthue.value) > 1)
{
document.all("xplug").SetImageConfig(-1,-1,-1,document.forms[0].txtbright.value,document.forms[0].txtcontrast.value,document.forms[0].txthue.value,-1);
}
<script>

if 语言中的“与”和“或”是用"&&" 和"||" 来实现的

回菜鸟:
if ((parseInt(document.forms[0].txtbright.value) < 129) & (parseInt(document.forms[0].txtbright.value) > 1) &
(parseInt(document.forms[0].txtcontrast.value) < 129) & (parseInt(document.forms[0].txtcontrast.value) > 1) & (parseInt(document.forms[0].txthue.value) < 129) & (parseInt(document.forms[0].txthue.value) > 1))
{
}
原理：
if ((?) & (?) & (?))
{
}
if ((parseInt(document.forms[0].txtbright.value) < 129) & (parseInt(document.forms[0].txtbright.value) > 1) &
(parseInt(document.forms[0].txtcontrast.value) < 129) & (parseInt(document.forms[0].txtcontrast.value) > 1) & (parseInt(document.forms[0].txthue.value) < 129) & (parseInt(document.forms[0].txthue.value) > 1))
{
}
原理：
if ((?) & (?) & (?))
{
}
