複製代碼代碼如下：
//表格選擇
功能ClearForm（ID）{
var formObj = document.getElementById（id）;
if（formObj == undefined）{
返回;
}
for（var i = 0; i <formobj.elements.length; i ++）{
if（formobj.elements [i] .type ==“ text”）{
formObj.elements [i] .value =“”;
}
否則if（formobj.elements [i] .type ==“密碼”）{
formObj.elements [i] .value =“”;
}
否則if（formobj.elements [i] .type ==“無線電”）{
formobj.element [i] .checked = false;
}
否則if（formobj.elements [i] .type ==“複選框”）{
formobj.element [i] .checked = false;
}
else if（formobj.elements [i] .type ==“ select-One”）{
formObj.elements [i] .options [0] .selected = true;
}
否則if（formobj.elements [i] .type ==“ select-multiple”）{
for（var j = 0; j <formobj.elements [i] .options.length; j ++）{
formObj.elements [i] .options [j] .selected = false;
}
}
否則if（formobj.elements [i] .type ==“ file”）{
// fommobj.elements [i] .select（）;
//document.selection.clear（）;
//對於IE，Opera，Safari，Chrome
var file = formobj.elements [i];
if（file.outerhtml）{
file.outerhtml = file.outerhtml;
}別的{
file.value =“”; // FF（包括3.5）
}
}
否則if（formObj.elements [i] .type ==“ textarea”）{
formObj.elements [i] .value =“”;
}
}
}
