Script
checkbox全选实现
function CheckOthers(form)
{
for (var i=0;i<form.elements.length;i++)
{
var e = form.elements[i];
// if (e.name != 'chkall')
if (e.checked==false)
{
e.checked = true;// form.chkall.checked;
}
else
{
e.checked = false;
}
}
}
function CheckAll(form)
{
for (var i=0;i<form.elements.length;i++)
{
var e = form.elements[i];
// if (e.name != 'chkall')
e.checked = true// form.chkall.checked;
}
}
建立表单对象，表单名：name=form，并建立checkbox，命名：name="checked"
建立全选按钮，代码：
<INPUT title=选择所有的Banner，点击选定按钮 onclick=CheckAll(this.form) type=button value=全选 name=chkall style="cursor:hand">
建立反选按钮，代码：
<INPUT title=反向选择所有的Banner，点击选定按钮 onclick=CheckOthers(this.form) type=button value=反选 name=chkOthers style="cursor:hand">
