When writing form tag in HTML, following javascript is very useful. This will be very helpful.
//int mode
// mode = 0 invert selection
// mode = 1 Select None
// mode = other than 0 or 1, Select All
function checkChange(mode)
{
for(i=0;i<document.forms[0].elements.length;i++)
{
var ele = document.forms[0].elements[i];
if(ele.type == 'checkbox')
{
if(ele.disabled=false)
{
if(mode==0) //invert selection
ele.checked = !ele.checked;
else if(mode==1) //none
ele.checked = false;
else
ele.checked = true;
}
}
}
}
// mode = 0 invert selection
// mode = 1 Select None
// mode = other than 0 or 1, Select All
function checkChange(mode)
{
for(i=0;i<document.forms[0].elements.length;i++)
{
var ele = document.forms[0].elements[i];
if(ele.type == 'checkbox')
{
if(ele.disabled=false)
{
if(mode==0) //invert selection
ele.checked = !ele.checked;
else if(mode==1) //none
ele.checked = false;
else
ele.checked = true;
}
}
}
