Hi,

Pardon me if this question is already asked. I wonder if anyone know  
where I can find the snippet of code that will allow me to do “check  
all” and “uncheck all” in a list view of items. I am trying to see if  
there is any rails api i can use instead of “raw” javascript. Thanks in  
advance.

Regards,  
Chester

</div>

pass it the form id and true/false and this should do it:

function toggleCheck (form\_id, checked) {  
var form = $(form\_id);  
for (var i = 0; i \< form.elements.length; i++) {  
form.elements[i].checked = checked;  
}  
}

</div>

This should select and check all the inputs in the element with id  
‘#container’  
to uncheck them, just change the checked to false

```
<%=link_to_function "Select All", update_page {|page|

```

page.select(‘#container input’).each {|x|x.checked = true}}%\>

e.g this will check the following checkboxes

 i love ruby i love rails

Hope this helps!

Cheery-O!
