Javascript to select all checkboxes in visualforce page

 

I needed to develop a custom visualForce page which would hold a page block table which would contain a checkbox and details of a custom object based on which user can select and click on buttons to perform some operations.

 

 

I wrapped the custom object record and check box in a wrapper class. I needed a simple functionality when the header checkbox is selected or deselected accordingly all the checkbox will get selected or deselected accordingly. So i looked into community and first result community gave is this(controller way). It involved calls to back end and as a result functionality is little slow.

So I went for a Javascript solution which would provide a faster,elegant and much simpler way.Here is the VF code which was used in the page above.

 

‘checkedone‘)”/>

Id
Name

Note that I have set the id of the checkbox as checkedone and while clicking on header checkbox it calls a javascript function  checkAll. Giving an id will segregate all the checkboxes in the table. Here is the javascript which would handle the selecting and deselecting all of the checkboxes which has id checkedone in it.
