RE: How to do JavaScript select all and de-selected all for checkboxes in t:dataTable

[Dave]

I have a dataTable. the first column is checkbox(s) for selection. but other columns have checkbox(s) too. How to select all checkbox(s) in the first column, not other columns?

 

Thanks.

If those are the only checkboxes in a form you can do the following:

 

 

f

function selectAllCheckBox(actionForm){

 

            for ( i = 0; i < actionForm.elements.length; i++ ) {

                        if (actionForm.elements[i].type == 'checkbox' ) {

                       

                                 &nbs p;  actionForm.elements[i].checked  = true; 

                       

                        }          

           

            }          

 

}

 

function clearAllCheckBox(actionForm){

           

            for ( i = 0; i < actionForm.elements.length; i++ ) {

                        if (actionForm.elements[i].type == 'checkbox' ) {

                       

                                    actionForm.elements[i].checked  = false;

                       

                        }          

           

            }          

 

}

 

 

function invertCheckBox(actionForm){

           

            for ( i = 0; i < actionForm.elements.length; i++ ) {

                        if (actionForm.elements[i].type == 'checkbox' ) {

                       

                                    if (actionForm.elements[i].checked == true) {

                                               

                                                actionForm.elements[i].checked  = false;

                                               

                                    }

                                    else {

                                   

                                                actionForm.elements[i].checked  = true; 

< SPAN style="FONT-SIZE: 10pt; COLOR: navy; FONT-FAMILY: Arial">                                   

                                    }          

                       

                        }

                                   

           

            }          

 

}

Subject: How to do _javascript_ select all and de-selected all for checkboxes in t:dataTable

 

Hi,

 

I am using <t:dataTable> to show the first column as the checkbox for each row. Is there a way to add "select all" and "de-select all" _javascript_ into these checkboxes? I don't want to go back to the server side to do such simple thing. Please shed some lights.

 

Thanks for your help!

Emily
