javascript problem

hi all

is Javascript used in documentum different from normal javascript ?

i am working with jsp page where i used datagrid control with <dmf:checkbox> to rows and passed r_object_id as <dmf:arguments> to checkbox. I need to count how many rows I have retrieved from the query. when i use the following line of code it is showing me error

function somefunction ()

{

var max=document.checkbox.length;

alert(mar);

}

the somefunction is called when i select a checkbox and count the no.of rows in datagrid, but the error says "length" cannot be resolved.

if I use <input type =checbox> i am getting the what i want but i cannot pass r_object_id as parameter to the javascript function.

my question are :

1) if I use <dmf:checkbox > then how to get the length property in javascript

2) if i user <input type=checkbox > how to pass r_object_id as argument to javascript function

help me out............

Hi,

Why don't you use datagrid's dataprovider?

dataGrid.getDataProvider().getResultsCount() should do without javascript...

thanks for the reply but I want to count the no.of rows at client side rather than server side. as I have to count the no.of checkboxes clicked i need to enable or disable the buttons. i mean if i check only one check box edit button should be enabled or if i check more than one checkbox edit button should be disabled allowing not to edit more than one row at a time. for this i got a script which counts the no.of checkboxes clicked but if i integrate the same script in documentum its displaying errors.

here is the script

}
}

i want this script to run using <dmf:checkbox > in the datagrid control. I used like following but giving error at blue text....saying object doesn't support.

function anyCheck(form,objectId) {

var total = 0;

var max =document.getElementById("ckbox").length;

alert("Max "+max);

for (var idx = 0; idx < max; idx++) {
if (eval("document.form2.ckbox[" + idx + "].checked") == true) {

total += 1;
}
}
alert("You selected " + total + " boxes.");

}

can any one help on this..........

If you need to enable your Edit button only when one row is selected, then define an action button as "singleselect" dynamic property:

<dmfx:actionbutton name='edit' dynamic='singleselect' action='edit' ... />

Look at

Web_Development_Kit_6.5_Development_Guide.pdf, Page 121 and Web_Development_Kit_and_Webtop_6.5_Reference.pdf, Page 16.
