I understand there are several ways to save checkbox information. The way that best fits this application is validating on the divID but the function is still not working. -
function checkCB() {
-
var inputs = document.getElementById(Filtered).getElementsByTagName('input');
-
for (var i=0; i<inputs.length ; i++)
-
{
-
var obj = inputs[i];
-
if(inputs[i].type == "checkbox") {
-
inputs[i].checked=false;
-
}
-
}
-
}
-
-
-
-
<input
-
type="checkbox"
-
class="checkbox"
-
id="Filtered"
-
name="title"
-
value="false"
-
/>
-
title

"Filtered" should be in quotes.
I managed to get the field in the URL showing the correct value onsubmit and the view source is correct as well. But the checkbox itself remains empty. -
function checkCB() {
-
var inputs = document.getElementById("Filtered").getElementsByTagName('input');
-
for (var i=0; i<inputs.length ; i++)
-
{
-
var obj = inputs[i];
-
if(inputs[i].type == "checkbox") {
-
inputs[i].checked="false";
-
}
-
}
-
}
-
-
-
<body onload="checkCB()">
-
-
<%
-
String title = request.getParameter("title");
-
if (title != "false")
-
{
-
title = "true";
-
}
-
%>
-
-
<input
-
type="checkbox"
-
class="checkbox"
-
id="Filtered"
-
name="title"
-
value="<%=title %>"
-
/>
-
title

Filtered is the name of the checkbox, so if you try to get the input elements from there, you won't get anything. Look for the parent element container for the checkbox and then use getElementsByTa gName.
I do appreciate your feedback aCoder although I'm not sure I understand what I need to key in on.

What exactly is checkCB() supposed to do? In your code, setting checked to false would mean that the checkbox is unchecked.
Once the checkbox is checked, the form is submitted to a second form. The second form includes the checkbox and I need it to be checked or unchecked depending on the user selection.
I must be getting mixed up if I am setting the box to false in my function.

In that case, you don't even need JavaScript (though you could use JavaScript too).
A checkbox is only passed through if it is checked, so in your JSP code, check that the value exists. If it does, set the checked attribute to "checked" or "true" for the checkbox using JSP.
I have this working but is there a cleaner way to recheck checkboxes on pagination? -
<%
-
String[] categories = request.getParameterValues("category");
-
String category = "";
-
if(categories != null)
-
{
-
for(int ii = 0; ii < categories.length; ii++)
-
{
-
category += categories[ii];
-
}
-
}
-
%>
-
<div class="item">
-
<input
-
type="checkbox"
-
id="cb1"
-
name="category"
-
value="cb1"
-
<% if (categories.indexOf("cb1") == -1) {%>
-
<% } else { %>
-
checked="yes"
-
<% } %>
-
Checkbox 1
-
</div>
-
<div class="item">
-
<input
-
type="checkbox"
-
id="cb2"
-
name="category"
-
value="cb2"
-
<% if (categories.indexOf("cb2") == -1) {%>
-
<% } else { %>
-
checked="yes"
-
<% } %>
-
Checkbox 2
-
</div>
-

The cleaner way would be to only check if checked: - <input
-
type="checkbox"
-
id="cb1"
-
name="category"
-
value="cb1"
-
<% if (categories.indexOf("cb1") != -1) {%>
-
checked
-
<% } %>>
-
Checkbox 1

I come from Oracle background. In Oracle, when one wants to do a point
in time
recovery, one can specify recover database until timestmap. Oracle's
database maps to a db2 subsystem, i.e., in Oracle database means
entire database, i.e.. all tablespaces (including indexes).
I see only recover tablespace and recover indexspace (or index)
commands in db2.
Therefore, one has to specify all the tablespaces and indexspaces and
recover them

Hi
I´ve got a problem with my scrollable table.
It´s a weekscheduler table with 7 columns ( weekdays ) and dynamicaly rows ( time ).
So the rows starts at 0:00am and ends at 12:00pm ( 24:00h ).
There is a value in the database, with a timeshift value ( in minutes ).
For example, timeshift value = 480 (480: 60 = 8) --> set scrollbar to 8:00am.
How can i set the scrollbar by pageload to the timeshift value?
