The cgi|dhtml| client//page is displayed, and the following task is to operate on them. The following are the foreground JavaScript functions. In the first step, the option value of the selection box Selcategory is generated first in the Window.onload event based on the array acategory.
function On_load ()
{
Class
Frmmanager.btnchangemaster. Disabled = true;
Frmmanager.btnchangename. Disabled = true;
Frmmanager.btndeletecategory. Disabled = true;
Frmmanager.btndown. Disabled = true;
Frmmanager.btnmodifydescription. Disabled = true;
Frmmanager.btnup. Disabled = true;
Frmmanager.btnaddforum. Disabled = true;
Frmmanager.btndeleteforum. Disabled = true;
To first generate Selcategory option
frmManager.selCategoryName.options.length = 0;
for (var i = 0; i < acategory.length; i++)
{
var newoption = document.createelement ("option");
Newoption.value = Acategory[i]. CategoryID;
Newoption.text = Acategory[i]. CategoryName;
Frmmanager.selcategoryname. Add (newoption, i);
}
}
In the second step, we use the Selcategory onchange events to realize the Selforum display, and use the onchange events of Selform to realize the display of their relevant information.
function On_categorychange ()
{
Frmmanager.btnchangename. Disabled = false;
Frmmanager.btndeletecategory. Disabled = false;
Frmmanager.btndown. Disabled = false;
Frmmanager.btnup. Disabled = false;
Frmmanager.btnaddforum. Disabled = false;
Frmmanager.btnmodifydescription. Disabled = true;
Frmmanager.btnchangemaster. Disabled = true;
Frmmanager.btnaddcategory. Disabled = false;
Frmmanager.btndeleteforum. Disabled = true;
frmManager.selForumName.options.length = 0;
if (frmmanager.selcategoryname. SelectedIndex!=-1)
{
FrmManager.txtCategoryName.value = Frmmanager.selcategoryname[frmmanager.selcategoryname.selectedindex].text;
}
FrmManager.txtForumName.value = ""
Frmmanager.txtdescription. Value = "&quo
