]]>Using Javascript to access/change control's propertyhttp://www.blogjava.net/programmer/archive/2007/08/30/165568.htmlwadewadeThu, 30 Aug 2007 06:31:00 GMThttp://www.blogjava.net/programmer/archive/2007/08/30/165568.htmlhttp://www.blogjava.net/programmer/comments/165568.htmlhttp://www.blogjava.net/programmer/archive/2007/08/30/165568.html#Feedback0http://www.blogjava.net/programmer/comments/commentRss/165568.htmlhttp://www.blogjava.net/programmer/services/trackbacks/165568.htmlSet readonly for input text

document.getElementById("ctrl_id").readOnly  = true; //pay attention to the readOnly, it's case sensitive.

 

Set option to unable to select for select control:

 

<option value="Genre" disabled="disabled">Genre</option>

 

Set select control to disabled (it has no readonly property):

 

<select disabled="disabled"></select>

 

Add a new option to a select control, it works under firefox 2.x and IE 5.x:

function addOption(select_ctrl, option_value, option_text){

var ctrl = document.getElementById(selectctl);



if(ctrl == null)

return;



var doc = ctrl.ownerDocument;

if (!doc)

doc = ctrl.document;



var opt = doc.createElement('OPTION');

opt.value = option_value;

opt.text = option_text;



ctrl.options.add(opt, ctrl.options.length);

}

 

Delete an option from select control:

selectctl.options[selectctl.selectedIndex] = null;

Delete all options from select control:

selectctrl.options.length = 0;

Change the css for an object:

document.getElementById("ctrl_id").className="SHOWN";
