Hi again Folks

I had another learning bump I'm going to ask

Well I can't seem to hide the selector that I'm supposed to hide.. well to see for yourselves here's the link..'
http://dev.crownshipping.com.ph/single_update.html

I have a list of boats.. and each one of them has details..
Code:

<ul>
    <li>boat1 details</li>
     <li>boat2</li>
     <li>boat3</li>
</ul>

initially the boat details are hidden... so when i click the boat a modal window pops up.. and a dialog where you can see the boat details..

during the first try.. everything is okay.. but when i close the modal window.. when i click another boat to view, the previous one that was not supposed to show.. were displayed....

I have tried hiding it.. by doing $('class name').hide();.. also I have tried setting the css again to display:none.. but still a no go..

I'm fairly new to javascript and jquery so please help me.. I have tried all that I have learned.. maybe there's a trick that i still don't know..

here's the js code.. hope someone can help me be easy on me.. i just started 2 days ago.. i'm on day 3

Thanks

Code:

$(document).ready(function() {	

	//select all the a tag with name equal to modal
	$('a.modal').click(function(e) {
		//Cancel the link behavior
		e.preventDefault();
		
		//Get the A tag value to match with class name later
		var id = $(this).attr('href');
		//document.write (id);
	
		//Get the screen height and width
		var maskHeight = $(document).height();
		var maskWidth = $(window).width();
	
		//Set heigth and width to mask to fill up the whole screen
		$('#mask').css({'width':maskWidth,'height':maskHeight});
		
		//transition effect		
		$('#mask').fadeIn(1000);	
		$('#mask').fadeTo("slow",0.8);	
	
	
		//transition effect
		$('.window').fadeIn(1000);
		
		if(id=="" || id=="#")
		{var check = "";
		document.write ('no value!');}
		else{
		var check = '.' + id;
		//document.write (check);
		$(check).fadeIn();
		} 
		
	
	});
	
	//if close button is clicked
	$('.window .close').click(function (e) {
		//Cancel the link behavior
		e.preventDefault();
		$('#mask, .window').fadeOut(1000);
		
	//	$('.window').hide();
	});		
	
});

Hey guys,

Is there a way of hiding a whole table row if a certain cell inside it is empty?

Thanks,

Adam

I need some help as this is driving me crazy.

I have a onblur, focus with this code for the columns of footer filter.

Code:

$("tfoot input").keyup( function () {
		/* Filter on the column (the index) of this element */
		oTable.fnFilter( this.value, $("tfoot input").index(this) );
	} );
	
	$("tfoot input").each( function (i) {
		asInitVals[i] = this.value;
	} );
	
	$("tfoot input").focus( function () {
		if ( this.className == "search_init" )
		{
			this.className = "";
			this.value = "";
		}
	} );
	
	$("tfoot input").blur( function (i) {
		if ( this.value == "" )
		{
			this.className = "search_init";
			this.value = asInitVals[$("tfoot input").index(this)];
		}
	} );

I am clearing the input fields with this.

Code:

$("input:button").click(function(e) {	$('#col1').val(''); 
					$('#col2').val('');
					$('#col3').val(''); 
					$('#col4').val('');
 					$('#col5').val('');

Including a reset of the filters, but won't bore with that, it works, the filters for the columns are all released and reset.

My issue is the tfoot fields are cleared just fine, but remain blank. The onblur values do not refill the fields until I click in, then click out of the input field. Do I need to adjust for the clearing of the input field in the original focus and onblur? Or do I need a better reset of the the .val('') statement with a tweak to let the onblur function to show.

Thanks, any help really appreciated.

Hi. I have a form and if a field is blank a message pops up. This doesnt stop my php from running though and takes the user to another page.

Is there a line to keep them on that page untill all fields are filled out?

code so far is simple.

<script type="text/javascript" language="JavaScript">
function nameempty()
{
if ( document.form.subject1.value == '' )
{
alert('No name was entered!')
return false;
}
}
</script>


//then down the bottom I have a small bit that implements that code

I have a index page on which there are several iframes which point to pages from a tomcat server. Sometimes when the index page loads, most of the iframes display session expired error. When I refresh the page, all iframes load properly. I want to
reload the page twice whenever I come to that page initially. I also want to reload that page twice when I come to it from another page. Any ideas are welcome.

I have tried the following in the onload event

-----------------
if(window.location.search.indexOf('reload')<0) window.location.replace(window.location.href+'?reload');

---------------

function loaded()
{ if (!navigator.fudge) {
navigator.fudge = 0;
}
navigator.fuge++;
if (navigator.fudge>1){navigator.fudge=0}
else{location.reload()};
}

-------------

if(readCookie('reloaded')!='Yes')
{
createCookie('reloaded','Yes',1);
window.location.reload();
}
else
eraseCookie('reloaded');

function createCookie(name,value,days) {
if (days) {
var date = new Date();
date.setTime(date.getTime()+(days*24*60*60*1000));
var expires = "; expires="+date.toGMTString();
}
else var expires = "";
document.cookie = name+"="+value+expires+"; path=/"; }

function readCookie(name) {
var nameEQ = name + "=";
var ca = document.cookie.split(';');
for(var i=0;i < ca.length;i++) {
var c = ca[i];
while (c.charAt(0)==' ') c = c.substring(1,c.length);
if (c.indexOf(nameEQ) == 0) return c.substring(nameEQ.length,c.length);
}
return null;
}

function eraseCookie(name) {
createCookie(name,"",-1);
}

---------------------------
several meta tags to get the page each time from the server

e.x.
<META HTTP-EQUIV="Pragma" CONTENT="no-cache">
<META HTTP-EQUIV="Expires" CONTENT="-1">

Hi all,

PHP Code:

I'd like to show table_pkg and hide pkg when I click on <a>text</a>.
How can I do?

I have a script to show and hide various divs based on a function & var.

The problem im having is that when ANY of the variables ('hate', 'ok' and 'love') are passed all 3 different feedback forms ('FeedbackHate', 'FeedbackOk' and 'FeedbackLove') appear, not just the one I want.

here is the JS:

Code:

function sitesurveyswitch(emotion) {

	var e = emotion;

	document.getElementById('site_survey_hate').style.backgroundPosition = '0px 0px';
	document.getElementById('site_survey_ok').style.backgroundPosition = '0px 0px';
	document.getElementById('site_survey_love').style.backgroundPosition = '0px 0px';
	document.getElementById('FeedbackHate').style.display = 'none';
	document.getElementById('FeedbackOk').style.display = 'none';
	document.getElementById('FeedbackLove').style.display = 'none';
		
	if (e == 'hate')
		document.getElementById('site_survey_hate').style.backgroundPosition = '-80px 0px';
		document.getElementById('FeedbackHate').style.display = 'block';
	if (e == 'ok')
		document.getElementById('site_survey_ok').style.backgroundPosition = '-80px 0px';
		document.getElementById('FeedbackOk').style.display = 'block';
	if (e == 'love')
		document.getElementById('site_survey_love').style.backgroundPosition = '-80px 0px';
		document.getElementById('FeedbackLove').style.display = 'block';
}

and here is the code related to this function:

Code:

<div id="siteSurveyBox">
				<span id="site_survey_hate" onclick="sitesurveyswitch('hate');return false;"></span>
				<span id="site_survey_ok" onclick="sitesurveyswitch('ok');return false;"></span>
				<span id="site_survey_love" onclick="sitesurveyswitch('love');return false;"></span>
			</div>
			
			<div id="FeedbackHate" style="display:none; margin-top:-28px;">
				FEEDBACK FORM IS HERE
			</div>
			
			<div id="FeedbackOk" style="display:none; margin-top:-28px;">
				FEEDBACK FORM IS HERE
			</div>
			
			<div id="FeedbackLove" style="display:none; margin-top:-28px;">
				FEEDBACK FORM IS HERE
			</div>

Hello,

I have the folowing code but it seems to be broken between "SM Decision Support" and "Incident and Request Management".

Does anyone know how I resolve ?.

The idea is when somebody opens the page all the sections are hidden/uncollapsed and the user can collapse individually each section with a click or by hitting the expand/collapse all link.

I don't know a lot about Javascript... still learning..
I am trying to create a show/hide effect that displays an image based on the users text input. I have coded this before for a list/menu and it works fine. With this particular project there are too many selections to choose from to put in a list/menu. I am trying to use if and else if statements to make this work. With the code the way it is only the first function on the list works. I tried just using repeating if statements and only the last function on the list works. Here is the code:
Code:

<script type="text/javascript" >

function showSample() {
	
  if (document.getElementById('input').value='SW001') {
	document.getElementById('SW001').style.display='block';
    document.getElementById('SW002').style.display='none';
    document.getElementById('SW003').style.display='none';
    document.getElementById('SW004').style.display='none';

  }
  else if (document.getElementById('input').value='SW002') {
	document.getElementById('SW001').style.display='none';
    document.getElementById('SW002').style.display='block';
    document.getElementById('SW003').style.display='none';
    document.getElementById('SW004').style.display='none';

  }
  else if (document.getElementById('input').value='SW003') {
	document.getElementById('SW001').style.display='none';
    document.getElementById('SW002').style.display='none';
    document.getElementById('SW003').style.display='block';
    document.getElementById('SW004').style.display='none';

  }
    else if (document.getElementById('input').value='SW004') {
	document.getElementById('SW001').style.display='block';
    document.getElementById('SW002').style.display='none';
    document.getElementById('SW003').style.display='none';
    document.getElementById('SW004').style.display='none';

  }
  
    else if (document.getElementById('input').value='SW005') {
	document.getElementById('SW001').style.display='none';
    document.getElementById('SW002').style.display='none';
    document.getElementById('SW003').style.display='none';
    document.getElementById('SW004').style.display='block';

  }

}
