JavaScript - Set To Null Not Clearing Text Marker
This is some of the script that I have and it works well. The story is that I have a drop down list and depending on the selection a different set of text is displayed below the list.
Code: if (Val == "general")
{
document.getElementById('Link0').innerHTML="<font size=2><a Href='http://www.web1.com/'>web 1</a>"
document.getElementById('Link1').innerHTML="<font size=2><a Href='http://www.web2.com/'>web 2</a>"
However when the selection runs this part of the code:- Code: if (Val == "duties")
{
document.getElementById('Link0').innerHTML=""
document.getElementById('Link1').innerHTML="<font size=2><a Href='http://www.web2.com/'>web3</a>"
The "web 3" text is placed under where the 'Link0' text would have been if there had been some. So basically what I need to do is set the 'Link0' text to nothing and have the 'Link1' text sit in its place. I know I could just put the 'Link1' text in the 'Link0' element but I have other controls on the screen that mean I need to run it as it is. I hope that is clear, cheers Daniel. Similar TutorialsHey guys, First shot at JS so please be gentle! I'm trying to get this script to clear the default value of my input elements on focus. It works well the first time, however, if a user inputs some fresh text, selects something else, then selects the same input element again, it will clear the text they entered. Make sense? Here's the script (thanks in advance!!): Code: <script language="JavaScript">
function clickFocus(input){
input.className = 'focus';
if (input.value = input.defaultValue){
input.value = '';
}
}
function unFocus(input){
input.className = 'entered';
if (input.value == ''){
input.value = input.defaultValue;
input.className = 'normal'
}
}
</script>
<form action="confirmation.php" method="post" enctype="multipart/form-data" name="form" id="form" onsubmit="return checkForm(this)">
<input type="text" name="name" value="Name" onfocus="clickFocus(this)" onblur="unFocus(this)" />
<input type="text" name="email" value="Email" onfocus="clickFocus(this)" onblur="unFocus(this)" />
<input type="text" name="subject" value="Subject" onfocus="clickFocus(this)" onblur="unFocus(this)" />
<textarea type="text" name="message" onfocus="clickFocus(this)" onblur="unFocus(this)" rows="5">Message</textarea>
<input class="submit" name="submit"type="submit" value="Send Message" />
</form>
Hi- I have a table with numerous textareas that I am able to clear once - the first time the textarea is clicked the default value is cleared and everything is OK. However, at a certain point the user might press a 'Clear' button linked to a function I wrote to reset the values back to the defaults. At this point clicking into the textarea does not clear it. Below is a typical textarea: Code: <textarea rows= "2" cols="15" class="Klabel" id="ta5" onfocus="this.value=''; this.onfocus=null; setbg_color('ta5','#EFA746')" onchange="setbg_color('ta5', '#EBF5FF')">
Type a label
</textarea>
Below are the relevant functions. The Clear function mentioned above just runs 'setbg_color' and 'set_value' for each textarea and sets them to the defaults. Code: function setbg_color(id, color){
document.getElementById(id).style.background=color;
}
function set_value(id, celltype){
document.getElementById(id).value=celltype;
}
Is there anyway to essentially reverse the effects of the this.onfocus=null; statement? I tried something like this.onfocus=true; but that didn't work. An update - I haven't answered the reversing null question but an acceptable solution is to reload the page from within javascript as per http://www.mediacollege.com/internet...ge/reload.html Thanks -Jim ps - As part of my research I came across this http://mvied.com/blog/unobtrusive-input-clear-focus/ which does a smoother job of clearing the textareas but does not solve my question. Hi guys, Hopefully a really quick question. I'm a JS novice, and am looking for a way to output the coordinates of a Google maps marker into the value of two text fields, one for latitude and one for longitude. The code below is a simple location search which returns a result with a draggable marker. Currently, the coordinates in both text fields update when the location search is performed, but not when the marker is dragged to a new location afterwards. Does anyone know the code to simply update the coordinates each time the marker is dropped on a new location? Code: <html>

Many thanks in advance, I appreciate anyone who wants to help out! I need to clear the default value from a textarea when a user clicks on the textarea and then replace it if the user clicks away from the textarea without modifying it. I have managed to accomplish this with the textfields in my forms but I am struggling to get the textarea element to mimic this behavior. Here is the script I am using: Code: addEvent(window, 'load', init, false);
function init() {
var formInputs = document.getElementsByTagName('input');
for (var i = 0; i < formInputs.length; i++) {
var theInput = formInputs[i];
if (theInput.type == 'text' && theInput.className.match(/\binput\b/)) {
/* Add event handlers */
addEvent(theInput, 'focus', inputText, false);
addEvent(theInput, 'blur', replaceDefaultText, false);
/* Save the current value */
if (theInput.value != '') {
theInput.defaultText = theInput.value;
}
}
}
}
function inputText(e) {
var target = window.event ? window.event.srcElement : e ? e.target : null;
if (!target) return;
if (target.value == target.defaultText) {
target.value = '';
}
}
function replaceDefaultText(e) {
var target = window.event ? window.event.srcElement : e ? e.target : null;
if (!target) return;
if (target.value == '' && target.defaultText) {
target.value = target.defaultText;
}
}

I have it working on the text field but no the textarea. Help! Hi there, this is my first post. I'm very new to javascript and have been programming a "beer counter" that simply counts +1 into a text object after every click. After I got this to work I copied the code in order to make a clear button / function. I've been having problems, even though the code seems to be identical. This is likely an obvious question, pardon my inexperience. <html> <head> <title>Beer Counter</title></head> <body><script language="Javascript"> var beers = 0 var output ="" function beer() { beers = beers + 1 output = document.getElementById('output') output.value = beers } function clear() { beers = 0 output = document.getElementById('output') output.value = beers } </script> <input type='button' value='Crush' onclick='beer()'; /> Beer count:</input> <input type='text' id='output' name='output'; /><br/> <input type='button' value='Clear' onclick='clear()'; /> </body> </html> Hi, I have a form in which I preset some text inside a readonly, disabled textarea using javascript ('data' being the text): document.getElementById("link_of_current_view2").value = data; However, once I call my .php script to process the form, the element is null. How do I get it to pass along that data, which is in the textbox when the user views the form? Code: <div id="sendlink" class="contact_form" style="z-index:10;">
<a class="close" onclick="document.sendlink_form.reset();return false">CLOSE</a>
<form id='sendlink_form' name='sendlink_form' method="post" action="sendlink.php" >
<label for="link_of_current_view2">Link: </label>
<textarea id="link_of_current_view2" name="_of_current_view2" class="link_of_current_view" rows="2" disabled="disabled" wrap="soft" size="58" value="" readonly="readonly" value=/></textarea>
<input type="image" src="images/forms/submit.png" value="Submit" alt="Submit">
<a onclick="javascript:reset_sendlink()" style="cursor:pointer"><img src="images/forms/reset.png"></a>

Thanks for reading! Hi i have done some reading on the net today because i am getting an error on ie. I did find the javascript twice in my code, once in the header and once here, so i removed it from the header. I also changed to src to the full url. But i am still getting this and i dont know why. the file is located in the root directory.

Another Update. I am back to the original question. null is null or not an object.. in my search i have found this found a solution. basically Internet Explorer is crappy and doesnt like the setAttribute property so had to change the onchange handler by directly changing the attrbute for the object like so. object.onchange = function() {} i have no idea what they means, does that mean i need to change swfobject.js or does that mean i have to change my xml request. and if it is the swfobject i have no clue what they mean or what lines Hi I am having trouble with a script. I cannot figure out why I get the message: error: null is null or not an object (In IE8) The site is: www.rayburns.com I have check the javascript for the navigation bar and for the rotating images and cannot see what is missing. Not sure what is not being called. Can someone please help with this. Thank you in advance! Hey Guys, I am currently building a web app that uses Google Maps V3 api. You select a check box which then shows a marker on the map. My issue is, when you select and the marker is placed, I need the map to focus to that point, it currently embeds but doesn't focus. Is there a particular function I could use to achieve this? My current code is shown below: Code: var locations = [
// Longitude, Latitue, Content, Country Code, City Name
[51.481383, -3.114967, holidayOverlay, 'UK', 'Cardiff'],
[52.362393, 4.893379, holidayOverlay, 'NL', 'Amsterdam'],
[48.852314, 2.350089, holidayOverlay, 'FR', 'Paris'],
[40.18884, -3.716812, holidayOverlay, 'SP', 'Madrid'],
[53.800651, -4.064941, holidayOverlay, 'IT', 'Rome'],
[42.041134, 1.889648, holidayOverlay, 'SP', 'Costa Brava'],
[36.79334, 27.234421, holidayOverlay, 'GR', 'Kos'],
[37.014581, -7.933888, holidayOverlay, 'PT', 'Algarve'],
[28.358776, -14.05426, holidayOverlay, 'PT', 'Fuerteventura'],
[29.046854, -13.589973, holidayOverlay, 'SP', 'Lanzarote'],
];
// Only create marker when checked
for (i = 0; i < locations.length; i++) {
if (locations[i][4] == location) {
var marker = new google.maps.Marker({
position: new google.maps.LatLng(locations[i][0], locations[i][1]),
map: map,
icon: plotImage
});
var title = locations[i][4];
var content = locations[i][2];
}
}
I have left a lot of the code out to save you a headache. Thanks. hi, on my site: http://www.sbannister.co.uk/helix_site2/contact.html I am able to move my logo on my map, is there any way of locking it's position? thanks Hi i am building a gps tracker and i am having problems with the marker manager. I am pretty new to this stuff and i am sure my problem is quiet simple i just cant get my head around it. I posted my java script . If anyone can help it will be much appreciated. I am adding marker data from an xml file generated. I want to add a marker manager to the already existing markers generated to i add extra functionality on them. thanks for your time.

do i need to apply setInterval on the marker? how to apply it on the marker so it refresh every X second... please help for the solution.... I am having a problem with google maps api. i have created a map which will place a marker on the location entered in a text field.

Any Help greatly appreciated Hi, I am trying to add markers to Google Maps, they are working fine but some of the markers are of same location, thus Google Map will show only one marker for them. Is it possible to show all markers no matter if they are of same location. Help is much appreciated. Thanks Would someone as be so kind to check my google maps script. For some reason the map is centering yet no marker (and info window) is being displayed. I'm (foolishly) using php to echo out the lat and long and the info window content yet everything seems to output okay...... Did a quick java de-bug and found the following error; Quote: Error: myLatlng is not defined Source File: xxx Line: 45 However the lat and lng are echo' out okay and the map is centered on the co-ordinates???? Much thanks!!!! Code: <script type="text/javascript">
function initialize() {
var myOptions = {
center: new google.maps.LatLng(53.989723,-7.361760),
zoom: 13,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map(document.getElementById("map_canvas"),
myOptions);
var contentString = '<div>'+
'<h3 id="fs">Alcohol Early Intervention Project (Cavan/Monaghan)</h1>'+
'<div>'+
'<p>Click here for a streetview map</p>'+
'</div>'+
'</div>';
var infowindow = new google.maps.InfoWindow({
content: contentString
});
var marker = new google.maps.Marker({
position: myLatlng,
map: map,
title:"Alcohol Early Intervention Project (Cavan/Monaghan)"
});
var marker = new google.maps.Marker({
position: map.getCenter(),
map: map,
title: 'Click to zoom'
});
google.maps.event.addListener(marker, 'click', function() {
if (map.getZoom() == 13) {
map.setZoom(4);
} else {
map.setZoom(8);
}
});
}

Right I have google maps connected to a database which holds stockists and their information. The user enters their postcode and radius and markers are put on the map of stockists in the radius of their postcode. I have this all working fine and the database chucks the information into an xml file fine. The problem im having is displaying the information in the pop up window of the marker. PHP Code: <script type="text/javascript"> //<![CDATA[ var map; var geocoder; function load() { if (GBrowserIsCompatible()) { geocoder = new GClientGeocoder(); map = new GMap2(document.getElementById('map')); map.addControl(new GSmallMapControl()); map.addControl(new GMapTypeControl()); map.setCenter(new GLatLng(54.622978,-2.592773), 5); } } function searchLocations() { var address = document.getElementById('addressInput').value; geocoder.getLatLng(address, function(latlng) { if (!latlng) { alert(address + ' not found'); } else { searchLocationsNear(latlng); } }); } function searchLocationsNear(center) { var radius = document.getElementById('radiusSelect').value; var searchUrl = 'phpsqlsearch_genxml.php?lat=' + center.lat() + '&lng=' + center.lng() + '&radius=' + radius; GDownloadUrl(searchUrl, function(data) { var xml = GXml.parse(data); var markers = xml.documentElement.getElementsByTagName('marker'); map.clearOverlays(); var sidebar = document.getElementById('sidebar'); sidebar.innerHTML = ''; if (markers.length == 0) { sidebar.innerHTML = 'No results found.'; map.setCenter(new GLatLng(54.622978,-2.592773), 5); return; } var bounds = new GLatLngBounds(); for (var i = 0; i < markers.length; i++) { var name = markers[i].getAttribute('name'); var address1 = markers[i].getAttribute('address1'); var address2 = markers[i].getAttribute('address2'); var town = markers[i].getAttribute('town'); var county = markers[i].getAttribute('county'); var postcode = markers[i].getAttribute('postcode'); var telephone = markers[i].getAttribute('telephone'); var distance = parseFloat(markers[i].getAttribute('distance')); var point = new GLatLng(parseFloat(markers[i].getAttribute('lat')), parseFloat(markers[i].getAttribute('lng'))); var marker = createMarker(point, name, address1, address2, town, postcode, telephone); map.addOverlay(marker); var sidebarEntry = createSidebarEntry(marker, name, town, distance); sidebar.appendChild(sidebarEntry); bounds.extend(point); } map.setCenter(bounds.getCenter(), map.getBoundsZoomLevel(bounds)); }); } function createMarker(point, name, address1, address2, town, postcode, telephone) { var marker = new GMarker(point); var html = '<b>' + name + '</b> <br/>' + address1 + '<br />' + address2 + '<br />' + town + '<br />' + postcode + '<br />' + telephone; GEvent.addListener(marker, 'click', function() { marker.openInfoWindowHtml(html); }); return marker; } function createSidebarEntry(marker, name, town, distance) { var div = document.createElement('div'); var html = '<b>' + name + '</b> (' + distance.toFixed(1) + ')<br/>' + town; div.innerHTML = html; div.style.cursor = 'pointer'; div.style.marginBottom = '5px'; GEvent.addDomListener(div, 'click', function() { GEvent.trigger(marker, 'click'); }); GEvent.addDomListener(div, 'mouseover', function() { div.style.backgroundColor = '#eee'; }); GEvent.addDomListener(div, 'mouseout', function() { div.style.backgroundColor = '#fff'; }); return div; } //]]> </script> Example Xml: PHP Code: <markers> <marker name="AVON ANGLING CTR" address1="348 WHITEHALL ROAD" address2="ST.

I've been looking for a solid solution for how to add numbers to markers. Most that I've seen involve an asp page with a post back of an image based on the query string. I am trying to do something like what MarkerClusterer does. Here is an example: http://google-maps-utility-library-v...e_example.html I've looked over their code and cant seem to pull out the part where it adds the numbers to the marker, I'm still new to jquery. Here is a link to the source code: http://google-maps-utility-library-v...erclusterer.js any help would be appreciated. how can I get my custom markers to show? I have got my code in place, everything works except, doesn't show my custom marker?! here is my code: Code: <script type="text/javascript">
//<![CDATA[

// of the "marker" and "html" variables which will be needed
later when the event triggers.
function createMarker(point,html) {
var marker = new GMarker(point);
GEvent.addListener(marker, "click", function() {
marker.openInfoWindowHtml(html);
marker.image = "images/google-pin.png";
marker.shadow = "images/google-pin-shadow.png";
marker.iconSize = new GSize(90, 70);

return marker;
}
// Display the map, with some controls and set the initial

Hi I've implemented Busybox on a website to display FLV files in a popup player. This works fine, except for the following error in IE (FF is fine) when I close the popup: 'null' is null or not an object I think I've narrowed it down to the following block of code, but am stuck as to what to do from here. Code: var cl = new Element('img',{
'styles':{
width:'24px',
height:'24px',
position:'absolute',
top:'-20px',
right:'-20px',
'z-index':'100000'
},
'src':'bumpbox/closed.png',
'id':'closer'
})
cl.addEvent('click',function(e){
e = new Event(e).stop();
bg.dispose();
$(el).getChildren().dispose();
eff2.start({
'width':[maxw,1],
'height':[maxh,1],
'left': [endleft,middleH],
'top': [endtop, middleV+s]
})
})
The IE error is just giving me line number 1 of the php, but the error, I'm sure, lays in the Javascript. Many thanks |
