Similar TutorialsHi, I need your help guys. I've got a little problem. I have some smileys which I enter to a textarea when clicking on them. It works perfect, but once the user clicks on a smiley, the focus goes off of the textfield. I use document.getElementById('message').value += smileycode It works perfectly, it enters the smileycode to the textarea. My problem is... When I say document.getElementById('message').focus() it goes back to where the cursors has last been so before the smileycode. Instead of this, I want the focus to go back after the insertion of the code. I hope it's understandable. And thanks in advance! Right so I have a popup window that when opened in any browser expect of course IE will open perfectly in the centre of the screen. However with IE it decides to jump to the top of the page, then is pushed back down to just show the popup at the bottom of the window. Anyone got any idea how I can stop this? Using IE8. Code: function openPopup_JD(params){
var name = params.name;
var blanket = params.blanket || true;
var effect = params.effect || "fade"
var afterOpen = params.afterOpen || "";
var width = document.getElementById(name).style.width;
var height = document.getElementById(name).style.height;
width = width.slice(0, -2);
height = height.slice(0, -2);
width = width * 1;
height = height * 1;
document.getElementById(name).style.left = getLeft_JD(width) + "px";
document.getElementById(name).style.top = getTop_JD(height) + "px";
//Create blanket if it doesn't already exist.
if(!document.getElementById('blanket')){
var popupBlanket = document.createElement("div");
popupBlanket.id = 'blanket';
popupBlanket.style.display = "none";
popupBlanket.style.opacity = 0;
popupBlanket.style.filter = 'alpha(opacity = 0)';
popupBlanket.style.backgroundColor = "#000";
popupBlanket.style.position = "absolute";
popupBlanket.style.zIndex = 9998;
popupBlanket.style.top = "0px";
popupBlanket.style.left = "0px";
popupBlanket.style.width = "100%";
popupBlanket.style.height = getBlanketHeight()+"px";
document.body.appendChild(popupBlanket);
}
switch(effect){
//-----------------------------------
//FADE IN
//-----------------------------------
case "fade":
if(blanket == true){
animate_JD({
objects: 'blanket |'+name,
properties: "opacity |opacity",
start: "0",
end: "0.75 |1",

Not all of the function is shown because below this are only other effects Hello all, I needs some help. I currently have a script to jump to an anchor tag when the page loads: Code: <script type="text/javascript">
function goToAnchor() {
location.href = "myPage.html#myAnchor";
}
</script>
Now, I would like to take it a step further and would like to link from page A to page B that usually takes a while to load and once the page loads, run a script to jump to the specified anchor tag on the page after everything has loaded. I know I have to add some parameters at the end of the url link on page A, but that's where I get stuck. Can anyone please help? I am using a Jump Menu: Code: function MM_jumpMenu(targ,selObj,restore){ //v3.0
eval(targ+".location='"+selObj.options[selObj.selectedIndex].value+"'");
if (restore) selObj.selectedIndex=0;
}
function MM_findObj(n, d) { //v3.0
var p,i,x; if(!d) d=document; if((p=n.indexOf("?"))>0&&parent.frames.length) {
d=parent.frames[n.substring(p+1)].document; n=n.substring(0,p);}
if(!(x=d[n])&&d.all) x=d.all[n]; for (i=0;!x&&i<d.forms.length;i++) x=d.forms[i][n];
for(i=0;!x&&d.layers&&i<d.layers.length;i++) x=MM_findObj(n,d.layers[i].document); return x;
}
function MM_jumpMenuGo(selName,targ,restore){ //v3.0
var selObj = MM_findObj(selName); if (selObj) MM_jumpMenu(targ,selObj,restore);
}
Code: <form name="FrontPage_Form1" language="JavaScript" onsubmit="return FrontPage_Form1_Validator(this)">
<!--webbot bot="Validation" b-disallow-first-item="TRUE" --><select name="menu" class="TextArea" onchange="MM_jumpMenu('self',this,0)">
<option value="javascript:myVoid()" selected>Choose One
</option>
<option value="1.html">One</option>
<option value="2.html">Two</option>
</select>
</form>
Is there some way to make such a jump menu observe the history, so that going back will go back to the page containing the form? Hi all, I'm having problems with a javascript jump menu that uses two select form elements, where the first one enables the second one if the right option is picked. I've not much knowledge of javascript so I've basically combined two separate functions, but at the moment only the second menu redirects the user - I need the first menu to do this as well if the second option is selected. Any ideas?! Here's the code - many thanks in advance if you can help: Code: <html>
<head>
<script type="text/javascript">
function chooseSelect(selectOption) {
document.getElementById('shape').disabled = (selectOption!=1);
}
function jumpMenu(select) {
var i = select.selectedIndex;
var selection = select.options[i].value;
var url;
if (i === 0) {
alert("Please select an option");
} else {
url = selection;
location.href = url;
}
}
</script>
</head>
<body>
<form action="" method="get">
<select name="color" id="color" onChange="chooseSelect(this.value);">
<option value="">- Choose Color -</option>
<option value="red.html">Red</option>
<option value="1">Shape</option>
</select><br />
<select name="shape" id="shape" disabled="disabled">
<option value="">- Choose Shape-</option>
<option value="square.html">Square</option>
<option value="circle.html">Circle</option>
<option value="rectangle.html">Rectangle</option>
</select><br />
<br />
<input type="button" value="GO" onclick="jumpMenu(this.form.shape);">
</form>
</body>
</html>

Thanks all. Hello I need some help with Google Maps please. Im using Google Maps API V3. So I can create a simple map but what I need is to have two markers (which are quite far apart) on the map. For example these markers are called 'Marker 1' and 'Marker 2'. Below the map I would have 2 links called for example 'Marker 1 link' and 'Marker 2 link'. When the map loads, 'Marker 1' is visible and centered. Now to move to 'Marker 2' on the map, I would click the link under the map. And vice versa. A good example is http://arts.brighton.ac.uk/contact-u...aculty-of-arts I tried but failed when I tried this guys answer on this website: http://stackoverflow.com/questions/2...utside-the-map Any help to create this is greatly appreciated! I'm probably not allowed to request something like this, but since this is a small amount of code I think I should do it anyways :P Okey, so I have two listboxes and I want a tickbox to enable one listbox and disable one listbox as you tick a checkbox. I want one listbox disabled by default and the other enabled and then vice-verca the disable when you tick the box. If someone could supply me with that code I would be really greatful, butyou don't need to bother with the HTML, I should figure it out from the JS. Thanks in advance <3 I am trying to populate a listbox using Javascript. The listbox is populated using the xml response from ajax request. Below is the code used for the same Code: var xmlDoc = xmlhttp.responseXML;
for (var i = 0; i < xmlDoc.getElementsByTagName("id").length; i++) {
traderlists.add(new Option(xmlDoc.getElementsByTagName("name")[i].childNodes[0].nodeValue, xmlDoc.getElementsByTagName("id")[i].childNodes[0].nodeValue));
}
This works fine for me. But i am facing performance issue here. some ajax requests retrieves xmls with around 11,000 nodes and this takes too much of time to populate the listbox. Can anyone please advice me with an better solution? Hi, I have an application wherein for one page I want to display a Listbox on selection of a radio button.

Each name has an onchange tag that calls up a floor map and that part works fine but I'd really like to populate the names from an XML list so it's easier for non-IT people to maintain. I've been doing alot of web searches on the subject which comes up alot but it's mostly just fragments of what I need being that I've got no javascript background. I found a helpful tutorial on javascriptkit but that wasn't for creating listboxes so I'm only part of the way there. This is the XML file I've got (there will eventually be 400 entries): <?xml version="1.0"?> <list> <employee> <name>##########</name> <office>1656</office> <officePH>(403)000-0000</officePH> <mobile>N/A</mobile> <email>##########</email> </employee> <employee> <name>#########</name> <office>1657</office> <officePH>(403)000-0000</officePH> <mobile>N/A</mobile> <email>###########</email> </employee> </list> The most important parts are the name which will be used as the text of the box and the office number which will determine which floorplan is displayed. I added the other information so I can potentially put it in a div display later but that can wait. Can anyone help point me to some good resources on this subject? Thanks. hello I have a listbox full of names on a PHP website and was wondering if there was a way to grab the value during a double click to bring me to another form to display the name and information? Hi there, I have a listbox and an Edit button. The user will need to click on the email address in the listbox before clicking on the button to edit. But then, the email address will be displayed on the prompt box's textbox, and even without editing it, the user can get scot-free. I would want to remove the email address on the prompt box's textbox, and also to check for null entries. If it is null, it will display an alert message. Else, it will check if it is a valid email address. My code is as follow: Code: function editItem()
{
var listbox = document.getElementById('listBox'); // listbox control id
var newValue = lst.value;
if(newValue != "")
{
var newItem = prompt("Enter the new email address",newValue);
if(newItem == "")
{
alert("Please key in an email address into the textbox.");
return false;
}
else
{
listbox.options[listbox.selectedIndex] = new Option(newItem,newItem,false,false);
return false;
arrTexts = new Array();
validRegExp =/^\w+@[a-zA-Z_]+?\.[a-zA-Z]{2,3}$/
// search email text for regular exp matches
if (arrTexts.value.search(validRegExp) ==-1 )
{
alert('A valid e-mail address is required.\nPlease try again.');
return false;
}
else
{
for(i=0; i<listbox.length; i++)
{
arrTexts[i] = lst.options[i].text;
}
arrTexts.sort();
for(i=0; i<listbox.length; i++)
{
listbox.options[i].text = arrTexts[i];
listbox.options[i].value = arrTexts[i];
}
}
}
}
else
{
alert('Select Item From The List To Edit ');
}
}
HTML Code: select id="lstBxEmail" name="listBoxEmail" size="6" style="width: 580px;"> <option>figFruit@msn.com</option> <option>apple@hotmail.com</option> <option>cherry@yahoo.com</option> <option>banana@hotmail.com</option> <option>elephantApple@ymail.com</option> <option>durian@gmail.com</option> </select> <select id="listBox" name="listBox" size="3" style="width: 580px;"> <option>hello@msn.com</option> <option>wowAmusers@hotmail.com</option> <option>yrulikethis@yahoo.com</option> </select> Essentially, I have an ASP.net page where I load a record set server side and upload it into a listbox. I'm trying to do all the movement functionalities of the listbox items client side. Specifically, I'm trying to figure out how to copy selected listbox items from one listbox to another -- on button click. I've searched for a while, but every example that I found moves the actual item into another listbox, I just want to copy the selected item to another listbox. I'm very new to JavaScript, so ff someone can provide an example or pseudo code, I would greatly appreciate it. Hello, I'm trying to fill an array with the values of a listbox from a SQL query but somehow I can only get the first word of each registry Code:
var arrayX=[];
function getValue(){
var x=document.getElementById("combo_color");
for (var i = 0; i < x.options.length; i++) {
if(x[i].value!=''){
arrayX.push(x[i].value);
}
}
}
for example, with the color Green Karanka I only get Green inside the array, the same happens with any color with more than one word, any ideas? Thanks. Hi, I've been working on a company directory page where a listbox called "People" in a form called "people_form" contains 400 employee names. I made the box "multiple" just so I could have it big and easier to find names but I decided a search box would be really useful. I've looked up a few such search scripts but so far the two I've tried haven't worked. The latest one when it's installed on the page, nothing happens when you type characters into it (it's supposed to jump to an entry matching the first few letters). Although if I backspace then it selects EVERY name in the list Here's the current form with the input tag being the search box (oh the options are populated by java script): <form name="people_form"> <input type="text" id="realtxt" onkeyup="searchSel()"></input> <select onchange="display(this.value); return false;" multiple="multiple" id="People" name="People" style="border-style: none; height:198px; width:220px;"> <option value="">Loading</option> </select></form> And here's the actual search function in the head of the page in the script tags: function searchSel() { var input=document.getElementById('realtxt').value.toLowerCase(); var output=document.getElementById('People').options; for(var i=0;i<output.length;i++) { if(output[i].value.indexOf(input)==0){ output[i].selected=true; } if(document.forms[0].realtxt.value==''){ output[0].selected=true; } } } If you know of a script that will work properly I'd appreciate it. For convenience I'm looking for one that jumps to selections inside the listbox as opposed to one where you click a search button and get results somewhere else. |
