JavaScript - Bold Item In Listbox Javascript
Hi there, I would like to do the following:
When I click on a button, it will set the item in the listbox to be bold. But this will only happen when the user clicks on the desired item to be bold and presses the button. An alert message will occur when he/she presses the button without clicking on the item, stating that the user will need to click on the item. How shoukld I do it in javascript? Similar TutorialsHi Peers, i have a Drop down list with 10 choices (skillset). users must choose one skillset and the corresponding level (beginer/intermediate/master). ( they have to do this 10 times for all the sillsets) what i want is : 1 - i need to show up only one record (dropdowanlist) with level then have a button to add new skill and level if required 2- then when they choose the 1st skill from the dropdown , this one will not show up on the 2nd choice dropdown. is it possible any help ? thanks guys Hi there, I have this listbox that I want the user to select only one choice at a time. How do I disable the multiple selection feature in javascript? <select id="lstBxEmail" name="listBoxEmail" multiple="multiple" style="width: 580px;"> <option>Java</option> <option>PHP</option> <option>Perl</option> <option>Javascript</option> <option>C#</option> <option>Powershell</option> </select> <select id="lstBxEmail" name="listBoxEmail" multiple="multiple" style="width: 580px;"> <option>Java</option> <option>PHP</option> <option>Perl</option> <option>Javascript</option> <option>C#</option> <option>Powershell</option> </select> Hi, I would like to prevent the addition of duplicate items in the following situation. Firstly, I have a listbox with a few options such as Code: <select id="listbox" name="listbox" multiple="multiple" style="width: 580px;">
<option>Java</option>
<option>PHP</option>
<option>Perl</option>
<option>Javascript</option>
<option>C#</option>

</select>
Next, I have a submit button with a textbox. The user will be able to submit new options into the listbox via the textbox and submit button. Therefore, I need to prevent the user from entering duplicate items into the listbox. How should I do? The following code is used to add items into the listbox. Code: function addItem()
{
var lst = document.getElementById('listbox'); // listbox control id
var newItem = prompt("Enter New Item","Enter Value Here");
//Option object is created for every option in a selection
//new Option([text[, value[, defaultSelected[, selected]]]]) // Syntax
if(newItem == null)
{
return false;
}
else
{
lst.options[lst.length] = new Option(newItem,newItem,false,false);
return false;
}
}

This is my first javascript game and it's pretty much built of code I've gathered over time and cleaned up. Here's a manipulated screenshot of what I'm trying to accomplish. You're an ant and you want those goodies on the map as quickly as possible! click this link to view a bigger manipulated screenshot click this link to view the goodies (items) The ant is the playable character you control by using the arrow keys. Every time you load the page, or click "restart game", three new items will spawn randomly on the level and the time will be reset to 0 seconds. An arrow key must be pressed to start the time counter and the game itself. There are only 5 items so far, cheese, apple, banana, candy and donut. The items are supposed to be collected as quickly as possible, when the last item has been collected (by simply running over it) the game will end, save the time and display a hi-score list. Time limit is 30 seconds, the game will display a classic "GAMER OVER" if the limit is overrided. Problems I'm trying to solve: 1: Fullscreen mode (and make the ant actually STAY on the screen) I want the game level to adapt itself to the computer screen. The game dimensions are 1000x600px at the moment but the ant does not respect the level dimensions. Screenshot: http://i41.tinypic.com/kc1j81.jpg. I have a feeling about that somekind of percental code has to be implented but I've never done this before. (Please note that the size of the ant and the items will remain as they are) 2: Spawning three items randomly on the level I drew 5 items and saved them as 100x100 PNG. Three of these items have to spawn at a random location on the fullscreen level. The LAST item collected must trigger the time counter to stop. The time will later be used on the hi-score list where he/she can type her nickname. This information will be uploaded to a database. 3: 30 second time limit Letting the time counter reach 30 seconds will trigger a "GAME OVER". The only way to try again is page refresh or "restart game". Code: <html>

Hi, I have an application wherein for one page I want to display a Listbox on selection of a radio button. There should be 2 radio buttons and when the user clicks on the 2nd one "My Process", a list box should be displayed with several options. Can anybody pls help me with this as I'm a beginner to JS.. Many thanks Pooja. 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 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? 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. 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> 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. |
