JavaScript - Delete Item Function
This function is part of a page that will delete a product that a customer has selected.
The question I have is what is the line line that actually removes the item from the list of products chosen? From my understanding, in order to establish an array, new array = elements[i] has to be added but Im thinking that elements[i] is the array that holds the product. Does the "0" in this line actually delete the item? document.template.elements[i].value = 0 ; Code: function del_item(X,msg) {
// var msg = "Are you sure you want to delete this line item?"
resp = confirm("Are you sure you want to " + msg + "?") ;
if (resp) {
var len = document.template.elements.length
//loop to put into arrays
for (var i = 0; i < len; i++) {
var lname = document.template.elements[i].name ;
if(lname == X) {
document.template.elements[i].value = 0 ;
process_order(0) ;
document.template.loginpath.value = "CO" ;
document.template.submit() ;
}
}
} else {
return ;
}
}
Similar TutorialsI'm still a relative noob and i'm wondering if anyone can help. items use a structured form, so any item in that category will display on the same form when selected i want to have the save button run its normal save on all items except 1 specific item - on the 1 item i want to have it function as a save as copy (while still having "save" as its visible text), the current code set in a drop down list is $options[] = array( 'text' => 'JSAVE', 'task' => $this->getName() . '.save'); $options[] = array( 'text' => 'Save as new project', 'task' => $this->getName() . '.save2copy', 'options' => array('access' => ($this->item->id > 0))); can anyone offer any suggestions? really stuck on this one Hi All, I am working on a script that creates a table, taking the data from a number of text fields and populating the table cells with it. Originally I had to start with an existing table containing one blank row but I was able to get the script to create the table dynamically. Unfortunately I seem to have broken my delete row function (this was working fine when the script started with an existing table). The error I am getting is: TypeError: 'cells.0.childNodes' is null or not an object I googled this but could not find anything to help. I don't have alot of javascript experience and need help from the experts. Thanks in advance for all your help guys!

The issue I am having is that I want the hover image (red part) to be displayed only when hovering the root li, and not all subsequent li items in the menu.. because as you may see now, even when hovering the li in the submenu the red gets displayed. The code I am using is the following Code: <script type="text/javascript">
$(document).ready(function () {
$('#smoothmenu1 li').append('<div class="hover"></div>');
$('#smoothmenu1 li').hover(
function() {
$(this).children('div').fadeIn('500');
},
function() {
$(this).children('div').fadeOut('500');
}).click (function () {
$(this).addClass('selected');
});
});
</script>
and Code: <div id="smoothmenu1" class="menu">
<ul>
<li><a href="#">Page 1</a></li>
<li><a href="#">Page 2</a>

Is there a way to specify in the javascript functionality where to append the div to only the root li item? Thanks hai friends <script type="text/javascript"> function myfunction(x) { var xname = x.name; alert("gender - " +xname); } </script> </head> <body> <form action="index.php" method="post" name="frm2" id="frm2"> <input type="checkbox" name="male" onclick="myfunction(this)" /> male <input type="checkbox" name="female" onclick="myfunction(this)" /> female </form> when i use this code only check box which is selected will alerts me . i want all checkboxes names which are selected as alert plz help me Hi, I have a list setup with links. The list scrolls with the css setting of overflow:auto. However, when a link in the list that is scrolled down to (that is hidden unless scrolled down to) is clicked, I'd like to hold the list at that list item so that the viewer can return to the same line in the list and click the next li. Right now, the list resets to the top after a li link is clicked... I have a feeling this is something simple, but I'm guessing it would be javascript...?? The site to view - click here and then see the left side scrolling list. Thanks!! I'm trying to delete a item in a list. I'm getting a method not allowed error in IE8. Code: var selectOptions = document.getElementById('id_employees_cbo');
for (var i=0; i<selectOptions.options.length; i++)
{
if (selectOptions.options[i].selected == true)
{
selectOptions.options[i].remove();
break;
}
}
Is there another way to do this? Thanks Hello everyone. This a css code in <head>: Code: .pagination{
width: 530px; /*Width of pagination DIV. Total width should equal slider's outer width (400+10+10=420)*/
text-align: right;
background-color: white;
padding: 5px 10px;

.pagination a{
padding: 0px 5px;

}
.pagination a:hover, .pagination a.selected{
color: white;
text-decoration: none;
font-weight:bold;
font-family:Arial;
background-color: #410B38;
}
for a div with class=pagination (below) which contains the pagination of mysql data display: Code: <div class="pagination">

$rs_result = mysql_query($sql,$mysql_connection);
$row = mysql_fetch_row($rs_result);
$total_records = $row[0];
$total_pages = ceil($total_records / 5);
for ($i=1; $i<=$total_pages; $i++) {

I want everytime someone clicks on another number in order to change page, that clicked number to have different style than the other numbers as long as one stays on that page and when one clicks on a different number I want that number to behave in the same way. Someting like highlighting the navigational item that you're on. Thank you very much in advance! i have tried searching the forums for help but really am getting no where. i am trying to call an array item from an input box. the input is all numbers. the arrays are v + numbers. i cannot seem to figure out how to get the item from the array. eg Code:
var v00501 = ["HOLTSVILLE,I R S SERVICE CENTER","NY","631","-5","Y"]
var v00544 = ["HOLTSVILLE,IRS SERVICE CENTER","NY","631","-5","Y"]
var v00601 = ["ADJUNTAS,JARD DE ADJUNTAS,URB SAN JOAQUIN","PR","787/939","-4","N"]
function pop() {
var zipv = "v" + myform.Zip.value +"[0]";
alert(zipv);
}
or Code:
function pop() {
alert(pop1());
}
function pop1() {
return "v" + myform.Zip.value +"[0]";
}
so for this if the user typed in 00501 i get v00501[0] no matter what i try. i want HOLTSVILLE,I R S SERVICE CENTER to be returned or whatever item i am calling for. this all has to be on client side as i dont have server access so the zip codes are all set up as arrays in a seperate file. i really dont know alot about javascript but i am learning. any help on how i can accomplish this would be appreciated. This is the code that I have:- Code:
ListItem[1] = new Option("A List Item", "listitem1");
ListItem[1].style.display = "none";
The first line creates a new entry in the list, I am wanting the second line to remove the same item but it doesn't work. I have tried this:- Code: ListItem[1] = new Option("");
But that leaves a blank line entry in the list Cheers Daniel. Hi Guys, I'm using jcarousellite to show my newsitems in a vertical carousel. http://www.gmarwaha.com/jquery/jcarousellite/ The carousel itself works perfectly, now I'm trying to add that before the news scrolls upwards the top news-item fades-out first. Now it is fading out the complete list and I simply can't seem to figure out how to 'talk' to the 'active/top' <li> in the list. Can someone give me a hint? Thanks in advance, Marcel -- Code Below -- Code: $(function() {
$(".widgetCarousel").jCarouselLite({
circular: true,
vertical: true,
visible: 3,
scroll: 1,
start: 1,
auto: 500,
speed: 1000,
beforeStart: function(a) {
$(a).parent().fadeTo(100, 0);
},
afterEnd: function(a) {

}
});

Hi Guys, i have two different arrays with the same number of element. The 1st array holds the ID's and the 2nd one holds the Items.. i want to use both of them in a Jquery autocomplete plugin.. showing the the 2nd one values but getting the value of the 1st arr. I was wondering if there is a way to combine both in one in Javascript like Arr3 =[arr1, arr2] where i display arr2 elemnt and pass arr1 elements? thanks Hi I have copied and adapted the commonly found switchmenu script available widely on the web from Dynamic Drive. I understand that it might be dated now, but I am limited as to what I can do. Specifically, this code has to sit in a webpart within Sharepoint 2003, so no referencing external CSS or js files. The code below functions as desired, and opens the items one at a time, closing the previous before opening the next. However, what I want to do is have the first item default to being open. Any pointers? putting a onload in a body tag isn't an option (this code is popping into a webpart in sharepoint, so no access to the body tag). Many thanks -------------------------- <script type="text/javascript"> var persistmenu="yes" //"yes" or "no". Make sure each SPAN content contains an incrementing ID starting at 1 (id="sub1", id="sub2", etc) var persisttype="sitewide" //enter "sitewide" for menu to persist across site, "local" for this page only if (document.getElementById){ //DynamicDrive.com change document.write('<style type="text/css">\n') document.write('.submenu{display: none;}\n') document.write('</style>\n') } function SwitchMenu(obj){ if(document.getElementById){ var el = document.getElementById(obj); var ar = document.getElementById("masterdiv").getElementsByTagName("span"); //DynamicDrive.com change if(el.style.display != "block"){ //DynamicDrive.com change for (var i=0; i<ar.length; i++){ if (ar[i].className=="submenu") //DynamicDrive.com change ar[i].style.display = "none"; } el.style.display = "block"; }else{ el.style.display = "none"; } } } function get_cookie(Name) { var search = Name + "=" var returnvalue = ""; if (document.cookie.length > 0) { offset = document.cookie.indexOf(search) if (offset != -1) { offset += search.length end = document.cookie.indexOf(";", offset); if (end == -1) end = document.cookie.length; returnvalue=unescape(document.cookie.substring(offset, end)) } } return returnvalue; } function onloadfunction(){ if (persistmenu=="yes"){ var cookiename=(persisttype=="sitewide")?

When clicked, each one dynamically loads a new Flash movie via Javascript, within the same page. This works fine. However, what I would really like, is to have each menu item highlighted after it has been clicked, to show the user what is being shown. This could be the same image as is displayed in the active CSS state. Does anyone know how I can do this? Because each link is simply dynamically loading flash movies, and not going to a new html page, I can't simply add an ID element. Take a look at a basic example I've mocked up, and see the code below: CSS: Code: #navlist {
font-family:Arial, Helvetica, sans-serif;
font-size:.8em;
font-weight:bold;
list-style:none;
}
#navlist a {
display:block;
width:155px;
color:#fff;
text-decoration:none;
background:url(../images/tab.gif) no-repeat;
padding-top: 7px;
padding-right: 4px;
padding-bottom: 6px;
padding-left: 10px;
}
#navlist a:hover {
background-position:0 -29px;
color: #1e5ebd;
}
#navlist a:active {
background-position:0 -58px;
color:#1e5ebd;
}

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? Ok so let's say I have this dropdown with a list of these items: PALCO TRIBUNA ORO And in a button on the page I want to send it one of those names, let's say I send it ORO, and through Javascript select that in the dropdown list. How is this done? Do I have to iterate through everything, and how? Thanks for any help in the subject. I created an array, whose entries looks like this: [41, "The bird flew into it's cage"] [33, "He drew fire from Joe"] [33, "Roger asked her her name"] [2, "I am awfully happy"] . I want to pull the sentence item out of some array entries. E.g., in the second entry, namely, arrayName[1], what I thought was the second item (the sentence), I could manage by invoking arrayName[1][1] . But to my dismay, this doesn't do the trick. arrayName[1][1] actually delivers up the second CHARACTER of the entry (the number "3"). I thought the comma between the number and the sentence would separate the items, although I "pushed" each entry into the array as one single entry. How do I "grab" the whole sentence? How do I push both items separately to achieve "one entry"? This is the code that I have, on selecting the first item in the first list it populates the second list with users. What I need to do is create a "value" for each of the items in the second list. Cheers Dan. Code: <html>

hi again hi i want to create a form Form have 2 submit buttons also have one drop down list when selecting dropdown list item disable the one submit button plzzzzzz help m for do this with sample code needed. Hello all, I am having a problem, and since I am quite new in the Javascript code I hope somebody can help me here. This is my current code: Code: <select class="Form" name="opties"> <option value="AAA">AAA</option> <option value="BBB">BBB</option> <option value="SLX" selected>Selecteer optie</option> </select> Now my intention is the following: When the option with value SLX gets selected it needs to get a special css style. It is not a problem to give the option this style in the list itself, but once selected it always changes to the original style (standard font and color) in Chrome and Mozilla. Now I searched on the net and sometimes I find things like this: Code: function displayOption(divName)
{
document.getElementById(divName).innerText=document.form1.select1.options[document.form1.select1.selectedIndex].value;
}
<select class="Form" name="opties" onChange="displayOption('div1');">
<option value="AAA">AAA</option>
<option value="BBB">BBB</option>
<option value="SLX" selected>Selecteer optie</option>
</select>
But I suppose this always changes the style of the selected item? It only needs to change when the option SLX is chosen... Anyone knows how to solve this problem? |
