I am new to Javascript. I copied this script from the web, but I get an error at this line:parent.removeChild(child);The error says "Invalid argument".
<div id="parent" align=center>
<form name=mainfrm method=post>
<script language="JavaScript">

i have got about 50 definition lists on one html-page witch all look linke this:
<dl>
<dt class="title">aaa</dt>
<dd class="subtitle">bbb</dd>
<dd class="city">ccc</dd>
<dd class="email">ddd</dd>
<dd class="website">eee</dd>
<dd class="description">fff</dd>
</dl>
if the dt-element in one of the definition lists has a specific css-property (e.g. length > 100px) then the dd-element with the css-class "subtitle" in the same definition list should be removed.
why I am getting Nan
<script type="text/javascript">

var num2;
var num3;

Sorry this will be an ignorant question I know, but I'm just trying to implement some quick JS in my form to check if the fields were filled in:
function check_form() {
if (survey.form_firstname.value == "") {
firstname_error = "-Please enter your first name
";
}
if (survey.form_lastname.value == "") {
lastname_error = "-Please enter your last name
";
}
if (survey.form_phone.value == "") {
phone_error = "-Please enter your phone number
";
}
if (survey.form_email.value == "") {
email_error = "-Please enter your email
";
}
if (!survey.form_agree.checked) {
agree_error = "-You must be over 18 and provide accurate information
";
}
errors = firstname_error + lastname_error + phone_error + email_error + agree_error;
if(!errors) {
return true;
} else {
alert("There were errors:
" + errors);
delete firstname_error;
delete lastname_error;
delete phone_error;
delete email_error;
delete agree_error;
delete errors;
return false;
}
}
It only seems to work if no values are filled in, if one of the fields is filled in the error checking fails. Again, I'm extremely new to JS, i've only ever copy/pasted and this is the first time i've tried writing a piece.

I know I have a simple syntax error. Trying to call a function which changes the style of a div element on mouseover. Heres my code.
Javascript
function countermarker1(){
var box1 = document.getElementById('countermarker1box').style.display
box1 = "block" }
Variable is used cause I will have to use it more often later in the script.
HTML
<div id="countermarker1">
<img src="countermarker.jpg" width="20" height="14"
onmouseover = "countermarker1()"; /></div>
CSS (know its not really relevant just to avoid questions about whether its right)
#countermarker1box {
height: auto;
width: 80px;
display: none;
}
JS and css is externally srced.
I have written the following javascript code which makes a simple calculation and writes between the <span> tags using Inner HTML

I have a VERY simple script to reload a page with fresh values when the value of a scroll menu changes. Trouble is, of course, NN 4.- freaks and closes the browser when this runs. No error warning, no error log?
The line..
<select name="Country" size="1" onChange="repopmenu(this,17)">
The script..
<script language="JavaScript">
<!--
function repopmenu(which,key)
{
n = which.value;
var url = ("eventedit.asp?country=" + n + "&key=" + key)
location.href = url;
}
//-->

$('li').remove('input');

I was trying to create JavaScript error handling for a form, and I was trying to get an error message to show up underneath the field where there was an error. (I am trying to avoid alert boxes.) I only have two fields, and my problem is that only one field is showing an error message. If I place an error in the input for the second field, the error shows up under the first field. How can I get the error messages to show up under the correct form field?
Code:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "[URL]">
<html xmlns="[URL]">
<head>
<meta http-equiv="Content-type" content="text/html;charset=UTF-8" />

.qty {

text-align: right;
}.blank {
display: none;
} .....
I'm using this plugin in its simplest form.. [URL] All I have is this for my code:
<script>
$(document).ready(function(){
$("#form").validate();
});
</script>
It works fine, but I'm trying to hide the error messages which it defaults to "This field is required." The error message shows up in a label.. How in the world do I hide those error messages within those labels?
I use the below code to add or remove a row from a table using javascript. The code works fine on IE however it doesnt work on Firefox, can anybody suggest reasons why this might be doing so?
The id "table1" is the ID of the table I am trying to insert the innerhtml into.
function addRoom()
{
var row = document.all("table1").insertRow();
var column = row.insertCell();
column.innerHTML = "input type='text' name=txt1>";

Here is my link [URL]. First you need to a simple route name and then press the submit button and do not select the select input values. Then you will see red message appear below it. Now my only problem when I have selected meaning on change I want the error message to disappear.

I am having a problem removing an element after adding it.
This removeElement funcrtion works in IE but not in FF code...
I put this at the end of my code thinking that after the div displays (id = 'link_container') I can eliminate (id = 'link_container') from memory when the script ends so there's a place for another div (id = 'link_container') when/if there's onkeyup event. Wouldn't this little script remove any element with an id = 'link_container' ?
<script type="text/javascript">
var deleteDiv = document.getElementById('link_container');
document.body.removeChild(deleteDiv);

I've got a default value of some text in an input element when a page loads.
What I'd like to do is have the value disappear when the user clicks in the
input field.
I've figured out I can use:
onclick="this.value=''"
This works fine, however if for some reason the user adds his own input,
then click somewhere else/clicks back, the text has once again been erased.
So I thought of a function like the following, however it does not work:
function removeinput(x) {
if (x == 'Enter items not on standard list here...') {
x = ''
}
}
onclick="removeinput(this.value);"
I've also tried placing this.value inside of single quotes to no avail.
I have some problems with removing <li> element by clicking on <a href=""> element in it.
For example:
<ul id="menuList">
<li><input type="text" class="title"/> <input type="text" class="block" /><a class="delete" href="#">Delete</a><li/>
<li> <input type="text" class="title"/> <input type="text" class="block" /> <a class="delete" href="#">Delete</a><li/>
[Code]...
It checks all <li> elements and save value of title and block input fields in array of objects ang generate JSON - code and input it into #code element.But when I delete one of the <li> by clicking the link, it becomes invisible for me, but function ParseMenu save it into array whatever/ What can I delete this <li> element from everywhere?
I appended an a and select tag inside a div.
When a checkbox is checked it will append these items. Yet, now I want it where if it's not checked or the person unchecks it... then it will remove the appended elements.
How can I do this?
This is the code I have so far:
if($('input[name="hosting_Service"]').not(":checked")){
$("#hosting_text").remove();
$("#hosting_options").remove();
}
This is inside a php echo.. so don't mind the " " it's just saying it's " "
according to the code... I check with a if statement if true and remove the elements. the condition is when the checkbox is not checked. I have the same exact code to append the elements inside the div. but instead I used the .is instead of .not the hosting_Service is the input that is a checkbox.
however this code seems to work.. only for hosting_options. yet, it breaks all the code... meaning I have the if statement before this checking if it is checked... then append the elements.
well if I add the code above it dosen't allow when you check the box to append the elements inside a div.Yet if I didn't add this code and then click the checkbox it will append the elements but without refreshing the page.. if I then add this code given to above the hosting_options would only be removed and the hosting_text will still not be removed.
I was both to work properly. I want it where if you click the check box to mark it... it should append elements into the div. If you uncheck it then it should remove those elements that were appended.
