if I have:
<form id='form1'>
<input id='one' value=''>
<input id='two' value=''>
</form>
is there a way for me to check the child nodes of the <form> element for a specific id. in other words, can I check if form1 contains an element with id 'one' for example?
this should be simple but I cannot figure it out. This is the HTML:
HTML Code:
<div id="box">
<p>one</p>
<p>two <strong>three</strong></p>
...
</div>
The JavaScript function has to take everything inside <div id="box"> and put it into another div. It should become:
HTML Code:
<div id="box">
<div class="content">
<p>one</p>
<p>two <strong>three</strong></p>
...
</div>
</div>
So how can I get all childNodes recursively to enclose them with another element?
I have a problem with getting the amount of childs in a XML structure,
the strucure is somewhat like the following:
<?xml version="1.0" encoding="iso-8859-1"?>
<cms>
<num>21</num>
<xmlnames>
<field>id</field>
<field>name</field>
<field>availablefrom</field>
<field>availableuntill</field>
<field>owner</field>
</xmlnames>
</cms>
If I use the following to get te amount of childs for xmlnames I get an
amount of 11:
xmlObj.responseXML.getElementsByTagName('xmlnames' )[0].childNodes.length
Is this wrong or maybe there is a better / other way of counting the
child amount?
I am starting to learn using javascript on DOM. One of the first things
I tested was listing all the child nodes from an element. Like ->
*html code:
<div id="pagetitle">
<span>My Text</span>
</div>
In my javascript I tried to list all the child nodes from <div>, Firefox
and Opera gave me 3 -- 1)text node with a null value, 2)span, 3)text
node with a null value.
It look to me that the browsers treated the line break as a text node
with no value!!
If I modified the html code to :
<div id="pagetitle"><span>My Text</span></div>
Then the browsers gave me the right answer: 1
They still gave me a wrong answer of 3 if I put a space around the
<spanelement like this:
<div id="pagetitle"<span>My Text</span</div>
What did I do wrong? I would still want the elements to be on their own
lines.
i wrote a very simple HTML page to test some DOM features between Mozilla and IE. Mozilla is perfect everything went fine and i got the childNodes from my custom tag ( this tag i named <blah> ), inside this tag there is two <span>, that i retrieved. But with IE i really could figure out how its done! Code:
View 1 Replies View RelatedI wanna get all the text nodes of the children of an element. The goal is to get an array with all the textNodes in each cell of a table, without any other nodes that might ocure whithin that cell (<p>, <br> etc...)
I mean if:
<td>12</td>
<td>1<p>23<b>34</b>5</p>6</td>
I need:
var txt = new Array()
txt[0] = ཈'
txt[1] = ?'
Now I had to circle through all the childNodes to extract all the text nodes. I have build a function, but something is wrong in the code, and I don't sense what. I need soime fresh eyes, any ideeas? Where's the mistake?:
<script type="text/javascript">
function checkCell(){
var allC = document.getElementById('tab').getElementsByTagName('td');//cells' collection
var txt = new Array()
for(var i=0;i<allC.length;i++){
txt[i]=''
while(allC[i].hasChildNodes()){
var chC = allC[i].childNodes;

allC[i]=allC[i].childNodes;
}
}
alert(txt[1])

I have a javascript for a tree view but i need to change it according to the requirement. Lets start with example with the treeview as follow:
1 Door phone
1.1 Ready Kits
1.1.1 Audioset
1.1.2 Videoset
[Code]....
Now the thing is in the current treeview a single category is open at a time. like if 1.1.1 is open 1.1.2 will b closed and similarly if 1.1 is open...1.2 will b closed. But i want that when i click on 1(Door phone) ie Door phone...evry node should be opened instead of just one similary when i click on 2(CCTV), all its node should be opened.
From what I've read, everything in the DOM is a node. Basically there are three types of nodes: text, element and attribute (there are more node types but these are the most common).
Let's say I have the following html:
<html>
<form>
<p></p>
</form
</html>
Then this javascript:
var forms = document.getElementsByTagName("form")
var form = forms[0];
alert(form.childNodes.length); /* output is 3 */
I would think that the output should be 2 as I only see 2 childNodes for the form object: the <p> element is an element node and the <p> element has a text node, so that's a total of 2 nodes. Where is the 3rd one comming from.
To add to the confusion, if I change the html to:
<html>
<form>
<p title="jeff" id="22"></p>
</form
</html>
The above javascript still outputs 3. I would think that the output is 4:
- 1st node is the <p> element
- 2nd node is the <p> element's attribute node "title"
- 3rd node is the <p> element's attribute node "id"
- 4th node is the <p> element's text node
Obviously I'm not correctly comprehending how childNodes are determined.
I want to count the number of childnodes, when i run this script in mozilla i get a different total for the number of childnodes from numkids then when the script runs in IE. Why is this? How Can I get the same number. I want to loop though an objects child elements setting them to invisible or visible
<script type="text/javascript"><!--
function rec(n) {
var kids = n.childNodes;
var numkids = kids.length;
for(var i = numkids-1; i>=0; i--)
{
// sets child to hidden
alert(numkids);
alert(kids[i].nodeValue);
//kids[i].style.visibility = 'hidden'
}}
var a = document.getElementById('commentholder0');
// this function loops though the parts and makes then invisiable so you cant see them overlap
rec(a);
</script>
My html is here:
<ul id= "commentholder0" >
<li id="comment1">this is a test</li>
<li id="comment2">this 2 is a test</li>
</ul>
I need to find the length of the childNode "city" to a particular "region" in the below XML.

Example the Region is East it has 2 cities below. I need to get this length using JS.
I tried doing x=xmlDoc.getElementsByTagName("City").length;
But it counts all the city elements present i.e. it returns 4. How to get the length of the "City" element particular to a "Region" element.
i'm working on a portion of a CMS that allows content-admins to browse
a product list, and add individual products into the taxonomy by
clicking checkboxes next to categories they might belong in.
since the taxonomy is a rather long list, i'm hiding and showing divs
for the secondary and tertiary links, so when a user clicks on the
checkbox for the parent category, the children appear in a second (and
third) div, with checkboxes of their own.
however, i'd like for the secondary and third level checkboxes to
become unchecked when the parent is. i've tried addressing them in
numerous ways, but something consistently gets lost, in that i keep
getting "x doesn't have any properties" errors.
ie:
var parentnode = document.getElementById(divName);
var allMyChildren = parentnode.childNodes.getElementsByName("INPUT");
alert(allMyChildren.length);
this returns the proper length, but then
for (var i=0;i < allMyChildren.length;i++) {
var chklist = allMyChildren[i];
if (chklist.type == "checkbox") {
// uncheck it
}
}
this consistently returns that chklist has no properties...
Is there a way to calculate the .offsetLeft or .left of a character in a string relative the element that contains the string? I'm just trying to wrap each character in an element and position the characters independently, so I have to set the .position to absolute, and set the .left and .top on each element as I create it so I can move the elements later on.

View 10 Replies View RelatedHere is the HTML: [URL] I'm trying to uncheck the selected radio button, then set the value to 1 (Yes), basically overwriting theinitialvalue to 1. I've looked at prop(), val(), and attr(), and just don't know where to start. Should I select $('#set_q157 input') or$('#set_q157 input:radio'), or each individual radio?
Do I need to each them, and check if its checked, then change its value, or is there a way to select all three inputs as just one radial button? It would also need to work if the input has not yet been checked.
i have a list of checkboxes, the number of checkboxes is dynamic. All the checkboxes have same name. i am trying to get the length of selected checkboxes.
<input type=checkbox name=name1 value=1>
<input type=checkbox name=name1 value=2>
........ get dynamically.
when i try to get the length in javascript like document.form.name1.length, it works fine if number of checkboxes selected are more than 1, but not for 1.
I have a code that I got from a tutorial website. The goal is when someone clicks the first check box with the value of yes then the two other sets of check boxes will autmatically be checked for no.
The issue is their are three sets of 2 check boxes each.
So here is my code code I am trying to use
PHP Code:
Here is my form code
PHP Code:
So Ideally when a representative clicks that the customer has three services (clicks the Yes checkbox) all the other checkboxes will default to No.
How I would change the above javascript to do this.
I am a php programmer and not a Javascript programmer and I am trying to help a friend out with his shopping cart. The original programmer (who wrote this years ago and is no longer around) has a button that looks up the quantities in the database for the submitted items, and then displays a prompt if you selected a quantity that is less than the minimum purchase amount.The issue is if the user enters a smaller amount than allowed and hits the enter key instead of the "Buy" button, it allows the order.how to use the current code to also check for an Enter key submission.I can handle the PHP and the db lookup for minimum quantities. Here is the page code and the Javascript code.
Code:
<a href="javascript:checkQuantity(document.form<?php echo $formCount; ?>,
<?php echo $row_rsProduct['lotQty']; ?>,
[code]....
I have an .asp page for my customers which does just accepts e-mail information and passes this information to another .asp page. But before passing the info, a javascript checks whether the entered e-mail does match some certain rules. Rule1: If any input has been made at all, Rule2: If an "@" sign is there, if the"." is there and so on. upon pressing the submit button, the first rule works but the second rule does not. Could not figure it out why.
[Code]...
It is the function control() which validates the e-mail field. But it just validates whether the e-mail has been entered or not. The second check (with the @ sign) is not being made.
I'm working a bunch of pre existing code on a CMS. Just after a quick fix. Doing a show/hide thing on a particular div somewhere on the page depending if a checkbox is ticked or not.Currently there is 3 checkboxes that are dynamically added through the CMS. Here's simplified version of the form:
<form id="simplesearch" name="simplesearch">
<input type="checkbox" onclick='showhidefield(this.value)' name="meta_data_array_search_criteria[custom_profile_type][]" value="5" class="input-
[code]....
<input type="checkbox" id="priority" /><span class="presult">0 USD</span>
I want when checkbox is checked, the span will have 500 USD. When checkbox is unchecked the span will return 0.This is what I've got, have no idea why not work.
Code JavaScript:
if ($('#priority').is(':checked')) {
$('.presult').text('500 USD');
[code]......
i need to check to see if my check box is checked, here is my code...
echo "<form id='form1' name='form1' method='post' action='".$href."' onsubmit='return checked_room()'>";
while($row = mysql_fetch_assoc($res))
{
[Code]....
now for some reason i can't get the javascript to work within the function.
How can i select max 2 check box from 10 check box.following code i used for check box
PHP Code:
<input type='checkbox' name='r1[]' value="<?php echo $bno;?>"?>>
What code can be design in JS
Here is my function
<script language="javascript">
document.form.B1.disabled = true;
function changebutton(){
if (document.form.C1.value = "ON"){
document.form.B1.disabled = false;
return true;
}
else {
document.form.B1.disabled = true;
return true;
}
}
</script>
So far it's doing what I want it to do, when the document loads it disables
the button, and when the check value is clicked it would enable the button.
Now here is the problem, when I uncheck the checkbox the button is not
disabled.
Is there a way to check what the URL bar is = to? so if it was equal to [url] it would change something on the page?
