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?
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.
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?
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:
I 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; for(var j=0;j<chC.length;j++){ if(chC[j].nodeType==3){ txt[i]+=chC[j].data; } } allC[i]=allC[i].childNodes; } } alert(txt[1]) } onload=checkCell; </script>
I have a script that automatically makes the class change for an input field onFocus. Everything works in both IE and Firefox with the inputs, but I am having trouble with an image inside of a link in Firefox. I am using a link instead of a input type="submit" for IE reasons. Code:
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?
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.
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;
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.
I am running a bit of JS to highlight text inputs onFocus in IE. It seems to be working on all of the forms on the site except one. The debug code in the script displays the number of input elements in an alert. On the page where it does not work, the alert is "[object]".
Here is the script:
function initHighlight() { if (!document.getElementsByTagName){ return; } var allfields = document.getElementsByTagName("input"); alert (allfields.length); // debug for (var i=0; i<allfields.length; i++){ var field = allfields[i]; var attr = field.getAttribute("type"); if (attr == "text" || attr == "password") { field.onfocus = function () { this.className = 'highlightActiveField' } field.onblur = function () {this.className = 'highlightInactiveField'} } } }
function addLoadEvent(func) { var oldonload = window.onload; if (typeof window.onload != 'function'){ window.onload = func; } else { window.onload = function() { oldonload(); func(); } } }
var isIE = navigator.appName.indexOf("Microsoft") != -1; if (isIE) { addLoadEvent(initHighlight); }
Unfortunately, I cannot reveal the URL of the page (contractural restrictions).
Under what conditions would IE believe that the length of input fields is an object, not a number? I have run the page through two different validators and there are no errors.
I have a standard ul list where I need to keep count of the li's within (users can add/remove). This is my function when they remove a list item (.remove is inside the li), it removes the li fine but I always get zero for the rows.
I want to add some length validaitons to this form so that the state is enterted two characters long, the zip is entered five charaters long and the phone number will be entered eight characters long. Code:
The following function takes three different fields (which combined make up a phone number) and tests it to make sure that all the characters entered are integers. If this is true, it sets form.Phone.value = entirephonenumber. I would like to incorporate an additional test which, after determining that all characters in the string are integers, checks to make sure that the string length is 10. If it is less than 10 or more, I want the entire function to return false and display an error message (the same one is fine..) Code:
I'm attempting to run some checks on an input value. Initial HTML:[code]After the page loads a javascript calendar function called JDPicker runs and changes it to:[code] my issue only occurs on this HTML that is hard coded into the page. I have several other inputs (same element structure with the divs, etc) added later with javascript using createElement functions and my javascript works fine on those:[code]My problem is only in IE (testing with v 8). When I try to get the child elements value it gives me this error: "value null or is not an object". I tried using .nodeValue after that and it worked, but then started giving me errors regarding the .length function "length null or is not an object".
I want to know the length in pixels of a document embedded in a iframe. The way I go seems to work under IE but not under Firefox (about other browsers I'll see later). Code:
I have added two numbers from two table cells together using parseInt & innerHTML. I have this stored in a variable. I want to get the length of this number. I need to convert it to a string variable using toString and then access its length method. Whats the best way of doing this? I tried using toString then length but I am only getting "object window"!
I have a textarea field that is validated by Js, this textarea can and will contain the newline character so I validate in JS if(textareaname.value.length < 200)this hten goes through to my php where i also check before I place in to the Database using MYSQL,if( strlen($_POST['textareaname']) < 200 )but my php is giving me a different string length from my javascript.It looks as if Javascript is counting a newline as 1 character and php is treating it as 2.I have checked my slashes, I have used various REgex to check these data amounts. I have also Googled around and there doesnt seem much around.how I can make php and javascript treat a newline as the same amount of characters?
