Remove Textnode After It Is Created From The Array
Mar 17, 2006
I have created an array that holds three textmessages, how can I
remove the created textNode and feed the next message in line? Is
there also an issue with cleaning any whitespace too?
A code snippet:
----------------------
var altTextBanners = new Array(
"myText1",
"myText2",
"myText3");
altTextBanners.currentIndex = -1;
function initRotate() {
if (!document.getElementById) return;
altTextBanners.currentIndex++;
var text = document.createTextNode(altTextBanners[altTextBanners.currentIndex]);
var message = document.getElementById("message");
message.appendChild(text);
// how to remove the created TextNode and get the next one in the array
// ... ??
}
I have a "hard-wired" html div which encloses a button. Clicking the button causes the execution of a JS which successfully creates another div which encloses a button. The onclick attribute of the second button points to a JS which is supposed to remove the second div, the second div is not removed. I am using Firefox Deer Park Alpha 2 on an iMac 10.3.9.
Assume for the moment that I have not made a mistake in any of the code. Is it possible that a div cannot remove itself?
I'm trying to remove an element that was created after the DOM was loaded using append().
I append the element to a div when the checkbox is checked. But if this checkbox is then unchecked I want to remove the element, but couldn't figure it out thus far.
So I have a table with rows and basically I cloned it and then appended it underneath another table. The user can click on the plus button to clone the table (which on the UI looks just like a row of fields) over and over. Next to the plus button I have a minus button that I want to use to remove the cloned table. Here's my code for the add table button:
Basically what I need to do is write functionality for the remove button that when clicked removes the bottom most table. Is there functionality in jquery where you can say "find last occurrence of 'addrow' and remove it onclick"? [code]...
What I'm wondering is if the '.elements[i]' part of the above function automatically refers to the array created by the form. I didn't know that forms could automatically be referred by the elements dom without having a name or an id assigned to it. Does a form, when created, automatically assign its values/buttons into an array that can be referred by DOM?
I am running through a MySQL database using PHP and extracting all of the makes of cars in that database and trying to create a JavaScript array named after each make. Then I am trying to fill each array will all of the models for that make. When I just try to display each Make and Model in an alert box it seems to come up right. And my arrays seem to be getting created but they won't populate with the models (even though my alert msg shows the loops and everything is working).
PHP Code:
while ($row = mysql_fetch_array($result)) { $i=0; //Used so each model is added to the array starting at 0 and ++ $make = $row['make'];//PHP var used to extract data from MySQL

Haven't used JavaScript since a college class a couple of years ago and haven't used it in the real world for even longer. Never with PHP like this. But I am working on this marketing site and need to be able to list products by type according to each brand and as they can be added to a MySQL database it needs to be dynamic. I have the whole thing working by stepping through separate pages using PHP to populate select fields with the data but I want to be able to dynamically add the content to select field using JavaScript so it can all be done on one page and thought that if I could create these arrays on page load then the right information could be selected client side.
I am dynamically creating page elements by looping through an array and adding them to the DOM. Each element has an action that should be performed when it is clicked. This action (or a reference to it) determined by the current array value as well. Because the code called in the onclick handler is not executed until the event fires, the value of the current array item (at the time the onclick handler is attached) is not preserved resulting in the expected behavior not happening.Here is an extremely simplified example of the problem I'm facing:
Code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
I have a form on a page that has several textareas, and textboxes inside a table (so the table containing the textboxes is also inside the FORM tag).
I want to replace the textareas with simple text instead. But I want to keep the format of my page EXACTLY the same. However, the problem is that ...
1) Javascript won't let me create say a one-cell TABLE containing some text (e.g. textarea's value) and then insertBefore an element in the form. This is so because the a TABLE element is not compatible to be a FORM's child.
2) I surely can insert a text node or a table using appendChild or insertBefore on document.body. However, like I said I must maintain the formatting of my page, so I again can not do this. Reason being that the document.body won't have access to anything that's inside the FORM tag and can only insert before or after the FORM tag.
e.g.
<BODY> <P id="para1">foo</P> <FORM id=form1"> <!-- anything in here is Form's property NOT body's --> <input type="text" name="name" id="txtbox1"> </FORM> </BODY>
So the following code is invalid:
var tNode = document.createTextNode ("hello"); document.body.insertBefore (tNode, document.forms[0].getElementsByTagName ("txtbox1"));
because I can't insert a textnode before a form element using a body method.
And following code is valid but not what I want according to my second point above:
var tNode = document.createTextNode ("hello"); document.body.appendChild (tNode);
How can I insert a text node or table containing text inside FORM tags?
I found this plugin for converting xml to json which I need for myapplication at least temporarily until the server can get me JSONdirectly. The jQuery Plugin to convert xml to json works pretty goodit seems but i've found a bug.I have a structure that looks like something this:
When i click once on a button, i create one picture on the fly. And so on. It works ok. Then, using livequery, when i click on one of the all created pictures, i would like to see it removed. But it appears that only the first pic is removed (since all have the same name). What is my mistake ?
I have the following code which will split the given input based on the comma(,) and will store each value in separate address of the same array.[code]...
How can we remove the empty values while displaying the output or how we can remove the spaces from array+
I wonder if there any better method to check if the element in array B exists in array A, then remove it from array A. Code: var arrA = ['a','b','c','d','e'] var arrB = ['c']; I copied and modified this code from somewhere I got it online, but not sure if I understand it as it has two for-loops in it...
Code: for(var i=0;i<arrA.length;i++) { for(var j=0;j<arrB.length;j++) { if(arrB[j] == arrA[i]) { var index = arrA.indexOf(arrA[i]); }}} code to remove element from array A,
I am trying to accomplish a fairly basic task with javascript > my lack of Js knowledge has meant i have hit something of a roadblock.I need the a function to take an array from a form, remove the parsed variable from it and repost the form with the new array.This is what I have so far...
<script language="javascript"> function remove(SID) { var speakers = document.form_name.elements["SID[]"];
I'm trying to figure out how I replaces/removes parts of text in string in realtime using jQuery. This is what I got now:
PHP Code: $str = 'This is a <b>test</b>. Its not going well!'; echo '<div class="element">'; echo '<span>'.$str.'</span>'; echo '</div>'; echo '<p>Remove</p>'; Code JavaScript: $('p').click(function() { $('.element span').each(function() { var test = array('<b>','</b>','well'); //var test = 'not'; console.log($(this).text()); var text = $(this).text().replace(test, ''); $(this).text(text); }); });
The problem: As above nothing happens. If I use the var test = 'not'; instead of the array part it works except it also removes the <b> tags? How do I get the array part to work and why is it removing htmltags when executed?
HTML UL I have ul inside ul but all I want to get when I select a certain list is the children of that list but remove the ul inside that list so they dont show at all [URL]
