JQuery :: ReplaceWith Not Replacing All Nodes?Oct 20, 2010
I have the following HTML:
I have the following HTML:
I've been searching the web for a while now, and I haven't come across a conclusive solution for memory leaks due to replacing nodes with frequent AJAX updates. I wrote a class that pulls an RSS feed frequently (e.g. every 5 seconds) and updates an HTML element with new information. In the process, it removes the old nodes and replaces them with new ones. It works fine visually. The only problem is that it has terrible memory leak complications; when I put the script on to run, it increases the memory usage by about 1MB every few seconds at an accelerated 1000-ms delay between updates!
(That's 100MB every few minutes!) I discovered this when I let the script run for a few hours straight, not thinking anything of it, and when I returned to my computer, it was frozen up Opera seems to be the worst at its memory management on this script, Safari and Chrome are in the middle, and Firefox seems to handle it the best, but nonetheless there are memory leaks in all four. (I haven't tested IE yet, but based on what I read, I would expect that it might even be worse than Opera!)
What's the best way to wrap all the nodes between two nodes in DIV tags? Is it possible with the DOM? I have code similar to the following:
How can I achieve this with the DOM, without resorting to doing something like a string replace?
Consider following html code
<a id="oliver1" href="/oliver1/">Oliver Twist 1</a>
<a id="oliver2" href="/oliver2/">Oliver Twist 2</a>
<a id="oliver3" href="/oliver3/">Oliver Twist 3</a>
<a id="oliver4" href="/oliver4/">Oliver Twist 4</a>
Why are anchor nodes pointing to href and text nodes pointing to [object]? As anchor and text both are objects therefore all outputs from indices 0 to 7 should be [object].
I'm trying to shrink some jQuery code by using replaceWith, instead of hiding and showing two different items. Since I'd never used replaceWith before, I created a test page, all it has has a div container, with class "one", and inside it the word One.
The jQuery code I wrote is below, it works to replace One with Two, when one is clicked. But clicking Two does nothing. I put in an alert to test what replacement is, and it is correct, a div with class of two. Yet still the second click doesn't return to One.
I've been using jQuery for a while now but I never needed to write something from scratch up until now. Is it possible to use some if statements to replace (replaceWith()) a form depending on which of the inputs was activated? The objective is to design a quick survey tool with different forthcoming questions, depending on the ones given.View 28 Replies View Related

Trying to replace text in a different div on a focus and change it back on blur. The first replace works, however the second doesn't. If I just comment out the focus then the blur works.[code]View 1 Replies View Related
Not sure whether this is a bug, but is is certainly unexpected behaviour. When i try to use replaceWith on a <div /> instead of a <div></div> (which is correct HTML syntax) it causes, not only the div but all code after the div to be replaced. see the code here: [URL] I will make a bug report if others also think this is a bug.View 2 Replies View Related
How do I replace main1 with a an external file?
I have the following HTML:
<div class="content"><button class="showalert">Show Alert</button></div>
<button class="blaat">Test button</button>
With this jQuery code:
$('.showalert').replaceWith('<button class="showalert" name="test">Show NewAlert</button>');
I'm using jQuery to created a linked TOC that appears in a dialog box. The function I wrote to do so finds all the h4's in the page and
I'm trying to remove an option in a dropdown menu so it's default is not Select. I'm using jquery-latest.js.This is the html:
<td class="column_main" align="center"><b>Size</b><br>[code].....
It doesn't seem to be working. When I do it without an attribute it replaces the lot of options which isn't what I'm after.
I've got an image for the Name & Email field in a form I've made. On click, I've got the images fade out, and replaced with the text field. The problem I have, is having the cursor go in the text field. I know it works if the text field was there when I click on it, but because clicking causes an event to put it in, it does't act like I clicked on the text field. So what I'm looking to do is at the end of the replaceWith(#name_field), I want it to simulate a click so that the cursor would automatically be in there.
Here is my js...
I'm utilizing the replaceWith(); function on a page to simply replace content in one area with new content with corresponding buttons.
Problem is I really want to have slimbox on my images that I am loading into this new area, and the links will not work. Oddly enough the code recognized that it is a link, it just won't play the slimbox animation, it just opens the image normally.
The code I have in a function file linked from the main page (portfolio.html) is:
$('#descrip').replaceWith ('<div id="descrip"><div class="floatRightPortfolio"><h4><em>"Embrace your Environment"</em></h4><p class="right"><a href="portfolio/embrace.html" rel="lightbox" title="Embrace Your Environment"><img
So basically there's a descriptive area on the right hand side, and the buttons are on the left. Inside the descriptive area is the title, and then the image.

I have a jquery script converting a XML file into html and part of the script is set to display an image based on the value in one of the elements. It's almost working as planned except that it affecting the preceeding record instead of the record that meets the conditions of the if/else statement.[code]View 2 Replies View Related

I am working on a site that has an acronym in the content that require a registered trademark symbol. This content is added via a CMS. I am currently having problems with the special character sticking when entered via the CMS textfield (it turns into a ? if the CMS page is edited and resaved), which brings me to my question:I would like to just enter the basic acronym via the CMS, like so: ACRONYM and then use the JQuery .replaceWith feathure to add the registered trademark to the ACRONYM dynamically so it will return: ACRONYM ® in place of all instances of ACRONYM that exist within a container div that has a lot of other content like so.I tried the following example and it worked in my webpage, but when I tried to change the code to replace just a text string instead of the p tag it did not work. I did not see an example of this in the documentation. So is this possible with .replaceWith and how would I fashion the code to look for the ACRONYM only? or is there some other method that is better suited fro what I am trying to do?

I've set up two buttons to dynamically load in content. However for some reason the content only loads on the first time you click a button. The transition function does receive the correct variables however. The fade0ut animation also doesn't take affect whilst the replaceWith() function is inside the transition function.
I'm sure I'm missing something basic, but I can't seem to find what I'm looking for. If I have an xml doc where the parent node and child nodes contain elements with the same name ("name" in this case), how would I go about just getting the client's name? Here is a slimmed down version of the structure:
I have the following code:
// The DOM (document object model) is constructed
I'm using jquery file tree and was wondering if anyone knew how one would go about expanding the first nodes upon load?[URL]...View 1 Replies View Related
I'm grabbing an XML file with jQuery like this:
Is there a way to print out the structure of a jQuery xml element...heres some code
This is the first question I couldn't find answered by Google! No doubt the answer is out there, but...
So I have a function that is being passed an array of nodes: some of them plain vanilla DOM nodes, (say, those created by document.createElement), others are jQuery nodes (say $("<div></div>").
What's the best way to determine if a node is of each type? I can obviously look at the node contents, but I wondered if there was a "best practices" here?
