Dynamically Loading Link Elements Via DOM

Mar 16, 2006

I have a set of scripts which rely on the ability to dynamically load css by constructing <link> elements via DOM scripting, and appending them into the page header. It works, for the most part, extremely well, but I need to be able to attach an onload function to said links. Unfortunately, this only seems to work in IE, not in FireFox or Safari (the three being my 'target' browsers under which the whole system needs to work.) Any means by which I can determine via Javascript whether such a link has finished loading? It doesn't have to be via onload if it's unsupported, but I need to be able to implement it across IE / Mozilla / Safari.

Dynamically Loading External Javascript Files.

Apr 14, 2006

I have been struggling with a cross browser solution to loading
external javascript files on the fly.

I have been successful using the following code in IE6:

var newScr = document.createElement("SCRIPT");
newScr.src = "newScr.js";
newScr.type="text/javascript";
document.getElementsByTagName("head")[0].appendChild(newScr);

I believe the reason is that IE is loading the external file
syncronously while Firefox is not. Is there an onload event for
creating an element (if so I do not see it in Venkman). I have seen the
solution of using XMLHTTP to load the script but I am trying to get
around any dependency (atleast at this stage of the library) on
activex.

How To Abort Loading Of Dynamically Included <script>

Jan 4, 2007

I'm writing a small async webapp. in JavaScript and I'm using <script> element technique to load data. I'm usign <scriptbecause of cross domain restrictions with XmlRequest.

The problem is when I remove a element that is currently loading from DOM (with removeChild) Firefox still loads it and waits with other scripts.

What I want is to break this process and load a new data without waiting for old one.

Here is example script:

Loading Divs Dynamically -- How To Detect Which One Loaded Currently..

Jan 25, 2007

I'm using a function like this to load divs dynamically (and hide
current one..)

function get_img(curr_img,curr_nav,new_img,new_nav2) {
var img_top = eval('document.getElementById(' + "curr_img" + ')');
var img_new = eval('document.getElementById(' + "new_img" + ')');
var nav_top = eval('document.getElementById(' + "curr_nav" + ')');
var nav_new = eval('document.getElementById(' + "new_nav" + ')');
img_top.style.visibility = "hidden";
img_new.style.visibility = "visible";
nav_top.style.visibility = "hidden";
nav_new.style.visibility = "visible";
curr_img = new_img;
curr_nav = new_nav;
}

problem I always run into in situations like this is I can't tell which
one is currently loaded.. how do you detect which div is currently loaded?

this is in JSP, divs generated with loops...

for (int i = 0; i < photos.length; i++) {
%>
<div id="nav<%=photos[i]%>">

etc...

JQuery :: Dynamically Loading Source From A String Into The DOM

Aug 12, 2010

I'm experimenting with dynamic loading of javascript using JQuery. So basically I have a loadScript function that accepts either the URL of a JS file or a javascript source in a string. For the former, I create a 'script' element, set its src attribute to the URL of the file and insert the element into the DOM's head element. So far it seems to work nicely. For the latter, I create a 'script' element, set its innerHTML to the JS string and insert it into the DOM's head element. This doesn't work so well. I *think* it's because the JS source in question contains:

$(document).ready(function() {
// put all your jQuery goodness in here.
});

It looks like the JS source in my string is stomping over parts of the DOM it shouldn't and changing existing elements.

Dynamically Loading Files Containing Bunch Of Data

Apr 28, 2011

Here's what I'd like to do using pure JavaScript and HTML (no Ajax or PHP): My website loads different JavaScript files dynamically which contain a bunch of data, that I will display on the website. The dynamical loading function is placed in the <HEAD> and looks like that:

Code:
function loadJsFile(filename){
console.log("loading js file")
var fileref=document.createElement('script')
fileref.setAttribute("type","text/javascript")
fileref.setAttribute("src", filename)
fileref.onload = dataIsLoaded;
if (typeof fileref!="undefined"){
document.getElementsByTagName("head")[0].appendChild(fileref)
}}

The dataIsLoaded method in there is a callback that is triggered when the JavaScript file has been loaded:
Code:
function dataIsLoaded(){
console.log("loading js file done")
dataLoaded = true;
data = new Data();
}

DataLoaded is simply a global boolean that is per default false and the 'data' variable contains all the data I want to display on my site. While the JavaScript file is being loaded, the browser continues building the site. When it gets to the <body> that wants to access some information from the data variable, I get the unsurprising error that 'data' is undefined. I looked for a way to wait until 'data' is defined and then continue with building the <body> but couldn't find a solution.

Alternatively I wanted to reload the divs in the <body> when the 'data' is available:
Code:
function reloadDivs(){
if(dataLoaded){
console.log("data available, reloading divs");
document.getElementById('someDiv').innerHTML = document.getElementById('someDiv').innerHTML
}else{
console.log("data is not yet available");
setTimeout('loadReportData();', 500);
}}
This does not work, I get a blank div when I do that.

IE Never Finishes Loading Page When Dynamically Removing Images

Mar 30, 2006

While testing my pages in IE and Firefox, I have noticed that when I
remove an image from the DOM before it has finished downloading in IE,
that the status bar gets stuck at Downloading Picture https://....
Which means the page never finishes loading, I have tested by just
making the images style.display = "none" and I no longer get the error,
but since this is an AJAX app, that would just leak memory as images
would never get deleted when people traverse the web app. Has anyone
else experienced this behavior or have a possible solution?

Ajax :: Loading Link To A Div

Oct 10, 2010

Let's say my site is located in a folder named 'temp'. My index.php is in that folder and there is also a folder named 'common' where I've stored my .php files that I also load.

[Code]...

However, in whenever I click on a link (from the index.php that has main_menu.php included), it doesn't seem to work. Always getting the msg "There was a problem with your request"). Does it have to do with the fact that my pages are in .php? And if so, how can I modify my code to work with .php files?

Dynamically Add Elements With Javascript?

Nov 13, 2006

I'm adding people to a database. People have a first name, last name,
and a undetermined number of Cities and States with which they can be
associated. I've got a drop down box that I would like to use to
display the number of inputs to allow for city/state entry. I would
like to dynamically increase or decrease the inputs based on a user
changing the selection in the drop down box, without submitting the
script. Only the first city and state are required (which is why the
label is bold). Any ideas on the best way to handle this without
losing any potential city information that may have been previously
typed into the input (i.e. if I type San Fran into city0 and CA into
state0 and then change the number of cities to 4 - I'd like San Fran
and CA to still be populated in city0 and state0). Code:

JQuery :: Dynamic Loading - Create Portlets That Dynamically Load Their Content

May 29, 2009

I am trying to create portlets that dynamically load their content (usinq jQuery). My first approach was to leave the header + footer + decorations of the portlet OUTSIDE of the dynamically loadable content. It worked just fine but I had to abandon that approach so that I could use the same code both for statically- and dynamically-loaded content (e.g. when no AJAX support was available). So far so good.

Now to my problem: I use the following code for loading my dynamic content

The loading works fine, but after the dynamic content has been loaded I can not seem to get access to it using jQuery!

Short description: Line 3 clears the content (I know! There are better solutions!) Line 4 loads the content Line 6 dumps the data on the console; this is for debuging only, so that I can establish that the correct content is loaded

After the data is properly loaded I did expect to be able to find it by traversing the DOM tree in traditional jQuery fashion (like in Line 10). However, dumping the contents of the 'tag' shows it containing no content at all; it is empty even though the browser renders the expected new result. I thought: Well! The browser holds two copies of the DOM tree; one that is the original page and one that is the modified content used for rendering". Therefore I attempted to manipulate the loaded content within the function (Line 8). The content is visible there, that I have established in Line 6. But I do not know how to access it jQuery-style.

(Why am I trying to modify the loaded content? I want to inject a title row with various decorations and clickable content.)

Loading A Html File Into A Div From A Link?

Mar 28, 2009

i found a way to click a link and load it into a div. the only problem is that i keep getting the "AHA error" from the if statement in my div.

i'm not sure if it is me or the coding but i'll post what i'm using in jscript here:

function ahah(url, target) {
document.getElementById(target).innerHTML = ' Fetching data...';
if (window.XMLHttpRequest) {
req = new XMLHttpRequest();

JQuery :: Adding Div Elements Dynamically

Nov 10, 2011

I have the following bit of code:

<script>
jQuery(document).ready(function() {
var url='http://search.twitter.com/search.json?callback=?&q=test';
jQuery.getJSON(url,function(json){
jQuery.each(json.results,function(i,reviewa){

I'm baiscally trying to get some twitter feeds and the rotate them. I can get it and everything like that but for some reason the jQuery doesn't pick up the divs that I appended to the container because when I alert the div.length like this: alert(divs.length); The result is always zero. The code works fine if I can populate that value but if I don't have it in the code before hand it doesn't work. However if I add a div to the container like this:

Dynamically Add Elements (TextNode And DropDown Box)

Dec 15, 2009

This block for adding a text box works:
Code:
var secondCell = row.insertCell(1);
var el2 = document.createElement('input');
el2.type = 'text';
el2.name = 'ProjMemFName' + i;
el2.id = 'ProjMemFName' + i;
el2.size = 20;
el2.maxlength = 25;
secondCell.appendChild(el2);

But this block for adding a dropdown box isn't
Code:
var firstCell = row.insertCell(0);
var el1 = document.createElement('option');
t1=document.createTextNode("DBA");
el1.appendChild(t1);
el1.name = 'ProjMemTitle' + i;
el1.id = 'ProjMemTitle' + i;
el1.value = 'Team Mem #' + n;
el1.size = 20;
el1.maxlength = 20;
firstCell.appendChild(el1);

I get the TextNode, but not the dropdown box. I'm close, but trying to finish getting the syntax correct.

Accessing Dynamically Created Elements?

Dec 23, 2010

I'm trying to write a script for a website that reads from a database and makes a separate table for each entry in the database. Since the number of entries can change, I want to dynamically create a div for each one, which I can later hide or display based on user selection. However, when I try to access the dynamically created elements by their ID, they return null. Is what I'm trying to do here actually possible?

for(var i = 0; i < tables.length; i ++)
{
var newDiv = document.createElement("div");
newDiv.setAttribute("id", tables[i].name);
newDiv.setAttribute("name", tables[i].name);
newDiv.setAttribute("class", "hidden");

[Code]...

Dynamically Added Elements Cannot Be Removed

Oct 26, 2011

In my application I render a couple of elements dynamically after the user selects an option in a dropdown list. When the user selects another option in the dropdown, I want to remove all the previous elements that was added dynamically. I've tried with the .Remove() function, but it seems the elements cannot be found in the DOM. I've looked a lot at the .live() events.

JQuery :: Loading A Div By Id Based On Href Of Link?

Aug 23, 2011

I'm using the jmapping plugin and it's all working great - when you click on a location link in the side bar the map pans to the location. However what I also want to happen when I click the location link is to load more information about the location onto the page.The idea is to load the div from infodivs.aspx which has an id that matches the href of the link that was clicked. I can make the whole page load without issue but I can't get my head around the syntax for identifying the href of the clicked link and then inserting that into the load statement as a div id.I've tried this.href but if that's actually the right approach, I haven't phrased it right so farHere's the code:

$("a.map-link").click(function () { $('div#moreinfo').empty().load('infodivs.aspx what goes here?');
});

JQuery :: Loading A LightBox Link From Another Page?

Opening IFrame Link Loading Into Parent

Jul 22, 2011

I am having difficulty in opening a link in an Iframe. If I explain, I have four pages
-Page 1 containing the Iframe
-Page 2 containing a series of thumbnails that opens in Iframe on page 1
-Page 3 is the larger image that opens in the Iframe on page 1 after clicking the thumbnail on page 2
-Page 4 is a page with a linking menu that has a link to page 3

The task I am struggling with is to get the link on page 4 to open the larger image of page 3 in the Iframe on page 1. Now I maybe doing something wrong but the code is opening page 2 in the Iframe on page 1. Below are the links to the pages in question.
Page 1 Art for Sale - Bertram Enterprises
Page 2 Bertram Enterprises Collection_Ver2
Page 3 [URL]
Page 4 Jenni Dutton - Bertram Enterprises link near bottom of page - Art for Sale
I wish to use this on many more of the images.

JQuery :: Loading Files - Script Element Is Dynamically Added To The Head Section Of Html

Feb 6, 2010

I came up with some code to load javascript files dynamically. But I've got problems..

When the script element is dynamically added to the head section of html, i think that the document.ready event fires once again and therefore the code sort of runs twice.

In the html page I call this method:

In the script test.js I have the function SayHi():

The SayHi method never gets called and alert('begin') & alert('getScript') get called twice in this sequence:begin begin getScript getScript.
