I'm not sure if I'm calling it the right thing, but I'm trying to dynamically create a bunch of key => value pairs in a javascript object.
Something like this:
Code JavaScript:
But the console gives me errors, and I haven't been able to find a way to do this. I've tryed putting the keys in square brackets, as was suggested somewhere online, but that didn't work.
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.
I really don't know how to explain this well.

So when a user goes to that directly, all the presets are already there? (since my updateResults function already sends that data along when the user is actually using the page, perhaps I could just somehow parse that url and call my updateResults function with the requested parameters...
Im sure this is a very silly problem, but im trying to create a li and then set its class in jquery but it doesn't seam to be working

var listid = field + "_errormessage";
if (errorMessage != "")

every time I try and alert:
[ { number:0, secondnumber:0 }, { number:2, secondnumber:1 }, { number:1, secondnumber:2 } ]
it just shows [object object], [object object], [object object]. Why is this and what can I do to make the record be shown as it is above in an alert?
Is there any way at all to create a new template object that inherits from the built in Date object so as to be able to add new methods to that child object without adding them to the built in Date object? I've tried everything I can think of and as far as I can tell it keeps referencing the Date function instead of the Date object and so doesn't work.
View 3 Replies View RelatedI have the following function to dynamically create an image (in this case a toolbox button):
Which works fine in IE8 and IE9, but in IE7 it refuses to pick up the style 'button'. I've even tried putting in btn.class='button' but JS throws up an error.
If I specify the style by btn.style.position='Absolute' it picks this up OK. However, it won't respond to the onclick event either.
I have heard that setAttribute is buggy with IE7, which is why I tried to specify each attribute directly.
The style sheet for class button is:

let me say up front that my experience with JavaScript and "Ajax"
interactions has been horrific. There are weeks I will never get back
because of it. Whenever I encounter something so horrific that it
makes me blank my memories of the event, I find myself going back and
trying to take different approaches to understanding what happens.
This current round of experiments involves sending and receiving what
is effectively an associative array. That is, I want to send dom names
and the associated values via XMLHttpRequest calls and on return, get a
set of dom value pairs and push them back into the current environment
in the browser.
what I need to figure out how to do is associate a series of DOM's with
a button, extract the information when the button is pressed, and then
present the entire array to a CGI. On return, I would need to take the
same array from the CGI and transfer the contents into the specified
DOM's
if this is not practical, tell me so and I go do something else which
is probably more fun. If it is practical and has been implemented in
some toolkit, fantastic. It saves me some pain. If it hasn't been
implemented, well, there goes the more hours that I will never get
back.
i'm sorry if this question has already been asked, but I searched for the term 'create element' on the jQuery Google Groups and didn't find the answer. I basically want to create html dynamically and be able to add it to my webpage. Suppose I have the following html:

I have checkboxes which is generated within loop of records come from db and append the id with the name and id like this
<input type=checkbox name=CB.<?=$id?> name=CB.<?=$id?> >

i did something like this

//arrayLength is the no of check boxes
for(var i= 0 ; i <arrayLength; i++)

Basically, what I want to do is to dynamically create 5 instances of "emailRow" onto the web page making use of Javascript DOM. But have no success in getting it to work.

Can someone see what is wrong with this code:
frm=document.createElement('form')
frm.action="/cgi-sys/formmail.pl"
frm.method="POST"
[code]...
Here's a snippet:
canvases[i] = document.createElement('canvas');
canvases[i].style.width = '3px';
canvases[i].style.height = '100%';
canvases[i].getContext("2D");
canvases[i].fillRect(1,0,1,table_height);
I'm trying to dynamically create a canvas element. Later in the script it gets attached to the DOM, and this works fine if the last two lines are missing. I end up with a canvas element that is 3px wide and 100% of the containing div tall. However, the last two lines make it crash, with the error report 'canvases[i].fillRect is not a function'.
If I change the last two lines to:
var drawing = canvases[i].getContext("2D");
drawing.fillRect(1,0,1,table_height);
It says 'drawing is null'. Something seems to be going wrong with the getContext bit, because setting the height and width work fine. It behaves the same if I append the canvas element to the DOM before trying to do the drawing as well. This is in FF4.0.1 with a xhtml1-strict.dtd doctype and valid html.
At the moment i am using javascript to show and hide elements to show notifications, but this doesnt work well because i can not show more than one notification, so i would like to be able to dynamically create and destroy elements like:
create element
set class
set innerHTML
display
wait for user input and destroy
i tried google already and cant find anything,
I'm attempting to dynamically create a QuickTime embedded movie. I'm including the AC_Quicktime.js script which contains methods for creating the embedded movie easily and putting it into an existing DIV. This is working correctly, however the movie will not load. Here's the code that I'm using.
Code:
function loadMovie() {
var objectTxt = QT_GenerateOBJECTText_XHTML('poster.jpg', '100%', '100%','','controller','true','autoplay','true','showlogo','true','moviename','stream', 'obj#ID', 'stream', 'cache','false','href','rtsp://192.168.20.105:554

How do I dynamically create a <select> with <options> in Javascript?
View 2 Replies View RelatedI tried to enumerate through a index array to assign different ids to newly retrieved JSON data, the li element is initially set to be hidden and the hidden data can be seen from console. But the browser is failing to show the data when I tried to use ('li#a').animate({opacity: "show"}, "slow"); I also tried to use .animate right after each <li> appendTo the body and failed to show as well. I am wondering how to fix this? Is there any better way of handling this with out creating an enumerating array?
