Accessing GET And POST Vars Through The Dom?
Nov 23, 2005
I am doing this project. It is a flash app that the final output will open a borwser window. The flash app will send vars in the URL, ex/invoice.html?num=1&blablabla=blabla). In the HTML doc there will be a template invoice that I need to replace some of the content (prices) with the sent GET / POST vars.
It all needs to be client side that's why I need someone's javascript help. the app needs to be able to run without internet or any server side processing. so I figured some javascript would work.

Note: answers along the lines of 'use jquery' or 'use (insert wellknown framework)' is not helpful.Frameworks such as jquery includes alot of extra code which is not nessary at all for what I am doing. 'But, you can include one from Google', yes that may be the case, but I prefer to keep to my own code. With that in mind, lets proceed to the problem.
I have an ajax call which doesn't pass POST vars through on IE7/IE8, but only on odd occasions. It appears to be extremely random and the majority of the time it does work. I am had a look at jquery and cannot see much difference in the way it works compared to this custom one.

I have now a form inside a form which of course doesn't work. I need to have a way of getting specific field data without posting till the whole form is done.
For example,
the form contains several items but a specific section for part quantities allows the user to enter the quantity and then click on the "Add Part Nums" button to get a form in a popup that has entries for part numbers based on what the quantity was in the first form.
I have this part working perfectly but it's a form inside a form so it only works when I comment out the outer form tags.
Is there a way to submit the quantities fields only and get the pop up and then later submit the entire form? A way to do this without having a form tag for the inner part?

The below code posts a couple of vars to a php file which sends back a json object containing (in the test case) one object called 'faves' with 2 variables (let's say called var1 and var2). I can't seem to access the variables after the ajax call. The result is always an 'undefined' error message. I've tried:
console.log(data.var1)console.log(data.faves.var1)
console.log(var1)
All to no avail. Can anyone tell me what I'm doing wrong here? I have checked with FireBug that all the data returned is good and well-formed etc.
$(function() {
$.post("<? echo base_url(); ?>test.php", {
id: "<?php echo $id; ?>",

So I'm currently working on a ASP.NET Webforms site and I've run in to a small problem. On my .cs file I have the following Webmethod
[WebMethod]
public static string IsJobEditable(int jobid){
try{
string isEditable = "false";
JobsBLL jbl = new JobsBLL();
int jobStatusId = jbl.GetJobStatusId(jobid);
//If the jobs is either waiting or being edited it is
okay to edit it
if(jobStatusId ==
Convert.ToInt32(ConstantsUtil.JobStatus.Waiting) || jobStatusId ==
Convert.ToInt32(ConstantsUtil.JobStatus.Edit)){
isEditable = "true";
}return isEditable;
}catch (Exception ex){
throw ex;
}}
This function in this case will ALWAYS return TRUE as a string. On Aspx page I have the following
$(function () {
$.ajax({
type: "POST",
url: "Coordination.aspx/IsJobEditable",
data: "{jobid:" + jobid + "}",
contentType: "application/json; charset=utf-8",
dataType: "text",
success: function (result) {
alert(result);
//This is written out in the alert {"d":"true"}
I want this in a variable as a string so I can do a check on it before I do some other actions. The format is not a String so I cannot split on it to retrieve the "true" part.
},
error: function (err, result) { alert(err); }
});});
As you can see in the comments the value I get back in the Callback method is in to me a weird format. The type is unknown and I need this value to be able to proceed with my entire method surrounding the small portion of the Javascript. Where to access the result variable / data as a var or anything else that will let me put it into a var (as a string).

I have a two fold question:1) Why would my while statement not be workingI have cleaned up my code a little (although not perfect) but my while statement is not behaving, it does not output any numbers on a console.debug (using google chrome, or any other browser for that matter) which from my understanding it should?and 2) Slightly out of the remit of this forum I suppose, but this code is quite lengthy and I know there are ways to make this more efficient I just dont know what they are?

I'm struggling a bit with trying to make sure when I set an event handler (or listener) on some element which calls a function I've got elsewhere, that the function can't see necessary vars because they've already been garbage collected.I'm following the type of setup as in Simply Javascript or the Javascript Live course.o I have stuff like this

This sends variables to the page okay (on a version without the onClick, opening a normal page).
Problem seems when onClick is added: where the # would normally be following the url to open the popup from colors.htm
PHP Code:
if ($row_results['Mcolor']> 2) {echo'<a href="http://www.mysite.com/colors.htm?UsrID='.$row_results['UsrID'].'" class="linebar" onClick="MM_openBrWindow('../s/shades.php','','status=yes,scrollbars=yes,width=620,height=450')">more</a>';}Â
Is there always a conflict between javascript and php when sending vars since javascript is client side and php is server side? Is there another way to size the opened page, for instance, on... /shades.php itself? - Only doing the popup for this reason.
Inserted this in head of the destination page; shades.php itself, but not as a function. Might there be a way to activate this when the page loads, without onClick of a button from prior page?:
Code:
<script>
windowresize.To(400, 600);
</script>

How can I apply javascript validations and functions to dynamically generated form fields which can be 10, 20, or 30 in number?
I am creating dynamically generated form fields so there can be 10 or 20 or 30 and so on (in groups of 10, and up to 50)
I need to apply javascript validation to those fields.
My question is how can I predict the number of fields there will be?
I need to do things such as this:
If field1 = "Null", Set field2, 3, 4, 5 to "NULL"

I am creating a mp3 playlist player for a mobile page on my website. Got the music to play fine and everything the only thing I have left to do is get my page to display the timer for the running time for each song. The one problem I am running into is this....my phone and I'm sure many other phones/mobile devices support javascript, but not javascript functions. For example I can run a <body onload="setTimeout('blah',1000)"> function on my phone and anything in the body onload statement, if it's in javascript will run. However, refer to a function and the code won't work. Here is the code that will wok in a standard web browser with javascript support:PHP Code:
echo"<script type="text/javascript">
[HIGHLIGHT="JavaScript"]var minutes= $thissongsmins; //Amount of minutes settimeoutruns

I'm building a comment system modeled after Tumblr's, where each post will have it's own comments. I've modded a system from 9lessons and am having an issue implementing it for multiple instances on a page. Each post has its own ID, so I'm trying to set this up using the post's ID. It works fine for a single post, but when there's more than one on a page it doesn't work.

I want to make a script that composes an image depending on several variables. The image is composed of a base piece of clothing (e.g. t-shirt) on which an image and text can be placed. The color of the piece of clothing; the location of the image, the image itself and the text are variable. Also the font of the text can change. Is there a base script I can use? Or is there a small script that handles a piece of the desired functionality?
Probably this is a thing better done in flash. But I don't know flash and really don't want to either. Code:

I have a flash header on my website with 5 menu items (home, register, about us, etc)
myheader.swf?button=1 "Home" is focused
myheader.swf?button=2 "register" is focused
etc etc
When you click on a menu item it becomes the focused menu item (or "button") and the flash fires off a javascript event which handles the AJAX.Using the browser's back/forward buttons, the flash header's focused item does not change.
I can capture the history change, but how can I change the " .swf?button=x " using javascript.
PS: the flash header is a big file and I do not want to reload it every single time to update the var

I want to pass window size variables to javascript's window.open() function from a flash movie (actionscript) to javascript embedded in an html page. The idea is to generate a pop-up window when the user clicks a button in the flash movie. I've programmed the flash movie button like this:
on (release) {
getURL("javascript:open_win('http://www.mysite.com', winfeatures)"); }
where winfeatures is a string containing the pop-up window options, e.g. width=400,height=300,resizable=1 . I have 'traced' the string to make sure it is formed properly. These variables may change so I don't want to just insert them verbatim as the arguments. They are read from an xml file and made into a string - e.g.
(var winfeatures:String = "width="+myxml.attributes.width+",height="+myxml.attributes.height);
In the html page I have the following javascript:
<SCRIPT LANGUAGE=JavaScript>
function open_win(URLtoOpen, windowFeatures) {
newWindow=window.open(URLtoOpen, "myWin", windowFeatures);
}
</SCRIPT>
but it's not working. It seems the windowFeatures isn't being read (or read properly) and the pop-up opens with a default size.

i have this code:
var current;
startOff = $('#all').offset(),
offString = "{top :"+ startOff.top +", left :"+ startOff.left + "}";
current.css(offString);
When "offString" is alerted its fine - eg {top: 123, left: 342}BUT it doesn't seem to like it, but when the alerted output is added into current.css() inplace of offString, the element is positioned as it should be.

We are downloading a few thousand rows of data for users to choose from
and need to speed up the operation. The data is related in four levels.
The current design allows the user to select the first level from about
20 choices and then the next level's choices are retrieved from the
server. This is taking about 4 seconds. We are required to make it
faster.
We need to be able to download all the data once and save it for use
any time this particular page is visited. The app is a support app and
the page will be used throughout the day. The obvious idea is to cache
it in a Java applet but we are not allowed to use applets. The other
idea is to embed it in JavaScript arrays but we have tried this and the
performance penalty is about the same and will be incurred on other
lookups on the page becuase the page reloads for these other lookups
(we are using WebLogic netui).
What we need is a cookie that is not submitted unless the page
explicitly sends it; that is, some data needs to be downloaded once per
session and remain in the browser memory/on the disk throughout the
session. It would be nice if we could write to a temp file or access a
heap - can we? Any ideas?

I'm using ajax to get multiple vars from a database and would like to show the vars in different parts of my page but everything is shown all in the same spot with the div.
An example is I'm pulling a home number and an email from a database and want to show them in different spots.
I have it working but I have to make a seperate ajax(), url, for each var which I don't think is very efficient!
[URL] you can test the search out by typing 000-000-0000 into phone or bank into the name field and tabbing through both input fields.
