I have no idea why id is undefined in the arrow below:
<html>
<head>
<script type="text/javascript">
var id;
function window_onload()
{
id = "8888";
alert("ID = " + id);
}
</script>
</head>
<H2>Page 2</H2>
<body onload="window_onload()">
<P>id = <script type="text/javascript">document.write(id);</script> //<****
</body>
</html>
I am trying to make a function that will return part of some xml data, but It keeps returning "Undefined" here is the function, with the call:

I'm displaying a loggin page.
If the user entered an invalid UserName/Password I display the page again.
When this happens I want to give the user a different message then the one displayed when the page was initially displayed.
I use the Response.Redirect method from the page checking the submition.
When I do that I call the page with a parameter like this Response.Redirect("Page.asp?FROM=1").
When I get the parameter in the page I know I need to show a different message.
The problem is that if the page is called without the parameter, I
cannot determine that the parameter is missing.
The codse is very simple:
from_flag = Request.QueryString("FROM")
Now is the problem -
if I use if(from_flag == 'undefined') - this condition return
false.
but if I display from_flag using Response.Write(from_flag) I get "undefined"
if I use if(typeof from_flag == "undefined") - this does not work since the typeof return "object" in both cases when I call the page with the parameter or without the parameter.
also I tried to comnpare with null does not work.
By the way if I use VBScript as the script lang - it works fine I just need to compare the from_flag with vbNullString and all is well....
I have a really simple scenario which got broken after upgrading to 1.5.the defined handler for the success callback in $.ajax doen't set the data parameter - it's always undefined. This works fine in 1.4.4.
View 3 Replies View Relatedhave the following code that I thought I could retrieve json_encoded data but I'm just getting "undefined".The json_encoded string from the php array:{"table":null,"id":"2","itemCode":"1003","itemDesc":"Item infor for1003","itemWholesale":"1.99"}]I thought I could "grab" the name of each in the array and output the dataaccordingly. So on success of the ajax post (which does return data) I triedalert(itemData.itemCode); This is on line 10 in the below code snippet. Using this method returns "undefined" and NOT the data 1003 as I would expect.

I am working on Pinax (Django) and jQueryMobile, and I got this error:
Also, there is a javascript error: l.data("page") is undefined
I used the code provided in Modern Web Design using JavaScript and DOM by Stuart Langridge to build a JavaScript sliding menu for navigation. I copied and pasted all the code, but I get the error message "EventCache is undefined" on my page. Can anyone explain why this is happening. I am a novice with JavaScript and was using this to learn.
The code in particular is as follows:
addEvent: function(elm, evType, fn, useCapture) {
// cross-browser event handling for IE5+, NS6 and Mozilla
// By Scott Andrew
if (elm.addEventListener) {
elm.addEventListener(evType, fn, useCapture);
return true;
} else if (elm.attachEvent) {
var r = elm.attachEvent('on' + evType, fn);
EventCache.add(elm, evType, fn);
return r;
} else {
elm['on' + evType] = fn;
}}
};
I am working on an application in which monthly calendars of events are to be generated. When the page is initially loaded, the current month's calendar is generated using Javascript; the user can also move forward to the next month or backward. For each month, I need to be able to retrieve server-side data (using PHP/MySQL) to fill each day-cell ("td"+i, below) of the calendar with events for that day which reside in the server-side database, keyed by date. Here is a snippet of the code that generates the days of a given month:
var d = 1;
for (i = 0; i < 42; i++) {
var elem;
var elem = eval(document.getElementById("td"+i)); //the day cell
elem.innerHTML = "";
if (i >= startingPos && i < lastpos){
elem.innerHTML = d
d += 1;
.
.
return;
In short, I need to get data from the database as the days are created (elem.innerHTML = d, above) or get all the data for the chosen month (probably more efficient), and send it back to the Javascript where it can be parsed and loaded to the appropriate cell(s) in the calendar.
I am trying to develop a function where the user rolls over the days ( all inside their own <td> ) inside a table of a single month calendar. And when he clicks on a day, it get its color permanently changed until he choses another day for focus. I tried onMouseOver, onClick and onMouseOut, but I just cannot find a way for it to lose focus on the day last clicked when I click anew.
View 3 Replies View RelatedIs there a way to retrieve POST data submitted from a form using Javascript?
I know I can use PHP, but for lengthy reasons I cannot so I only have JS to work with.
I've been using some code to verify form data quite happily, but i've
recently changed the way my form is structured, and I can't get it to work
now.
Originally :
The form is called "form1", and I have selects called "PORTA", "PORTB" ...
etc...
I then had javascript that accessed these selects as below, and it worked
fine.
ind = document.form1.PORTD.selectedIndex;
val = document.form1.PORTD.options[ind].value;
dev = document.form1.PORTD.options[ind].text;
My form is now autogenerated, and form data is stored to file, so I now use
an associative array for thte form elements (so that I can loop through them
easily), The form elements names are now :
McuCfg[PORTA], McuCfg{PORTB} and so on
Now, I modified the javascript so that it now uses the McuCfg[] associative
array :
ind = document.form1.McuCfg[PORTD].selectedIndex;
val = document.form1.McuCfg[PORTD].options[ind].value;
dev = document.form1.McuCfg[PORTD].options[ind].text;
When the script runs, I get the error
"document.form1.McuCfg.PORTD is null or not an object"
I have used the same notation that i know works for the "options" array
although that's not an associative array.
I am trying to use javascript just to make a gui for a program written in C++. I am having trouble finding any information on how to input data obtained from a user in the javascript application into the C++ program if it is even possible.
View 5 Replies View Relatedcan anybody help me in writing a javascript function which opens a
popup window with the target URL when the link "POST Request" is
clicked..
Points to note:
The HTML DOESNT and SHOULDNT HAVE A FORM TAG.
The URL data should be sent as POST and not GET..i.e the search
parameters should not be showin in the address bar when the page is
opened.

im trying to get values from a database and assign them to icons which display on my page. The icons that are generated on the page are generated in javascript- and they do work. Howver i want icons to hold the names that are in the database/table.
how would i do this? would this be using a query result in asp to get the values from the database?? how would i do this? please provide code or guide.
then, how would i assign the database value with the icons???? ive heard javascript arrays??? how would i assign the values??
If the XML contain over hundreds+ nodes and text, is it even remotely possibleable to do the code?

I wonder, what is the simpliest way to send data to PHP script from Javascript? For example, user clicks some image and JS runs some PHP script in background (so browser keeps loaded page) which makes few MySQL queries etc.

I need to grab the last 5 rows from my database (2 fields per row) and list all 5 in a table but from within a .js file that I can externally link to.
I can manage the php / mysql and the output to a .php page but how can this be contained within a .js file?
I believe it is possible but after 2 days of searching on google I'm appealing for assistance.
I realise this could be done with a php include or iframe but that isn't an option and the only way available to import this data is via an external javascript script.

I am working on a PHP-script and need javascript to set the value of a
hidden field in a form. This field happens to be an entry in an array

another that does work, but do not use an array entry in the hidden field. Code:
I am using .ajax() to access cross-domain data using JSONP. Because I need to be able to cache the data I want to use a static name for thejsonpCallback function, so I have set the jsonpCallback option in the .ajax() request. However that appears to requires a global function whereas the auto generated function didn't (well maybe it did but that was all hidden from me).
I definitely need to be able to cache the results. Ideally I wouldn't have a global function handling the data. Is there another way to do this? If not what is the best practice way to go about using a global function these days and how do I provide it with the context of the object/module it was called from - which is where the data is needed?
