I am looking for a way to troubleshoot css rendering problems. Is there a way to find the calculated styles for any object? I would love to be able to mouse over an element and see all the styles that are causing the element to be where it is, and look the way it does. The elements must "know" this information. Cross browser would be great, but we mainly deal with intranet apps based on IE. Code:
View 1 RepliesI've got an asp page that creates fields on the page based on database information, so I don't know which fields will be there, but I do know the formula for devising the field names. I'd like to validate them using a javascript function, but I'm not sure how to access their data. So, for
example, I would like to set a variable to: "form.myfield.value", and then access the contents of that field using javascript. Can this be done, and if so, how?
I know absolutely nothing about JavaScript but I am told that JavaScrip
is needed to solve my Form problem. I’m trying to figure out how t
take 2 List fields that would have text names but would represen
numeric values and calculate them.. Code:
I have a javascript variable containing the return value from a call to showModalDialog(...)
var rval = showModalDialog(...)
I can display the contents of rval using alert or in an iframe, so I know it isn't null, but I want to save it to a mysql database using php.
I'm processing a form with numbered fields, but I don't know how many fields there are. Might be 1, might be 20. So I'm iterating through 1-20 and trying the following test:
for(i=1; i<=20; i++) {
if(typeof(eval('document.edit_orderitem_form.field_'+i+'.value')) != 'undefined') {
[doing stuff with the form field here]
}
}
The script quits on that line with "Undefined value" showing up in Safari's error console. I just can't figure out how to eval() the name of a field when it may or may not exist.
i have this select element
<select name="prods[]" multiple>
</select>
or
<input type="text" name="text[]">
now how do I access it in javascript to get the selected items and whatnot.
How can a script read a text file located on the same server as the javascript source from the script itself?

I managed to display the total but I can�t make the form to show automatically the two other values (deposit, final balance) unless I ask the user to click on buttons, which is not desirable since $ does not change automatically for deposit and final payment if user clicks on another radio button before sending the form.
2- Need to send to an e-mail the values of total, deposit and final balance, along with the choices the user made (ex: "Quad" and "Med"). I only managed to send the choices, not the totalled values.Here is the code I wrote (for demo purpose, I only put 2 choices vis-a-vis radio buttons):

I want to access the features of a plugin without actually embedding
it into a page. Is this possible? Eg
The code to embed the object into a page is:
<OBJECT classid='CLSID:7FA62735-AHC3-14d2-9F81-00114B3245C5
codebase='http://www.test.com/plug.cab#version=3,1' "id='myPlugin'
height=Ɔ' width=Ɔ'>
<EMBED type='application/x-myPlugin' name='myPlugin' hidden='true'
src='in.txt'></EMBED>
</OBJECT>
I could simply add this using document.write, but for various reasons
I dont want to do this.
I would rather do something like:
var plugin = (navigator.mimeTypes &&
navigator.mimeTypes["application/x-Web-Plugin"]) ?
navigator.mimeTypes["application/x-Web-Plugin"].enabledPlugin : 0;
myObj = new object("CLSID:7FA62735-AHC3-14d2-9F81-00114B3245C5");
myObj.pluginMethod
I am running my website using Weblogic, so the path is something like

Javascript?
For example, something like <a href='/home'>..</awill not work as
that would point to http://<myip>:<port>/home and needs to point to
http://<myip>:<port>/<servername>/home
I have a page (page 1), my page 1 has an IFRAME which loads another page (page 2).
My page 2 has a JavaScript object declared on the page: var MyObject = new Object();
I want to access this object from the parent page (page 1).
I tried:
var TempObj = document.getElementById("MyIFrame");
TempObj.document.MyObject.value = "blah blah";
But it said MyObject didn't exist.
Can someone tell me how to access it in this manner?

View 3 Replies View RelatedI've written a program which will prompt for a number of cities, Prompt for the name of the city, then prompt for the number of snowfall readings of that city, and then prompt for each of these individual snowfall readings of that city. From this, it adds up each of the individual snowfall readings of that city, and will calculate an average by dividing this figure [the total snowfall] by the total number of readings for that city. This average is used to then classify the city as "not snowy", "mild", or "blizzard". I'm happy to PM my code to anyone willing to help out, as I realise this is a complex structure to visualise perhaps, but I can't post it publicly.

I have 2 ready items. The first changes the size of the surrounding div, the second tries to find out about the size of the changed div, but only gets the old value before the first ready item started. If i place a new ready item that holds for a second (i.e. an alert box) the calculation of the first ready item is done when the last ready item starts and all works fine. Is it possible for a ready item to wait and not to start until the item before is finished?

String ans;
i want to do (multiple) file upload(s) and display a progress bar.
with firefox and safari it is no problem at all. only IE makes some
problems.
my script is based on ajax-uploader, which can be found at
www.srmiles.com/freestuff/ajax_file_uploader/ . you can do multiple
file uploads. each upload will have it's own "form"-tag, so that each
file is uploaded for its own. could be a good solution if there are
"big" uploads.
so here is what i do:
i have a html-page in which several forms with file-input fields are
generated. when i now hit the "one" submit button at the bottom of the
page a javascript function upload() starts it will iterate through all
forms (id='frmUpload_xx'), will get the filename, start a ajax request
for the progress-bar function and do a form.submit().
if the first form/file is uploaded, a settimeout('upload()', 1000); is
called and the next form will be processed. all form's have an
target="uploaddiv", where uploaddiv is a invisible iframe. so the
output of the upload script is put in this div. output should only be
a "OK" at the end. no usefull output no info no nothing.
firefox and safari are working as expected, only IE stops after the
first file is uploaded. i get an javascript error saying "zugriff
verweigert/access denied" on object line x... this is the place where
i call "form.submit()".
this is the upload-function:
function upload() {
if (uploads.length>0) {
form = document.getElementById('frmUpload_'+uploads[0]);
if (form["filename"].value == ""){
alert("Please Choose a file to upload.");
} else {
filename = form["filename"].value;
if (filename.lastIndexOf("")>0) {
filename = filename.substring(filename.lastIndexOf("")
+1,filename.length);
} else if (filename.lastIndexOf("/")>0) {
filename = filename.substring(filename.lastIndexOf("/")
+1,filename.length);
}
makeRequest("upload_progress.php?sid="+sid
+"&filename="+filename,progress);
form.submit();
}
}
}
the strange thing is, that filename is filled correct, that means the
object "form" is found and exisits. the first iteration is working,
only the second ends with an error.
think it have something to do with redirecting the output of the
upload-script in an iframe. after that IE can't access form - at least
IE is not allowed to submit the form as i can access a form field
(filename).
i worked on that the last two days and haven't found a solution...
The following javascript code generates an "Access denied" error at the indicated line.
This sample should allow the user to click "Browse" and choose a file. Once
the user has selected a file the form is automatically submitted. I'm trying
to avoid having seperate browse and submit actions.
Can someone explain why I'm getting the error and how I can accomplish this
task? Code:
just came across this in a book for browser javascript on/off detection:
Code:
<noscript>
<img src="monitor.php?scriptoff=true" />
</noscript>
just wondering if browsers when js is off will ever access any
<script type="text/javascript" src="file.js"></script>
files? i mean wouldn't it be better not to bother with the noscript thing and just be aware of if file.js is accessed? or do some browsers access the file.js even when js is off?
I've got a page that creates a new div and assigns it a new div id (via a counter) and adds it to the page via the DOM.
I'm trying to duplicate a particular div based on user selection and need to pass it's div id to the duplicate function.
I can't figure out how to either print the div id to screen or enable it to be passed back to the function.
Manually its fine : onClick="dupDivCont('stuff3')" and it just duplicates the div with that id.
Is there any way to get the div id into that onclick function to replace 'stuff3'?

The browser shows the alert but causes an error "access denied" and
fails to set the upload.value to null.
for(var i=0; i < fileName.length;i++) {
if (fileName.charAt( i) ==' ' || fileName.charAt(i) == '*') {
document.forms[0].upload.value=''
alert("No spaces/wildcards allowed in file names"
+ f.upload.value);
return;
}}
