JavaScript - Javascript Parental Access... How To?
Hello everybody, I am new in this forum (and I'm also new in web coding, but not in programming)...
This is the first problem I met: I can't understand how to acccess a property in this snippet: Code: function FGGE()
{
this.totalExternals = 0;
this.loadedExternals = 0;
this.loadImage = function(image)
{
image.onload = function()
{
alert("Loaded 1: "+this.loadedExternals+"/"+this.totalExternals);
};
alert("Loaded 2: "+this.loadedExternals+"/"+this.totalExternals);
};
}
Output is this: Loaded 1: NaN/undefined Loaded 2: 0/0 Could someone help me fixing "Loaded 1"? Thanks a lot Similar TutorialsHi, I have the following code snippet: test.html ====== <script language="javascript" type="text/javascript"> var testVariable = "test"; </script> <script language="javascript" type="text/javascript" src="test.js"> </script> test.js ===== var testVariable = window.top.testVariable; In firefox, I'm able to access testvariable defined within test.html in test.js. But in chrome, test.js couldnot get the window.top.testVariable field defined in test.html. Can any one please let me know how i can make it work in chrome?. Am i missing something here?. hi, i want to make an ftp access page using javascript i know it's possible using "ftp://" , but when i use this, the browser loads a window with the ftp folder i want a javascript to get ftp access and to give the commands itself any1 who knows how to get ftp access and ability to give file send/receive/... commands with javascript? Hi all, Have problem from getting data of JavaScript Object ie. Associative Array. Code: var a, table1
a = new ActiveXObject("MyProgID"); a.GetDataFromExcel("C:\\Users\\myFolder\\Desktop\\test.xls","Sheet1")
a.Generate()
table1 = a.writeInTable();
Here writeInTable function returns a 2D Object array from DLL written in VB.Net. So I got the Object to table1. But from table1, I can't access the values but its there. table1 shows values as in this image(Image Attached.) Actually, I tried many ways like tab(0)(0) tab[0][0] tab["0"] tab.(0).(0) tab.[0].[0] Also with toArray(), (new VBArray(tab)).toArray().... I don't know what I am wrong..Can anyone help me on this? Thanks... Shanmugavel.C Hi, I want to access SQL database using javascript. I am passing 1 value to the java script but I want to pass that value further to the SQL query as an where clause parameter to retrieve data. If the value retrieves multiple or single data then how do i handle it. Is it possible to use dataset in javascript? Regards, Anthony. Hi someone please let me know the way to access a smarty value with javascript? my smarty value is = {$value.url} i want to access it like Code: <script type="text/javascript">
function load()
{
document.location = '{$value.url}';
}
</script>
i tried with wrapping code with {literal} {/literal} but it isnt working. can some one correct this please sorry for bad english Thanks I have two servers jboss and ejabbered and i have deployed two html files, one on each as follows: testdirver.html deployed on ejabbered <html><head> <script> function viewmembers() {var w=window.open("http://192.168.56.134:8080/nkms1/kms/test.html");} </script> </head> <body><form name="sub" > <input type="text" id="to" name="to"> <button onClick= "viewmembers();"> </form></body></html> test.html on jboss <html> <script> function abc() {alert(window.opener.document.forms[0].to);} </script> <body onload=abc();></body></html> Problem: window.opener.document gives the js error "Access is Denied" which i am not able to understand. Exchanging the two files on the servers(i.e. testdriver.html on jboss and test.html on ejabbered works fine and i get the output [object]). So i am guessing there is something that has to do with the ejabbered server Here is the scenario friends, I have an html page which I load it on a server. I give the URL of this page to my clients. My clients have their digital certificate in their web browsers. There is some data on the html page which is filled by the clients. When the client hits the submit button, a java script should run from behind which should be able to pick up the digital certificate of the client which is laoded on their web browser. This information must be sent along with the data to the server. Is it possible to do this using Java script? Can we access Certificates on a system via Java script? Are there any API calls which can be used in Java script for this purpose? Any help will be appreciated. Thank you for your time. Regards, Rocky I am a relative javascript newbie. I wish to detect when a user is leaving a page, and want to know what s/he is doing to leave that page (browser BACK vs. clicked URL), and would like to be able to get this information from the ... document? Where is it held? How can I know this from within my script? Thanks Eric Hi, I'm very new to javascript and I need your help. What I'm trying to do is: I have a html file with javascipt embeded in, in this file I want to use a table object in another javascript file. How do I access this object? Your help is very much appreciated. Regards, lep2 I am starting a new project soon. Now, the project is still in the stage of planning. But I am quite confuse now which programming language to implement. I am going to design a system where the normal users will update the data with the system while the data required changes will need system administrator to apporve it. I will need a database to keep those records (the data required update) so that the system admin can refer to the database and make changes. Do I have another choice instead of using Microsoft Access 2007 macros or VBA ? I prefer a web-based programming. Any suggestion, please ? Hi All, I have html pages with code like <div> <script type="text/javascript" src="http://myserver2/mysite/addhtm.js"></script> </div> the script adds some html code and random images selected from second server inside an iframe tag in the div tag. I need to examine this added html and image properties in my page using javascript. A search on internet did not help, it says elements inside iframe coming from different domain can not be accessed. Is there any workaround or hack available to access iframe contents from page javascript? Thanks This is a question more about an ASP.NET web application, but javascript is involved, so I'm hoping some javascript gurus can assist me. I'm working with a web application that needs to get access to an ASP.NET web control (a button) in javascript. The problen is that since the control is run on the server, javascript can't access it in the standard way (i.e. document.getElementById(controlId); ). I've actually solved this problem before in a different application, but my solution there doesn't seem to work here for some reason. I have this in an aspx file: Code: <script...>
...
function myfun()
{
var b = document.getElementById("<%=SaveButton.ClientID%>");
alert(b);
}
</script>
...
<asp:Button ID="SaveButton" Text="save" OnClientClick="myfun()" ClientIDMode="Static" runat="server" UseSubmitBehavior="False" />
I have a designer class in which the button is declared (and therefore exists in the server-side codebehind): Code: protected global::System.Web.UI.WebControls.Button SaveButton; But when I click on my button, the alert box says "null". Why am I not able to get my button in the javascript function? Some things to note: *The button exists within a content tag: Code: <asp:Content ID="Content1" ContentPlaceHolderID="ContentPlaceHolder1" runat="server"> *I'm working within Visual Studios 2008. Hi, Is is possible to access a global variable for use inside a function? Thanks for help in advance Mike Hi I have developed an internet mapping site which uses an html viewer with various frames to pull in a mapping window, a legend / key and a frame of tools amongst other things. It works absolutely fine in Internet Explorer version 6, but whilst testing it in Internet Explorer 7, my mapping window is not loading up the image. It might seem strange me posting this in a javascript forum but as the error is javascript related I thought I would give it a shot! The error message I am receiving is "Access is denied". After looking online, it appears as though this error could be linked to the use of frames; and those frames trying to access other windows with different document domains?? Does anyone know if new security measures have been implemented in IE7 which restricts the use of frames? My code is below; does anyone notice anything that might give this kind of javascript error? Any help will be greatly appreciated as I do not tend to dable too much in javascript! Code: <META HTTP-EQUIV="Pragma" CONTENT="no-cache">

it is said that the 'form' node can be accessed by document.forms.certainName but it fails on my browser(IE8) however for images, it works, that is, document.images.certainName returns a Node. is there bugs only on 'form' tag? btw, document.forms[0] works ... quite quirky... Sup gents. Excuse my tenaciously novice questions, but dont disparage just yet, im beginning to grasp how the mechanism behind the code words, in due part to your helpful suggestions Im in the last stages of the code. In this section i have added three methods, whose function is to direct access control over the ciphers i will be adding shortly. I firstly need for the methods to be working. What they do is, categorize the set of values inside the first array and give a set of names privileges. The three methods that deal with the access control are link(), secondgroup() and third group. Ive assigned that the first three names( link() ) can access all the ciphers, ie administrators, the next three names ( secondgroup() ) can only access the shift, permutation and vigenere ciphers and the rest ( thirdgroup() ) can access the other remaining ciphers. But ive added so much code at once that i overwhelmed myself and i now i cant figure out where ive gone wrong, be it in the syntax or the logic Code: <html>

i noticed today that if i type in my js file name in the url i get a download box, i have an htaccess on my site so this should not be happening, thats another issue.. my question is, is there a trick to creating a js file that cant be accessed in this manner, i was thinking about adding a php define statement as it comes from one source only, but i wanted to ask first to see if there was something on the js side i could do or is that strictly a htaccess or server side issue.. Hi this is what I want to do. I have an online store and a need get fixed the machines from where my clients use my web site. what I'm doing right now is using an activeX to retrieve theirs OS code, HD serial number and other stuff and is working fine but since I'm using an ActiveX they are forced to use Internet Explorer and that's the big problem. my clients agree for me doing this check on their computers, actually they allow the activex to run, but they are requesting the posibility of using for example mozilla. thanks in advance and sorry about my english I'm just learning How would you access information about various attributes of an element with javascript?
I'm trying to write a little Greasemonkey script (in Firefox) to manipulate the top bar Google Translate produces when translating a site. For example: http://translate.google.com/translat.../www.google.de. Google has employed traditional HTML frames. According to many websites, I can use something like window.frames[0].contentDocument to access the first frame. However, this is refusing to work! I have been debugging this for hours. I have verified that I am indeed running the script from the top-level window (window.parent === window.top), and I am able to manipulate the frames themselves without a problem. When I try something like window.frames[0].contentDocument.URL, it returns as about:blank (I also get this with the other frame, i.e., frames[1]). I have tried several different methods of getting at that frame, including getElementsByTagName("frame")[0] (which works for manipulating the frame itself, but not for editing the frame's content through contentDocument). Here's my little script so far. I've included the first part so you can see for yourself that I'm definitely in the top-level window and using the right @include because it works. In this example, the URL returned is "about:blank" (again, I'm in Firefox). Code: // ==UserScript==
// @name GTranslate
// @include /^https?://translate\.google\.com/translate\?.*/
// ==/UserScript==
// change how the frame is displayed
var bar = document.getElementsByTagName("frame")[0];
bar.removeAttribute("noresize");
// manipulate the content inside the frame
var gt = bar.contentDocument;
alert(bar.URL);
