JavaScript - Access Javascript Variables From Another Javascript File
Hi,
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?. Similar TutorialsAll -- I have a JavaScript config file called gameSetting.js which contains a bunch of variables which configures a particular game. I also have a shared JavaScript library which uses the variables in gameSetting.js, which I include like so: <script type="text/javascript" src="gameSetting.js" ></script> <script type="text/javascript" src="gameLibrary.js" ></script> In gameSetting.js I have: $(document).ready(function() { // call some functions / classes in gameLibrary.js } in Firefox, Safari, and Chrome, this works fine. However, in IE, when it's parsing gameSetting.js, it complains that the functions that live in gameLibrary.js aren't defined. When it gets to parsing gameLibrary.js, the variables in gameSetting.js are reported as not being defined. I've tried dynamically bootstrapping the gameLibrary file using this function in document.ready for dynamic load... $.getScript("gameLibrary.js"); However, the same problem still happens in IE, where when it parses the files individually it's not taking into context the file/variables that came before, so it's not an out of load order problem. My options a 1) collapsing all the functions in gameLibrary.js and variables in gameSetting.js into one file. However, this is not practical because this is dealing with literally hundreds of games, and having a gameLibrary.js in ONE location for ONE update is what makes most logical sense. 2) figure out a way to get this to work where variables in file1 are accessible to file2 in IE (as it seems they are in other browsers). jQuery seems to be able to have multiple plugins that all refer to the based jQuery-1.3.2.js, so I know there is a way to get this to work. Help appreciated. Nero Hi, I'm very new to javascript and I need your help.

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.

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 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 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 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'm looking to use the document function in javascript to change the TYPE of an INPUT. However I want to change the TYPE of the INPUT according to a variable passed to the javascript button, so i use: document.formname.inputname.value="newvalue"; I want to be able to change what inputname is depending on what is passed to the function, but right now firefox is telling me that it's undefined. Is there any way I can do this? Thanks in advance, Daniel Hi, Ive got a iphone based website im writing in html/javascript, it all works perfectly well apart from an issue with a javascript variable and i cant figure out what im doing wrong At the start of the code i declare a variable var jpgname='blank'; - its blank for testing I then have a href which attempts to change this variables value when clicked <li class="flip"><a onClick="jpgname='test'" href="#page">Cars</a></li> If i replace the jpgname='test' with confirm('test) i get a popupbox so i know its running this code under my #page section (just a div named section) i have [<h1><script>document.write(jpgname);</script></h1> however this always has the value 'blank' Im sure im doing something stupid but im not sure what Any help gratefully recieved thanks Mike I am perplexed about this one. Not sure if php is the best solution or maybe javascript. ( or both.) I am writing a litle script that will go to my mysql table and take out 20 rows ( from about 10,000 rows ) based on the WHERE statement. Then I want to step through these 20 rows displaying just two filds in this fashion: First, I want to display one field in a "box" ( using divs and css ) then wait for a form input. Then while keeping the first displayed box and field display the second field in a similar box a fee lines below. Wait for a form input update some data. Then onto the next row. If I use javascript then I could keep all the processing on one page and not have to have server refreshes. But how do I get these those array elements from $row['field1'] and $row['field2'] into javascript vars ? Is this the best way to do this ? Or would php and having a couple of extra trips to the server for form processing be better ? Thanks for any input. . I have jQuery like: jQuery(".forms_1_1").validate({ rules: { inputname1: { required: true, }, or inputname1: { required: "Requested field!.", }, Is it technically possible to add 1. PHP variable like $_SESSION and 2. Smarty variable into Javascript like {$global.variable1} inputname1 is value for each variable (PHP, Smarty). Need help how to include variable values into Javascript code. I am about to translate some C++ code to JavaScript. In C++, it is straightforward to declare and use a Boolean variable; all I do is swap it between true and false and back again as needed. For example, Code: // C++ Code . . . bool na = 1; . . . na = !na; . . . I am wondering if JavaScript offers boolean variables. As far as I know, it does not, but I thought I would confirm by asking around. At the moment, I am planning to code the comparable block in Javascript using an "if" statement or a ternary operation. For example, Code: JavaScript Code . . . var na = 1; // Option 1 if (na) na = 0; else na = 1; // Option 2 na = ((na) ? 0 : 1); . . . Is one of these options recommended as the best way to simulate a boolean variable and operation? (I would like the fastest-executing code possible.) Or is there another--better--way to do it? All advice and recommendations appreciated. Thank-you in advance.
