JavaScript - Upload File Server-side Javascript
I'm attempting to pull the hidden iframe file upload trick using javascript. I've go my form file upload and iframe fine, but I can't figure out what to do when it gets server side. There seems to be relatively no documentation on how to handle uploaded files in server-side javascript. Ideas? I'm at a loss.
Similar TutorialsHi people, I need help as follows: On the server side I have a php generated session parameter. I need to pass it to javascript on the client side page. I saw on the web the following solution: <script language="JavaScript"> var mySessionVar="<%= Session["MySessionVar"] %>"; </script> I tried it but it did not work. I could not find any explanation of this syntax - will appreciate one. Any suggestions, maybe in another way? Thanks I would like to use functionality similar to DirectoryInfo and FileInfo using server-side javascript in ASP.NET, but neither are recognized. What are the equivalents, if they exist, in javascript?
Hi, I have a script that writes to an IFRAME, it writes dynamically and then needs to reload it server side. Anybody knows how to do it? I'm joining the code of my attempt but it appears to be reloading the IFRAME on the client side therefore causing an activeX error since I am running this in FireFox: PHP Code: var frTraductionID = document.getElementById("frTraduction"); frTraductionID = (frTraductionID.contentWindow) ? frTraductionID.contentWindow : (frTraductionID.contentDocument.document) ? frTraductionID.contentDocument.document : frTraductionID.contentDocument; var x=frTraductionID.document.getElementById("hCount").value; var ifrm = document.getElementById("ifUPDATE"); ifrm = (ifrm.contentWindow) ? ifrm.contentWindow : (ifrm.contentDocument.document) ? ifrm.contentDocument.document : ifrm.contentDocument; ifrm.document.open(); ifrm.document.write('<scr' + 'ipt language=javascript type="text/javascript" runat=server>'); ifrm.document.write('var fso = new Active' + 'XObject("Scripting.FileSystemObject"); '); ifrm.document.write('var f = fso.OpenTextFile("' + sFileName + '", 2, true); '); for (var i=0;i<x;i+=1) { var sString=""; sString +="f.WriteLine('"; sString +=frTraductionID.document.getElementById("h"+i).value; sString +='="'; sDetail=frTraductionID.document.getElementById("d"+i).value.replace('"', ' '); sDetail=sDetail.replace("'", "`"); sString +=sDetail; sString +='"'; sString +="')"; sString +="; "; alert("i = " + i + " str = " + sString); ifrm.document.write(sString); } ifrm.document.write("f.Close();"); ifrm.document.write("</Scr" + "ipt>"); ifrm.document.close(); document.getElementById('ifUPDATE').contentWindow.location.reload(true); any help would be appreciated. Hi, I have created a global navigation includes document. Unfortunately the drop down menus that are part of the navigation aren't working. They worked fine when they were part of the page, but now that they are separated from the page as includes the drop down menus don't appear in my test site (posted to a web server). All other content in the includes file appears and works. Any ideas? Thanks for your help. I am developing a mobile app. I have a script that will read the contents of a csv into an array. It works great, however I am not sure how to take that array and insert it into a db. The following is the script that reads the csv -- function IO(U, V) { var X = !window.XMLHttpRequest ? new ActiveXObject("Microsoft.XMLHTTP") : new XMLHttpRequest; X.open(V ? "PUT" : "GET", U, false); X.setRequestHeader("Content-Type", "text/html"); X.send(V ? V : ""); return X.responseText; } var mycells = IO('data.csv').split(/\n/g).map(function(a){return a.split(/\t/g)} ) I want to insert the array 'mycells' into the db but do not know what the correct syntax would be. t.executeSql('INSERT INTO mytable (name, phone, street, city, state) VALUES (????????????... Thanks for any helps that is sent my way! So, this is my last problem. If I can nail this, then the website will be completely AJAX driven, and will be spectacular. It took me a while to figure out just how to ask the question. lol Now it is really simple. 1) When I hit the button, in the simplified example below, the website sends a code to the server. 2) The server then re-writes the "xyz.js" JavaScript file with a new array of values. Is there any way to re-retrieve that JavaScript file, from the server to make it the current "xyz.js" rather than the old one that loaded on the client originally. I can get a new XML data file and re-submit that to the website, but how do I re-retrieve the new JavaScript code? Code: <html> <head> <script src="xyz.js" type="text/javascript"></script> </head> <body> <button onclick="onload();">Change</button> </body> </html> Hi there, I have a File Upload tool and would like to prevent the users from clicking on the textbox to upload files.

Hi everybody, I have this File Upload control, whereby the user is granted a limit of 5 uploads. And so, the user clicks on "Attach Another File", and decides to attach a file ONLY in the first File Upload control. My problem is, I want the user to be able to click on an "X" beside every File Upload control, so that it will close those unnecessary (or unused) FIle Upload controls.

I am trying for a javascript code that would ask for the excel file location when run, fetch data from two columns till eof in an excel file (MS Excel 2010), append it to an existing text file and upload the plain text file to an ftp location. The ftp username, password and location needs to be hard coded in the script. Is this possible? I have a form field that needs to be validated in a hidden Iframe which is driven by Coldfusion. Which is working fine. But the same form field also need do some client side validation as well if Server side (iframe) validation passes. I thought I could create a javascript function, in it call a server side validate and then client side, but without any success. It does not process in the order as expected. Javascript always go first, then the server side validation. I tried to delay the client side with time delay, then server side did process first, but client function could not recognize the parameter passed. here is the function: Function doValidation(param1,param2,param3,param4) { .... document.iframName.src='serverValidate.cfm?m1=param1&p2=param2'; .... clientValidate(param3,param4); } If only I could have serverside validation return a value the function, then I could defined that value then the the clientValidate(param3,param5) to start other wise warn with a message. Both validation does work seperately. The issue is it triggered by one onChange event I have to put them in one function. Maybe I am on a wrong track. Please advise if anyone could have better solution. Thanks in advance. JT Hi guys, I need your expertise regarding my dilema. I was able to create a simple google map html page at our web server, this web server has access to the internet. the problem is, when this page is accessed from a different PC that has no internet access, the google map won't work. I know that javascripts are run at the client side, so i'm asking is it possible to run everything at the server, including the javascripts and still output the google map? i used this tutorial to make my google map page : http://googlemaps.mayzes.org/ Hello again... I have written a custom slideshow script which gets the images from an array... The script will change the src of a img, which is a fullscreen background. Now here's the problem, I've been trying to write a function where can define a folder "gallery\test\", and then get all image files in that folder and repopulate the slideshow array. So, is there a way to scan folders? I've searched around and found some solutions where PHP is used, but i really want to keep this pure js, if possible (?) Thanks, I have the following JavaScript (see below). The script requests an XML file from the server and displays it on the page. The script works fine when the requested XML file is stored on the same server as the script. The problem is when I try requesting an XML file from an external server such as the National Weather Service. I get an error. If I take the XML file from the National Weather Service and save it to my server it works. Why can't I use my script to request XML files stored on external servers? Thanks in advance for any help.

var xhr = false;

makeRequest(this.href);

When the Python script finishes running, the current HTML page automatically reloads a file from the server. Is that possible? YJ I have a form that I've made in the XHTML comprised of text boxes and radio buttons. I want to put a button on the page that when clicked, takes the values in the data, processes it client-side and then outputs it to the same page that it took the data from. I'm having difficulty know exactly how to reference the data in each form element. So far, it seems like I can use getElementById, but my efforts so far have stymied me.

Right down the bottom, under the word 'Quote is where the output should go. Any suggestions on how to do this? Regards Jenny I know that Javascript is client side, but I'd like to know the best way to populate HTML drop downs in real time based on information typed in the other HTML form fields with information found on the server as opposed to the client. For instance if a user wants to select certain files located in a directory on the server, as they type in the pathname supposedly containing the files the drop downs continually refresh themselves with the server files listed in that directory (if it exists, and apache has permissions to see what's inside) as if it was showing client files instead. What would be nice is if my browser could continually query the server for some of its private information and not have to refresh itself to obtain it, whether that means the server-side would have to continually refresh itself makes no difference to me as long as the client-side doesn't have to. But I guess this is not possible because no matter what you would have to at least refresh the client-side page once? Submitting the form to a CGI or PHP script would not work because I need this functionality to help populate the form BEFORE I send it. I would like to not have to press a button to update the form every time I change the pathname and need to update the drop downs since this would be annoying. I'm open to anything that could do this or something similar not just Javascript. I'm not sure if you could accomplish this by converting the HTML page to CGI/PHP and having it continually reload itself without refreshing the page? I'm not worried about any security risks this may pose because: 1) The server is located on company intranet which is firewalled 2) I could always password protect and encrypt all transmissions, making sure only authorized users use the app Hi, I am trying to write a small web app that is used to do some plots for over-the-time-collected data (children's growth measurements). The current objective is to re-use entered data. As I do not want to store anything on the server (which would lead to all the annoying username-password-stuff), nor in cookies, I would like put measurements into a local file and reload them into the HTML entering form. I know and fully appreciate that javascript is not able to read or write files; it is on the other hand obvious that this can be bypassed if I upload the respective file to the server which returns it in an ajax fashion. My main question is now: Is it possible to do some kind of internal upload, that ends up in a read of a local file? Something like a <form method="post" action="localscriptname" ...> with an <input type="file"...> field? Another (off-topic) question: My plots are in PDF format. I accidentally appended some data to the PDF file which did not cause any problems for the pdf readers. Can I rely on the fact that any pdf reader will ignore data after the %%EOF mark, but will keep it if a file is downloaded, directly opened by acroread or whatever, and later saved from the reader program? This would allow it to keep the plot and the raw data in one file and might be helpful for the not-so-computer-affine target audience of my program. Greetings! All -- 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 |
