JavaScript - How To Server-side Process Form And Output To Same Page?
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. The code is this: Code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">

Right down the bottom, under the word 'Quote is where the output should go. Any suggestions on how to do this? Regards Jenny 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 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, 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/ 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 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. 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.
Hi all, I would like to have an HTML button which, when clicked by the user, contacts the server and runs a Python script on the server. When the Python script finishes running, the current HTML page automatically reloads a file from the server. Is that possible? YJ 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 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 I need for the form to do the following: when age is greater than or equal to 65 enter "yes" in the hidden field when age is less than 65 enter "no" in the hidden filed return true Create a page processAge.htm that Writes the message on the page Hi name. At age # you may retire. or Hi name. At age # you are not ready to retire. Get to work. name is the name entered on the form. # is the age entered on the form.

Thanks for any help! I've literally tried everything. Read 26 tutorials, interchanged code, etc. My validation functions all work. My AJAX functions work (tested manually using servlet URL's). The second servlet validates the reCaptcha form that's generated on my webpage. After the form is validated, even if everything's correct, nothing happens upon clicking submit. I even have an alert pop up if with the captcha result, just for middle-layer debugging purposes. I want to do all of my validation clientside; none serverside. However, going to be tough if I can't get my god damn form to submit. I've been puzzled by this for close to 36 hours straight. I can't see, and I'm going to get some rest and hope that there is some useful insight on my problem when I return. html form: Code: <form id="f1" name="form1" onsubmit="validate_form(this); return false;" action="register" method="post">

Hi, I am creating a HTML page and mailing it to the user(client side). This html page contains a Table and a button. On button click, I would like to create another HTML page based on the detail in the table,dynamically on run time and Open the newly created HTML. I need to use javascript to achieve this functionality. I have no Server-Client Configuration. And I need to run the Javscript only on client side to process the First HTML's table data and Create a new HTML page. The output of the javascript should also be put in a table format in the newly created HTML page. Here is some background information: The details from one server would be put into this first HTML along with a button. This HTML page is then mailed to Client side. The javascript in the HTML page then processes the Table data of first HTML. This can only be run at Client Side,once the user clicks the button and moreover I dont have Server-Client Configuration. I am creating a report and mailing it, For formatting purposes and for creating hyperlink to mailid's I chose HTML, Now I am struck here. Could some one please help me out with this.

http://www.codingforums.com/showthread.php?t=87742 I've been using the advice and code here to start incorporating expanding/collapsing tables into my work, but I'm hitting a little problem. I want to have multiple such tables side-by-side (each headed by a picture and populated by a lightbox, which isn't the issue), but Dreamweaver wants nothing to do with the idea. I don't really even know if it's possible, but if it is I'd like to know what sort of changes I might need to make to achieve it.
Hello, I have a 2 level combo box that are dependent on each other and what I want to happen when the "submit" button is selected is for an html text answer to be displayed on the same page below the combo boxes based off of what was selected in the second combo box. I've tried using hide/show functions with JavaScript but couldn't figure out how to link the 2 scripts together. What I have is as follows: Code: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/1999/REC-html401-19991224/loose.dtd">

Thanks guys. Hey guys, I am pretty new at javascript but am trying to learn. Here is a problem I have encountered. I have made a form with various input fields and a set of radio buttons which change the parameters of the form. One of the radio button sets is "Search by X" and "Search by Y" I want the action parameter for the form to change depending on whethere X or Y is selected Code: <FORM name=ENTRY_FORM onSubmit="return Check();" action="pointMeTo()" method="get"> If X is selected then action="http://site.com//doSomething.action" if Y is selected then action="http://site.com//doSomethingElse.action" The way I attempted to do the above(and I am not claiming this to be most efficient, just what comes to mind at the moment) is to create three functions and two global variables. Code: var xyToggler = false;
var out = "";
function toggleX(){
xyToggler = false;
}
function toggleY(){
xyToggler = true;
}
function pointMeTo(){
if(xyToggler){
out="http://site.com//doSomething.action"
}
else
out="http://site.com//doSomethingElse.action"
}
Thats the javascript part, now on the html form part: Code: <FORM name=ENTRY_FORM onSubmit="return Check();" action="pointMeTo()" method="get"> <!-- Stuff --> <input type="radio" name="choose" id="X" NAME="rbXY" value="X" onClick="toggleX()" checked/><label for="X">X</label> <input type="radio" name="choose" id="Y" NAME="rbXY" value="Y" onClick="toggleY()" /><label for="Y">Y</label> The logic seems like it would work to me, but when I try it out the results that are expected to come depending on the parameters X or Y are not displayed, in fact nothing is displayed but a msg saying that there is no such link. So I am assuming that means that the function is not properly assigning the corresponding links to the action= field in the form. Many thanks to whoever can spot my error or give me some advise! All the best. |
