JavaScript - Not Sure Why I Don't Get A Response After Hitting Submit In This Code
I have the following files in the same directory. I can get index.php displayed but when I enter anything and hit submit I cannot get the or die message to display. I have the files in the c:\xampp\htdocs\ folder and am using http://localhost/index.php from a browser.

$username = $POST['username']; // setting php var '$username' to equal 'username' from the index.php page (POST method)
$password = $POST['password'];
if ($username&&$password) //are true
{
$connect = mysql_connect("localhost", "root", "") //creates connection to database, we're creating a var called
or die ("Couldn't connect"); //'$connect' and now we have 3 var's. 'localhost' is the host. 'root' is the
//username.
mysql_select_db("phplogin") or die("Couldn't find db");
}
else die("Please enter a username and a password!");

Thanks. Clement Osei. I am trying to get a Javascript "script" to do a function for me. I am trying to write a a script that will run while the webpage is open, that is selected a randomized 9 digit number Less than 350000000 that will be put into a textbox and submitted. I want a adjustable time when it submits. Could this be made into an <iframe>? Also, this has to do it to a different website, not the one locally being opened. Thank you for your help. Hi, I have a jsp which has a function gets called during the page unload. This jsp has a form with an action attribute to one servlet. Please find below the code snippet. ---- Java script code --- function logoff() { document.forms["FormName"].rel="nofollow" target="_self"; alert('Submitting the form'); document.forms["FormName"].submit(); } --- HTML form code ----- <body onUnload='logOff()'> <form name ="FormName" method="POST" action='<%=sLogoutResponseURL %>'> Whenever the page gets unloaded always logoff function is getting called. I also get the alert message "Submitting the form". But my servrlet does not get invoked. My application supports logging in with the same user id more than once. Scenario it works: User logs in. Close the application. logoff function is called and servlet gets invoked. Scenario it does not work: User logs in one window. Open one more IE window and and open the application with same user id. this can be repeated. Now when i close the application logoff function is called for all of the window close. But servlet does not gets invoked all the time. Sometimes it stops calling servlet. I have searched over the net and found one solution. Below piece of code will make sure form gets always submitted. -------------------------Start ----------------- function fakeSubmit(event) { var target = event ? event.target : this; /* Fire a submit event */ var fakeEvent = $(target).fire("form:submit"); if (fakeEvent.stopped == false) { /* Call the real submit function */ this._submit(); } } if(window.HTMLElement){ /* DOM-compliant Browsers */ HTMLFormElement.prototype._submit = HTMLFormElement.prototype.submit; HTMLFormElement.prototype.submit = fakeSubmit; } else { /* IE does not expose it's HTMLElement object or its children Let the document load so all forms are accounted for */ document.observe("dom:loaded", function(){ for(var i = 0; i < document.forms.length; i ){ document.forms[i]._submit = document.forms[i].submit; document.forms[i].submit = fakeSubmit; } }); } -----------End ------------------ But this resulted in script error while loading the page "object does not support this method or property" at line where document.observe is there. Kindly help at the earliest. Thanks in advance Santosh I need this code to calculate the sales tax when you hit the submit button and I can't get it to work.

My AJAX query returns me an XML response of the following structure for a query on "ind": <countries> <country> <name>India</name> <capital>New Delhi</capital> </country> <country> <name>Indonesia</name> <capital>Jakarta</capital> </country> </countries> How do I transform the XML response into a HTML layout? Particularly, how do I get down to the value at each node?How do I traverse the XML document using JS? Is this (using XML) better than JSON (other than the obvious platform-independence)? Which is better? Thanks! Hi all Is using the real form submit button a problem in any way? Can it actaully send a form when a person uses 'enter' in a text field. When I use this submit, it triggers my validation which is great. Code: <input type="submit" value="OnSubmit validate" /> However this way doesn't seem to trigger my validation although It may solve the above form send problem (if that realy exists). How do I get it to act the same as real submit so it will trigger validation like onsubmit above? Code: <input type="button" value="Send Feedback" onclick="this.form.submit()" /> LT does any of that make sense? all ideas helpful and appreciated I've got the following 2 fields in my form: <input type="file" name="filename" id="filename" value="filename"> <input type="submit" name="submit" value="Upload Image" /> Now I want to hide both of them as soon as the submit button is pressed. Problem is that I'm a javascript noob and I can't find it with google :S Can someone help me? I have created some online software which uses form data to submit to another page. The problem is that I have other submit buttons in the same form which submit to different pages (depending on which button is pressed). The first submit button works fine but all the others only work once. Code: <input class="cssbutton" type='submit' value='Button1' onclick="wbform.action='page1.php'; target='mainFrame'; return true;"> <input class="cssbutton" type='submit' value='Button2' onclick="wbform.action='page2.php'; target='_blank'; return true;"> <input class="cssbutton" type='submit' value='Button3' onclick="wbform.action='page3.php'; target='topFrame'; return true;"> <input class="cssbutton" type='submit' value='Button4' onclick="wbform.action='page4.php'; target='topFrame'; return true;"> <input class="cssbutton" type='submit' value='Button5' onclick="wbform.action='page5.php'; target='_blank'; return true;"> <input class="cssbutton" type='submit' value='Button6' onclick="wbform.action='page6.php'; target='_blank'; return true;"> Any ideas my friends? Hi all, I'm new to php, but managed to get a domail.php working. My form from my html website is sent by the php file to my email address. However, the php echoes a mailresult upon successful sending, but how can I let my website respond to this mailresult?? I'd like to go to a different page, when the mailresult==OK, so something in my html file like if($mailResult==OK){ //go to page saying, your mail has been sent! } OR I could change the "OK" to something more like "Thank you, your mail has been received" in the php file, because this text IS shown in my browser window. Then I would need to know how to make the layout of the window saying this fit my website layout, because now the text is just in a white plain frame.. Hope you guys can help me with either of those two options. Thanks a ton!! Jay Hi Guys, I am having a small problem in my Javascript when I am using HTTPRequest. I am unable to recieve my Response back from server (Java Servlet) in time. I am using following code; Code: // Following function will simply goes to the Server and check if provided class is present
function verifyClass(clsName)
{
var url = "checkServlet?className=" + clsName;
var chkResult = "";
var httpReq = null;
// Create an ActiVEX control object according to BRowser we are using
httpReq = GetXmlHttpObject();
if (httpReq == null)
{
alert ("AJAX Request Failed!!! - Your browser does not support AJAX - Skipping CLASS Check.");
}
else
{
// First prepare ourself to recieve a response from server
// Following code will simply wait untill server finish its response
httpReq.onreadystatechange = function(){
if(httpReq.readyState == 4){
chkResult = httpReq.responseText;
}
}
// Setup a request parameters
httpReq.open("GET", url, true);
// Send the request
httpReq.send(null);
}
// Return the response recieved
return chkResult;
}
I am using FireBug (plugin with my Firefox) to debug the HTML and I can see the response in it but when I am putting 'alert' before return the variable 'chkResult' is empty. Your suggestion will be appreciated; Thanks, -- SJunejo Hello, Im just starting out with java script. I have written the following statement, and for some reason it does not follow up beyond the prompt command. As i type in yes or no - the screen empties. Id be happy if you could tell me where i had gone wrong. My guess its something about the syntax. <!DOCTYPE html> <html> <title>ex</title> <head> <script> var question1 = prompt("do you want to hear a story?"); if (question1 = "yes") {console.log ("once upon a time there was a dragon");} else { console.log ("Maybe listen to a little music?");} </script> </head> <body></body> </html> Hey guys, I am doing a website and the way it is suppose to work is when you click on a link there is a little triangle beside it, so when you click on it the triangle is suppose to face down but more links appear when you click on it.

i have a drop down which triggers a ajax call. The ajax response is a form with various fields depending upon the drop down option selected. I have a text field in that response form which is to input the date. i have a calender widget and wish to display that as a popup with an onfocus or onclick on that text field. But becoz of the ajax response it does not let me do it. I know the problem is in the creation and destruction of the element where the calender has to be displayed so i tried putting the callender intiialization function in another function and calling that onclick but id doesnt work. below is my modified javascript code for the initialization of the calendar. Code: <script type="text/javascript">
var calendar1, calendar2, calendar3; /*must be declared in global scope*/
/*put the calendar initializations in the window's onload() method*/
function cal_init()
{ alert("hi");
calendar1 = new Epoch('cal1','popup',document.getElementById('calendar1_container'),false);
calendar2 = new Epoch('cal1','popup',document.getElementById('calendar2_container'),false);
calendar3 = new Epoch('cal1','popup',document.getElementById('calendar3_container'),false);
};
</script>
Hello All, I have a string array in a class file that contains 5 values, which I need to display on the jsp page. but when I send it to the javascript it prints [Ljava.lang.String;@104f8b8 . what do i do about it. I am a new to javascript. Is there a way to get my array data from the response object. Please help. I'm make a ajax call to a processing PHP file that echos either "success" or an "error message". When the success is returning, i want Jquery to recognize this and then redirect the browsers instead of displaying the success message. Here are some snippets. I can only seem to parse to a blank or null. Jquery code: Code: $.ajax({
type: "POST",
url: "process.php",
data: wfLoginPost(),
success: function(msg){
alert(msg);
// both below are either null or blank
//var res = $(msg).find("span.response").text();
//var res = $(msg).find("span.response").html();
if(res == 'Success'){
window.location = 'http://www.google.com';
}
}
});
process.php PHP Code: if($qry[0]['pwd'] == $password){ echo "<span class='response'>Success</span>"; }else{ echo "<span class='response'>Username or password did not match</span>"; } Here is the contents of the msg response from the ajax post: Code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
