JavaScript - Unable To Login On First Visit
Hello.
I'm trying to set up a login formular with PHP and JavaScript/jQuery. Currently it sends an alert box, if some information are wrong. If correct, it refreshes the page, and everyone's happy. However, I noticed upon the first visit, I cannot log in. Lets say I go to www.mysite.com and try to login, it displays a blank alert box, when it's suppose to display the username, that I supplied, and is wrong... however, it's blank. BUT! If I go to another page and login with false informations, an alert box with the wrong username pops up - if I login with correct informations, it works. How come it won't work on first visit? What am I doing wrong here? Pressing F5 won't work either - I have to manually switch to another page for it to work. Any suggestions and ideas are welcome and appreciated. I'll supply the codes necessary for anyone to help me, but at this point I'm completely blank on which of my codes may be the problem. EDIT - IMPORTANT INFORMATION! Now THIS is weird! I just noticed it's because there's not www. in the URL. There has to be www. for it to work, why is this? I forced the client to have www. in the URL with .htaccess, but I'd still like to know, why this problem occurs without it. Similar TutorialsI was trying to display time of last visit along with login name.. can someone help me on this pls? Hello all; I am doing a site for a local business that uses radio advertising and has a jingle that they want to play once per visit only (so it does not play over again of they return to the same page later that day). I have tried to use yahoo player, Google player and the infamous wma player and all work well. I especially like the yahoo player but as will all the players I could not find a way to have it only play once per day per visitor. Is there a way to accomplish this? I was thinking using a tracking cookie but have no idea how to implement it. In the end I would like to accomplish the following: mp3 plays automatically on page load audio only playes once per day per visitor hava small player so if the visitorr wants to hear the jingle again they can do so. the player should be compact and cross browser compatible. Should be compatible with HTML 5.0 Transitional or at the very least 4.01 Any help would be appreciated. Hi all, I'm trying to find what I'm sure is a simple bit of js which I can use that will close a div for the duration of a users visit as it would hide a notice I'd only want to display once on a site. Essentially all I'd want to do is have a simple div with a paragraph and a link to close the div but to have it remember across pages that the user has dismissed the notice. I noticesearched around and found a similar request here but I don't know js enough to replace the inputs in the example to a simple link and to remove the show div functionality. Anyone able to provide me with any pointers on how I'd be able to achieve this? Many thanks, J. I have a site using Grey Box pop up ( http://therdkgroup.com/) . It automatically pops up when you go to any of the 5 pages on the site. Is it possible to add a cookie to it so that it only pop up the first time someone comes to any one of the pages? If so, can you point me in the right direction on how to solve this?? Hi there, I was wondering if there were any scripts (or if you could build be one) which allow first-time visitors to read through step by step tooltips which explain features of a system. For example, users could click on "next" to make that tooltip dissapear, and the next tooltip reappear. ANy help would be great, Thanks Hi! First post here! Would really appreciate some help on a javascript that would display the time elapsed since a particular visitor last visited my webpage, using cookies. So basically it should show something like: "You last visited my page 2 days & 12 mins ago!" I've a little background in java but none in javascript... Thanks so much! <script type='text/javascript'> $(window).load(function () { $('area').each(function (e) { var area = $(this), alt = area.attr('id'); if (alt != null) { area.mouseenter(function () { var newImage = $('<img />'); newImage.attr('src', 'ReadImage.ashx?id=' + alt); // call handler with id $('.display').append(newImage); }; } e.preventDefault(); }); }); </script> <div class="display"> </div> <img src="3rd_Floor_screen-size.jpg" width="1372" height="906" border="0" alt="" usemap="#Map" /></div> <map name="Map" id="Map"> <area id="1" alt="1" class="tooltip" shape="rect" coords="28, 87, 93, 181" href="#"/> <area id="2" alt="2" class="tooltip" shape="rect" coords="95, 91, 172, 158" href="#"/> <area id="3" alt="3" class="tooltip" shape="rect" coords="175, 90, 225, 157" href="#"/> </map> I am gettting image on mouseover, if i over the mouse on area id =1. That id 1 will be passed to the ashx page through the script. The ashx page returns my image from the database. I am loading that image in the div display. Now what i need is i have to display the image as a tooltip not in a div........ For example: Visit this following website. http://visitmix.com/labs/glimmer/samples/tooltip.html Can anybody suggest me a solution to do this? I know there is an easy way to do this...... i have brought 60 percent. Now what i need is i have to get this image as a tooltip when i move the mouse over the area id =1.. Thanks Hi everyone. New to javascript here.... I have a problem here. I know how to store a cookie and check a cookie... but i don't know how to calculate the time between current visit and previous visit... Example. I logged in @ 1pm and logged in again @ 3pm... It should a msg like "your last visit was 2 hours ago" Can any one enlighten me ? Thank you! Can a random page be loaded without a prior visit to a site? I have a list of 15 people with a photo and contact information in a table with 3 columns and 5 rows. The issue is that the people near the bottom want a chance to be at the top the first time the page is viewed. It is unlikely that a second visit would happen. Is this possible to load a random page for a site without it being viewed or logged into before, therefore no cookies will be used. My knowledge of Java script code is limited so any help would be great. Thanks Motty Hello there guys! Thanks for taking time to view this thread. It's appriciated! I found a really nice menu (Javascript, JQuery) im not so high tech on this myself, and not the best coder either but whenever I use this menu it gives the login box on the website an error, it doesn't let people login.. I've tried to localize the error myself, but I just dont know how to fix it, I think the issue is that the site system i use doesn't support these type of scripts which gives the login errors! I'm currently using a free website system, which allows you to customize anything you want called "uCoz" The menu i used was: http://www.dynamicdrive.com/dynamici...enu-glossy.htm And I think it's the jquery that gives the login box errors.. I'm thankfull for answers if anyone knows Hello everyone. I have a a html page that is used as a login page. I know it is not secure but this is just for learning purposes, I'm not using it for anything important. My problem is that when I put in the correct login all that happens is the page just clears the text boxes as if you were starting over. I am trying to get it to go to register.html which is located in the same directory as the login page. Help with what I'm doing wrong would be greatly appreciated. Here is the code: Code: <html>
<head>
<title>Login Page</title>
</head>
<body>
<script type = "text/javascript">
var count = 2;
function validate() {
var un = document.myform.username.value;
var pw = document.myform.pword.value;
var valid = false;
var unArray = ["Philip", "George", "Sarah", "Michael"]; // as many as you like - no comma after final entry
var pwArray = ["Password1", "Password2", "Password3", "Password4"]; // the corresponding passwords;
for (var i=0; i <unArray.length; i++) {
if ((un == unArray[i]) && (pw == pwArray[i])) {
valid = true;
break;
}
}
if (valid) {
alert ("Login was successful");
window.location = "register.html";
return false;
}
var t = " tries";
if (count == 1) {t = " try"}
if (count >= 1) {
alert ("Invalid username and/or password. You have " + count + t + " left.");
document.myform.username.value = "";
document.myform.pword.value = "";
setTimeout("document.myform.username.focus()", 25);
setTimeout("document.myform.username.select()", 25);
count --;
}
else {
alert ("Still incorrect! You have no more tries left!");
document.myform.username.value = "No more tries allowed!";
document.myform.pword.value = "";
document.myform.username.disabled = true;
document.myform.pword.disabled = true;
return false;
}
}
</script>

Hi guys, My brain is not working. May be I need a coffee break. I need your expertise. Below is the code holding the textarea. Look for the element with the id : themessage Code: <table width="100%" border="0"> <tr><td rowspan="4"><input type="button" name="send_email" id="send_email" style="height:50px; width:100px;" value="SEND" onClick="return err_check();" /></td><td><span class="que">From : </span></td><td colspan="3"><?php echo $from_email; ?><input type="hidden" name="from_mail" id="from_mail" value="<?php echo $from_email;?>"/><input type="hidden" name="camp_id" id="camp_id" value="<?php echo $camp_id;?>"/></td></tr> <tr><td><span class="que">To : </span></td><td colspan="3"><input name="to_email" id="to_email" style="width:250px;" /></td></tr> <tr><td><span class="que">CC : </span></td><td colspan="3"><input name="cc_email" id="cc_email" style="width:250px;"/></td></tr> <tr><td><span class="que">Subject : </span></td><td colspan="3"><input style="width:300px;" name="subject" id="subject" /></td></tr> <tr><td rowspan="1" colspan="2"> </td><td><input type="checkbox" name="ori_pdf" id="ori_pdf" /> PDF Quotation</td><td> </td><td> </td></tr><tr><td colspan="2"><span class="que">Credit Application</span></td><td><input type="checkbox" name="corporate" id="corporate"/>Corporate</td><td><input type="checkbox" name="individual" id="individual" />Individual</td><td><input type="checkbox" name="cash" id="cash" />Cash Account</td> </tr> <tr> <td colspan="2" rowspan="3"></td><td><input type="checkbox" name="tabloid" id="tabloid" />Tabloid Example</td> <td><input type="checkbox" name="broadsheet" id="broadsheet" />Broadsheet Example</td></tr> <tr><td><input type="checkbox" name="colmt" id="colmt" />Column Sizes Tabloid</td> <td><input type="checkbox" name="colmb" id="colmb" />Column Sizes Broadsheet</td></tr> <tr><td><input type="checkbox" name="maps" id="maps" />Maps / Distribution</td><td colspan="2" align="right">External Attachments <input id="upload_file" name="upload_file" type="file"/> </td></tr> <tr><td colspan="2"><span class="que">Message :</span></td><td colspan="3"> <textarea id="themessage" name="themessage" rows="15" cols="80" style="width: 100%"> </textarea> </td></tr> </table> Now on a button click, I'm trying to pass some values which one of them happens to be what ever that is entered in the textarea. For some reason, the stupid JS is not reading. But I think it is me that is stupid, not JS. Below is the code i'm running to get the value. Code: var message = document.getElementById('themessage').value;
alert(message);
The alert simply returns blank. There is an alert, but no value even where there is text in the text area. Can someone please shed some light on this. pretty please Hi all! I created a form where users are allowed to delete a specific row of data by clicking the "cancel" button from the drop down menu. However, I have a problem deleting my data using the javascript. Apparently, I only able to delete the first row of the data but not for the rest! The following is the code i have: PHP Code: <html> <body style="background-color:#E0FFFF;"> <script language="javascript" > <!-- hide function submitRequest(val) { document.forms[0].submit(); } // end hide --> </script> <?php $con = mysql_connect("localhost","root",""); if (!$con) { die('Could not connect: ' . mysql_error()); } mysql_select_db("my_course", $con); $result = mysql_query("SELECT * FROM Courses ORDER BY Year, Sem, CourseCode"); $result1 = mysql_query("SELECT * FROM Courses ORDER BY Year, Sem, CourseCode"); echo "<table border='1' cellpadding='2' cellspacing='0'> <tr> <th>CourseCode</th> <th>CourseName</th> <th>Year</th> <th>Sem</th> <th>Grade</th> <th>Option</th> </tr>"; ?> <?php while($row = mysql_fetch_array($result)) { echo "<tr>"; echo "<td>" . $row['CourseCode'] . "</td>"; echo "<td>" . $row['CourseName'] . "</td>"; echo "<td>" . $row['Year'] . "</td>"; echo "<td>" . $row['Sem'] . "</td>"; echo "<td>" . $row['Grade'] . "</td>"; echo "<td>"; ?> <?php ?> <form name="form1" action="submitDelete.php" method="post"> <select name="cancel" onchange="submitRequest(this.value);"> <option value=> </option> <option value="<?php echo $row['CourseName'];?>">Cancel</option> </select> </form> <?php echo "</td>"; echo "</tr>"; } echo "</table>"; mysql_close($con); ?> <br/> <br/> </body> </html> Thanks in advance! http://jsfiddle.net/FZ44M/3/ Thats my jsfiddle. I'm trying to get the gallerynav to sort the thumbnails based on their class. It does not work at all. I've gone over line by line but I can't see the mistake. When I run JSLink i get the error: Error: Problem at line 37 character 14: Cannot set property 'first' of undefined Implied global: $data 13,14, arr 14,15,25, jQuery 28, $ 30 Unused variable: read_button 30 "$", r 32 "read_button" I appreciate any help. I am restarting a thread because as a result of acting on all of the suggestions I have received the nature of the issue has changed. I am trying to create a button and add it to the DOM under IE7. The code works fine under Firefox: Code: var editButton = document.createElement("button");
editButton.name = "editCitation" + rowNum;
try {
editButton.type = 'button';
} catch(e) { // IE7 throws this exception
alert("citTable.js: gotAddCit: unable to set type for <button name='editCitation" + rowNum + "' type=" + editButton.type);
}
editButton.onclick = editCitation;
editButton.appendChild(document.createTextNode('Edit Citation'));
td1.appendChild(editButton);
I am creating a <button> rather than an <input type=button> because a <button> permits HTML in the button label. Most of my buttons support Alt keyboard shortcuts, so I want to underline the appropriate letter in the label. According to the HTML 4.01 specification, which is as close to a standard as IE7 supports, a <button> can be one of three types: submit, reset, or button, and the default is submit. Since I wish to create a <button type=button> I therefore, at least theoretically, need to be able to set the value of the type attribute. However IE7 throws an exception at that point, although, interestingly, when I interrogate the value of editButton.type in the catch it is set to button. So how do I reliably set the type of a button under IE7? I'm relatively new to javascript and I'm having some issues in adding linebreaks i.e. working <br> tags via DOM manipulation. An example of where I cant get it to work is included in the function code below. The html file the script is used in contains one div with an id of pfield. If its helpful the full program is available at http://www.templeofmick/wumpus3.htm Code: function printHints() {
var vFlags = [0, 0, 0]; //Wumpus, Pit, bat
var wFlag = 0; //Use flags to insure each hint isnt printed multiple times
var pFlag = 0;
var bFlag = 0;
var node;
var i;
var pbreak = document.createElement("br");
var turnP = document.createElement("p");
var idString = ("turn" + turn);
turnP.setAttribute("id", idString);
document.getElementById("pfield").appendChild(turnP);
for (i = 0; i < 3; i++) {
vFlags = checkRoom(currentMap[currentRoom][i]);
if (vFlags[0] === 1) {
wFlag = 1;
}
if (vFlags[1] === 1) {
pFlag = 1;
}
if (vFlags[2] === 1) {
bFlag = 1;
}
}
node = document.createTextNode("You are in room " + currentRoom + ".");
document.getElementById(idString).appendChild(node);
document.getElementById(idString).appendChild(pbreak);
node = document.createTextNode("From here you can travel to room : " + currentMap[currentRoom][0] + "," + currentMap[currentRoom][1]
+ " and " + currentMap[currentRoom][2] + ".");
document.getElementById(idString).appendChild(node);
document.getElementById(idString).appendChild(pbreak);
if (wFlag === 1) {
node = document.createTextNode("The acrid stench of a nearby wumpus fills your delicate nostrils.");
document.getElementById(idString).appendChild(pbreak);
document.getElementById(idString).appendChild(node);
}
if (pFlag === 1) {
node = document.createTextNode("The whistling of the wind indicates that floors are in short supply nearby.");
document.getElementById(idString).appendChild(pbreak);
document.getElementById(idString).appendChild(node);
}
if (bFlag === 1) {
node = document.createTextNode("You can hear the mailicious gossiping of giant bats coming from a nearby room.");
document.getElementById(idString).appendChild(pbreak);
document.getElementById(idString).appendChild(node);
}
node = document.createTextNode("What now ? (M)ove or (S)hoot");
document.getElementById(idString).appendChild(pbreak);
document.getElementById(idString).appendChild(node);
}
edit: I further identified the problem. Hi, I'm new to JavaScript and I'm having problem with appending a div node returned from a function. Here's where it crashed: Code: var div=document.getElementById("dashboard_secondary_cat_list");
var s=get_secondary_cat_node(attributes);
alert("b4 appendin:"+s);
div.appendChild(s);
alert("done appendin");
alert("done appendin"); never gets called because the previous line crashes. alert("b4 appendin:"+s); shows: b4 appendin:[object HTMLDivElement] http://www.codetoad.com/javascript/e...rm_element.asp I tried to use the code in the above link but it is not changing the button to enabled. http://realistichostings.com/b/searc...?cat=Adhesives when i change the value in the select i am wanting the 'add' button to become enabled. i get the following erro in eror console.. Error: missing ; before statement Source File: http://realistichostings.com/b/searc...?cat=Adhesives Line: 1, Column: 14 Source Code: document.form1.3552.disabled=false; This is my first time posting, so please let me know if I am doing things as expected. When users click on a "Was this helpful?" link, an e-mail message displays with the page title (accomplished using a JS function). I want to put this is an external file so that it only needs to be updated once. Here's the code in the feedback.js file: Code: function feedback()
{
mail_str = "mailto:feedback@company?subject=Page Title: " + document.title;
mail_str += "&body=Thank you for your input.";
location.href = mail_str;
}
And here's the code in the page: Code: <script src="feedback.js" type="text/javascript"></script> ... Was this topic <a href="javascript:feedback()">helpful?</a> When I do this, an "object expected" error displays. When I put the code inside of the header, it works fine. What gives? |
