JavaScript - How To Handle Reload Button Event Or Block It
Hi
I am generating a report on submit click.Due to size of data query execution takes some time to display result, in mean time if user press reload button on browser toolbar consequently same query request going to database and the performance become slow down. I am able to restrict user from clicking F5 and ctrl+R button but not reload button. I there any way to handle event on reload button? or can we disable reload button on submit? Thanks in advance! Similar TutorialsI have cpa gateway on a site that when the customer completes a function of the gateway. The external js of the gateway sends a command to the website to reload the site. Is there any way I can have some sort of event listener to know if that command is sent or not? The problem I'm having is its causing a loop in my existing JS. So it keeps looping the page. I would like to be able to set a cookie when the command is sent and then just have the cpa gateway not load. Thanks all! I haven't been on here in awhile so I have been learning a lot on my own! But this one stumps me Eric. Sorry if this is the wrong place for this question, but... I'm having an issue with the difference in behavior between the IE and FF back buttons. I'm using jQuery to create collapsable div regions which contain text boxes on a search form. After submit, if the use clicks the back button in FF, the region(s) the user had previously expanded, show as expanded. Also, there search term is still present. In IE, when clicking the back button, all regions are collapsed, in there original loaded state, but the search term is still saved. I put the following code at the top of the page: onload=function(){ alert('Onload!'); } When clicking the back button in FF, nothing happens. For IE, the alert pops up. This tells me that IE reloads the page (but somehow still saves some things, like the search text). My question is, is there a way to keep IE from reloading when the use clicks 'back'? I will be creating my own 'edit' back button for users to get around this, but I also would like to prevent this from confusing users and causing undesired results. Any help would be greatly appreciated. Hello, I need some script to force the browser to reload/refresh when a page is reached from the back button. EG You're on page A -> You click a link onto page B -> You Press Browser back to go onto Page A, it has old content that requires a reload. Now, my page is currently php so I won't bother with my code here as I am looking for any solution (I have also posted in php forum). Any JS solution that will trigger a reload on browser back is appreciated. I have tried a few ideas, most work in Chrome, IE always works, Firefox 4 and Opera 11 wont reload, simply fetching from cache I believe. Thanks. Hi I am trying to trigger an event once the user clicks the browsers back/forward buttons, I have built a system just like facebook where if the user has javascript turned on they get the full feature of the site which includes fast switching for example if someone goes to this page "example.com/index.php" and click a link to contact.php it would change the url to "example.com/index.php#!/contact.php" but what I need to know is if there is any way to change the pages content when the user goes back and forth through the fast switch pages? something like "history.back !== -1" or something like that. If anyone can help please reply, thank you. Hi, ive just been debugging my script in IE, and came across this: Code: OrbitTool.prototype.handleMouseUp = function(e) {
if (e.button == g_o3d.Event.BUTTON_LEFT) {
this.mouseLeftDown = false;
} else if (e.button == g_o3d.Event.BUTTON_MIDDLE) {
this.mouseMiddleDown = false;
}
};
its giving me an error on the second line, the error reads ('button' is null or not an object). does anyone know why this might be? im not a pro with javascript so my knowledge only stretches so far. Simon Reply With Quote I have identical code in my index that works, so I'm just guessing the error is somewhere else, I know IE is not the best target to aim for - but I really want this to work in the windows default browser.... Here is the php page... PHP Code: <HTML> <HEAD> <TITLE> Family Home Page </TITLE> <SCRIPT TYPE="text/javascript" SRC="AddFamilyMemeber.js"> </SCRIPT> </HEAD> <BODY> <TABLE> <TR> <TD>Father:</TD> <TD> <SELECT ID="Father"> <?PHP $con=mysql_connect("localhost","XXXX","XXXX"); if (!$con) { die('Could not connect: '.mysql_error()); } mysql_select_db("XXXX",$con); $result=mysql_query("SELECT * FROM FamilyMembers"); while ($row=mysql_fetch_array($result)) { echo "<OPTION VALUE=\"".$row['ID']."\">".$row['FirstName']." ".$row['MiddleName']." ".$row['LastName']."</OPTION>"; echo "<BR/>\n"; } mysql_close($con); ?> </SELECT> </TD> </TR> <TR> <TD>Mother:</TD> <TD> <SELECT ID="Mother"> <?PHP $con=mysql_connect("localhost","XXXX","XXXX"); if (!$con) { die('Could not connect: '.mysql_error()); } mysql_select_db("XXXX",$con); $result=mysql_query("SELECT * FROM FamilyMembers"); while ($row=mysql_fetch_array($result)) { echo "<OPTION VALUE=\"".$row['ID']."\">".$row['FirstName']."

Code: function Abort()
{
document.location="AddFamilyMember.php";
};
When I load the page everything looks ok, but click on the abort button, and all that happens is that the little error symbol pops in the lower left of IE. The names of the two files are "AddFamilyMember.php" and "AddFamilyMember.js". Sorry, but I honestly can't see where the problem is.... I am using 2 ajax functions in the program. One for login and one for logout. The login one is showUser which is working correctly by using the form onsubmit method, however the logout button (IN BOLD) onclick method is not working. Pls help. Code: <form onsubmit="showUser(document.getElementById('uid').value,document.getElementById('pass').value);return false;" >
<div id="txt"><b>Enter your username </b>
<input type="text" name= "username" id="uid">
<br>
<b>Enter your password</b> <input type="password" name="pass" id="pass">
<br></div>
<div id="txt1" style="display : none">help</div>
<input type="submit" value="Login" />
<input type="button" onclick="logout(document.getElementById('uid').value); return false; " name="logout" value="Logout" />
<input type="button" value="Register" class="register"/>
</form>
Code: Quote: Code: Quote: Code: Quote: can somebody please tell me what need done. Everything is working fine except for the button created in javascript that is in the second window which is to open the third window. Thanks. Greetings, Does anyone know the code to create a function and form to make the position of a button change dynamically based on a mouseover event please? Whereby a viewer's cursor will chase the button around an IE page for infinity! I would prefer to do this without the need for any plugins if at all possible, and it does not need to be cross-platform, just IE is fine. Many thanks Hi forum, I am trying to attach an event to a dynamically produced button, and then use stopPropagation and preventDefault. Code: function chapter12_nodeOne() {
//create an element
var element = document.createElement('input');
//set some attributes
element.setAttribute('type', 'button');
element.setAttribute('value', 'submit');
element.setAttribute('id', 'myBtn');
//appendd the element into a DIV
document.getElementById('myDiv').appendChild(element);
//uses EventUtil to attach an event listener
EventUtil.addHandler(element, 'click', function() {
alert('event attached');
});
var flag = confirm('prevent default behavior of button?');
if (flag) {
var el = document.getElementById('myBtn');/////////////////////////(1)
var ev = el.onclick;
}
}
var EventUtil = {
addHandler: function(element, type, handler) {
//check if the element and the browser support DOM Level 2 event attachment
//if the user is not browsing with IE
if (element.addEventListener) {
element.addEventListener(type, handler, false);
}
//if user is browsing with IE
else if (element.attachEvent) {
element.attachEvent("on" + type, handler);
}
//if user is using a browser that only supports DOM Level 0 event attachment
else {
element["on" + type] = handler;
}
},
removeHandler: function(element, type, handler) {
//check if the element and the browser support DOM Level 2 event attachment
//if the user is not browsing with IE
if (element.removeEventListener) {
element.removeEventListener(type, handler, false);
}
//if user is browsing with IE
else if (element.detachEvent) {
element.detachEvent("on" + type, handler);
}
//if user is using a browser that only supports DOM Level 0 event attachment
else {
element["on" + type] = null;
}
}
};
But when debugging I see under el on the line marked with (1) that the onclick event is null. What am I doing wrong?! PS:the event is attached, when I click on the button I get an alert message is it possible to capture the control.event or element.event that was fired to invoke the onbeforeunload event. for example, if a button is clicked and it causes the onbeforeunload event to fire can i determine which button was clicked. thanks I have a ondrag event handler and in that I am trying to retrieve e.ClientX but it always return 0 in Mozilla. Works fine in IE though. How can retrieve the clientX and clientY in ondrag event? Hello people, I got a problem. This is the code for hiding en showing informatie in an acordion.

Dear friends, My Function code is: [code] <script language="javascript" type="text/javascript"> //function to create the printer and take variable from button pressed by user function RunEXE(prn) { var oShell = new ActiveXObject("WScript.Shell"); oShell.Run ("%comspec% /k c:\windows\system32\rundll32 PRINTUI.DLL,PrintUIEntry /in /n "+prn+"",2,true); } </script> the variable is passed properly to the function with spaces using below form button. But, the command in the function doesnot execute after the space, that is printer name is taken as "5E-" only. How do i pass prn variable with additional double quotes, so that command in function takes it in full including spaces. thanks so much.

If i have a address like this 255.255.255.255, my program jumps into the next text box without any problem as soon as i enter the 3 digits. i dont need to press any tab or any other key to go to next text box. In case of an address like 12.24.12.3, i have to press <tab> to jump into the next text box, My project requirement says that it should work with '.' (dot) char as well.
