JavaScript - Button Onclick Event Not Firing
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>
Similar TutorialsI 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']."

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.... 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. hi, i have aded window unload event handler to my code. my page calls some function that takes few secs and page then loads in 5-6 secs. while ths page is loading, if user clicks 'x' on browser window, then code inside unload event handler doesnt get executed. if user waits for page to be loaded fully and hten clicks 'x', then unload event handler gets executed. but i want if during loading user decides to click 'x' button, then also unload handler shold get exucted. i am pasting a sample code that simulates my situation: <html xmlns="http://www.w3.org/1999/xhtml" > <head> <title>Untitled Page</title> <script type="text/javascript"> function unloadPage() { alert('unloaded page'); } function pauseJS(timeInMilliS) { var date = new Date(); var curDate = null; do { curDate = new Date(); }while(curDate-date < timeInMilliS); } </script> </head> <body onload="pauseJS(6000)" onunload="unloadPage()"> <p>Test Page</p> </body> </html> I have an input text with an onchange event that calls a function in which an alert box displays. I also have a button whose onclick calls a different function. If the user makes a change in the input text and immediately clicks the button, the onchange event fires, displaying the alert box, but the code in the function for the onclick of the button doesn't execute. I've read that this has something to do with event bubbling, but I haven't seen any solutions. Is there a solution? Is it even possible?
Hi All, I have a script that is called by the onchange event on my text field (it compares the date entered into the field and issues an alert if the date is earlier than the current date). This worked great on my data entry form but I also want to use the same script in my update form. In the update form the text field is already receiving a value via php: Code: <input name="DateNeeded" type="text" class="formField" id="DateNeeded" onchange="checkDate(this)" value="<?php echo $row_rstRequestDetails['DateNeeded']; ?>" /> and this is causing my onchange event to fire when the page is loaded. Is there a way to suppress the onchange event for the initial page load? Thanks, Ken Hello, I'm working on a quote generator and I'm running into an issue with onChange events not firing when a text field is dynamically populated via a child window. Here's my setup: I have 3 text boxes (quantity, price, markup) that are multiplied together in order to give the total of that product. Each text box has an onChange event [called calculator()] that calls an external javascript file, which handles the multiplication and instantly updates the total of that product. Up to this point, everything works fine - - when I manually edit any of the 3 inputs, the total updates correctly. However, my problem is that I now have the "price" text box being dynamically populated, and when it updates it is not firing the onChange event attached to it. The text box is being filled by way of launching a child window and running the following code within it: Code: function call_submit()
{
opener.document.quote_form.item_price_1.value=document.child.prods.options[document.child.prods.selectedIndex].id
self.close();
}
I've also tried to call the calculator function from within the child window, with no luck: Code: function call_submit()
{
opener.document.estimator_form.item_price_1.value=document.child.prods.options[document.child.prods.selectedIndex].id
calculator ()
self.close();
}
So, as of right now, the following is happening - - I launch the child window, I select the product to add to the quote, the child window closes and the price is correctly populates within the "price" text box, BUT the total stays at zero. If I manually edit any of the fields, it then catches back up and properly updates the total. Is their any way to fire the onChange event at the time when the text field is populated from the child window? Any help would be appreciated. Thanks in advance. Hello forum, My name is juan and recently started html programming. I have a web page with a drop box with the name of states. Code: <option value="">Alabama</option> <option value="">Alaska</option> I can add a onclick="code here" to the tag so that when the drop box alabama is selected it triggers the onclick event. Im using Ibox in order to have a image of the state open. Code: <a href="images/large/image_1b.jpg" rel="ibox" title="alabama at 1024x450!"><img src="images/small/image_1.jpg" alt=""/></a> the above is a <a> link tag correct? How do I go bout adding the above code into the onclick event? Hi, New to javascript. Doing web page with ASP/VB.NET. Have text boxes for UI on page. Two command buttons - Submit (for db update) and Cancel. I need the Cancel button to prompt the user to verify cancellation. Need OK/Cancel buttons on alert. If user selects Cancel-no action. If user selects OK then I want the text boxes cleared of user text input and focus returned to first text box. I think this may be the code but do not know how to apply it. function Clear() { var res=window.confirm("Please confirm cancellation-text boxes will be cleared"); if(res==true) { document.getElementById("StrtDte").value=""; document.getElementById("EndDte").value=""; document.getElementById("txtProjRegHrsAl").value=""; document.getElementById("txtProjOTHrsAl").value=""; document.getElementById("ddlRAS").focus(); } } Is this code valid or invalid for the events I need? How do I set it to fire when user clicks the ASP Cancel button? Thanks, John I've got a checkbox that, when clicked, displays new text inputs. However, when I "uncheck" the box, the fields don't disappear unless I reload the entire page. What code can I add to reset the box to null when it is unchecked? Here's the function code I have: Code: <script>
function showUserReg() {
document.getElementById("userReg").style.display = "inline";
}
</script>
And here's the inline code: Code: <input type="checkbox" name="additional" value="userRegister" onclick="showUserReg()"/> Yes! Register me now!<br/> <span id = "userReg" style="display:none"> <table class="nobord" align="center"> <tr> <td>Choose a username:</td> <td><input type="text" name="username" size="35"/></td> </tr> <tr> <td>Choose a password:</td> <td><input type="password" name="password" size="35" maxlength="20"/></td> </tr> <tr> <td>Confirm password:<font color="red">*</font></td> <td><input type="password" name="password" size="35" maxlength="20"/></td> </tr> </table> </span> Thanks for any help. hi, i need to be able to take the values from two text boxes and change the location of a sprite on my canvas, i've searched the internet and it doesnt really explain how to do it for me. here is my code: x: <input type="text" name="x" id="x"/><br /> y: <input type="text" name:"y" id="y"/><br /> <input type="submit" value="Submit" onClick="ChangeCo()" /><br /> function ChangeCo() { } and i need the function to take the x and y values from the text boxes and change the values of my variables: var block_x; var block_y; block_x = 290; block_y = 70; Thankyou in advance here the deal ,,I've solved all but this problem in my script i have my page setup with 1 iframe and the main html the code below is exactly how the page will show up in the iframe, you can copy and paste the whole thing and save it as a htm file to view if needed.. I need a way to catch the clicks that happen within the iframe but from the main section of the page..heres why! this is inserted at the top of the page if(top.location==self.location){top.location="RefESI_search.asp";} just above top.document.reset.RefCat.value= I can get the page to load even with this in the iframes ..but for the purposes of this i left it out so the page would load ok for anyone thats gonna try and help . theres only 2 links in the code.. hopefully whatever will hopefully solve this problem will be able to tell which links were clicked,and i can can point them to the apropriate links.

I assum the following html code: <div id="id1" onclick="click()">A<div> <div id="id2" onclick="click()">B<div> Do you know how to get ID = id2 when I onclick on A? I was trying to help someone on another forum and seem to have run into a brick wall. The main problem that has got me stumped at the moment is that clicking on the images in the 1st tab work fine. However the subsequent tab selections and clicks do not change the "bigImage" correctly (not at all). Perhaps some other more experienced forum members can identify what I doing wrong at this time. I believe it is in my set-up of the onclick events in the "onload=" section, but I not the best at this event stuff yet! Code: var sel, tmp, elem;
var j=0;

Hi, I am trying to get my onclick event to handle both of the function below. I want the event to return false (stop executing) if any of the two functions return false. Here is my code: Code: function isNumeric(elem, helperMsg){
var numericExpression = /[0-9]+/;
if(!elem.value.match(numericExpression)){
SaveRecord();
return true;
}else{
alert("You cannot enter numbers in the Comments field.");
return false;
}
}
function lengthRestriction(elem, min, max){
var x = elem.value;
if(x.length >= min && x.length <= max){
SaveRecord();
}else{
alert("Please enter between " +min+ " and " +max+ " characters in the Issue Number field");
}
}
Please help me. Thank you. Hi I would like to use javascript to control what tooltip displays when a tab is rolled over depending on which tab was clicked. Code: <li id='1tab_1a' class='selected'><a id='1link_1a' title="Customer Info Screen"><span >Customer Info</span></a></li> <li id='1tab_1b' ><a id='1link_1b' title="Order Detail" ><span>Order</span></a></li> <li id='1tab_1c' ><a id='1link_1c' title="Phone Detail" ><span>Phone: 7093521232</span></a></li> For example when the Customer Info tab is selected I would like the tooltips to be like above but when Order is the tab selected I would like the tooltip to say Customer Info Detail, Order Detail Screen, and Phone Detail. How could I use an onclick event to control what tooltip is being displayed depending on which tab is selected? I have about 20 sets of customer info and sometimes not everyone contains all of the tabs and I would also like to be able to add more customers. I'm having an issue where a programmatic click event is not behaving the same way the cursor click event is. A cursor click returns the correct object from GetObject(). The programmatic click triggered by a USB device is returning undefined from GetObject(). How can this be resolved? Edit: It appears that it does not recognize eval(document.getElementById(gButtonList[gButtonId])).onclick(); as an event. Why is this? How can I get it to recognize it? Edit2: Resolved it myself. See green text below. TestPage.htm: Code: <script language="JavaScript" src="../bin/USBHelperFile.js"></script>
<script language="JavaScript" type="text/JavaScript">
function BuildButtons()
{
for (var i = 0; i < testArray.length; i++)
{
// Create Div [Buttons created programmatically]
var divNode = document.createElement('div');
divNode.id = 'div' + i;
divNode.onclick= ClickFunction;
etc...
}
}
function ClickFuntion(nodeButtonNum)
{
alert(GetObject());
Returns the index for a cursor click. Returns undefined for
the programmatic click triggered by the USB device
}
function GetObject()
{
var node = event.srcElement;
return node;

i m very new to this thread so i will try to be as clear as possible i m try to create a website where i n have inserted a menu (this menu template i found online which is free.) Code: <div id="menu">
<ul class="menu">
<li><a href="#" class="parent"><span>Home</span></a>
<li><a href="#"><span>Cities</span></a>
<div><ul>
<li><a href="#"><span>Pune</span></a></li>
<li><a href="#"><span>Mumbai</span></a></li>
<li><a href="#"><span>Delhi</span></a></li>
<li><a href="#"><span>Madras</span></a></li>

<li><a href="#"><span>Login</span></a></li>
<li><a href="#"><span>About Us</span></a></li>
<li class="last"><a href="#"><span>Contact Us</span></a></li>
</ul>
</div>
what i am trying to do here is when i click on city (one of the menu) it should read the values from database table (the table name is cityCode. this table contains two rows first cityName and second cityCode) n depending on which city is selected it should retrieve the code of that city. also where to save that retried value because i want to use that retried code to extract value from another table. Hi Everyone, How would i add an avent listener to change the source of an image? I have added the image to a canvas element through javascript using the code below. Code: var start = new Image(); start.src = "start.jpg"; ctx.drawImage(start, 50, 50); Thanks! Is it possible to have an onclick event on a readonly input field? I want to avoid the mouseover event.
Hi all, I can't seem to add an onclick event to an image. I'm sure I am doing something wrong as I am very new to Javascript. This is a part of my javascript code that is in the head and body of my HTML file: Code: <head>
<script language="JavaScript">
.....
.....
var redLocation0 = redArray[0]+".jpg";
....
....
function redClick( buttonLocation ) {
window.location = "http://www.yahoo.com/"
}
....
....
</script>
</head>
<body>
<table>
<tr>
<td>
<script language="javascript">document.write('<IMG SRC="'+ redLocation0 +'">'); onclick="redClick('0')";</script>
</td>
</tr>
</table>
</body>
The image that is displayed is not clickable, and therefore the function redClick cannot be called. Can someone please help me and tell me where I am going wrong here. I am kinda new to JavaScript. Thanks! |
