JavaScript - Onchange Event Not Firing When Input Is Populated From Child Window
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. Similar TutorialsHi 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 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> Hi all, I have a HTML and I am opening another link in a separate window using window.open() . The child window is something like 'http://yahoo.com' which is out side html. I need to refresh the parent window when the child window is closed. any idea? Thanks, Mahesh Hi all can someone guide me (total JS newbie) on this presumably pretty easy task? I have a "parent" page with some text inputs in it (a form). This is what I am after: -when the user clicks a link it pops open a new window via JS - "child" (this is working). -in the "child" window there are also some text inputs (another form) (done). -when the user changes the value for 'testChild_textInput_4' in the child window, then I want it to automatically set this same value, to effectively overwrite, what is currently in 'testParent_textInput_2' in the parent window. Presumably this involves an onChange event, but it is also OK with me if the needful (the text input's value in the parent window being overwritten) happens upon the child window's form submit. If anyone can show me either trick, I would be thrilled! I set up a test page to make this all easy to talk about: http://www.yellow-turtle.com/testDumpMe_parent.html Please let me know! Thanks! -John Hello, On a simple form, there is a radio button group with two radio buttons, a text box, and a submit button. The first radio button is checked(selected) by default. The text box input has the onChange event handler so that if the text is changed, the second radio button will be checked(selected). The problem is the input radio name contains a hyphen that breaks the JavaScript and the name can not be changed. What is the correct syntax for referencing a hyphenated form input radio name in the onChange event? Here is the form that works correctly with no hyphen in the input radio name: Code: <form name="myFormGood" action="" onsubmit="return false;"> Good Form with no hyphen in radio button name<br> <input name="radio1" type="radio" value="4" checked> First Option<br> <input name="radio1" type="radio" value="5"> Second Option<br><br> Change the text to select the Second Option<br> <input type="text" name="text1" onChange="document.myFormGood.radio1[1].checked = 'true';" size="10" value=" "><br><br> <input type="button" name="submit" value="It Works!"> </form> Here is the form that breaks the JavaScript because it has a hyphen in the input radio name: Code: <form name="myFormBad" action="" onsubmit="return false;"> Bad Form with hyphen in radio button name breaks JavaScript<br> <input name="radio-1" type="radio" value="4" checked> First Option<br> <input name="radio-1" type="radio" value="5"> Second Option<br><br> Change the text to select the Second Option. Nothing Happens.<br> <input type="text" name="text1" onChange="document.myFormBad.radio-1[1].checked = 'true';" size="10" value=" "><br><br> <input type="button" name="submit" value="It Doesn't Work!"> </form> 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?
I am using 2 ajax functions in the program. One for login and one for logout.

On my site we have image galleries that pop up over top of the page in a higher z-index and position:fixed, and another div between the gallery and background with opacity set to about 85%. The image gallery div has a close button, and I was asked to make the gallery also close by pressing ESC, so I added this: igevt=function(evt){checkclosegal(evt)} window.addEventListener('keypress',igevt, false) and checkclosegal: function checkclosegal(evt) { if(evt.keyCode==27) { closebgeagal() window.removeEventListener('keypress',igevt, false) } } This works perfectly in Firefox and Opera, but Chrome and Safari don't fire the event (not worried about ie right now - I know it uses attachEvent). Could it have something to do with the gallery being in a higher z-index? Please help, thanks! i have this code i need to close the parent.html window when the child window opened, i need the code for that working well in IE and Firefox Parent.html <HTML> <SCRIPT TYPE="text/javascript"> function sendTo() { window.open('child.html','_blank','resizable=yes,width='+(screen.width-500)+',height='+(screen.height-500)+''); } </SCRIPT> <BODY > <form name="form"> <input type="text" value="" name="text1" id="pdetails1"> <input type="text" value="" name="text1" id="pdetails2"> </br> <input type="submit" value="submit" onClick="sendTo()"> </BODY> </HTML> child.html <html> <body> <form> <input type=text name="text5" value=""> <input type=submit name="submit"value="submit"> </form> </body> </html> Hi, I am trying to copy the value of one textbox to another using onchange event.

Thank you. Hi I'm a newbie. Please help me. I'm using Joomla. I've got a dropdown which reads the filename from the database. When the user selects it I want an onchange event to open the pdf. I've been at it for 2 days now. Code: <?php
$con = mysql_connect('localhost', 'root', '');
if (!$con)
{
die('Could not connect: ' . mysql_error());
}
mysql_select_db("metnet", $con);
$sql="SELECT * FROM newsletter";
$result = mysql_query($sql);
echo "<form method='post'>";
$dropdown = "<select name='sname' onChange='location(this.form.sname)' >";
while($row = mysql_fetch_assoc($result)) {
$dropdown .= "\r\n<option value='{$row['fpath']}'>{$row['fpath']}</option>";
}
$dropdown .= "\r\n</select>";
echo $dropdown;
?>
HI, i know very little about javascript, just enough to get me into trouble actually lol. Here is what im working with. I have a custom Instant messenger for members. It uses embed object macromedia as well as javascript to diplay the window and send messages. What i want to do is simply add an onchange that when one person is typing it shows they are typing (ie xxxxx is typing....) My experience is in php and html and i looked thru the script and the javascript functions but im not sure what im looking for exactly. Do i need to have access to the swf or fla file and be able to edit them to do this? I dont see any form inputs or i would know exactly where to put the onchange lol. Im guessing the input is in the swf or fla file not sure how that works. what im guessing is that in the embed or the object tags (ill play with it) i can put something like Code: document.write('test on change\n');
i think i need to wrap that in doc write script type=javascript in quotes so it parses. If i can get that text to show up inside the IM where i want it then i can try to figure out how to set focus on box and recongize onchange and do some testing. I think i might even be able to doc write the onchange command but not sure. Thanks Hi All, I need to show/focus the parent window which is in back when click a link from child window in Chrome.This problem is in Chrome browser only. We have used the below code self.blur(); Window.opener.focus(); But this is not working in Google Chrome. Please suggest me some workaround to achieve this. Thanks in Advance Reply With Quote 12-19-2014, 09:26 PM #2 Old Pedant View Profile View Forum Posts Supreme Master coder! Join Date Feb 2009 Posts 28,311 Thanks 82 Thanked 4,754 Times in 4,716 Posts Window is not defined. window is. JavaScript (and the DOM) is case sensitive. You must pay attention to upper/lower case spelling, carefully. By the way, you shouldn't need the blur() call. If you focus on some window (any window) then any other focus should be lost. I have created and opened a child window called "checkwin" and have written some data to it. If the data is valid, I want the user to click on the 'CONFIRM' button on the child window, at which time I want the "submit()" function for the form on the parent window to be executed. If the data is invalid the user clicks on 'MODIFY' and I want focus to return to a field on the parent form. However, when I click on the "CONFIRM" or "MODIFY" buttons on the child window, nothing happens. Here is the code: Code: checkwin.document.write("</td></tr><tr><td align='right'><input type='button' value='CONFIRM'
onclick='opener.document.personnel_form.submit()'></td><td></td><td><input type='button' value='MODIFY'
onclick='opener.document.personnel_form.first_name.focus()'></td></tr></table>")
After following the instructions from the answer below: http://bytes.com/topic/javascript/an...arent-document I was able to have the child window perform the function defined in the parent window. The function was to only have an alert window pop up as the child page was loading. I easily modified this to my intention which was to have a parent function performed when the child window was clicked. Using the body tag: Code: <body onclick="parent.FUNCTION NAME HERE()"> I first change the method in which the function would be triggered, all went well there. then I tried to change which function would be triggered. (Basically use the function I wanted to happen on click of the child window rather then the function from the test). Once I did this switch, nothing happens. The site this is being used on is: http://tylerpanesar.ca/ What I want is when the menu bar is open in the parent window, the user chooses a link and the menu closes and goes to that link in the child window. This already works. However if the user opens the menu bar and then changes there mind and continues with the page the are currently on (clicks any content in the child window), the menu stays open. Currently the menu "hides" only when you choose one of the menu items, but it does not "hide" when you CLICK on child document. If you could figure out how to get it to "hide" on a "mouse out" that would be the better option. I attempted this method however i could only get it to "toggle" the menu on "mouse out". This method does however create an annoying flicker when you hover over the menu items (as it is toggling the open menu command I guess). If I had it "hide" the menu on "mouse out" it would "hide" as soon as you moved off of the main button. The viewer doesn't even have a chance to click a link. or at least that is what happens when I did it. You may have a better method to achieve this. The script that tells it to hide on click is within a jQuery function: Code: menua
.click(
function(){
menu.hide();
the code I used for the mouseout toggle was: Code: menu
.mouseout(
function(){
menu.toggle();
Here is the script that I am currently using for the menu to open and the "click" hide feature. This menu feature comes from the following help: http://www.bennadel.com/blog/1740-Bu...-FaceBook-.htm Code: <script type="text/javascript">
jQuery(function( $ ){
var menuRoot = $( "#menu-root" );
var menu = $( "#menu" );
var menua = $( "#menu a" );
// Hook up menu root click event.
menuRoot
.attr( "href", "javascript:void( 0 )" )
.click(
function(){
// Toggle the menu display.
menu.toggle();
// Blur the link to remove focus.
menuRoot.blur();
// Cancel event (and its bubbling).
return( false );
}
)
;
menua
.click(
function(){
// Toggle the menu display.
menu.hide();
}
)
;
// Hook up a click handler on the document so that
// we can hide the menu if it is not the target of
// the mouse click.
$( document ).click(
function( event ){
// Check to see if this came from the menu.
if (
menu.is( ":visible" ) &&
!$( event.target ).closest( "#menu" ).size()
){
// The click came outside the menu, so
// close the menu.
menu.hide();
}
}
);
});
</script>
I've tried adding the click to "hide" menu feature to the child document but there is now menu in that document for it to "hide". What I was trying to was have the child document execute a function from the parent document and have that function executed IN the parent document. I've tried the technique from the link in my very first post but I believe it only calls the function from the parent and executes it IN the child. Which does not work for me as the menu is not in the child. There should be a way to make the child execute a function FOR the parent. I apologize for this very wordy post, but I am extremely frustrated with this now as I have been trying to get this to work for a few weeks now. Any help would be greatly appreciated. Thanks in advance, Tyler Hi All, I am really strugling with this and I hope somebody can help me on this. I would like to have a dropdown to only show when a certain value is chosen from another drop down. So if in this dropdown the value ETS Rep Discount is chosen he should show the other dropdown Code: <div class="row"> <div class="fieldName">Discount Type</div> <div class="fieldValue"> <asp:DropDownList ID="discountTypeDropDownList" runat="server" AutoPostBack="True" Width="295px" OnSelectedIndexChanged="DiscountTypeDropDownList_SelectedIndexChanged"> <asp:ListItem Value="<%$ AppSettings:DiscountType.General %>">General Discount</asp:ListItem> <asp:ListItem Value="<%$ AppSettings:DiscountType.Golf %>">Golf Only Rep Discount</asp:ListItem> <asp:ListItem Value="<%$ AppSettings:DiscountType.ETS %>">ETS Rep Discount</asp:ListItem> </asp:DropDownList> </div> </div> Code: <div class="row"> <div class="fieldName">Category</div> <div class="fieldValue"> <asp:UpdatePanel ID="UpdatePanelCategory" runat="server"> <ContentTemplate> <asp:DropDownList ID="CategoryDropDown" runat="server" Width="295px"> </asp:DropDownList> <asp:Label ID="CategoryRequiredLabel" runat="server" Font-Bold="True" ForeColor="Red" Visible="False">required!</asp:Label> </ContentTemplate> <Triggers> <asp:AsyncPostBackTrigger ControlID="discountTypeDropDownList" /> </Triggers> </asp:UpdatePanel> </div> </div> thanks in advance Hi All, Need a bit of help here, need this SELECT to submit the page and end up at the below URL, correctly passing the GET values through the string. <code> <select name="dir-fact-misma" id="dir-fact-misma" class="text100" tabindex="" onChange="alta_nueva.action='alta.php?page=p2#alta'; return true;"> <option value="Si" <?php if(!isset($_POST['dir-fact-misma']) || $_POST['dir-fact-misma'] == 'Si') print "Selected='Selected '"; ?>>Si</option> <option value="No" <?php if(isset($_POST['dir-fact-misma']) && $_POST['dir-fact-misma'] == 'No') print "Selected='Selected '"; ?>>No</option> </select> </code> the form in which this SELECT is placed needs to be submitted so that other fields in the form are not lost, they are saved in Session Variables. the same javascript but activated through an onclick event works perfect elsewhere in the same form with the following code, i think its the onChange that doesn't work for some reason. <code> <input name="p1" type='submit' id="p1" onclick="alta_nueva.action='alta.php?page=p1#alta'; return true;" value='1' /> </code> the page is programmed in PHP. Any help is appreciated. I am trying to add an onchange event to a select tag. This is my code, but it does not appear to be working. Any advice is appreciated. Thanks...

All, first post on the forum. I hope this is relatively simple. I've looked around for the answer, but I thin think the search terms (update onchange event) are a bit too common... Code: document.getElementById("tester").innerHTML= "hello";
document.getElementById("tester").onmouseover = "alert('hello')";
You see I'm trying to change an event like I'd change a property. The first will change the text to hello. I'd like the second to change the onmouseover event to display a hello world alert... but it doesn't seem to do anything. How can I change events? Jason Hello ladies and gentlemen, I would like to use some event handling on a form, not something I have done before and looking for some assistance. Here is my code: Code: <select name="LocO"> <option value=""></option> <option value="O">Outside</option> <option value="I">Inside</option> </select> <select name="LocA"> <option value=""></option> <option value="A">A</option> <option value="B">B</option> <option value="C">C</option> <option value="D">D</option> <option value="E">E</option> <option value="F">F</option> <option value="G">G</option> <option value="H">H</option> <option value="I">I</option> <option value="J">J</option> <option value="K">K</option> </select> <select name="Loc1"> <option value=""></option> <option value="1">1</option> <option value="2">2</option> <option value="3">3</option> <option value="4">4</option> <option value="5">5</option> </select> So what I need to happen, is based on the selection of the first selection box, some of the options of the other selection boxes should not be available. If Outside is selected, everything in LocA should be available, but only up to 4 in Loc1... and if Inside is selected, only up to E should be available in LocA and everything should be available in Loc1. Is this possible? |
