JavaScript - Get Parent String Variable In Child Window
Hey, I'm looking for a way to get a variable from a parent window in a child window. I'm aware that you can write the variable to a hidden field and then get the field's value in the child window, but I'm looking for a cleaner (all JS preferable) way of doing this.
Something like this, but I believe this is an out-dated solution: Code: var str = window.opener.str; alert(str); Any solutions? Similar Tutorialsi 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> 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 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.

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>")
Hi, I have parent page with 10 child window and i want to close all child window when click on close session button on parent but first i need to check whether any child window open or not after that action should be done for close the child window. Hi, I am creating a new child air window called "test.html" as follow. How can I call a javascript function in parent window from child window? function createMyWindow() { var options = new air.NativeWindowInitOptions(); options.type = air.NativeWindowType.LIGHTWEIGHT; options.systemChrome = air.NativeWindowSystemChrome.NONE; options.transparent = true; mywindow = air.HTMLLoader.createRootWindow(false, options, false); mywindow.load(new air.URLRequest("test.html")); .... } Thanks, ASM For a parent window opened a child window, how can the parnet window be notified when the child window is closed or terminated? Thank you. 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 Dear Madam/Sir, I would greatly appreciate any help. I am working on this site: http://www.pathology.ubc.ca/Path_UBC...Professor.html. The list of names on the right hand side is conencted to the iframe, left hand side. By clicking on individual name the eprofile is populated in the iframe. Everything works fine but what I would like to add is some kind of extention to the url so we can externaly link directly to each these profiles. Please let me know if this is something that can be done? Many thanks, Debbie Hi, I'm kinda hoping this is possible but haven't found any reference to it... I have a parent page that opens a popup on click that launches a sidebar navigation on the right of the screen and resizes the parent page. What I am wanting to do is create a second popup (approx 250px high) that opens below the navigation (which is only around 600px high) but I have noticed that even when you have no status bar in the popup windows, they can still end up overlapping because of additional tools or plugins that the viewer has in their browser. Is there any way to get the popups to butt up against each other instead of overlapping? More like a relative popup? Any assistance would be appreciated. :-) After open a child window, I would like to keep parent window on focus. I tried self.focus(), set new window in blur() as well as setting the setInterval, none of them works in either Firefox or IE. I think this question relates to the opening window in tab rather than in new window. Actually, in Firefox, it was opened in tab and in IE it was opened in new window. After a parent checkbox has been selected and the user changes their mind and just unchecks the Parent checkbox I need to figure out how to automatically uncheck the child checkboxes as well. Code: <script type="text/javascript">
function toggleMe(a){
var e=document.getElementById(a);
if(!e)return true;
if(e.style.display=="none"){
e.style.display="block"
} else {
e.style.display="none"
}
return true;
}
</script>
<script type="text/javascript">
$('input[type=checkbox]').change(function() {
// get id of the current clicked element
var id = $(this).attr('id');
// find elements with classname 'parent-<id>' and (un)check them
var children = $('.parent-' + id).attr('checked', $(this).attr('checked'));
});
</script>

I am trying to pop up a window and then do stuff(set flags) when the content of the new window is done loading. For this I am trying to detect the window.onload of the pop-up child window but so far I am unsuccessful. I believe my problem is that the URL of child window is on different domain, than the one of the opener(parent) so that the window.onload is not being called. Thought this may change, at the moment I do not have access to the code for the page I'm opening up in the pop-up. Im pretty new to web development. Any help is appreciated. Heres my js code Code: //globals
var popupHandle = null;
var openingWindow = false;
function popWindow(URL){
var windowId="sameid";
if (openingWindow == true)
{
alert("Please wait, content is still loading")
return;
}
if ((popupHandle == null || popupHandle.closed)){ //is first time run or window was closed
openingWindow = true;
popupHandle = window.open(URL, '" + windowId + "', 'toolbar=0,scrollbars=0,location=0,statusbar=0,menubar=0,resizable=0,width=900,height=500');
popupHandle.onload = function(){
//this is the code that never executes even if I all I put in here is simple alerting
openingWindow = false;
windowHandle.focus();
};
}
else{// window still exists, reset attributes
if (popupHandle != null)
{
popupHandle.location.href = URL;
popupHandle.focus();
}
}
}
Note: The whole reason why I am doing this is because if its the first time I am clicking on the button that will open this pop up window and I click it repeatedly very quickly, a new pop up is opened for each time I clicked eventhough the window.open is supposed to reuse the window if it has the same windowId. The first call to window.open takes long enough to not have a window handle ready and this allows other clicks to get through. Hi, I have a small problem with a page I'm working on. I have an anchor tag inside a table that has a mouseover event that updates a contextual help box. I need to add a similar mouseover event to the anchor tag that does the same thing, but updates the help box with different text. The problem I have is that when the mouse is over the table, no matter if I move the mouse over the anchor, the help text only displays the message that is passed from the table's mouseover function call. I think the solution *may* be something to do with event bubbling, but I'm not exactly sure how to implement it. The code I'm dealing with is below: The code below is PHP. The table mouseover (for reference): Code: echo "<table class='cleanTable' width='100%' style='margin-top: 5px'";
echo " onMouseOver=\"updateHelpText('Message 1.');\" onMouseOut='clearHelpText();'>";
echo "<tr><th> </th><th> </th><th>First Name</th><th>Surname</th><th>Last Login</th></tr>";
The anchor mouseover: Code: echo "<tr class='cleanrow'><td><a href='newMember.php'><img border='0' src='images/icon_add.gif'></a></td><td></td>";
echo "<td colspan='3'><a class='workbenchLink' href='newMember.php' onMouseOver=\"updateHelpText('Message 2');\" onMouseOut='clearHelpText();'>Invite a new colleague...</a></td></tr>";
echo "</table>";
The function (javascript): Code: function updateHelpText(newText) {
document.getElementById("helpBox").innerHTML = "<h4> " + newText + "</h4>";
}
Any help with this would be great, thanks.
