JavaScript - Problem With Mouseover Events For Child/parent Element
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.

What it's saying isn't actually true (I don't think)... this is how the section is laid out: Code: <div id="submenu1" class="anylinkcss"> <ul> <li class="contact-pm"><a href="/index.php?do=pm&act=new&to=$RateViewProfileUserName$&returnurl=$ReturnURL$">PM me</a></li> <li class="contact-email"><a href="/index.php?do=email&id=$RateViewProfileUserId$">E-mail me</a></li> <li class="contact-msn" id="msn1">$RateViewProfileUser-profile_msn$</li> <li class="contact-yahoo" id="yahoo1">$RateViewProfileUser-profile_yahoo$</li> <li class="contact-skype" id="skype1">$RateViewProfileUser-profile_skype$</li> <li class="contact-facebook" id="facebook1"><a href="$RateViewProfileUser-profile_facebook$"><span id="fbook-add"></span></a></li> </ul> </div> <script type="text/javascript" src="/html_1/js/contact-information.js"></script> Does anyone know why this might error in just IE? Hi Experts, i have 2 JS array and i need to have dependency between them knowing that 1st Array has parent element of the 2nd one. i.e ARRAY1 ID VAL ID2 2 Dep1 10 3 Dep2 20 4 Dep3 30 ARRAY2 ID VAL ID2 PARENT 20 team1 11 10 21 team2 12 10 22 team3 13 20 23 team4 14 30 i need to have two different DDL's where when i choose VAL = Dep1 on ARRAY1 , i should see on the 2nd DDL only elements with parent corrsponding to Dep1 ( PARENT =10). how this can be possible thanks My application reads an array of URLs in Javascript and displays them in a table. I need to create mouseover events for each of the links (just an alert message for now.) I have tried this a few ways, but for each one the mouseover event fires for each link before anything else is loaded on the page, and when the page is loaded, no link is displayed. Here are the two ways I've tried: Code:
var cell1 = document.createElement("TD");
cell1.innerHTML = '<A HREF= ' + url + 'onMouseOver="' + alert("my alert box"); + '"> my page </A>';
Code: cell1.innerHTML = '<A HREF= "' + url + '"> my page </A>';
cell1.onMouseOver = alert('alert');
I have also tried many variations of these including: Code: cell1.innerHTML = '<A HREF= "' + url + '"> my page </A>';
cell1.onMouseOver = function(){alert('alert');};
Code:
var cell1 = document.createElement("TD");
cell1.innerHTML = '<A HREF= " ' + url + ' " onMouseOver=" alert("my alert box"); "> my page </A>';
But they all yield the same result, so any help would be much appreciated! 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 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">

if(!e)return true;

e.style.display="none"
}
return true;
}

$('input[type=checkbox]').change(function() {
// get id of the current clicked element

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? I have home page with session close button and 10 child window link and i am opening all child window.All child windows should close after clicking on session close button. Code bellow <html> <script type="text/javascript"> openWins = []; curWin = 0; function openWin(page) { openWins[curWin++] = window.open(page,'_blank'); } function closeAll() { for(var i=0; i<openWins.length; i++) if (openWins[i] && !openWins[i].closed) openWins[i].close(); } window.onunload = closeAll; </script> <body > <input type="button" onClick="openWin('http://www.google.com');" value="Open PopUps"> <input type="button" onClick="closeAll('http://www.google.com');" value="Close PopUps"> </body> </html> I have three images nested in three divs that I want to change size on mouseover, but since they're each in their own div, I can't effect their z-indexes relative to one another without targeting their parent divs. I thought I'd be able to contain the images in an <a> tag with z-index style in a mouseover, but I can get it to work. What am I doing wrong here? CSS: Code: .thumb img{
height: 75px;
}
.thumb img:hover{
height: 150px;
}
JS: Code: function thmbOver(){
this.style.zIndex = "1000";
}
HTML: Code: <div id="div1"><a onmouseover='thmbOver();'><span class='thumb'><img src='thmbs/image1.jpg'></span></a></div> <div id="div2"><a onmouseover='thmbOver();'><span class='thumb'><img src='thmbs/image2.jpg'></span></a></div> <div id="div3"><a onmouseover='thmbOver();'><span class='thumb'><img src='thmbs/image3.jpg'></span></a></div> I've tried a few approaches to the function's targeting, like document.getElementById(this.parent.id).style.zIndex, etc, but still nothing. Any ideas? Thanks, ~gyz I was wondering if there was any way I can give a child element, preferably the first one, a link through a parent element with an ID. An example: Code: <div id="parent"> <a href="/">Name</a> <-! start message -> <b>child element text</b> <-! end message -> </div> I want the bold tag to have the link, basically. But through javascript. Hello; I have a situation where an image tag is nested in an anchor tag set. The anchor is assigned an id and is assigned a click/onclick event listener. The anchor id corresponds to a list of objects in an array. In practice, the image tag is receiving the event. The code does setAttribute in another elements img tag src attribute. The image tag receiving the click event, (and passing it to the anchor tag) is event.target. (or event.srcElement, in the case of I.E.) My Question: What I want to know is how to reference the event.target parent element, the anchor tag elements Id attribute. Code: sample anchor/img tag set: <a style="font-family:Arial, Helvetica, sans-serif;color:#cccccc" id="An 1" alt="An 1" href="javascript:"><img style="border:1px solid;border-color:#cccccc" src="WC_port/windows/img//an_1.jpg" width="100" height="131" /><br /><br />An 1</a> I see the double slash in the img src path attribute. It is working as is in test browser: Firefox ( so far) This is in development stages. Later, I will assign the elements a css class rule. in my code, event.target.src has a usable value (src attribute of the img tag) It does not have a usable value for event.target.id (id attribute of the anchor tag) I am doing it this way so in the absence of javascript, the anchors href attribute defaults to a non scripted value. Thank you for time and attention JK ok so here is the problem in more detail i have a dropdown menu wrapped in a div attached to this div is the onmouseout event which hides the div this is working the problem however is when moving from 1 link to the next in the dropdown the onmouseout event of the wrapper div is firing and hiding the div prematurely see it live relevant code: Code: <div id="roster_drop" class="drop_menu" style="left: 128px;" onmouseout="this.style.display = 'none';"> <a href="roster.php">Superstars</a> <a href="champions.php">Champions</a> <a href="titlehistory.php">Title History</a> </div> how do i make the event only trigger when your mouse leaves the div itself and not crossing onto a link Hello, I have this short script he Code: function resizeImages() { //Function will be ran onload in the <body> tag
var img = document.images; //Puts all the images in an array
for (var i = 0; i < img.length; i++) { //A loop to execute a set of functions for every image
var parentElement = img[i].parentNode; //Gets parent element of image
var parentWidth = parentElement.width(); //Gets width of parent element (value is an integer without "px")
var imgWidth = img[i].width(); //Gets image width
var parentHeight = parentElement.height(); //Gets height of parent element
var imgHeight = img[i].height();//Gets image height
if (parentWidth < imgWidth){
img[i].width(parentWidth); //Sets width of image to width of parent element
img[i].style.height = "auto"; //Scales height
}
if (parentHeight > imgHeight){
img[i].height(parentHeight); //Sets height of image to height of parent element
img[i].style.width = "auto"; //Scales width
}
alert(parentWidth); //To test if parentNode is working correctly. Should return an integer.
}
}
It's got some JQuery in it (.width() and .height()) to make manipulation of the dimensions easier to manage. Basically, it's supposed to resize all the images on the webpage to the size of their parent elements (divs) without losing aspect ratio. Image overflow will be hidden so that no matter what the aspect ratio of the image and it's container the largest possible area of the image will be exposed. The alert() function I have at the bottom is supposed to run as a test that each loop is working correctly. However, my images don't get resized and I get no alert. I think the loop may be breaking out before it goes through everything. Anyone have ideas? I'm not a Javascript coder. Thank you, Jared For a widget I made, I have a dropdown select menu. It is constrained to a very small width and IE does not auto expand on click. I wrote a simple javascript to handle this but I run into two problems. The onmouseout function is fired when I click into a child node, and the onmousedown of the <option> tags doesn't work in IE. The code works fine in all other browsers. var wid; var campaign_i = 0; function campaignWidget_capture(myID){ wid=document.getElementById(myID).style.width; campaign_i++; } function campaignWidget_SubDes(myID,state){ if(state==0){ if(campaign_i==0) campaignWidget_capture(myID); document.getElementById(myID).style.width="auto"; }else document.getElementById(myID).style.width=wid; } onmouseout="campaignWidget_SubDes(id,1)" This is in the select tag. onmousedown="campaignWidget_SubDes(id,0)" This is in the select tag onmousedown="campaignWidget_SubDes('campaignWidget_Sub_Designation',1)" This is in the option tag. I want to implement a javascript function where a submit button will be submitted from the parent page each time I close a child page. Please let me know what I did wrong in my code and please elaborate your answer so that I could understand it better. Thank you so much for your help. I have the following jscript code but it is now working. Code: window.onunload = submitParent;
function submitParent()
{
var doc = window.opener.document,
theForm = doc.getElementById("finalForm");
theField = doc.getElementById("finalSelected");
theForm.submit();
theField.trigger('click');
}
My form from the parent page is as follow. I want my jscript to just click on the submit button once. Code: <form id = "finalForm "name= "finalForm" method="POST" action=""> <input type="Submit" id = "finalSelected" name="finalSelected"/> 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 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. 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 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>")
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. |
