JavaScript - Issue With Offsets And Display Property
Javascript:

if (document.getElementById(menuName).isActive == "1")
{
var listItemHeight = document.getElementById(listItem).offsetHeight;

document.getElementById(menuName).style.display = "block";
document.getElementById(menuName).style.opacity = "1.0";

HTML: Code: <div id='db-sub' class='ddm-db' onmouseover="showMenu('db-sub');" onmouseout="hideThis('db-sub');">

The remaining HTML for the the 'dqb-sub' element that is displayed follows an identical format to 'db-sub'. Mousing over the upper elements produces a drop-down menu that is aligned with the position of the top-most element in question. Mousing over the 'dbq' element produces the element 'dbq-sub' at the (0,0) position of the window, which is my issue. I believe it has to do with the fact that I'm setting the display property to 'none', which essentially destroys the element, along with its properties. What doesn't make sense is that while the 'db-sub' element is set to a block display type, it should have valid, non-zero offsets. I'd like the 'dbq-sub' element to position based on where the 'dbq' element is. Any ideas? Similar TutorialsI have a page: http://www.girlscoutsmoheartland.org...progsearch.php that works perfectly fine in every browser I try, except for actual IE7 (it even works fine in IE8 emulating IE7). When you search for something on that page and have a display of results, each result has a link that changes a table row's display to visible, and hides the row when clicked again. It doesn't do that in IE7. There are no errors or warning in Firefox's Error Console. But IE7 has an "Error on Page" notice (which does NOT appear in IE8 emulating IE7), that says: Line: 59 Char: 11 Error: Could not get the display property. Invalid argument. The script in question is this, with what would be line 59 indicated: Code: <script type="text/javascript">
<!--
function toggle_visibility(id) {
var e = document.getElementById(id);
var f = document.getElementById(id + "b");
if(e.style.display == 'table-row')
e.style.display = 'none';
else
e.style.display = 'table-row'; <<-- This is line 59
if(f.style.display == 'table-row')
f.style.display = 'none';
else
f.style.display = 'table-row';
}
//-->
</script>
I really don't know what to do, or where to begin. Everything in my limited knowledge seems to be working just fine. Most of my site's visitors use IE8, but enough use actual IE7 that I really need to fix this. Thanks for any help or advice! Liam I wrote a script that creates 2 absolutely positioned divs, in perfect alignment, one on top of the other. I want to use javascript to manipulate the display property of each div to show one div at a time by toggling each div's display property between none and block with an onClick event handler attached to the link. This script works fine when the javascript function has no parameters, because the div id's are inserted directly into the getElementById function. When I say it works, I mean the div with id=cal2 displays onload, then disappears when the Show Calendar link is clicked. The div that appears in its place has a link that does the reverse when clicked. I want to create multiple pairs of overlapping divs that toggle their visibility, so I want to put parameters inside the functions that identify the specific pair of divs that need to be toggled per function call. When I try to use variables/parameters in the functions to insert specific div id's into getElementById, it does not work. PLEASE NOTE, the code below has div id's in green that don't have quotes of any kind. It still works in my firefox browser. I thought id's needed quotes, but it works without. I don't know why. The code below works, but has no parameters in the functions: Code: <!DOCTYPE html>

Thanks for reading all of this. Does anyone know what I'm missing? I won't even pretend to know what I'm doing. I'm just trying to update a few things on our company's website. We implemented live chat and some new graphics to accomodate our banner. We use two main index files (one sorts by category and the other by manufacturer). Originally these two files along with every single product page referenced the banner code from a javascript file named: header.js This is fine in firefox but IE isn't too thrilled with it and does something fairly strange (at least to me). Here's a link to the problem (open in IE): http://www.alamomotorsports.com/act/act.html Here is the Java code Code: <div id="header_container">
<div id="header">
<div id="header_lh_cell"><a href="http://www.alamomotorsports.com"><img src="http://www.alamomotorsports.com/images/AMSTopper.jpg" alt="Jump to the Alamo Motorsports Homepage" /></a></div>

Thank you for help in advance. Hello all, I'm trying to set up a web page to display a video when a user clicks on a link. So far, it works fine in IE and Chrome, but it won't work in Firefox. Any ideas? http://tinyurl.com/6u3jnq5 I have this simple manual photo slide show. It shows four photos and when you click the next button and it moves one photo over and one photo back for the previous button. I have to moving by changing the CSS property of 'left' by 195 pixels each move. So for it to move next it will subtract 195 pixels from the left property and for moving back it add 195 pixels to the left property. I have the code setup so when you click it changes the property of left to either -195 or 195 pixels but I need it so it actually does the math, not just give it a set value. But I don't know how to do that. Code: function MM_changeProp(objId,x,theProp,theValue) { //v9.0
var obj = null; with (document){ if (getElementById)
obj = getElementById(objId); }
if (obj){
if (theValue == true || theValue == false)
eval("obj.style."+theProp+"="+theValue);
else eval("obj.style."+theProp+"='"+theValue+"'");
}
}
function nextPhoto() {
MM_changeProp('fanThumbWrapOne','','left','-195px','DIV')
}
function prevPhoto() {
MM_changeProp('fanThumbWrapOne','','left','195px','DIV')
}
so where you see -195px and 195px in the functions for nextPhoto and prevPhoto I need those to actually be functions where it subtracts 195px or adds 195px. When I click on the image I want to get the "margin-left" value of its block. In the code below the margin-left is set at 100px. But when I click on the image the "margin-left" value shows in the "alert" as undefined. What code changes do I need to get the correct margin-left value? (Please, no guessing!) [CODE] <script type="text/javascript" > window.onload = function(){ document.getElementById("holder").onclick = showit; } function showit( ) { var marval = document.getElementById("holder").style.marginLeft; alert(" margin-left= " + marval + " typeof= " + typeof marval); } </script> <style type="text/css"> #holder{ padding: 0px; margin-left: 100px; } </style> </head> <body> <img id="holder" src="anyimage.gif" width="300px" height="200px" /> </body> [CODE] I had read from books that the constructor property of object is inherited from its prototype. And the prototype can be changed dynamically. New property can be added to or deleted from object even it was created before the prototype change. But I got confused on below codes. Code: function A()
{
this.title = "A";
}
function B()
{
this.title = "B";
}
document.write("<br>");
var b = new B();
document.write(b.constructor);
document.write("<br>");
document.write(B.prototype.constructor);
document.write("<br>");
B.prototype = new A();
document.write(b.constructor); // Suppose to output "function A() ..."
document.write("<br>");
document.write(B.prototype.constructor);
document.write("<br>");
B.prototype.constructor = B;
document.write(b.constructor);
document.write("<br>");
document.write(B.prototype.constructor);
document.write("<br>");
But the actual result (both IE and firefox) is Code: function B() { this.title = "B"; }
function B() { this.title = "B"; }
function B() { this.title = "B"; }
function A() { this.title = "A"; }
function B() { this.title = "B"; }
function B() { this.title = "B"; }
Please help me. thanks. Hi, This is my first post while learning Javascript and jQuery as total noob. I have something like this: Code: var desc = "This is your title and here is even more that might be added so that we can get at least 60 characters or so";
var desc = desc.trim().substring(0, 40).split(" ").slice(0, -1).join(" ") + "...more";
alert(shortText );
It is actually being used on a page that calls a description from a MySQL table, but this example fails in exactly the same manner. Although FF and other browsers successfully initiate the script with errors, but IE loops endlessly and freezes up. FireBug reports "reference to undefined property a[d]". Using jQuery 1.6.2. I'm not really sure what property is undefined here and how this can work without freezing IE. Thanks in advance for any help! AJ I am sorry the following code is a bit of a mouthful, but I can't find a better way to display the problem. The code works as expected in Chrome, but not in IE and FF. In IE the error is "Object doesn't support this action" and in FF "setting a property that has only a getter". In Chrome there is no error in the console. There are three javascript <script>...</script>s that exist to display a <td> row in a table with a particular graphic depending on the screen width. The odd thing is that in both IE and FF (and of course Chrome), the first two scripts display perfectly well. Why does the third <script> produce an error? It has exactly the same form as the two before it. I can only guess it has something to do with where it occurs Googling the FF error, it has something to do with trying to set a read-only property, but then why do the first two <scripts> work? They are no different (at least I can't see a difference.) Code: <table border="0" width="100%" cellpadding="0" style="border-collapse: collapse" id="table3768">
<script>

Any light on this would be most welcome! 1. When creating a new element using the create method, do the zIndex values of all elements that follow it change? If so how do I get the zIndex of all divs with a specific classname within a specified container? I'm working with dynamic drive's 'dhtmlwindow' object class file and have made revisions to it...however this is my first time working with this type of file and while some things are easy to change the zIndex change of the setfocus function does not look like any of my previous scripts. Hello, I have the following object: Code:
var layers = {
photo1 : {
index : 1,
xPos : 63,
yPos : 48,
angle : 0
},
background : {
index : 0,
xPos : 278,
yPos : 163,
angle : 0
}
}
How can I sort the objects by the index property? Code: for(var layer in layers.sort(???))
{
}
Thx Very Much! Hi I need to change the font color of the disabled textboxes of our application. These disabled textboxes exist at thousands of places both at pageload or disabled conditionally clientside. I am aware that in IE8 there is no other way to change the fontcolor except use readonly. So i thought that maybe if I changed the .disabled property to something like - Code: Object.disabled {
function set() {
this.readOnly = value;
}
function get() {
return this.readOnly;
}
}
then it would make my task much easier. I searched and found out that Object.defineProperty ,may do the trick. However i am getting the mull reference error. Is there any other way? For some reason I run my script and its saying missing } after property list. But I'm not seeing it. Code: <script type="text/javascript">

Any help would be awesome and much appreciated! I'm trying to change an id by referencing the previous site the user was on. In this case the user will be coming from either facebook or linkedin. I'm not sure if i'm calling the referrer property correctly. Again, any help is greatly appreciated! <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>Untitled Document</title> <script language="JavaScript"> if(document.referrer.toLowerCase().indexOf("facebook") != -1) { document.getElementById("phone").innerHTML = "555.555.5555"; } else if (document.referrer.toLowerCase().indexOf("linkedin") != -1) { document.getElementById("phone").innerHTML = "222.222.2222"; } else { //Default code } </script> </head> <body> <p id="phone">123.456.7890</p> </body> I've got this JavaScript code that is doing stuff to the content of <TR> rows.. but it's overselecting and I need to filter the <TR>s it selects in the bold line. var theRows = document.getElementsByTagName("TR"); var r = 0; var strTitle = ""; while (r < theRows.length) { try { strTitle = theRows[r].innerText || theRows[r].textContent; strTitle = strTitle.replace(/\n|\r|\t|\^ /g,""); if (strTitle.substring(0,1) == "(") { if (strTitle.indexOf("STAT") == -1) { theRows[r].style.display = "none"; ... continues Below is the rendered html. What I really want to do instead of if (strTitle.substring(0,1) == "(") Is only perform the operation when a row that is using class="ms- formlabel, or maybe has a FieldInternalName.

Do you become short of breath or develop chest pain when climbing a flight of stairs?" FieldInternalName="ShortofBreath" FieldType="SPFieldBoolean" --> <span dir="none"> Thanks for any help or information! I'm using ccs3PIE with my site. What I want to do is check if a DOM element has a css property like border-radius and then add a class to it. The problem I'm having is that I don't know how to check for the css property. I've been searching for it for a couple of hours now and I can't find anything that seems to work. Any ideas? I am and seem to remain newbie ... I have a JS script that presents a series of "pages" with different questions inside a single HTML file, by rewriting certain <div>s. I have an object like this that contains the questions and information about answer labels etc (the idea is that this should be easy to modify for someone who doesn't know JS): Code: var Questions = [
{
"question" : "How good is this?",
"labels" : ["excellent","very good","good","bad","very bad","awful"],
"page" : 0 ,
"random" : false ,
"type" : "default",
"varname" : "allgood"
},
{
"question" : Change[curCase]+"What do you think now?",
"labels" : BetterLabels,
"page" : 1 ,
"random" : true ,
"type" : "default",
"varname" : "betteradapt"
}
]
This object is initialized when the page loads, and a function reads the total number of pages by getting the maximum number of the "page" property across elements. Later, the object is accessed by thenextQuestion() function which uses the "page" property to looks whether each element belongs on the current page , then reads out the properties and presents the question. This works okay. Now the tricky bit: For some questions, their text should be different depending on which case is currently on the screen (Change[curCase]). curCase is different on each page, an integer between 0 and Change.length. I cannot get this to work for the Questions object, probably because the Questions object has been already initialized when the page loaded. How can I get my function nextQuestion() to "re-evaluate" the property "question" for all the elements of the Questions objectwhen nextQuestion() is called , using the current value of "curCase"? nextQuestion() is longer, but the (i think!) crucial bits are he Look whether question belongs on current page and push it onto new array: Code: for (i=0; i < Questions.length; i++) {
Questions[i].page = Questions[i].page;
if ( Questions[i].page == BlockNum ) { // if the q belongs on the current page
QuestionsObjectThisPage.push(Questions[i]);
}
}
Then, extract an array containing the questions, which will then be presented: Code: for (i=0; i < QuestionsObjectThisPage.length; i++) {
QuestionsThisPage.push(QuestionsObjectThisPage[i].question) ;
}
So what I'm looking for is something to change either of these two Object.push() functions so they don't simply take the value they find in the Questions (or QuestionsThisPage) object, but to re-evaluate the code for the "questions" property, taking into account the current value of curCase Phew. I found that really hard to describe; hope it's somewhat clear. Hello, how can I make the following object work properly so when I use 'layers.photo1.layer' a jQuery element is returned rather than the text of the function as it is now. I also need to be able to find the element by the photo1 object its contained in not have to input a string there so that I can also reuse it in the background layer. Code: var layers = {
photo1 : {
layer: function() { return $(element).find($('photo1'))}
},
background : {
layer: function() { return $(element).find($('background'))}
}
}
Thx Very Much! Hello I am new to javascript and have the following question: Is it normal that the Document.links property only counts links that are placed before the command? example: Code: <body> <script type="text/javascript"> document.write (document.links.length); </script> <p><a href="http://www.youtube.com/watch?v=gt9j80Jkc_A#">Youtube link</a></p> <script type="text/javascript"> document.write (document.links.length); </script> </body> The result is Quote: 0 Youtube link 1 How can I avoid this? Only by putting the code at the end of the document? And since i am asking? Is it possible to search a entire document for a string and replace that string with one command? (don't give me exact solution please just a hint what direction i should be searching in). Kind regards I'm new to JavaScript, just started an adult education class in it. I wrote a simple script to view a list of document properties and their values. This part works in Internet Explorer: for (var prop in document){ p_prop = prop; p_list[i] = p_prop + " : " + document[prop] + "<br />"; but doesn't in FireFox. I was wondering how to get the value of a property in FireFox. Thanks. |
