Jul 19, 2011I'm new to javascript and html5.
I've been having problems with some simple(?) lines of code...
What I'm trying to do is to simply turn the canvas black and show a small gif on it. Upon executing initCnv(), the canvas turns black as it should, while the sprite image doesn't show up at all. I can't figure out what's going on, I scoured the code for syntax errors, even tried other image formats but to no avail. Image paths are also correct.
Js Doesn't Work When New Content Loaded Into Div / Resolve It?
Sep 27, 2010I'm trying to create a new portfolio website and I've setup the framework the way I'd like to have it. I have some slight animation through the use of jquery, but because I want to preserver that animation availability (on click) I'm needing to do the amateur thing and swap content out in a div - similar to if I were to use an iframe *shudders*.
When you come into the site, you click on a link, and the nav moves up, and the content window opens, displaying the content for the link selected. When you click on the other links, the content simply changes. This all works as of current. The problem is though, once that new content is loaded into the main content display div, the assigned js and/ or jquery does not work.
The page is live, and can be seen here if you click on the 'about' link, it shows the about page, but has all of the information expanded. If you look at the about page directly,[url] it has some light js that allows the headings of the resume to expand and contract - BUT it doesn't work when loaded into the content window. [code]...

View 3 Replies View RelatedHow Does The Break Statement Work?
Mar 20, 2007For the first time, I'm attempting to write a small Javascript program
using one on the online reference sites. I need some confirmation as
to the behaviour of the break statement.
In the following code:
for ( row = 0 ; row <= 7 ; row++ ) A <----
{
for ( col = 0 ; col <=7 ; col++ ) B <----
{
if ( check ( row, col ) == "pass" )
break ;
}
}
}
Where will control pass to once the break statement is executed?
Will it continue with the first 'for' statement (A) or the second (B)?
Also my 'check' function needs to pass an indication as to it's
success or failure. It does it by:
return ( "pass" ) ;
Am I doing it correctly?
Any links to useful reference sites would be welcomed.

Switch Create a HTML that uses Javascript. Create a page that tells a student the range their mark falls in if they know their letter grade. Below 50 is an "F", 50-59.9 is a D, 60 - 69.9 is a "C", 70 - 79.9 is a "B", 80 - 89.9 is an "A" and 90 - 100 is an "A+". You determine the input and output format.

Variable Doesn't Work In An Object Statement
Feb 19, 2010I have an input form that accepts numbers. I am trying to compare the last field value to the current field value. My problem is that when I use the variable name of the last field in an object path, I get the error "null or not an object". The var 'L' is the problem in the statement below. If I manually type the field name in place of 'L', it works fine. How do I have to write this statement so 'L' works?
Problem statement:
c=window.document.save_info.L.value;
Here is my code: Form element:
Code:
<input style="border:1px solid gray; background-color: #FF9;" onkeyup="moveOnTwo('frm_score1',<?PHP echo $num_holes; ?>,this,'frm_score2')" size="1" maxlength="3" name="frm_adjsc1" id="frm_adjsc1" />

function moveOnTwo(lastFieldID,holes,field,nextFieldID){
var L = lastFieldID ; var N = nextFieldID;

OnClick Works Properly But Following If Statement Doesn't Work?
Sep 1, 2011I have a simple problem that I can't solve. I am trying to code a "More Info" button/link to display some more technical details of an item, if required or wanted. I haven't tried incorporating any code in to my web site yet, first I am trying to test how it can be done in a seperate file.
What I have right now is a table with two cells. In one cell is static text, in the other is a hyperlink. The onClick event calls a JS function called "more_info()" in which a global varible is altered to contain the value 1.
Directly after these two cells is more JS (this is before the table ends). The JS here is checking to see whether the value of the global variable has been changed. If the value is 1, display information. There is no "else" clause because I don't want information displayed unless the variable is equal to 1, so it is not required.
I think I know what the problem might be. The browser is reading the code in question before I ever click the link and has already been executed before the variable is changed. I know JS is object oriented so it will not sit there waiting for me to click the button before reading the logical statements.

Ajax :: Script Update Doesn't Work Without Alert() Statement?
Nov 19, 2010I have a JavaServer demo I'm working on with a bit of JavaScript and thought I'd try adding some AJAX. Its a forum, and the idea is that a post window is revealed when the reply message is clicked. This button is in a jsp page has an onclick attribute to the showEditor() function below. A cancel button is similarly hooked up to hideEditor(), and the submit button calls copy() with a onsubmit tag. A servlet sends a response which has both the HTML for the post area (its a rich-text editor in an iframe, with a bunch of buttons above it much this one) and a Javascript object called Editor that has handlers for all the buttons and sets up the iframe so it is editable.
I actually got it to work okay, until I removed the last alert() I was using for debugging. Then the iframe stops being editable, and the editor.appendQuote() function either doesn't work or doesn't run.
This isn't terribly important because all AJAX accomplishes here is not sending all the post-related HTML and Javascript unless it is actually needed, which isn't all that much, but it would be nice to figure it out anyway.
Code:
<script type="text/javascript">
var editor = null;
function showEditor(node) {
if (node != null) {

Alert() Statement Lets Code Work, Remove It, Code Errors Out
Dec 17, 2007I am a novice, almost to an intermediate-level JavaScript guy, so much of this is new to me. I appreciate your patience reading this.
I have a routine that creates some HTML on the fly (updateFilters() function) and after the HTML is created, I attempt to access some fields (elements) on the form itself.
I works fine if I place an alert() statement after the HTML is created, but when I remove, the code errors out.
I have tried the setTimeout() statement, but I cannot grab the element --- undefined or null is returned. It seems that the form is the only element I can get a handle on --- everything else is undefined or null...
Here is the code:
function editQuery() {
var f;
var x;
var myForm = document.forms[0];
// Get the row filters that were used in the last query..
for (f = 1; f < 16; f++) {
var filter = eval("myForm.FilterList_" + f);
if (filter.selectedIndex > 0) {
var methodElement = element("FilterMethod_" + f);
var methodIndex = methodElement.selectedIndex;
var savedFilterMethodValue = methodElement.options[methodIndex].text;
var choicesElement = element("FilterChoices_" + f);
var choicesIndex = choicesElement.selectedIndex;
if (isNaN(choicesIndex)) {
var savedFitlerValues = choicesElement.value;
}
else {
var savedFitlerValues = choicesElement.options[choicesIndex].text;
}
updateFilters(filter); // update the filters
// take the saved methods and values and then update the selections
// Alert here makes the code work..
// alert("Try this");
// Wait for HTML..
setTimeout("completeEdit()", 1000);
function completeEdit() {
// Since the object was updated, get the object again..
var methodElement = element("FilterMethod_" + f);
for (x = 0; x < methodElement.options.length; x++) {
if (methodElement.options[x].text == savedFilterMethodValue) {
methodElement.options[x].selected = true;
break;
}
else {
methodElement.options[x].selected = false;
}
}
// Since the object was updated, get the object again..
var choicesElement = element("FilterChoices_" + f);
for (x = 0; x < choicesElement.options.length; x++) {
if (choicesElement.options[x].text == savedFitlerValues) {
choicesElement.options[x].selected = true;
break;
}
else {
choicesElement.options[x].selected = false;
}
}
// Only display next row if f = 2..
// If only one row was used, no reason display the next row..
if (f == 2) {
displayNextFilter(f - 1); // display it
}
}
clearTimeout(timeOut);
}
}
}
Do I have to pass the object (the form, the elements) to the completeEdit() function in the setTimeout() statement?

JS Works In IE9 But Not In IE8 - Chrome / Resolve This?
Aug 24, 2011I am trying to do a setInterval to switch the background-image of a div. The switch will happen every second.

Can't Clear Textfield / Resolve This?
Jul 19, 2011I am fairly new to javascript and am having trouble clearing a text field. I am making a "vending machine simulator" as an exercise. I have a button that is the coin return, and should clear the balance display. e.g the machine shows a balance of $2 inserted, the coin return button should clear it to 0.
I believe I have done everything correctly but get NaN as the output (a text field named "box1"). I believe it has something to do with how the field is validated. It has number precision set to 2, which I would think would just become 0.00 or something. Anyways, here is my code code...
Can't Change CSS Value In Script / Resolve This?
Mar 9, 2010I am really confused. I want to make a <p> tag hidden using javascript, and then, if i detect its running IE, i want to make it visible. I can't even make it hidden though. I have tried code... and I've tried both of these variations with the getElementById('warning') instead of plain old document.warning too. Nothing works. I've even tried setting display to none. What is going on?
