Which does not work, what I am trying to acomplish is set the class of an object, if I do the whole thing inside a function it all works, however if I create another function that calls a second function it does not, how could I use the object that fired the event in the numbers() function?
I am working a project for school in which I am trying to make a simple math game. When the user clicks the start button it will bring display a question and ask for an answer. What I want to to is when the user clicks the start button it will swap the button for to other buttons to move to the next question and one to restart the game. Which works fine, the problem is after the buttons are swapped.
How would I access a sub function from a buttons onclick event? I currently have onclick="return MathGame.resetForm();" but that throws an exception and I can't see where. What is the best way to go about this. Also this is my first attempt at using javascript in this manner so I'm probably going about it the wrong way.[code]...
I'm wanting a table cell click event to remove and replace the table it was clicked on, however I'm finding that as it's deleting the original table object the actual running event code is being replaced and the function is bailing.how I can call the delete/refresh function from outside the event's function scope?

The above is a simplified example of the problem I'm facing. I could merge functions into one big self-referencing function (i.e. recursive function), but that's ugly and causes other problems (such as when insert form elements and wanting to harvest the user input afterwards). I considered declaring a variable in the top ".ready" function, and have all child functions stuff their HTML changes in it, but that seems to be a pain to keep track of and removes much of the value of using jQuery in the first place...
Is there a nice solution for this? To, after inserting HTML, somehow update the HTML state referred to by jQuery in the non-local scope(s)?
In one of my functions I got the following lambda function. It works as intended, but I got a tiny problem. I'm trying to access the function-scooped variable "matched" and set it's value to "true". The problem is that it seems like the variable is existing as a local variable inside the lambda function, even if it's not declared inside the lambda function itself. So, the change "matched = true;" does not effect the variable that I declared.
Code:
//... code
var matched = new Boolean(false);
xmlhttp.onreadystatechange=function() {
if(xmlhttp.readyState == 4 && xmlhttp.status == 200) {

how would i build a multidimensional array? would it be: PHP Code:
var rinksAndPriceArray = new Array();
rinksAndPriceArray[0] = new Array();
rinksAndPriceArray[1] = new Array();
i've figured that out so far.
now, i want to be able to access a part of one of the arrays based on a variable that is passed into the function
the variable i'll send in will be the first part of the array ex: rinksAndPriceArray[0][0] and i'll want to return the rinksAndPriceArray[0][1] value.
I have an array with mysql´s data. I have used this array with several text

My question is: How could i use the event onchange to make a function which
update the data of array when i would have change data in a text box.?
I try to add a function to be triggered also within an event (which already has a function). I coded it, unfortunatelly one line of the code should be different for IE and Moz. I try to find a common way without using a browser detector... Any ideea? The red line works for Mozilla, the blue one for IE:
function addFunc(){
var e = document.getElementsByTagName('*');
for(var i=0;i<e.length;i++){
if(e[i].getAttribute('onclick')||e[i].getAttribute('onclick')!=null){// Moz || IE
//var f = new Function(e[i].getAttribute('onclick'));
var f = e[i].getAttribute('onclick');
e[i].onclick=function(){f();otherFunction()}

I would to know If I have some input text with the same classname, can I add an event, for example onclick, for each of them without adding onclick="function();" in every input text in the code?
for example I have:

<input type="text" class="inputbox" name="text2">
<input type="text" class="inputbox" name="text3">

I'm having some difficulty in accessing an 'external' function from my onchange event. It will work when the function is included 'inline,' but it's not working when the function is 'stand alone.'Additionally, when it works, the variable isn't being passed - the alert I use says "[object Event]"
Code:
<head>
function nameTextBox2(selectBoxName)

In the file script.js I got 2 functions:
Code:
function tooltip(){
var m=document.getElementsByTagName("A");
var k=[];
var mover = document.createAttribute("onMouseOver");
mover.nodeValue = "showtooltip()";
for (var i = 0; i<m.length; i++) {
var mover = document.createAttribute("onMouseOver");
mover.nodeValue = "showtooltip()";
m[i].setAttributeNode(mover)
}}
This one is working. It's putting into <a href="#" title="some title" /> an attribute: onMouseOver with value: showtooltip()
And that's my 2nd function.
Code:
function showtooltip() {
document.write(this.getAttribute("title"));
}
When event is run the function isn't working. But when my html looks like this:
Code:
<a href="#" title="some title" onMouseOver="document.write(this.getAttribute("title"))">link</a>
Everything is fine. And javascript console doesn't show any errors.
My 2nd problem is, that onMouseOver doesn't work in chrome (I got dev version). Even function like this:
Code:
showtooltip() {
document.write("......");
}
I want to bind a function to an event without having to put the entire code into the anonymous function that I'm binding to the event. How can I do this?

$(".error").hide();

I'm trying to convert an on load event into a function. I think this should be really simple, but I'm new to Javascript. The following works fine as the page loads
var favorite = GetCookie('DemoName');
if (favorite > Ƈ')
{
window.location.href = 'page2.htm'
}
else
{
alert('You must complete the lesson before proceeding');
}
I have tried to make it into a function by adding function CookieRedirect() {
at the top and a closing
} at the end, and calling it using a form button in the body:
<INPUT TYPE="button" VALUE="Redirect" onClick="CookieRedirect ()">-
but no luck.
I have written some dom code to create a list of divs, each with it's
own id. I want to set the onmouseover and onmouseout events to
highlight the div when the mouse is over it. However I cannot use the
method below because oDiv.id is always set to the last div I create -
so the last div is highlighted regardless of which div I am onmouseover
This must be a common issue, how do I go about fixing it?
I can have a separate function which takes event.srcElement and tracks
back through the parent elments until it finds a div with an id
starting with "entry_" but I was hoping for an easier option.
Is this something to do with closures?
Here's a much simplified example :
for( nIndex=0; nIndex<aEntries.length; nIndex++)
{
oEntry = aEntries[nIndex];
oDiv = document.createElement( "div");
oDiv.id = "entry_" + oEntry.uniquename;
oDiv. {document.getElementById(
oDiv.id).className = "hover";};
oDiv. {document.getElementById(
oDiv.id).className = "";};
oBody.appendChild( oDiv)
}
I am writing a javascript code that parses dom and finds event
handlers attached to mouseover events. Then i will replace the
existing handler say B() with my own function say A(). When the event
happen and control comes to my function A(), after doing required
processing i will call B() as shown below
<a href = "abc.com" mouseover = "B();"link </a>
while parsing i will have (trimmed down version)
var oldHandler = node.onmouseover;
node.
function A()
{
/ * my code */
oldHandler.call(this);
}
This was working fine as long as B() was a global function. I started
getting problems when B was a member function. For eg:
function Alerter(text)
{
this.text=text;
var me=this;
this.invoke=function ()
{
alert(this.text);
}
}
var sayHi = new Alerter('Hello, world!');
The web developer would have code like
<a href = "abc.com" mouseover = "sayHi.invoke()"link </a>
But this time around, my function A() fails since although i have
handler to sayHi.invoke(), it has to be executed in correct context.
Other wise "this.text" is giving me error because when i say
oldHandler.call(this), i am executing the sayHi.invoke() with the html
element being passed as this.
I've been using jQuery for some time now but this is the first time I've run into something odd. Currently I'm developing a Theme for Concrete5.4.0.5, which automatically includes jQuery 1.4.2 - meaning, I can't use any other version of jQuery, that said: here is my problem.
I've got the following HTML (heavily simplified):
<nav id="mainNav">
<ul>
<li>Home</li>
<li>Text
<ul>
<li>Subnav</li>
</ul></li>
<li>Text
<ul><li>Subnav</li>
</ul></li>
</ul></nav>
<section id="contentWrapper">
...
</section>
And the following JS-jQuery Code (original, not simplified):
function hoehenAngleichen(){
if($('#mainNav').height() > $('#contentWrapper').height()){
$('#contentWrapper').height($('#mainNav').height());
}}
$(window).load(hoehenAngleichen);
/* works fine until here */
$('#mainNav li').bind('onmouseover onmouseout', hoehenAngleichen); //will not trigger
I want the "hoehenAngleichen" function to be triggered whenever someone is hovering or leaving a li-Element. But this code seems not to bind the events with the named function properly.
I know in JavaScript you are able to write functions that you can just call at a later time. I'm working on a jQuery UI slider, and I wrote a function for the animation that happens when you start sliding. I would also like this same function to fire for the "change" event, but I can't seem to get it to work.
Here is the shortened code sample:
$(function(){
var posterO = $(".poster-slider")
.slider({
slide: function(event, ui){
//This is the function I would like to reuse at "change", below
poster.css(...);
posterLi.css( ... );
ptCopy.css( ... );
sliderValue = ui.value;
},
//change:,
animate:true
});
//When "#abundant-trees" link is clicked, the slider handle changes, firing the "change" event, but the "slide" function is not called.
$("#poster-switcher a[href=#abundant-trees]").click(function(link){
posterO.slider("value", 100);
link.preventDefault(); //Stop browser from following the link that was clicked on.
})});
I would like to apply the "slide" function to the "change" event without having to duplicate all the code.
I am using a slider and want to add labels to the slide/start event. How can I call function from these events? Something like this:
$(function() {
$("#slider").slider({
value:0,
min: 0,
[Code]....
I am confused about how to do this the right way.I have a change event which grabs the value of the selected optionlist and sets that as a var. But, I would like to add that to the endof my post string when I submit the form, how would I do this?
$('select').change(function() {
$('select option:selected').each(function() {
var my_val = $(this).val();
[code]....
<label id="mylabel" onclick="myOnclickFunction()">My Label</label>
How to get the "myOnclickFunction()" _string_ with jQuery? JavaScript getAttribute("onclick") works fine, but I want to do it through jQuery.
