Check Allowed Dropdown Combination And Filter Options?
Apr 2, 2010Using Javascript / jQuery, I'm trying to produce a series of dropdowns ("<select>") that have their options filtered as the user selects from them.
For example:
DROPDOWNS
Field 1:
- value_1
- value_2
[Code]....
When a option is changed all the current entries are removed and only the allowed combinations added back in.
how to find which combinations are acceptable based on what has already been selected.
Event Listener - Check And Activate Function?
Jun 28, 2010Event Listener. From what I understand it will check all events until a defined event happens, such as rollover of a certain image, and then it activates a function? What I want to do is use this so that when I rollover a element such as below:
<img src="img url" alt="this is a tooltip" tooltip="true" />
I want it to pass the obj to a function which then runs, and then once the mouse of not over that element it will activate another function passing the previous object to this function.
Although an element such as the example below would not activate these functions:
<img src="img url" alt="this is a tooltip"/>
As the tooltip tag does not exist or has the value of false. Also, wouldn't this use a lot of resources as it checks every event which the mouse passes over?

Allowed Var Names In For Use With Forms
May 5, 2004I am trying to adapt a script for use validating a drop-down menu in a form.
The script works fine in my lttle demo. In the head of the page I've got...
Code:
<script type="text/javascript">
function checkList() {
var testForm = document.testForm;
if (testForm.demoSelect[testForm.demoSelect.selectedIndex].value == "") {
alert("Please make a valid selection from the list.");
return false;
}
}
</script>
And then in the body...
HTML Code:
<form action="demo.php" method="post" name="testForm" id="testForm" onSubmit="return checkList();">
<p>
demo select menu
<select name="demoSelect" id="demoSelect">
<option value="" selected>Please Select</option>
<option value="1">Attrib1</option>
<option value="2">Attrib2</option>
<option value="3">Attrib3</option>
</select>
</p>
<p>Submit
<input type="submit" name="Submit" value="Submit">
</p>
</form>
No problem, works fine. The problem is that I am trying to apply this code to a PHP page in osCommerce where the name of the drop-down menu (i.e. demoSelect) is generated dynamically. It is only for use in one particular situation where I know the name of the drop-down menu is generated as id[1] but it wont work when I replace the demoSelect for id[1].
I'm only really beginner with JS but I guess it's because JavaScript identifies id[1] as an array? Is this right and any ideas how I can correctly identify my drop-down to JS?
Split() One Document.frames Not Allowed
Jul 23, 2005I want to split the result from window.frames['data_frame'].document.location;, this in order to find out which page is currently opened in the specific frame. When I do it like this:
var source = window.frames['data_frame'].document.location;
// var source = "W3Schools is great!";
index_source = source.split('/');
IE gives an error that this method or property is not supported by this object. When I check it on the other var it is accepted. Is there anyway I can make this work? I already tried to do it with
document.getElementById().src etc.. but that is not very reliable.
Max Num Chars Allowed In Function Param?
Aug 2, 2010I have a page working perfectly that passes up to 10-12k worth of data into a function via an 'onClick' event. That onClick is one of the <img..>'s attributes, directly. In case later that (dynamic) data gets larger, am I toying with potential problams because of some limit - either a limit in what can be passed into a JS function, or else a limit in the max num of characters allowed in an element's attribute(s)? What do you think is the reasonable amount that I can pass before things start to break? I may need to go up to 50k. 100k maybe, but I doubt that much.

Aug 2, 2009I have a DIV blocked from data entry in IE, Firefox, Safari and Opera. Functionally all is okay -- super plugin! The only problem left is that the cursor does not change to 'not-allowed' on the overlay when I use IE 6,7 or 8. All other browsers render the cursor okay?
Here's the code:
$().ready(function() {
Protect('#divData');
$('#cbProtected').bind('click', function(e, ui) {
if ($(this).is(':checked'))
Protect('#divData');
else
Unprotect('#divData');
});

Get Error When Validating - Element Was Found In A Context Where It Is Not Allowed
Oct 31, 2011I get this error when validating:
The element named above was found in a context where it is not allowed. This could mean that you have incorrectly nested elements -- such as a "style" element in the "body" section instead of inside "head" -- or two elements that overlap (which is not allowed).
One common cause for this error is the use of XHTML syntax in HTML documents. Due to HTML's rules of implicitly closed elements, this error can create cascading effects. For instance, using XHTML's "self-closing" tags for "meta" and "link" in the "head" section of a HTML document may cause the parser to infer the end of the "head" section and the beginning of the "body" section (where "link" and "meta" are not allowed; hence the reported error).

Event Listener

This is my code and for whatever reason that I just don't get (coz I'm a bit confused by all this stuff), clicking cancel when the confirm message appears seems to return true regardless. Code:
Javascript Property Listener
Oct 8, 2005I am writing a Javascript UI component. I have already written a
"disable()" method for it, but I would like to go one step further in
order to make my component as compatible with existing HTML controls as
possible.
With standard HTML controls we can do this:
myTextField.disabled = true;
and as soon as this property is set, I assume there is a property
listener of some kind that is invoked to change the appearance and
value etc of the control.
I want to write my own 'property listener' to do this with my control.
Can I do it in Javascript or is this too "low level", requiring code at
the browser implementation level?
AddEvent Listener Not Working?
Aug 23, 2011I have more than 30 addEvent listeners i need to add to my WebApp. But the Code to dynamically add them is not working, unless change:
AddItemEvtAry[x].addEventListener('click', function (e) {document.getElementById("text" + x).value ++}, false);
to
AddItemEvtAry[x].addEventListener('click', function (e) {document.getElementById("text0").value ++}, false);
but obviously hardcoding all of those DIV IDs would defeat the purpose of the code.
Code in Question:
// Event Listeners for Incrimenting Quantities
var AddItemEvtAry = [40];
for(var x = 0; x < 39; x++)

This is the entry point for doing an autocomplete, but for know, I would just like to ask:
What should we do so that, the text that is typed, appears on that alert box?
How To Create An Event Listener?
Jan 5, 2007How do I add an event listener to a few text boxes that prevents the user from typing anything but digits. I use the numbers entered in the text boxes in calculations afterwards so I don't want the user to enter "one" instead of "1" etc... Also, the range of possible numbers is too big for a drop down menu.
View 6 Replies View RelatedAdd Event Listener - Not Working In IE6
Mar 22, 2007I'm writing a custom script to collect attributes from links and concatenate them to pass as a string to another function. I'm using a readily-available 'addListener' function so the click event doesn't overwrite others on the page. All this seems to be working in all browsers except IE6, and I suspect it may have something to do with event bubbling. Can anyone see my errors and any other ways I could improve the script? Code:
View 4 Replies View RelatedCan't Get Event Listener To Work
Sep 4, 2010I'm trying to use the addEventListener function to set an event listener but I don't understand why it won't work. Before i was using another method to handle events, but I needed more control over which event handlers get run and when.
Code:
<html>
<head>
<script type="text/javascript">
function runMe(){
[Code]....
I'm using Google Chrome, but it won't work in Firefox either. Obviously it won't work in IE, since IE doesn't support that method. The script gives no errors at all. The runMe() function does get executed, I tested this with alerts.
Object Method As Event Listener
Oct 16, 2006I want each instance of an object to be able to listen for input events.
When the event occurs, a method of the object should be called, such
that "this" is in scope and refers to the object instance.
Is this possible? Example:
function MyConstructor(element)
{
//element is some HTML element
this.addListeners(element);
this.foo = "Bar";
return this;
}
MyConstructor.prototype.addListeners = function(element)
{
element.addEventListener("keypress", this.doSomething, true);
}
MyConstructor.prototype.doSomething = function(e)
{
alert(this.foo.length); //Error: this.foo has no properties
alert(this);
//shows the HTML element that triggered the event
}
Is there any way to get "this" to refer to the object in the event listener?

Dynamically Add (OnKeyDown) Event Listener
May 9, 2011I have a form with many, many, many 'input type="text"' elements in it. I'd like to be able to dynamically add an 'onKeyDown' event listener. Here's what I've got, so far (I know it's wrong.)
Code:
function addEventToElement(formName,tagName,typeName,eventName,eventAction) {
thisForm = (typeof formName == 'string') ? document.getElementById(formName) : '' ;
thisTag = (typeof tagName == 'string') ? tagName : '' ;
thisType = (typeof typeName == 'string') ? typeName : '' ;
thisEvent = (typeof eventName == 'string') ? eventName : '' ;
thisAction = (typeof eventAction == 'string') ? eventAction : '' ;
if(thisForm != "") { // If elements are in a form, make sure ONLY those elements are affected
elem = new Array(); elem = thisForm.getElementsByTagName(thisTag); // array of all items of [tag]
alert(elem.length);
if(thisType != "") {
for(j=0;j<elem.length;j++) {
if(elem[j].type != thisType) { elem.splice(j,1); } // If a type is specified, remove tags that do not have a type attribute
}
}
}
else { // Otherwise, any/all elements in a document/body will be affected
elem = new Array(); elem = document.getElementsByTagName(thisTag); // array of all items of [tag]
if(thisType != "") {
for(j=0;j<elem.length;j++) {
if(elem[j].type != thisType) { elem.splice(j,1); } // If a type is specified, remove tags that do not have a type attribute
}
}
}
if((thisEvent != "") && (thisAction != "")) {
for(i=0;i<elem.length;i++) { // All elements are picked - let's apply some attributes
document.getElementById(elem[i].id).addEventListener(thisEvent,thisAction,false)
}
}
}
HTML Code:
addEventToElement('form_name','input','text','keydown','return numbersOnly(event,this);');
Returning False Ignores OnSubmit Listener
Jul 23, 2005I am wondering about what seems to be a particular quirk in Javascript
that does not allow form event listeners (e.g. "onsubmit=...") to work
properly. In the code below, I would like to set up a function
(doOnSubmit) that is called when the form is submitted.
But there is a "return false;" in the "onclick" of the button. If this
"return false" is removed, the code works as I would hope it would.
With it there, doOnSubmit is never called. Code:
