I wanted to write my own script for a fade-in animation, since the ones I have found have got too many options or need some framework, which makes them unnecessarily big. I wanted to learn too.Unfortunately, the code didn't work as I wanted, and I commented some things so as to find out what's happening.Why is an object reference assigned to what was previously a string?
View 6 RepliesI have a button that when you click it displays the results of my db in a div. What I am trying to do is to get the results to update every five seconds.
I thought setTimeout was the best way to achieve this. However I am getting the error message that ID is not defined on the setTimeout line. I thought it would automatically input ID into the fields marked ID when the onloadXMLDocRefres ('File.php','txtHint') button is clicked?
The button works to load the script, but the refreshing the div is not.code...
I've just realized that in Mozilla pointer variables always have local scope in a function. Unlike IE. I wondered if Mozilla was able to do it in some other way? readXML() is an init() function which might be a constraint - I'm no javascript expert.
// The following won't work in Mozilla.
var record;
function readXML()
{
record=xmlDoc.getElementsByTagName("record");
}
alert(record[0].childNodes[1].firstChild.nodeValue);
I'm having trouble letting functions I defined in jquery read javascript global variables I defined elsewhere.. for example I have a function defined within my jquery

View 1 Replies View RelatedI created this code for a sliding panel and it works well. But I'm struggling to take the object oSidebar out of the global scope. I would prefer that it were a property of the clicked event object. That is, I want to be able to use 'this.oSidebar' within the click event. I've posted the whole page here along with the click image.

I have an external js file used by an html page but I want to use global variables defined in the html page in the js file. for example...
<html>
<head>
<SCRIPT type="text/javascript"
var test = "1";
</SCRIPT>
<SCRIPT type="text/javascript" src="jscript.js">
</SCRIPT>
</head>
So I have var test which is defined in my .html but my jscript.js also uses the variable. I am doing it this way because I have a lot of pages that are simular using the jscript.js functions but each page has different quantities and values of variables used.
but I just can't figure it out. I have trawled the net for a solution and tried many different things that I have seen but still no luck. Maybe the answer is staring me right in the face and I just can't see it. The code it executing the first time but as the setTimeout tries to start the second loop I get an error 'box is not defined'.
function expand(box) {
var box = document.getElementById(box);
var originalHeight = parseInt(box.style.height);
var inc = 5;
newHeight = (originalHeight + inc);
box.style.height = newHeight + "px";
int = setTimeout('expand(box)',100); }
In the function 'formToArray' the variable 'max' is causing a conflict in my application. The reason being that max is not explicitly defined as a var so it becomes a global variable.So IMHO:
#520 - var i,j,n,v,el;
for(i=0, max=els.length; i < max; i++) {
should be changed to
#520 - var i,j,n,v,el, max;
for(i=0, max=els.length; i < max; i++) {
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?

I know it's something stupid I'm doing but I can't figure it out. Essentially I'm trying to load two objects with URLs with two websites that can be loaded(displayed) and unloaded(hidden) at the click of a button.
I've spent an hour trying to debug this and I'm at my whits end! I'm doing this with changing the width and height of the divs that contain the objects that will load the websites. But, in Firefox I get an error in the error console saying : loadUnload is not defined. why? code...
I'm trying to access some of the global's inside my class LiveSearch
and I have no idea how to go about it. Here is what I have so far:
<script type="text/javascript" src="query.js"></script>
<script type="text/javascript">
function LiveSearch(global) {
this.theglobal = global;
this.initialize();
}
LiveSearch.prototype.initialize = function() {
$("#thebutton").mousedown(function() { //when we click the button
alert(this.theglobal);
});
}
$(document).ready(function() {
var objSearch = new LiveSearch("globalvalue");
});
</script>
On page load I create a new LiveSearch instance and it assigns
theGlobal = "globalvalue" and proceeds to initialize(); At this point
Im using JQuery to setup an onmousedown event on a button on my page
with id="thebutton". When I click the button the alert comes back with
'undefined'. How can I get direct access to my theglobal variable? Code:
I think I've had JavaScript variable scope figured out, can you please
see if I've got it correctly?
* Variables can be local or global
* When a variable is declared outside any function, it is global
regardless of whether it's declared with or without "var"
* When it is declared inside a function, if declared with "var", it's
local, if not, it's global
* A local variable that is declared inside a function is local to the
whole function, regardless of where it is declared, e.g.:
function blah() {
for(var i ... ) {
var j ...
}}
i and j will both be visible within blah() after their declaration.
* the notion of "function" in this context also applies for this kind
of construct:
var myHandler =
{
onClickDo: function()
{
in the sense that whatever one declares inside onClickDo with "var"
will only be visible inside onClickDo. What else, am I missing anything?
I am facing a problem in passing replace() function as an argument in user defined java function.
intention is to pass a file path to my user defined function, but before passing the path i want to replace the character '' to '\'
I am posting my javascript function here:
<a href="#" onclick="OpenDocPreview('<%# Eval("PATH")%>'.replace(/\/g,"\\"), '<%# Eval("Filename")%>')"><%# Eval("DocTitle") %></a>
function OpenDocPreview(url, docname) {
alert('message from search base : ' + url + ' ' + docname);
}
I'm using the Google AJAX APIs, but some reason google.load works when run through normal javascript, but if I call the method from my jquery ready function it doesn't work. Code and output is below
page.html
<script type="text/javascript">
loadGoogleStuff();
function loaded() {
console.debug("in loaded function");
}

window.loadFirebugConsole is not a function If I comment out line 3 in code.js, the console debug runs okay, so the ready function is running okay. Even though there's a reference to Firebug, the same error occurs in Safari too. Nothing on the page loads.
I'm just starting out with Javascript as a development language and this will probably be a relatively simple problem for someone to solve for me.
I am trying to access a variable (this.bodyEl.innerHTML) from within a function but get an error message indicating that it is "undefined". I know that it is a valid variable because I call it elsewhere outside of the inner function itself.
I'm sure this is just a scope issue, but I'd welcome any suggestions on how to solve it with an explanation of where I've gone wrong if you have the time.

Not sure if this is possible, but I have an external script that creates an object, and I want to overwrite some of its functionality, but keep the scope.
Here is a basic example:
Code:
<script>
Obj = function (userConfig) {
this._init(userConfig);
[Code]....
I want it to log two Objects, but instead I get two window elements. Is this because I am declaring the functions in the global scope, and not from within the object?
Anyway I can keep the scope of the object, whilst still overwriting the function?

I'm trying to make a time script for an app I'm making (this is not an HTML document; it's a .js file to be used with Titanium) however I'm having trouble getting the function to display and update.
function updateClock()
{
setInterval ( 'kiTime()', 1000 );
}
function kiTime ()
{
//Get current date and time
[Code]...
If I use kiTime() under the text field I will get the current time (or at least the time the app was opened), however if I call updateClock() it's blank.
I can't use the value returned by $.post() method out of the scope of success function.
For instance in below example myvar alerted as empty even though var is alerted with a value. Besides, hide does not work in the scope of success function.
I'm making some changes to a google chrome extension I made and am having some trouble. Heres my code on a content script page (removeAttr.js) :
chrome.extension.sendRequest({greeting: "whitelist"}, function(response) {
var whitelist = response.whitelist;
console.log(response.whitelist);//working
});
alert(whitelist);//alerts "undefined"
How do I acess the whitelist variable from outside the sendrequest() function?
Iv tried saving it to a window.var variable with no luck. Iv tried creating a div and assigning it's innerHTML as the whitelist variable and getting it later with no luck. The fact that it's a chrome extension complicates things because i dont actually know if i can create elements from where the script is located.
I want to change the elements class name dynamically when mouse is out with respect to that element.I want to change the class name after some delay (i.e, i am using settimeout function).
var ulNodes = getElementsByClass("nice-menu");
var liNodes = null;
for(var i = 0; i < ulNodes.length; i++) {
liNodes = ulNodes[i].getElementsByTagName("li");
for(j = 0; j < liNodes.length; j++) {
if(liNodes[j].className == "menuparent") {
liNodes[j].onmouseout=function(){
timer = window.setTimeout(function (){
this.className = "menuparent"; //My problem is with //this line
},4000);
} } } }
I need to set the elemets class name to "menuparent" after some delay after the pointer moves away form that element.
-> When ever i say alert(this.className); in the setTimeout function, the alert box says undefined.
-> I can succesfully alert any where else in the mouseout function except within the settimeout function in mouseover function of that element.

I have a .js file that receives a value from an html page. I'd like this
value to be a global variable that all functions in the .js file can use. I
have tried just declaring a var at the top of my .js file, but when the
value comes into the function and gets assigned to that variable, it is not
global.
