I've got a function displayResults(imageArray); that first calls removeElements(); to get rid of the currently displayed list items. Both functions are part of class function eventBox(array, string, date). both displayResults(imagearray); and removeElements(); have been bound to eventBox(); by e.g. this.removeElements = removeElements;
However, from within displayResults(imageArray); this.removeElements(this.identifier + "eventsul"); evaluates to "undefined". Also, this.identifier called from within the function also evaluates to undefined (it doesn't in other functions). For some reason I can't access global functions and variables from displayResults(imageArray);. Any ideas?
Here is the code for displayResults(imageArray); :
I'm using jquery to make it easy for AJAX calls.
So I create a class: function cMap(mapID){//vars and stuff}
I go and prototype a function: cMap.prototype.loadMap = function(){ //jquery AJAX call }
Now in the jquery $.ajax({...}); call, I use an anonymous function on the "success:" call: success: function(data){ this.member = data; }
My problem is that inside this anonymous function call I'm trying to call a class member of my cMap class to store the data in from the AJAX call, but it's out of scope. So the JS console in FF/Chrome throws errors about bad value/doesn't exist.
How can I access this class member from inside an anonymous function? Or at least what's a good way to go about doing all this?

I need to traverse all elements of a form & change the color of the label text inside divs. I use a label inside a div to keep texts in columns but only change the color of the text not the entire div. If there is another way please let me know, I prefer css not tables.I have tried many versions but none work because "lab below" is undefined.

I've always wonder if there is diference when declaring and
initializing a varible inside/outside a loop.
What's a better practice?
Declaring and initializing variables inside a loop routine, like this:
for(var i=0; i<list; i++)
{
var name = list[i];
}
or outside a loop routine, like this:
var i;
var name;
for (i=0; i<list; i++)
{
name = list[i];
}
or are both the same....
As a programmer, i always try to practice good programming. I always
thought that by declaring and initializing the variable inside the
loop, i was creating a new memory space every time instead of just 1
time...
What do you think?
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.
all on the same page that are accessed by the classic show/hide DIV functionality.
So user clicks button 2, which shows story 2, hide stories 1 and 3. (all on the same page).
The issue is that I've been asked to provide a method to directly link to story 2 or 3, which currently isn't possible since you need to load the page, then click the button to show story 2 or 3 (naturally 1 loads by default).
So I'm looking for any method to go right to story 2/3 from a link.
Perhaps I can pass a variable through the URL which executes the function as soon as the new page loads (which would mean a quick double page load but I could handle that)
Here's the function:
var showMe = function(me) {
document.getElementById(me)["style"]["display"] = "block";
}, hideMe = function(me) {
document.getElementById(me)["style"]["display"] = "none";

I'm not an ace JSer by any means--the problem I'm about to pose could easily be solved with pointers in C++ (the language with which I am most familiar), unfortunately that is not an option.I am making a webapp using the google visualization API:URL...My problem may be related to the API, but I think it's more Javascript oriented--the Google group for the API is helpful,I have a function, drawDash(), which declares some elements of the visualization, some filters for the visualization, then binds them together and draws them. Now what I need to do is access the elements of one of those vars, specifically a filter, and add/change properties of it with an HTML form.
I've set up an onclick function for a set of checkboxes in my form that calls another function. The problem I face is that I can't really access the filter correctly.[code]So basically, I want to have a function be able to edit the var serviceSearch from another function.
