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?
How can I modify any one of these global variable identified via a function
argument?
var x1 = "bla";
var x2 = "bla";
var x3 = "bla";
function modify(variable) {
???? [variable]???? = "blabla":
}
The following onclick should change the string value of variable 'x1' from
"bla" to "blabla", via the above modify() function.
<a ... onclick="modify('x1')">

View 2 Replies View Relatedhow to you use the result of a function as the argument for another function instead of passing the actual function to it. i.e.
function foo2(){}
function foo(func){}
foo(foo2);
This passes foo2 to foo, can I do foo(foo2()) ? i.e. is the difference between whether a function is passed or evaluated dependent on whether you use "()" after the function name?

View 8 Replies View RelatedIn 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() {

I just don´t know the right syntax for this:
I want to change the css class of the li element from the name hidden to the variable filterVal, but i don´t know the right syntax.
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.
Ok...so here is what I have:
function myClass() {
this.checkLogin = function(name,pwd) {
if(name.length > 0 && pwd.length > 0) {[code]....
Everything works above. The first alert shows that this.status was set to 'error'. However, if I call myClass.getStatus(), I get undefined. How can I get the parseData function to set the variables in the parent function?

I'm having problems with the jQuery 'if' statement. When the div 'accord3' is hidden, I'd like the class 'linklast' to be added to 'Schools' --> the bottom corners are rounded. When the div 'accord3' is visible, the bottom corners must be square, meaning the class 'linklast' has to be removed. This has to be able to switch back and forth while I toggle the visibility.
