One person says the return should go inside the try because otherwise during runtime a null pointer exception (NPE) can be thrown. The other says they tested and never got an NPE - even if the value didn't exist, abc[0] returned an empty object (the test showed it returning empty curly braces).
Must the return go inside the try or is it ok to be outside as in the above snippet?
i cant find a way to return a value to a function inside a class...seem that when try to output it(the code with red markup)..its output is undefined..

I have a calendar where i write my events. If I have 2 events in the same day, how to put a carriage return between the events in the alert part of message? For example, I want this alert message:
Event one to the office. Event two to the store.
The string that I use actually is:
fAddEvent(2003,9,17," Event one. Event two.","alert('Event one to the office. Event two to the store.');","#00ff00","red");
I'm working on a project that requires me to send stuff through an AJAX $_GET request to a PHP page which then echoes a string which then is fed back to the form on the first page.
So the GET url looks something like this:
Code: dataminer.php?question=kassasumma&q=500&kale=10%&nro=6 I have tried to escape that URL with various escaping methods including Code: escape()
[Code]....
but, with no luck. The server keeps giving me a 406 Not Acceptable and it's because of the percentage sign (which is essential) in the url.
I am trying to find a format for a string that could be used to instantiate a Date object which would include only a month and a year.I can't find documentation on what formats of dates are accepted.
question: if you want a link which simply runs a js function is it acceptable to have no href? the problem with this is the cursor doesnt change when you hover over, but if you put # as the href it jumps to the top of the screen which is sometimes unacceptable. what it the best solution to this? granted you could do event handling behind the scenes and just intercept the clicks and prevent the href from going anywhere, but sometimes you just want to stick an onclick on the anchor tag!
I'm working on a very Javascript heavy application, and we've set up a number of different Objects to handle the data on the page. Very often, we'll need to send all of the data from these objects to PHP. Right now, we're using JSON.stringify. Are there any issues with this? It seem's like it does exactly what we need, but are there any downsides?
with jquery, i try to get the margin-left ($('#mydiv').css('margin-left'), but the function return 0px, unable to retrieve the good value (auto) anyone has idea to retrieve the value "auto" when margin-left is "auto" ?
I've been searching for about 3 days on this topic. I'm trying to get a template field inside of an ASP.Net detailsview control inside of an ajax updatepanel to work with the jquery datepicker. Very frustrating! I'm using VB with VS 2010. I can get the datepicker to work fine with a simple text box inside of an update panel but when I put it inside of a detailsview control it stops working.
var obj = {}; with(obj) { var x = 10; } print(x); print(obj.x);
It prints 10 and undefined. Here, one could expect that obj.x get the value 10. But it's not the case, because variable declarations are placed at the start of function code (or global code), so the previous code is equivalent with:
var obj; var x; obj = {}; with(obj) { x = 10; } print(x); print(obj.x);
You can clearly see now that x is placed in the outer context. But consider the next:
var obj = {}; with(obj) { eval("var x = 10;"); } print(x); print(obj.x);
I was expecting that obj.x would get the value 10 here. But no, it gives the same output as the previous code. I tested it with spidermonkey, kjs and ie jscript. Looking at the ECMA spec, I could not find anything that describes that behaviour. Code:
I have this in my javascript code but have no idea on how a returned value works/where does it return to? what do i do/or can i do with a value that gets returned?
I am asking this so i can learn on how to use it cos i am new to all this and dont know how it works...
Do you have to use the onClick attrib to have return false work?
i.e. is it possible to do <a href="javascript:somefunct();return false;"> and have the page not reload with 'false' or the browser not complain about illegal use?
I have a form on a web page that requires to click on a button to submit the information. I have two questions about changing this form: 1. Is there a way that I can change the script so that the form can be submitted by hitting the enter key?
2. Is there a way that I can have the Username and Password boxes cleard after the form is submitted?
You probably don't need the code for the form as it is pretty basic but here it is just in case.
i am using ajax but this is the problem in js it is giving me a NaN when i goto check the output. on two different servers two different responses on my localhost test environment i am getting the correct info and on the server online i get NaN response. i am using this to set the width of my hp bar
Code: document.getElementById("ehpBar").style.width=count1+"%"; and count1 looks like this Code: var count1 = hp/basehp*100;
i have tried rounding it and everything and i just get the same stupid NaN error. I can use each variable by itself and it outputs the correct number on both servers and then when i try to divide it NaN on one server and works perfectly on the other. I know it is probably something simple i am just missing it.
Afternoon all, Have a pretty simple function, that requests a number to be entered. I want to return that number, but i seem to be typing something wrong in the return value.
function newFunction(a, b) { var newArray = new Array(a); for (var i = 0; i < 5; i = i + 1)
I am populating a field on my page using a php include. I am asking javascript to update another element with that field's value. The value written to the select input box is Ƈ:Any Provider'. The process works fine in Firefox. In IE6 it does not write. the value nor does it throw an error. What am I doing wrong?
function postthis(){ var provider = document.inputForm['provider'].value; var report = document.getElementById("status"); var message="The Value of Provider Block is: " + provider; report.innerHTML = message; }
In firefox, "The Value of Provider Block is: 1:Any Provider" is written in the report element. In IE6, "The Value of Provider Block is : " is written in the report element.
I know the answer must be yes, but I am really having a hard time figuring this out. I have a simple script below, that calculates age (I know I need to do some more work). I want to redisplay the value returned from the function. It works OK, because the result displays correctly in the alert. Code:
I'm having a problem. I was able to get the edit working fine. I was able to get it to hide the current div and go to a different div. When I combine the two, the edit works but I cannot go to the different div.
I have a form and a submit button .on clicking submit button function validate call.this function call another function (say func) .this func function vallidates some input and return true or false value to the validate function this then return true or false value to the submit button .I want that func directly return true or false to the submit button.
Is it necessary to return a value from the event handlers? For instance, what does the return value in the following code signify? What will be its impact if it returned otherwise (true)?
