View 1 RepliesI've got the following source code: function MyMenu()
[Code]...
I wish to execute the lambda function given at menuEntries[i].action. The list is build, but at a click i've got the error that menuEntries[i] is not defined. What should I do? I think
In 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() {
if(xmlhttp.readyState == 4 && xmlhttp.status == 200) {
[Code].....
Seeing the examples I have noted that you always use lambda functions. Is there any reason for that? why you don't make something like this:
I think is more clear than:
And we can edit and reuse the function easily, also if you are using an editor like Netbeans you can see all your functions in a list.
Even more, I think in some situations is faster a closure because we are not creating a new object every time we pass the function:
Is there any reason for chosing lambda functions?
Can anyone show me how to show an alert box any time ctrl -n is pressed.

I want to execute 2.js first, but I can not touch 1.js 2.js. I need to write

Is it possible to enter or call c++ code blocks from javascript functions? If so, how?
View 13 Replies View RelatedI have the below code in a form to re-form the characters entered into it
into a dollar amount and also only accept numeric characters. However, when
I enter the numbers "113" (which appears after the reformatting process as
1.13), it no longer accepts any other characters. I also am not able to

has any ideas why this is happening.

I have built a form on my network. I have put several javasripts in the form. The thing that is driving me nuts is; while codes such as highlight fields, copy fields and text limit work, others, such as Sentence case and Auto enter curent date don't.

I have some Javascript code that reads and sometimes sets the content of
a textarea. I want this to be reasonably browser and platform independent. My question is, what characters should I expect to find at the end of a line? I suspect that I need to cope with either "" or""; can someone confirm?
Setting the content is more of a challenge. I don't want to have nasty browser detection to select what to use for newlines. Is there one newline pattern that is safe for all browsers?
Could you find out some fault in the codes as below?
Anyway I can't see the correct effect now.
<head>
my users will be filling in a text box, and its contents will be forwarded to another page via a form link. I keep coming across new instances of characters getting converted to %2 codes, eg ! gets changed to %21,' gets changed to %2C etc. At the moment I am replacing these with javascript on the receiving page, but this can't be the best way to do it. And I don't really understand why it happens anyway. Is there a way of making sure what gets typed in gets forwarded correctly? Or failing that, is there a list I can use to find them all?

They both work perfectly fine except when both linked up at the same time. Only the last one will work. I've tried to find how the codes are working when the page loads in order to fix that problem but I cant figure it out for these two specific codes.
Someone fixed this codes, i want the value inside the text fields will empty after submit the form..

One preloads images, controls my mouseovers, etc
The other is my form validator.
What should the correct code be as this one clearly doesn't work.
Obviously I don't know a thing about Javascript.
I want to stop users running html tags and javascripts in my text box. How can I do this?

I'm using a fork of osC for an ecommerce system. It has an integrated smarty template. In the admin section, when adding products there's a section with three tabs: Main Image, Extra Images, and Media
This section acts like AJAX, but I'm not sure if it is. The media pulls actions from two .js files: prototype.js and media.js So, I'm guessing it's Prototype? The problem is adding media works fine in firefox, but only shows a "Please Wait..." when used in IE, Google Chrome, and Safari The odd thing is when it's loading in Firefox, it says "Initializing.." (Instead of Please Wait..) then loads the media functions allowing me to add sound to my products. If it's php I can do fine, but I don't know much about JS.
The reason that it works well in firefox, makes me suspect the code is right, but missing something.

I tried using the range method and wasn't able to get it to do what I needed it to do. I don't want anyone else to see what the list of correct zip codes are, this is to verify that they are local.
