I have a nodejs TCP server and a client. Basic network communication happens. Client sends "data + STX_CHARACTER + data + ETX_CHARACTER" (just an example).
How do I split the string using the STX Control Character as a delimiter or how do I reference the character at all in Javascript.
Hi
Does anyone know what's the replacement method for FB.CanvasClient.startTimerToSizeToContent() to resize iframe content in the new javascript SDK for Facebook?
Or maybe if there is an alternative technique for achieving the same effect?
Thanks

I have a 24 hour time string (ie 16:30) and would like to add x time blocks of 30 mins. For example if x = 4, then 16:30 + 4(30) = 18:30. Is there any easy way to do this with out exploding the string and doing if statements for mins/hours.. etc? Also this is on a php page would it be easier to do this in php then echo it to the javascript?
Thanks for the help!
I got the Wrox.Beginning.JavaScript.3rd.Edition and wanted to start learning it from scratch, then my boss came along and said that why bother, learn jQuery.
Can I understand jQuery and work with it although I am a newbie and have limited knowledge in ASP.net, vb.net, some C#, and basic HTML?!
For example,
<html>
<body>
<img id="pic" src="original.jpg"/>
</body>
</html>
In Javascript (jQuery):
$("#pic").attr("src","newpic.jpg");
Now, is there a way to reset #pic's src to original.jpg without explicitly setting it as $("#pic").attr("src","original.jpg");?
Hello!
In my javascript i want to open URL in new window with this method:
var win = window.open(url...);
How can i check this, not to open the same window and lose all inputted data.
For example, if i opened "www.musite.com/addproduct" URL in new window, input data, leave my work place. then i click open window again, new window open and i lost all my data.
I work in Javascript with integer numbers only (mainly adding numbers and shifting them). I wonder how big they can be without loosing any bits.
For example, how big X can be such that 1 << X will represent 2^X ?
Hi,
I have a website in php which is using 4 frames(top, left, middle and right). The middle frame
contains the web user control coded in asp.net. Now, in the right frame( which is coded in php ) some javascript contains the id of the items selected in right frame. I need to get those ids to the middle frame on asp.net user control. How can i do this?
How can i achieve http://jdstiles.com/java/angledtext2.html this kind of angle(slant) using html , css and javascript. In design we have tabular structrer and by clicking on a tab the area beneath should refresh without reloading page (some thing like jquery or ajax).
I'm doing some research for a JavaScript project where the performance of drawing simple primitives (i.e. lines) is by far the top priority.
The answers to this question provide a great list of JS graphics libraries. While I realize that the choice of browser has a greater impact than the library, I'd like to know whether there are any differences between them, before choosing one.
Has anyone done a performance comparison between any of these?
I'm using a classical javascript prototypal inheritance, like this:
function Foo() {}
Naknek.prototype = {
//Do something
};
var Foo = window.Foo = new Foo();
I want to know how I can improve this and why I can't use this model:
var Foo = window.Foo = new function() {
};
Foo.prototype = {
//Do something
};
Why this code doesn't work? In my head this is more logical than the classical prototypal inheritance.
My layout breaks if I change the window size in IE7/AOL, so I added a simple javascript function that fires on window.onresize, but no matter how I change the location I get problems.
It was suggested I post a link and here it is:
link text
I already use PHP to detect browser and include an IE7-only inline stylesheet (and for mobile browsers), and my page looks nearly identical to the way it does in FF, Opera, Chrome, Safari and IE8, but when I change the window size, some things go wonky, and come back into line if you refresh. Any advice is welcome :)
I'm making a call to PayPal's credit card processor, and after a successful/unsuccessful transaction it returns me a string that looks like this:
DoDirectPayment failed: Array ( [TIMESTAMP] = 2010%2d05%2d02T23%3a33%3a28Z [CORRELATIONID] = 8c503f5c6c861 [ACK] = Failure [VERSION] = 51%2e0 [BUILD] = 1268624 [L_ERRORCODE0] = 10527 [L_SHORTMESSAGE0] = Invalid%20Data [L_LONGMESSAGE0] = This%20transaction%20cannot%20be%20processed%2e%20Please%20enter%20a%20valid%20credit%20card%20number%20and%20type%2e [L_SEVERITYCODE0] = Error [AMT] = 90%2e00 [CURRENCYCODE] = USD )
I'm not a javascript pro, but how exactly can I turn that into a parseable array?
Thank you!
How can I tell if a google bot is reading my javascript generated content?
I have an AJAX script that generates some text dynamically on a page... this content does not change by user, but simply by date/time.
I am not sure how I can tell if google sees it.
In the scenario below, how can I get references to the variables declared during eval()?
function test() {
eval("var myVariable = 5");
var locals = magic() // TODO What should we do here?
alert(locals["myVariable"]); // returns myVariable
}
Just a note: JavaScript being evaluated comes from a trusted source.
Is there is way to compress JavaScript code?
e.g.
function test(){
// some code here
}
after compression it should be
function test(){//some code here}
Also, I need vise versa at the time of editing the code.
Hi,
In my html, I have an html element with a mouseover event handler.
Can you please tell me if it is possible for me to invoke that event handler programmically in JavaScript?
Thank you.
I am searching for an expression builder GUI (like the one used in Microsoft Access). It can be plain Javascript or JQuery plugin. I am loathe to build my own and reinvent the wheel if one already exists - and yet, a search on Google does not find anything remotely useful.
Is anyone aware of any such library/plugin or article that covers this?
In Python I can use the iterkeys() method to iterate over the keys of a dictionary. For example:
mydict = {'a': [3,5,6,43,3,6,3,],
'b': [87,65,3,45,7,8],
'c': [34,57,8,9,9,2],}
for k in mydict.iterkeys():
print k
gives me:
a
c
b
How can I do something similar in Javascript?
I'm trying to use the replace function in JavaScript and have a question.
strNewDdlVolCannRegion = strNewDdlVolCannRegion.replace(/_existing_0/gi, "existing" + "newCounter");
That works.
But I need to have the "0" be a variable.
I've tried:
_ + myVariable +/gi and also tried
_ + 'myVariable' + /gi
Could someone lend a hand with the syntax for this, please. Thank you.
