Hello everybody.

Can I pass a object to a method by reference in JavaScript? Take a look at the code:

<SPAN style="COLOR: #cccccc; FONT-STYLE: normal; BACKGROUND-COLOR: #ffffff"> 1: </SPAN><FONT color=blue size=+1><</FONT>script type<FONT color=blue size=+1>=</FONT><FONT color=purple>"text/javascript"</FONT><FONT color=blue size=+1>></FONT>

The result I expected was 0, but it's still 1. I know I could use:

<SPAN style="COLOR: #eeeeee; FONT-STYLE: normal; BACKGROUND-COLOR: #ffffff">1: </SPAN><FONT color=red>function</FONT> ref<FONT color=blue size=+1>(</FONT>o<FONT color=blue size=+1>)</FONT>

<SPAN style="COLOR: #eeeeee; FONT-STYLE: normal; BACKGROUND-COLOR: #ffffff">4: </SPAN><FONT color=blue size=+1>}</FONT>

But this solution is not what I need.

Is this possible in JavaScript?

Thanks,

Hi there,
It's impossible I think, you might want to check out the core javascript reference[^] for more information. This is an interesting question though.

The idea you got in reply was 'it's probably not possible', with a link to an online reference. 'Any other ideas' does not seem a valid response to me. I doubt very much that pass by reference exists in jscript, and certainly your approach (write a function called ref and hope it passes things magically by reference ) is not going to work.

It may be possible, but neither I nor your other respondent think it is. You should go to a bigger jscript forum if you hope for a better answer. Better yet, if it is possible, google is bound to know about it.

Thank you for explaining minhpc_bk's post to me.

'Any other ideas' means that I'm still asking for help. It's not a reply to minhpc_bk's post. In fact, minhpc_bk's post helped me a lot.

This is just an example, I don't hope it's going to magically work.

Doing so only changes the result property of the dummyArg.value, but not the obj.result. You can see that with:

alert(dummyArg.value.result);

I'm not sure I have other than you'll have to edit the property of the object instead of assigning another object to the function parameter.

PS: Nice formatting! Smile | :)

Thank you again for your reply.

I'm sorry if my previous post was rude. Btw, try this CodeColorizer[^].

Nice. That gave a definite answer right away:

"All parameters are passed to functions by value"

That means that the reference to an object also is passed by value. That in turn gives that you can change the contents of the object, but you cannot change the reference to the object.

But this opens up a different way of doing it. As you can modify the contents of an object, you only have to place the reference inside an object in order to be able to change it from inside the function.

This is an example that shows an object containing a refernce to another object:

function modify(obj) {<br />
	obj.ref = new String("42");<br />
}<br />
<br />
var info = new String("1");<br />
var o = new Object();<br />
o.ref = info;<br />
modify(o);<br />
alert(info);<br />
alert(o.ref);

It will create an object, and then another object that will contain a reference to it. It then passes the object to the function that will replace the reference with a reference to a new object. The code then displays the value of the first object to show that the function has not changed it's value, and displays the value of the referenced object to show that the function successfully changed the reference.

HI
I have a question about a textbox control.
The input can only be numbers and a ,.
It's to input a money value.

Can anybody help me please.

You can use a RegularExpressionValidator to validate the field, with the expression "\d*(,\d*)?". This will allow at most one comma in the input.

1) Hundreds of lines of rubbish, to which nobody (but you) care about
2) No description of the problem other than "Error message blah blah blah" in subject line
3) In addition to 2) not even any info about the error message you recieved

Were you REALLY expecing any sort of answer?

Well, actually there is some more information a bit into the code. First there is the long code of the actual page, then some info, and finally a huge library that is used by the page.

The information is not very informative, though. It's mainly an error message, but without any information on where in the code the error occured.

"no-touch deployment" loads always old winform version

I try do deploy a winform .exe application via internet explorer. The first time when accessed it's ok, but then always starts the old version. As far as I understood, the assemblies are loaded in the download assembly cache and started only from there if the timestamp on the server did not change. It does what it should do on my computer. Can anyone help me with any idea?
Thanks,
Roland.

Hi there,
You may try to delete the download folder in the assembly cache:

gacutil /cdl

Next time, when you run the application, the lastest version will get downloaded.

Hi!
The client PCs have only framework installed, not the SDK. So, gacutil is not available. I tried to delete the physical download assembly cache folder (..local settings\assembly\dl2) - which is exactly what gacutil /cdl does - but can't find it under Win98. It must be in a different folder or have a different name.
Nevertheless - thanks for the reply,
Roland.
