javascript: in location bar

[John Smith]

I am using IE 6.0

from
http://www.javaworld.com/javaworld/j...script-p2.html

I gather that
"If you need to test a number of command lines, you can reduce the
keystrokes by typing javascript: (remember the colon) in the Location
box. Navigator displays a "JavaScript typein" frame at the bottom of
the window. Type the command line you want to try, and press Enter. "

How can obtain a similiar "JavaScript typein" frame with IE 6.0, so
that I can enter *multiple* javascript command lines?

Thanks.

Use a text editor to write normal, indented code - maybe minimize
whitespace other than for indenting. Use find/replace to replace all
contiguous whitespace with a single space. Copy & paste that into the
command line.

When you get it working, save it as a bookmark.

when I paste my mini script at the location bar
javascript:func tion jsinput () {;
parent.MochaInp ut.document.wri te ("<b>JavaScr ipt input</b>");
parent.MochaInp ut.document.wri te ("<form action=JavaScri pt:
target=MochaOut put>");
parent.MochaInp ut.document.wri te ("<textarea name='isindex' rows=5
cols=50>");
parent.MochaInp ut.document.wri te ("</textarea><BR>") ;
parent.MochaInp ut.document.wri te ("<input type='submit' value='Run'>");
parent.MochaInp ut.document.wri te ("</form>");
};

i got the following javascript error:
Expected '}'
(i tried removing all the ; at the end of each line and i still got the
same error)

apparently the location bar is only taking the first line of my script.
If i try putting all code on 1 line, with a ; at the end, i still got:
javascript:func tion jsinput () {parent.MochaIn put.document.wr ite
("<b>JavaScr ipt input</b>") parent.MochaInp ut.document.wri te ("<form
action=JavaScri pt: target=MochaOut put>")
parent.MochaInp ut.document.wri te ("<textarea name='isindex' rows=5
cols=50>") parent.MochaInp ut.document.wri te ("</textarea><BR>")
parent.MochaInp ut.document.wri te ("<input type='submit' value='Run'>")
parent.MochaInp ut.document.wri te ("</form>") } ;

I got a javascript error that stated:
Expected ';'
Code 0

where is my mistake?

The ";" here is merely delimiting an empty statement.
parent.MochaInp ut.document.wri te ("<b>JavaScr ipt input</b>");
The ";" here is required, unless the next statement is on the next line.

For the sake of code style, there should not be a space before the "("; it
is a method call, and the "(...)" part is the argument list that belongs to
the identifier of the called method.
parent.MochaInp ut.document.wri te ("<form action=JavaScri pt:

Apparently that is not true for Gecko-based browsers. A newline in
copypasted code appears to be normalized to a space character.

You do not use a Gecko-based browser, such as Firefox, for testing
bookmarks. JScript's (IE's) error messages are often bizarre, if
not misleading, while SpiderMonkey's error messages are often much
more helpful, because they are often much more verbose. (Remember
the helicopter Microsoft joke?)

The error message I get in Firefox is

That said, your "action=JavaScr ipt:" is utter nonsense.
Search the archives for "pseudo-protocol".

I downloaded Firefox 1.5 and tried typing
javascript:aler t("hello);
on the location bar. I purposedly missed the closing ", and expected a
javascript error message.
Instead once I hit "Enter", the screen does not change. no error
message, no popups, nothing.

Why?

Why?

Because you looked at the wront place.

Choose Tools > JavaScript Console
Press Clear to remove accumulated stuff
Type whatever you want in the Evaluate string and press Enter.
Press Clear again, close the console, type javascript:aler t("Hello);
and press Enter; open console again - here it is! :-)

[John Smith]

Thanks for pointing out "Tools > JavaScript Console".

2 follow up questions:
1) The evaluate string is only 1 line. How do I evaluate a multiline
javascript snippet? Is there a better method than adding ; at the end
of each line and manually combining the say, 10 lines into 1 line?

e.g.
<SCRIPT>

function jsinput () {

parent.MochaInp ut.document.wri te ("<b>JavaScr ipt input</b>")

parent.MochaInp ut.document.wri te ("<form action=JavaScri pt:
target=MochaOut put>")

parent.MochaInp ut.document.wri te ("<textarea name='isindex' rows=5
cols=50>")

parent.MochaInp ut.document.wri te ("</textarea><BR>")

parent.MochaInp ut.document.wri te ("<input type='submit' value='Run'>")

parent.MochaInp ut.document.wri te ("</form>")

}

</SCRIPT>

<FRAMESET ROWS="50%%,50%% ">
<FRAME NAME="MochaOutp ut" SRC="about:blan k">
<FRAME NAME="MochaInpu t" SRC="javascript :parent.jsinput ()">
</FRAMESET>

#2) The above function jsinput() is called by another HTML element
(<FRAME> in this case). How do I include the HTML code in the
Evaluation process?

Because you did not read the FAQ.

Read the FAQ <URL:http://jibbering.com/faq/>, especially FAQ 4.43.

Furthermore, I recommend to install the Web Developer, Console^2,
and FireBug extensions.

I use the JavaScript Console feature from ContextMenu Extensions, and
the Open Execute JS extension for this, unless I create a test case
HTML document.
e.g.
<SCRIPT>
The `type' attribute is required:

<script type="text/javascript">

Will you stop posting the same code over and over again?
Use Message-ID URIs for references if you have to:

Nonsense. <URL:http://validator.w3.or g/>

(Pardon?) You do not. HTML code is not script code.
