Programming :: Javascript Line Break
Feb 25, 2011
I have some variables that are loaded from mysql - in mysql, the line breaks are not indicated by ' or '<br>' or anything -they are just line breaks. the variable is loaded into javascript and then inserted into a <pre> element. the line breaks are not showing up.
pre1 = pre1.replace(/>/g,">"); - this works well, naturally. but how do i get those line breaks to show up as line breaks in a browser?
I've tried many variations of something like:

I have a big csv-file wich is not formatted very well. I clean it up with removing a lot of html etc, but some of the lines breaks where they are not supposed to.What I want to do is to check next line, if it starts with 'PX' I don't want to do anything, but if it does not start with 'PX' I want to merge the two lines. That is removing the newline character on line one and replace it with a space.Can this be done with sed? (or maybe with perl or something, but I'm more familiar with sed)I've been looking und the net to find a solution, but to no result.

How can I verify JavaScript on a site (not on the same server) is working from command line access of the URL?
On checking some of what was written in 2005 I find most of it isn't still relevant (if it was then - I noted the w3m-js stuff mentioned in 2005 hadn't been updated since 2003).
Since then a couple of times I've looked into it but didn't make much headway but also didn't spend a lot of time on it. So far as I could tell from other posts I'd seen others hadn't either.
Recently I found out about Mozilla's SpiderMoneky js library and that it could be linked into elinks text browser and did same on my RHEL5 system.
I found Spidermonkey rpms in the EPEL (Fedora sponsored) repository:
js-1.70-8.el5.i386.rpm
js-1.70-8.el5.x86_64.rpm
js-devel-1.70-8.el5.i386.rpm
js-devel-1.70-8.el5.x86_64.rpm
I was able to download and install using rpm then compile elinks from source to include the above. Running elinks version after that shows the ECMAScript support is compiled into the new elinks binary. Also setting various ecmas* flags in the elinks.conf does have effect so clearly it is using them. (As opposed to another system where I use the original RHEL5 provided elinks RPM it complains about the ecmas* stuff being invalid options.)
It appears that by default it has this enabled but just for good measure I added:
set ecmascript.enable = 1.
Despite that when I pull up the page I see:
This product requires use of a browser that supports JavaScript
As a test I set the above to 0 on the off chance it was backwards and saw the same thing.
I then set the following:
set ecmascript.error_reporting = 1
On pulling up the page I now see a popup box:
Quote:
JavaScript Error:
A script embedded in the current document raised the
following exception:
TypeError: Window.Focus is not a function
OK
That seems to suggest that despite the earlier message about needing a browser that supports JavaScript that it is in fact executing at least one JS but that it is getting an error. Can anyone confirm that?
Does anyone have any idea what I�d need to do to deal with the Window.Focus message?
Essentially the site is a login page and even though I am able to input username and password after opening in browser when I tell it to POST it simply returns to the same login/password page.
And of course it doesn't have to be elinks/spidermonkey. I'd be interested in finding out if anyone knows a way I can verify a site that is running JavaScript is actually responding properly from command line rather than via a browser?
The SpiderMonkey stuff from Mozilla when compiled into elinks is supposed to do that but given my results Im not sure if it is or not.
Most of the documentation I can find on JavaScript stuff appears to be aimed at developers testing their own JS code from command line rather than accessing a web page with JavaScript.

I want to know that how the break points and watch points work in the GDB. I know the GDB works on symbol table. But would like to know more details of it. How watch points differ from break points.

There is this sample web page: [URL] and it has a clickable link / button that executes a JavaScript function: (Right-Click and Copy Shortcut would give this piece of code)
Code:
javascript:__doPostBack('lbtnUpdateStatus','')
whereas the source code for the link / button is as follows:
Code:
<a id="lbtnUpdateStatus" href="javascript:__doPostBack('lbtnUpdateStatus','')">
I want to automate the above function / link along with the said URL so that I won't have to open the webpage and click the button / link. I want a single URL hitting which we won't need to do the extra effort of "clicking the link / button" that executes the JavaScript function given above. I can't automate this task in the source webpage itself because that has to be there as it is for the users who access the webpage. How to achieve it?
I got some useful information here: [URL] but I want to call a javascript function along with a URL such as this:
Code:
[URL] javascript:alert("OKAY")
but the above line of code won't work.

I went to [URL] the other day, and I'm really impressed with the way, when you click on domain, it adds it to the cart WITHOUT A REFRESH. But what I really want to know is - how does it do the slick little effect when you click "Add to basket", when it "appears" on the right hand side?

Lets say I have a site "Website1.com"
On that site I want to run a little javascript that verifies that the site was accessed as "Website1.com" and not "dev-Website1.com"
If it was accessed correctly, nothing happens. If it was accessed incorrectly, it displays an error saying "You are trying to access this site incorrectly."
What is the simplest way to accomplish this?

I am using window.onbeforeunload to keep people from accidentally leaving. I was hoping to intercept this event, run my own dialog box and load another page that closes the window, or of course, cancel.
I'm needing this because my site is a single page and I can't figure out how long people are visiting for, if I could load an exit page, then I can figure this out.

In my book, this is an example of a recursive algorithm:
var reverseArray = function(x,indx,str) {
return indx == 0 ? str : reverseArray(x,--indx,(str+= " " + x[indx])) ;; }
var arr = new Array('apple','orange','peach','lime');
var str = reverseArray(arr,arr.length,"");
alert(str) ;
I'm trying to understand it, I'm stuck at the (str+= " " + x[indx])) part - that part of the function definition expects an ARGUMENT, am I right? What's being passed to it is a bit of PROGRAM, the str+= stuff. So - how is it working?

When someone is speaking into the mic, I'd like a "level meter" such as the one that comes with gnome sound recorder, that flashes up and down when a sound is made or somebody talks.This will be done in Javascript, using the brand new "Rainbow API", i.e. inside the browser.I know nothing about audio programming, so - where would I get *started* with something like this? Could anyone tell me at least WHAT to Google?

I'm loading an XML file stored in a tiny web server (based on lwip). This web server is not very cooperative and is not marking the http content-type as "text/xml". As result, Firefox is not recognizing the file as xml (IE does) so I can't use DOM methods for parsing the xml file. overrideMimeType("text/xml") should help me avoid this problem but, even having overrided the mymetype, the content-type received is still "text/plain". This is a portion of my JavaScript code:
Code:
var xmlObj;
// loadXMLdata is called from the html file
function loadXMLdata() {
var dataFile = window.location.href.substring(0, window.location.href.lastIndexOf("/") + 1) + "config/myfile.xml";
if (window.XMLHttpRequest) {
xmlObj = new XMLHttpRequest();
// This should override the mimetype...
if (xmlObj.overrideMimeType)
xmlObj.overrideMimeType("text/xml");
xmlObj.onreadystatechange = fillXMLdata;
xmlObj.open("GET", dataFile, true);
xmlObj.send("");
} else {
alert("Your browser can not handle this script");
return; } }
// fillXMLdata is called from loadXMLdata once the xml object is ready
function fillXMLdata() {
if (xmlObj.readyState == 4) {
// Here Content-Type shows again "text/plain"
alert(xmlObj.getAllResponseHeaders());
var xmlDoc = xmlObj.responseXML.documentElement;
// And here section is null
var section = xmlDoc.getElementsByTagName("section")[0]; } }
The xml is quite simple:
Code:
<?xml version="1.0" encoding="iso-8859-1"?>
<section>
<item>1</item>
<item>2</item>
</section>

I'm working with javascript and trying to replace all instances of a Roman character in a string with nothing. How do I assign var reg to all Roman characters? In UTF8, capital letter A is U0041 and at the other end, small z is UFF5A.
So, I'd like to do something like:
var reg = u0041 - UFF5A;
str1 = str.replace(reg, '');
I think you get the idea. I have no idea if that can be done. The idea is to take this string (for example): str = make a door-to-door[house-to-house] visit / ring every doorbell." And take out all the Roman characters and define it as str1. And then take out all the Korean characters (u1100-uFFDC) and define it as str2. In fact, a WAY more useful thing to do would be to replace the instance of this: [u1100-uFFDC]+" "+[u0041-UFF5A] with [u1100-uFFDC]+","+[u0041-UFF5A] so that the output would be a .csv file.

I'm looking for javascript tutorials or books that meets the following criteria:
1. Very thorough: Starts with the most fundamental concepts and progresses logically from basic to advanced concepts, without skipping over important ideas for the sake of expediency.
2. Lots of small practice exercises that parallel the concepts and syntax being learned.
I've looked at a lot of tutorials, but they all tend to be lacking in one of these areas or the other.

I have a large text file with three columns. I'm trying to write a PERL script that splits the file up based on the value of the 3rd column. So every time the third column reads 0, a new file is created and all the data up until the next 0 is found is written to that new file. This should happen over and over until the initial file has been entirely split up.
ex data:
000
2024
2243
2143
96962871
97972878
000
2034
3034
3352
So with the data above, the file would be split into two files:
data_1.txt would contain
000
2024
2243
2143
96962871
97972878
and data_2.txt would contain
230
2034
3034
3352

I am trying to set up a webpager that contains a background of the skylouds uperimposedin the center will be an image of an airplane with a transparent background.I want the sky to scroll continuously to the left behind the airplane. I am having problems with the background not being visible, not moving as expected, the airplane not being visible, and just disappointment in general.I think the background of a div will not be visible if there are no internal contents because it will be sized to zero. So I introduced another transparent image to force the size of the main div. Still no joy.Here is my code. Note that I don't have my timers set up yet, just a button to test background movement.

I have two files, file1.traj and file2.traj. Both these files contain identical data and the data are arranged in same format in them. The first line of both files is a comment.
At line 7843 of both files there is a cartesian coordinate X, Y and Z ( three digits ). And at line 15685 there is another three digits. The number of lines in between two cartesian coordinates are 7841. And there are few hundreds of thousands of lines in a file.
What I need to do is copy the X Y Z coordinate (three digits) from file1.traj at line 7843 and paste into file2.traj at the same line number as in file1.traj. The next line will be 15685 from file1.traj and replace at line 15685 at file2.traj. And I dont want other lines (data) in file2.traj get altered. This sequence shall be going on until the end of the file. Means copy and substitude the selected lines from file1.traj into file2.traj.
I tried to use paste command but I cant do for specified line alone.
Here i showed the data format in the file. I used the line number for clarity purpose.
