I see the use of Javascript replace all over the web. What are all the
character sequences? (sorry I am a bit of a newbie at this).
i.value.replace(/[^d]+/g, '');
I understand that /g is global and /i is case sensitive, but what are
the rest? I am asking because I am trying to write a function that
takes an input and replaces everything but numbers and a . (for decimal
numbers).
consider this code below:
var toremove = "some";
var tolook ="I am looking for some other text in this string toremove";
if i do this:
tolook = tolook.replace(/toremove/gi,'');
will to look replace the text inside the toremove variable, or will it
just replace the variable name?
I want to remove from string a <span> tag, but with leave the value of
that tag.
I have that code:
theExp = new RegExp("<span>", "g");
txt = txt.replace(theExp, "");
theExp1 = new RegExp("</span>", "g");
txt = txt.replace(theExp1, "");
and this works only with FF,
With IE it doesn't remove the tag.
With Opera the same
I don't think this is "do-able" but thought I'd better check. Say I
want to replace certain names in some source code as long as they are
not properties (dot properties) of objects. I could use a regular
expression like:
rx = /(?:(.)|)(?:name1|name2|name3)/g;
map = [];
map["name1"] = "a";
map["name2"] = "b";
map["name3"] = "c";
source = source.replace(rx, function ($0, $1) {return $1?
$0:map[$0]});
Dot properties like .name1 are not replaced by anything new and they
need to be "skipped" over by this regular expression but other name1
identifiers need replacement with "a".
One problem with this approach is that dot properties like .name1 are
replaced by themselves and this is just unnecessary work. Something
like a "false" return to skip replacement would be nice but the
following doesn't work.
source = source.replace(rx, function ($0, $1) {return $1?
false:map[$0]});
There are other ways to get around this by using something else
besides replace() but I wanted to see if it could be done with the
replace() method.
I've a function like this: Code:
function submit_msg() {
if (egsd.value == 'yes') {
write_msg("<b>" + chatkeo.value + " : " + chatmsg.value + "</b><br />");
} else {
write_msg(chatkeo.value + " : " + chatmsg.value + "<br />");
}
chatmsg.value="";
}
Now I need to do some string replace in chatmsg.value, ie, I need to look for some piece of text in chatmsg.value, and in case they are present (there may be multiple occurences of the same), to replace them with something else. This is what I got by doing a google search: Code:
function replaceAll( str, from, to ) {
var idx = str.indexOf( from );
while ( idx > -1 ) {
str = str.replace( from, to );
idx = str.indexOf( from );
}
return str;}
chatmsg.value = replaceAll( chatmsg.value, "string to replace", "new string" );
And I place this second function just above the previous one. But it's not working. Any help friends?
I have a little Ajax script and I'm trying to remove some CSS elements from a DIV tag and I'm have a bit of trouble with the Regex. Right now I'm trying to remove the z-index attribute. It can look something like any of these:
z-index: 1000;
z-index: 0;
z-index: 75;
etc...
Here's what I'm using right now:
document.getElementById('right_column').innerHTML.replace(/z-index: [0-9]; /gi, "replaced"));
It replaces z-index: 0; just fine but I can't find the correct modifiers to make it work for 2, 3 or 4 digit z-indexes.
I was debugging my code looking for a loop. So in the process I added a confirm request and if the user clicked cancel I coded location.replace("Kill.html"). Problem was that the JAVASCRIPT continued to run until either it finished or I used the Task Manager to end the session. :( There3 was a small difference in browsers: Firefox put up the new screen while continuing to run the JAVASCRIPT while IE didn't put up the new screen until after the JAVASCRIPT was finished. I could tell the JAVASCRIPT was still running because the confirm messages kept popping up.

var ReplaceString = 'site'

I ran into a problem that I could not fix myself, I am trying to replace a string with another string, the replace lines look like this:
Code:
var word = document.getElementById("word").innerHTML; document.getElementById("word").innerHTML = wordd.replace(/B/g, '<span class="style106">B</span><span class="style107"> </span>'); It works just perfectly if left alone, but I need to replace every letter inside this string, adding those style and span tags around each and every letter. So if I add another line to this code, like this:

Is is possible to strip out some legacy <br> tags and replace them with </p><p>? A line break after the closing para would also be nice. And, can I target the asterisk and following space (see below) and delete it?
I've had a look at jQuery and managed to replace the br with p tags but they're the wrong way round i.e. open then close as it just manipulates the DOM not my string.
The current code/text is supplied from a database I don't have access to and the client doesn't have the time (nor the inclination I would suspect) to amend it.
Old existing code:
<p>blah blah blah<br>* blah blah blah<br>* blah blah blah<br>* blah blah blah</p>
New code wanted:
<p>blah blah blah</p>
<p>blah blah blah</p>
<p>blah blah blah</p>
<p>blah blah blah</p>
I'm looking for a very simple script to replace one div with another. I've found a few but they seem overly complicated with features I don't need. I simply want to be able to click on a div and for it to be replaced with another div previously hidden.

View 7 Replies View RelatedI've got a simple navigation system set up in a framed site:
navigation/top frame and a main body frame. Whenever you click on a
navigation button it passes the new location to this function:
gotoNewPage = function(loc) {
main.location.replace(loc);
// alert(loc);
}
which changes the page loaded in the main frame. This seems to work well
until I put a link in the page in the main frame, say:
<a href="#" onclick="top.gotoNewPage(Ƈ_7.htm')">Click me</a>
In IE the page changes to Ƈ.7.htm'.
In FF (and MZ) the page "flashes" but doesn't change.
If I uncomment the alert the page changes.
If I put the link in the nav frame the page changes in FF.
How can I get FF to behave in this instance?
I want to replace all occurences of this ),( in my string with a comma .....

I am creating a "Please wait..." page to show a friendly message to my
site users while the data is being loaded. I am using
location.replace() javascript function to do this.
The problem that I am facing is displaying the records that the
application has already processed on the wait page. Does anybody know
what can I do to pass data field value from the end page where the data
processing is going in background on to the wait page.
I found this in one of my old scripts but I can't remember what the -0 was used for. I remember it was a shortcut method but I can't remember for what. Does this ring a bell with anyone?

I have a question about manipulating a document. Suppose for example
that I had a table like this:
<table>
<tr id="row1">
<td>R1C1</td>
</tr>
<tr>
<td>R2C1</td>
</tr>
</table>
What I want to do is add an onclick event handler to row1 to insert a
row after row1. I can't seem to find a way to do it though. After
creating the new row node, I could try something like
document.getElementById("row1").parentNode.appendChild(newNode) but
that would add the new row to the bottom of the table. The
insertBefore() method is the right idea but I want to insert the new
row AFTER row1 and there doesn't seem to be an insertAfter() method.
I thought about navigating through the DOM tree to get the row after
row1 and then using insertBefore() but the table is generated
dynamically and there won't necessarily be a next row.
I was tring to write a function to make that took the letters that a
user is searching for and making the first occurrence of it bold in
the results (ignoring the case).
>From reading javascript books and looking at posts in this group, I
thought this would work. Perhaps I misunderstood what $1 is. But in
the results, I am getting a bold $1 with IE6.
How can I determine what the occurrence of the phrase is in the
correct case?
I realize I can write this parsing the string without regular
expressions but I thought this would be cleaner.
var match = new RegExp( escapeCharsForRegExp(typedLetters), "i");
if (match.test(text))
{
text = text.replace(match, '<b>' + '$1' + '</b>' );
}
Three questions
1)
I have a string function that works perfectly but according to W3C.org
web site is syntactically flawed because it contains the characters </
in sequence. So how am I supposed to write this function?
String.replace(/</g,'<');
2)
While I'm on the subject, anyone know why they implemented replace using
a slash delimiter instead of quotes? I know it's how it's done in Perl
but why is it done that way?
3)
One last regexp question:
is it possible to do something like this:
String.replace(/<(.*?)>(.*?)</$1>/ig,'<$1>$2</$1>');
This is just an example where a sub-match used in a regular expression
must sub-match again exactly as it did the first time later in the same
string. But I don't know how to do that in a regexp although it seems
like it should be possible.

Basically the php gives the javascript a list of movies located in my directory, I am able to successfully launch any movie not containing a "space." I changed the code a little bit to allow for a "text input" and manually typed the name of a movie with %20 instead of a space and it worked. So I would like to modify the above code to do this automatically without visibly changing the movie titles. I am not sure where I should change the code.
