String Replace And Reg Exp In Javascript

Mar 31, 2006

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?

Replace A String With Another String, The Replace Lines Look Like This?

Aug 19, 2010

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:

String.replace

Apr 4, 2007

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>' );
}

String.replace(/</g,'&lt;');

Jul 20, 2005

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,'&lt;');

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,'&lt;$1&gt;$2&lt;/$1&gt;');
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.

String().replace() Usage...

Can someone help my syntax?

var z=myForm.myInputTag.value.string().replace(" ","-");

I would expect the above to allow z to take the value of an input tag

Replace Whitespace Characters In String

Oct 12, 2005

I have a JavaScript string. I want to replace all consecutive
occurrences of whitespace characters like spaces, tabs, newlines, and
form feeds with another string.

For example, say I have a string consisting of:

-- 3 spaces
-- The characters "hello"
-- 2 newline (
) characters
-- The characters "goodbye"
-- 5 spaces

After applying some sort of regular expression to replace consecutive
occurrences of whitespace chars with the string "X", the string should
consist of the following:

-- The character "X"
-- The characters "hello"
-- The character "X"
-- The characters "goodbye"
-- The character "X"

How could I do this using regular expressions? I'm quite familiar with
JavaScript but don't know anything about regular expressions or using
them in JavaScript, so please show me step-by-step how it's done.

JQuery :: Possible To Replace String Characters?

Aug 4, 2009

I am running a search on my web site which uses jQuery to take the search terms and build up a URL based on them. For example, if someone searches for "chair" my URL will be appended with /chair/. However, if someone searches for something which is two words, for example "chair covers" I need the space in between to be replaced by a "+" sign so the URL will now be appended with /chair+covers/ I'm not sure if it is possible to string replace in jQuery?

Here is my current code:
function sendSearchInput(whichelement,hiddeninput,formid) {
hval = $("#"+hiddeninput).val();
$("#"+formid).submit(function() {
if ($("input:#"+whichelement).val() != hval) {
var searchval = $("#"+whichelement).val().toLowerCase();
$("#"+formid).attr("action","retail/search/"+searchval+"/");
return true;
}
$("input:#"+whichelement).focus();
return false;
});}

This will basically check that the form is not the default value (specified in the hidden field "hval") and then change the search term to lowercase and append the URK using "attr". I have tried a couple of methods including
var test = searchval.text().replace(' ','+');
And then trying to alert "test" to check it but the function just simply doesn't work.

Replace Markup Pattern Within A String?

Feb 22, 2010

Im trying to find if a particular html markup pattern (<ROD> ... </ROD>) within a string and if its found then replace it with another string.eg."This is my string and it might <ROD>PartNumber123</ROD> contain HTML markup"So in this case I want to replace "<ROD>PartNumber123</ROD>" with {0}. If there is no <ROD>...</ROD> then dont do anything.Im sure im doing this the wrong way, maybe a regular expression would be best.Although this works its not very clean and I just cant find the correct solution.

function parseData(data){
var r1 = data.indexOf("<ROD>",0);
var r2 = data.indexOf("</ROD>",0);

Adding Tags Using String.replace()

Oct 9, 2003

When trying to emulate php's nl2br() function in javascript, I ran into something quite disturbing.

Code:
cms.t.value = cms.t.value.replace(/

Using this piece of code, I was really surprised that the newlines weren't preceded by <br />, but by <br>. I really don't understand why that would happen. Why can't I decide my own replacement string? .
