in the code below I an trying to replace a string with another string, then write the new string in JavaScript tags. But the result is not what I wanted: first the original string was not replaced, second plain text is shown, instead of popping up an alert. Is there a way I can replace the string and execute the command?
Code:
<html>

When trying to emulate php's nl2br() function in javascript, I ran into something quite disturbing.
Code:
cms.t.value = cms.t.value.replace(/
/gi, '<br />
');
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? .
Here is my code:
<script type="text/javascript">
var str="Welcome to Microsoft! Microsoft Microsoft";
var stringToBeFound = 'Microsoft'
var ReplaceString = 'site'
document.write(str.replace(stringToBeFound , ReplaceString ));
</script>
My problem is im trying to use string.replace that is not case sensitive and replace every string found. I could use regular expression with it but my stringToBeFound is a dynamic variable im getting it from my database
I have a function defined in my document's <head> section which adds a <script> tag to a specified <div> tag. The added <script> has a src="" attribute pointing to a PHP file, which dynamically returns JavaScript. In Safari, the src file isn't downloaded. Neither is any code contained within the new script tag [such as alert()]. In IE(6) and Firefox, this works as expected. Here's my code:

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:

PHP has a function called nl2br() which takes all the newlines in a
string and turns them into break tags <br>. I need to do the same in
javascript. Is this about right? I'm not sure how one is supposed to
reference invisible characters in Javascript strings. I took an example
on the web and tried to modify it to my uses.
function nl2br_js(myString) {
var regX = /
/gi ;
s = new String(myString);
s = s.replace(regX, "<br />
");
return s;
}
After looking around quite a bit using Google, I still couldn't find
out what the gi in the above example is for. What is it?

I have my website getting a value as a result of an ajax call. After that, I would like to insert that result (a string) into a tag. However, I would like to insert that result in a way that (1) it must have opacity = 0, then (2) it will slideDown() so the whole content list being pushed down using animation, and finally (3) change opacity = 1. Imagine this is just like a Facebook message list insert process The way I am planning to do this is to return the result string from ajax to opacity=0 first. However, I don't know how to use jQuery to select a tag from within a string. I know jQuery only select from the DOM. So how to do this?
View 2 Replies View RelatedI was tring to write a function to make that took the letters that a

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.

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?
