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? .
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>
<body>
[code]....
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 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 am using this script which is nearly working correctly, but not quite!
When a user selects some text from the web-page and copies it,the script is supposed to pick up the current web-page url and create a resource box or credit line that is added to the selected text when the data is pasted.
You will see that the meta keywords are used (randomly) as the anchor text and this should be wrapped with the href= tags in order to create a link. Thats the bit that is not workink, but I can not see why.
Here is the complete script.
function init(){
// Options:
var useMetaKeyword = true; // Otherwise, page title
var minLength = 40; // Min selection chars

I have wrote some jQuery thats adds a class to any <a> tag that contains an external link. That way an icon can be applied to the <a> using CSS!
Code JavaScript:
$("#contentPg > p > a[href^='http://']").addClass('icon').addClass('wwwDoc').attr('rel','external');
However, I want to try and modify this script so that it only adds the class if the <a> tag is directly after a <p>, however I am not sure how to achieve this? The reason I wish to achieve this is so that Icons are not applied when the link is in the middle of a line of text, but only when the link is on a line of its own!
I'd like to know how to add break tags "<br>" inbetween entry's in an input form, an example is if the word "yada yada" was entered you would wind up with y<br>a<br>d<br>a<br> y<br>a<br>d<br>a
I would like to able to add the break tags with a button onClick. I have no idea where to start ...
How can I use jQuery to add a css class to the first level of <li> tags under a <ul> tag? I have this so far:
$("ul.menu li:first").addClass("myClass");
But this only adds the "myClass" to the first <li>, I'd like the set of <li> tags directly underneath to have the same css class. I have a menu structure and it's only the first set
of <li> tags I'm interested in.

I am putting the finishing touches to a custom written (pHp) article editor to allow users to publish content on a website.I have basically finished the project, and I am putting the finishing touches in with jquery widgets, such as a word counter. I would also like people to be able to highlight a section of text, then have some custom tags wrap the text (much like on this forum when you highlight a word in the message box and hit the wrap button).I would like my own custom tags to be used, such as <span class='someclass'>some entered text</span> rather than predefined ones.
View 9 Replies View RelatedI 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?

I realize I can write this parsing the string without regular
expressions but I thought this would be cleaner.

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.

The problem is with identifying the � as opposed to '.
Is there a possibility to do a string replace in javascript without regular experessions. It feels like using a hammer to crash an egg.
