Replace All Newlines With <br> Tags

Jul 23, 2005

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?

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(/
/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? .

Character Codes For Newlines In Textareas

Aug 25, 2006

I have some Javascript code that reads and sometimes sets the content of
a textarea. I want this to be reasonably browser and platform independent. My question is, what characters should I expect to find at the end of a line? I suspect that I need to cope with either "" or""; can someone confirm?

Setting the content is more of a challenge. I don't want to have nasty browser detection to select what to use for newlines. Is there one newline pattern that is safe for all browsers?

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

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:

Minimized The Use Of <img> Tags?

Nov 30, 2009

I have some extensive animation going on in this script. I have all the behavior I want out of this script. A 3D carousel interface, each window in the carousel is a separate UI window. It uses active scrolling for navs and content...like (iphone).The problem is that I have optimized to my best and still cant gain any performance out of IE. It runs pretty fast in FF, and in Safari. I have reversed loops, I have vared all my Math, I have stripped equations, could do more I guess, and I have made attempts at preventing even bubbling. I have minimized the use of <img> tags as well. I have even cached most methods and use a constructor method to create new HTML elements.At this point I am starting to feel like I am getting into techniques and areas of JS I just don't understand well.Here is example of a method I would like to optimize:

this.anim = function () {
var s = Math.sin(s3D.A * .01);
var c = Math.cos(s3D.A * .01);[code]....

Getting Text From Between Two Tags?

Aug 23, 2004

what I'm trying to do is get text from between two tags, just like the title says. Now I know I can get that through the innerHTML property, but its just that, I don't want HTML, I want plain text. Consider the following example.

<span id="p-5641">
This is <strong>strong</strong> & you should really put <em>emphasis</em> on that <a href="#">anchor</a>.<br>Line broken
</span>

Now, what I want is, to get the text from between these span tags. That can be done by refering the ID of the span & innerHTML but that would give HTML & I want to strip off the HTML from it, so that I'm left with plain text, like

This is strong & you should really put emphasis on that anchor.
Line broken
with <br> & <p> tags preserved.
