I am having trouble removing spaces from a string. First I am converting the div to text(); to remove the tags (which works) and then I'm trying to remove the " " part of the string, but it won't work. Any Idea what I'm doing wrong.
newStr = $('#myDiv').text();
newStr = newStr.replace(/ /g, '');
$('#myText').val(newStr);
<html>
<div id = "myDiv"><p>remove space</p></div>
<input type = "text" id = "myText" />
</html>

When you use the text function, you're not getting HTML, but text: the entities have been changed to spaces.
var str = " a b ", // bunch of NBSPs
newStr = str.replace(/\s/g,'');
console.log(newStr)If you want to replace only the spaces coming from do the replacement before the conversion to text:
newStr = $($('#myDiv').html().replace(/ /g,'')).text();
.text()/textContent do not contain HTML entities (such as ), these are returned as literal characters. Here's a regular expression using the non-breaking space Unicode escape sequence:
var newStr = $('#myDiv').text().replace(/\u00A0/g, '');
$('#myText').val(newStr);

It is also possible to use a literal non-breaking space character instead of the escape sequence in the Regex, however I find the escape sequence more clear in this case. Nothing that a comment wouldn't solve, though.
It is also possible to use .html()/innerHTML to retrieve the HTML containing HTML entities, as in @Dystroy's answer.
Below is my original answer, where I've misinterpreted OP's use case. I'll leave it here in case anyone needs to remove from DOM elements' text content
[...] However, be aware that re-setting the .html()/innerHTML of an element means trashing out all of the listeners and data associated with it.
So here's a recursive solution that only alters the text content of text nodes, without reparsing HTML nor any side effects.
function removeNbsp($el) {
$el.contents().each(function() {
if (this.nodeType === 3) {
this.nodeValue = this.nodeValue.replace(/\u00A0/g, '');
} else {
removeNbsp( $(this) );
}
});
}
removeNbsp( $('#myDiv') );
