从 textarea 中删除换行符和空格

Question

<textarea rows='5' cols='50' id='content'></textarea>
<input type='button' value='Extract Text' onclick='someFunction()'/>

Assume these two html elements. My problem is the following:

Let's say that the user enters into the textarea field something like this, exactly as typed. With all line breaks and spaces. (And yes, this is Python :P)

if (...):  
   print "Hello everyone!"
else:
   print "Dudes help me out!"

My objective is to make a JavaScript function which removes all the spaces and line breaks (typed with 'Enter') and returns a space-less string. Something like "ThisIsASampleText". I've used document.getElementById('content').value and myString.replace(/\\s+/g, '') to remove spaces. Can't make it work. Any ideas?

Best Regards

Here's a live demo of how to use the regex you described to remove all whitespace in the text from your textarea:

 function someFunction() { var output = document.getElementById("content").value; output = output.replace(/\\s/g, "") document.getElementById("output").innerHTML = output; }

 <textarea rows='5' cols='50' id='content'></textarea> <input type='button' value='Extract Text' onclick='someFunction()'/> <div id="output"></div>
