How is a non-breaking space represented in a JavaScript string

Question

This apparently is not working   X    td text    if  X      amp nbsp      X           Is there something about a non-breaking space or the ampersand that JavaScript doesn t like

Remember that  text   strips out markup  thus I don t believe you re going to find  amp nbsp  in a non-markup result    Made in to an answer      var p       lt p gt    html   amp nbsp     if  p text      String fromCharCode 160   amp  amp  p text        xA0       alert  Character 160      Shows an alert  as the ASCII equivalent of the markup is returned instead

amp nbsp  is a HTML entity  When doing  text    all HTML entities are decoded to their character values   Instead of comparing using the entity  compare using the actual raw character   var x   td text    if  x      xa0        Non-breakable space is char 0xa0  160 dec    x           Or you can also create the character from the character code manually it in its Javascript escaped form   var x   td text    if  x    String fromCharCode 160        Non-breakable space is char 160   x           More information about String fromCharCode is available here      fromCharCode - MDC Doc Center   More information about character codes for different charsets are available here      Windows-1252 Charset   UTF-8 Charset

That entity is converted to the char it represents when the browser renders the page  JS  jQuery  reads the rendered page  thus it will not encounter such a text sequence  The only way it could encounter such a thing is if you re double encoding entities

The jQuery docs for text   says     Due to variations in the HTML parsers   in different browsers  the text   returned may vary in newlines and   other white space    I d use  td html   instead
