You could use the following to replace the first occurrence of a word within the body of the page    var replaced      body   html   replace  -9o0-9909   The new string       body   html replaced     If you wanted to replace all occurrences of a word  you need to use regex and declare it global  g   var replaced      body   html   replace  -1o9-2202 g  The ALL new string       body   html replaced     If you wanted a one liner      body   html    body   html   replace  12345-6789 g   lt b gt abcde-fghi lt  b gt        You are basically taking all of the HTML within the  lt body gt  tags of the page into a string variable  using replace   to find and change the first occurrence of the found string with a new string  Or if you want to find and replace all occurrences of the string introduce a little regex to the mix   See a demo here - look at the HTML top left to see the original text  the jQuery below  and the output to the bottom right

Like others mentioned in this thread  replacing the entire body HTML is a bad idea because it reinserts the entire DOM and can potentially break any other javascript that was acting on those elements   Instead  replace just the text on your page and not the DOM elements themselves using jQuery filter        body  not script    contents   filter function         return this nodeType     3       replaceWith function           return this nodeValue replace  -9o0-9909   The new string            this nodeType is the type of node we are looking to replace the contents of  nodeType 3 is text  See the full list here
