javascript - Replacing string in innerHTML -

-

so, simple thing i'm trying accomplish (javascript), it's taking me ages , still not work. i'm trying replace words (that within pre tag). example, word "static" should replaced "<span class="keyword">static</span>". i'm using xhtml strict.

my approach this:

for (var j = 0; j < keywords.length; j++)     {         codeblock.innerhtml = codeblock.innerhtml.replace(new regexp(keywords[j], "g"), "<span class=\"keyword\">" + keywords[j] + "</span>");     }

codeblock pre element, keywords array contains words replace.

i've tried many ways, i'm stuck error messages these.

firefox:

[exception... "an invalid or illegal string specified" code: "12" nsresult: "0x8053000c (ns_error_dom_syntax_err)" location: "file:///c:/.../scripts.js line: 33"]

chrome:

error: invalid_state_err: dom exception 11

i'm guessing has html tags (i've tried using %lt; , %gt; instead), because know work:

codeblock.innerhtml = codeblock.innerhtml.replace(new regexp(keywords[j], "g"), "test");

thanks time, jacco

you need wrap code in cdata

<script type="text/javascript">  //<![cdata[ (var j = 0; j < keywords.length; j++)     {         codeblock.innerhtml = codeblock.innerhtml.replace(new regexp(keywords[j], "g"), "<span class=\"keyword\">" + keywords[j] + "</span>");     }  //]]> </script>

properly using css , javascript in xhtml documents

this way code not parsed xhtml validity.

your current code works fine me @ http://jsfiddle.net/gaby/y92ae/
