javascript - Functions with appropriate parameters -

-

hello have more of question. working functions , events have far..

   <!doctype html public "-//w3c//dtd xhtml 1.0 strict//en"    "http://www.w3.org/tr/xhtml1/dtd/xhtml1-strict.dtd">    <html xmlns="http://www.w3.org/1999/xhtml">    <head>    <title>personal information</title>    <meta http-equiv="content-type" content="text/html; charset=utf-8" />    <link rel="stylesheet" href="js_styles.css" type="text/css" />    <script type="text/javascript">    //<![cdata[    function printperonalinfo( "name,age,hobbies,favorite movies") {    document.write("<p>" + name +"</p>");    document.write("<p>" + age +"</p>");    document.write("<p>" + hobbies + "</p>");    document.write("<p>" + favorite video + "</p>");    }    //]]>    </script>    </head>    <body>    <script type="text/javascript">     / * <![cdata[ */    printperonalinfo( "age,age,hobbies,favorite movies")    var return_value = return_message();    document.write(return_value);    /*]]> */     </script>    </body>    </html>

now question have know doing wrong cause not showing on web page. suppose read name,age, hobbies, favorite movies. repeat have in head body instead of word name put name in there or use if or else(but pretty sure buttons). know can use array don't know if work or not.

you have several mistakes..

function printperonalinfo( "name,age,hobbies,favorite movies") { /*                         ^ no quotes here, ^ invalid variable name */ // should be: function printperonalinfo(name, age, hobbies, favorite_movies) {    document.write("<p>" + name +"</p>");    document.write("<p>" + age +"</p>");    document.write("<p>" + hobbies + "</p>");    document.write("<p>" + favorite video + "</p>");    /*                     ^ undefined variable, isn't defined in function */    // should be: document.write("<p>" + favorite_movies + "</p>"); }

...

printperonalinfo( "age,age,hobbies,favorite movies"); /*                ^ incorrect passing of data */ // should be: printperonalinfo("name", "age", "hobbies", "favorite movies");

you should aware function name misspells "personal" "peronal".

update: in 2nd <script> block, have incorrect comment-block tag: / * should not have space. correct: /*

(or else how bar method keep myclass variables straight on per instance basis?) now (2) question i'm after. since inner foo method doesn't use in myclass enclosure natural qustion is: javascript smart enough not keep myclass enclosure in memory use of foo? this depend entirely on implementation not language. naive implementations keep far more around others. answer true e.g. v8 (chrome's js engine) may not true spider...

example preg_replace('/\{[a-za-z.,\(\)0-9]+\}/', 'replaced', 'lorem ipsum dolor sit {tag1({tag2()})}, consectetur adipiscing elit.'); the result: lorem ipsum dolor sit {tag1(replaced)}, consectetur adipiscing elit. question as can see "tag2" has been replaced, want replace "tag1" know how can this? (in cases might this: {tag1({tag2({tag3()})})}) , on.) btw using preg_replace_callback, easier show preg_replace here site can test code: http://www.spaweditor.com/scripts/regex/index.php you need add curly braces character set. here's pattern used: /\{[a-za-z.,\(\)\{\}0-9]+\}/ and here result: "lorem ipsum dolor sit replaced, consectetur adipiscing elit."
