parameter function in jquery -


i want make function parameter. working below code not working. can tell me doing wrong.

<head> <script type="text/javascript" src="jquery-1.7.2.js"></script> <script type="text/javascript"> $(function hide(fn){ $(fn).click(function(){ $('div').hide() }) }) </script> <style> div { width:500px; height:500px; background:#ff0000; } </style> </head> <body> <button onclick="hide(this)">click hide</button> <a href="#">click</a> <button>click</button> <div></div> </body>

one important thing: should write unobtrusive javascript, considered best practice. it, can maintain separation of content code. thus, first step remove onclick handler on <button> element.

i'm assuming want click button says "click hide" hide <div>. okay, let's skeleton code out <script>:

$(document).ready(function() { $(<button>).click(function() { $(<div>).hide(); }); });

but need somehow link click handler button, , link hide function actual div. here's easiest way this: give <button> , <div> ids. let's say...

<button id="hide-button">...</button> <div id="hide-div">...</div>

now, need make few modifications our skeleton code:

$("#hide-button").click(function() { $("#hide-div").hide(); });

here's simple code does. when dom loads, nameless function (you can't name functions define on fly*) invoked document's ready event. nameless function attaches click handler #hide-button button, when click button, anonymous function invoked. function calls hide, jquery magic works in browsers, on #hide-div div hide it.

*well, can, if define them first , pass them. this:

var fn = function() {...}; $(document).ready(fn);

edit

since asker not want use ids or classes, here's alternative solution:

<script> function hide() { $('div').hide(); } </script> ... <button onclick="hide()">click hide</button> <div></div>

be careful not place function hide() within jquery's document-ready idiom. doing deny access hide() because of scoping.

php - Get uncommon values from two or more arrays -

is there function in php give array of uncommon values 2 or more arrays? for example: $array1 = array( "green", "red", "blue"); $array2 = array( "green", "yellow", "red"); .... $result = function_needed($array1, $array2,...); print_r($result); should give output: array("blue", "yellow", ...); use array_diff , array_merge : $result = array_merge(array_diff($array1, $array2), array_diff($array2, $array1)); here's demo. for multiple arrays, combine callback , array_reduce : function unique(&$a, $b) { return $a ? array_merge(array_diff($a, $b), array_diff($b, $a)) : $b; } $arrays = array( array('green', 'red', 'blue'), array('green', 'yellow', 'red') ); $result = array_reduce($arrays, 'unique'); and here's demo of that.

Adding duplicate array rows in Php -

i create function in php adds rows of array shared column value. so input. $test = array( array("c", 5, 6), array("c", 2, 3), array("test", 5, 6) ); and output. $testduplicatefree = array( array("c", 7, 9), array("test", 5, 6) ) ); i'm thinking function combine_duplicates($array,$col){ ... ... return $duplicatefreearray; } where $col duplicate free array. so, in case, combine_duplicates($test,0); would me desired output. this. <?php function combine_duplicates($array,$col) { $index = array(); foreach ($array $row) { $key = $row[$col]; if (!isset($index[$key])) { $index[$key] = $row; } else { ($i = 0; $i < count($row); ++$i) { if ($i != $col) { $index[$key][$i] += $row[$i]; } } } } return array_values($index); } $array = array( array("c", 5, 6), array("c", 2, 3), array("test", 5, 6) ); print_r(combine_duplicates($array, 0)); try here: http://codepad.org/mdhesqhi
