javascript - display or read colspan value -


i created table contain colspan , rowspan. or read these colspan , rowspan value. i'm doing because want use xml generation. need value. play around code test:

<!doctype html> <html> <head> <script> function displayresult() { document.getelementbyid("myheader1").colspan="2"; } function displaycolspan() { var te; document.getelementbyid("myheader1").colspan=te; alert(te); } </script> </head> <body>  <table border="1">   <tr>     <th id="myheader1">month</th>     <th id="myheader2">savings</th>   </tr>   <tr>     <td>january</td>     <td>$100.00</td>   </tr>   <tr>     <td>february</td>     <td>$10.00</td>   </tr>   <tr>     <td>march</td>     <td>$80.00</td>   </tr> </table> <br>   <button type="button" onclick="displayresult()">change colspan first cell</button> <button type="button" onclick="displaycolspan()">test</button> </body> </html>

could me? thanks!

there's bit of confusion code.

this:

document.getelementbyid("myheader1").colspan=te;

changes colspan value of myheader1 var te, undefined. instead should do:

te = document.getelementbyid("myheader1").colspan

now te colspan value of myheader1.

if want value, 'month':

te = document.getelementbyid("myheader1").innerhtml

now te has value of 'month'!

hope helps!

php - Accessing static methods using newly created $obj or using class Name -

see class definition below: i using 5.3.9 version of php class a{ static function ab(){ echo "static function ab<br>"; } public function xy(){ echo "public function xy<br>"; } } $obj = new a(); $obj->ab(); a::ab(); both functions call give same output without error static function ab static function ab how possible static method can called class object? because static method calls using class name only?! now difference between accessing these 2 ways call static method ? referring php.net website declaring class properties or methods static makes them accessible without needing instantiation of class. property declared static can not accessed instantiated class object (though static method can). a big difference is because static methods callable without instance of object created, pseudo-variable $this not available inside method declared static. refer page php.net/manual/en/
