shaunmckinnon Posted July 3, 2008 Share Posted July 3, 2008 explain further. do you mean you're trying to call the onClick event in PHP? Link to comment https://forums.phpfreaks.com/topic/113077-parse-js-variable-to-attribute/#findComment-580891 Share on other sites More sharing options...

Each will be the id of the checkboxes.A want to check those 2 checkboxes.I use the variables into document.getElementById('n1').checked=true which the variable is the n1 but it doesnt recognize it as variable!

shaunmckinnon Posted July 3, 2008 Share Posted July 3, 2008 I think you're trying to pass PHP variables to the javascript function. If that's the case, you may be approaching it wrong. ie: <html> <head> <script> function check(n1,n2) { document.getElementById('n1').checked=true; document.getElementById('n2').checked=true; } <script> </head> <body> <form> <input type="radio" id="n1" name="n1"> <input type="radio" id="n2" name="n2"> <input type="button" id="checker" name="checker" onClick="check('n1', n2');"> </form> </body> </html> [code] [/code] Link to comment https://forums.phpfreaks.com/topic/113077-parse-js-variable-to-attribute/#findComment-580959 Share on other sites More sharing options...
shaunmckinnon Posted July 3, 2008 Share Posted July 3, 2008 that should work. if you're trying to pass PHP variables, you need to echo the variables in the javascript code. probably easier to <? $variable_1 = "unchecked"; $variable_2 = "checked"; echo '<input type="radio" id="" name="" value="'.$variable_1.'">'; ?> i would just block what i need to do in a small php block. still don't quite know what you're looking to do, but hopefully one of these code blocks can help decipher some hassle for you.

aliento Posted July 4, 2008 Author Share Posted July 4, 2008 Ok i will make it simple . lets say i got this js function function check(n1) { n1 = "c" + n1; document.getElementById('n1').checked=true; } or function check() { chu = "checke"; document.getElementById('something').chud=true; } // the chu is the variable. and with the d makes checked? The question is how the javascript recognize the variable. I know php and html, i can read javascript and 'write' but i dont know the basics.

aliento Posted July 4, 2008 Author Share Posted July 4, 2008 For the archive and better understudying i write the code below : php file : for($i=0;$i<count($fields);$i++) echo '<td>'.$fields[$i].'<input type="checkbox" name="field_check[]" id="c'.$i.'" /></td>'; //and for the onclick : for($iii=0;$iii<count($fields);$iii++) echo '<td onclick="check(\'c'.$iii.'\',\'c'.$ii.'\')">'; the javascript is : function check(n1,n2) { document.getElementById('n1').checked=true; document.getElementById('n2').checked=true; } I cant find any mistake. Can you? Link to comment https://forums.phpfreaks.com/topic/113077-parse-js-variable-to-attribute/#findComment-581662 Share on other sites More sharing options...
adam84 Posted July 10, 2008 Share Posted July 10, 2008 Try this function check(n1,n2){ document.getElementById(n1).checked=true; document.getElementById(n2).checked=true; } Both n1 and n2 are variables, so when they are inside quotes, you are not using the variable, but rather just the string or whatever 'n1' and 'n2'.
