The input output by echo cannot call the onclick event. & lt; SCRIPT & nbsp; language = JavaScript & nbsp; type = text/JavaScript & gt; function & nbsp; CheckAll (form) & nbsp; {for & nbsp; (var & nbsp; I = 0; input from I echo cannot be used to call the onclick event.

Function CheckAll (form ){
For (var I = 0; I Var e = form. elements [I];
If (e. name! = 'Chkall') e. checked = form. chkall. checked;
}
}

SCRIPT
Require_once 'sqlhelper. class. php ';
$ SqlHelper = new SqlHelper ();
$ SQL = "select * from user1 ";
$ Res = $ SqlHelper-> execute_dql ($ SQL );
$ Fields = mysql_num_fields ($ res );
$ Rows = mysql_num_rows ($ res );
Echo" ";
Echo" ";
For ($ I = 0; $ I <$ fields; $ I ++ ){
$ Fieldname = mysql_field_name ($ res, $ I );
Echo"$ Fieldname";
}
Echo"";
$ Num = 1;
While ($ row = mysql_fetch_row ($ res )){
Echo"";
Echo" ";
For ($ I = 0; $ I <$ fields; $ I ++ ){
Echo"$ Row [$ I]";
}
Echo"";
$ Num ++;
}
Echo"";
?>

Why does onclick = CheckAll (this. form) call js and share it with function? CheckAll (form )? {? (Var? I = 0;... 'data-pics = ''>
------ Solution --------------------
In addition, echo" "; Does not comply with php's conventions

First, you need firefox and firebug plug-ins.

Then, if a JS error occurs in the "control" column, an error is reported, where is the problem?
