Some alternative php js Code

1. Batch selection and Deletion

Use this. Form

<script type="text/javascript">function CheckAll(form) { for (var i=0;i<form.elements.length;i++) { var e = form.elements[i]; if (e.name != 'chkall') e.checked = form.chkall.checked; } } </script>

Name is defined as check []
<Input type = "checkbox" name = "check []" value = <? PHP echo $ data [0];?>

Use in

$userId = implode(',',$_POST['check']);//alert(print_r($userId));mysql_query("DELETE FROM `user` WHERE `id` IN ($userId)");

2. Use the editor

<script charset="utf-8" src="../kindeditor/kindeditor.js"></script><script>KE.show({id : 'content',afterCreate : function(id) {KE.util.focus(id);}});</script>

3. Write special characters in the image database.

$ Info = addslashes ($ _ post ['info']);
$ Query = "insert into live values (null, '$ time',' $ info', 0 )";

Or use mysql_escape_string, which is not recommended for PHP.

4,

Prevent table content Overflow

     <td>           <div  style="width:100px;             overflow:hidden;             text-overflow:ellipsis;                 white-space:nowrap; height: 20px; ">         <?php echo $data[5];?>        </div>        </td>

5 IFRAME nesting at any position

<SCRIPT type = "text/JavaScript">
If (parent! = This)
Parent. Location. Reload ();
</SCRIPT>

<Div onclick = "alert ('A')" id = "logindiv" style = "position: fixed; left: 300; top: 200; width: 400; Height: 300; overflow: hidden; ">
<Div style = "width: pixel PX; Height: 300px; overflow: hidden;" onclick = "alert ('A')">
<IFRAME Style = "margin-top:-400px; margin-left:-2px; margin-Right:-5px; width: 400px; Height: 700px; "id =" datamain "src =" http: // localhost/joomla2.5/index. PHP/2012-11-15-10-25-42 "scrolling = NO> </iframe>
</Div>

5. Convert JS hexadecimal to hexadecimal

Function oxto (Num) {var result = 0; // output result var flg = false; var k = 1; // base for (VAR I = num. length; I> 0; I --) {Switch (Num [I-1]) {Case "1": Case "2": Case "3": Case "4 ": case "5": Case "6": Case "7": Case "8": Case "9": Result + = num [I-1] * k; break; case "A": Case "A": Result + = 10 * k; break; Case "B": Case "B": Result + = 11 * k; break; case "C": Case "C": Result + = 12 * k; break; Case "D": Case "D": Result + = 13 * k; break; case "E": Case "E": Result + = 14 * k; break; Case "F": Case "F": Result + = 15 * k; break; case "X": Case "X": Alert ("Result:" + result); break; default: flg = true; break;} k = K * 16; if (flg) {break;} return result ;}

6. Verify the form and obtain the focus:

function checksubmit(){var check = true;$("#requiredata input").each(function(){if($(this).val() == ""){$(this).focus();check = false;return false;}});}
