php 。 indivual event Cancel Can Actual combat binding transfer conduct repeat

1.jquery事件可以绑定N个，如果不进行取消就会重复调用绑定的事件。深感体会，搞了两小时终于发现其中奥妙。
以下代码不能单独运行的。需要 bootstrap和jquery
[javascript] /**
* 用于显示对话框消息框
* 参数 title 消息标题
* 参数 content 消息内容
* 参数 buttomTitle 处理消息的按钮自定义的，比如确认删除
* 参数 fun 自定义按钮click事件
* 参数 passOnData 传递到自定义fun里的参数
*/
function show_Msg (title,content,buttomTitle,fun,passOnData) {
    $("#msg #myModalLabel").html(title);
    $("#msg .modal-body").html(content);
    $('#msg #msg_c').html(buttomTitle).click(function(){
        fun(passOnData);//调用自定义的函数,以及传递自定义的数据
        $('#msg').modal('hide');//点击完就把窗口隐藏了
        $(this).unbind('click');//如果不取消事件，那么将重复调用。。
    });;
    $('#msg').modal('show');
}

/**
* 用于显示对话框消息框
* 参数 title 消息标题
* 参数 content 消息内容
* 参数 buttomTitle 处理消息的按钮自定义的，比如确认删除
* 参数 fun 自定义按钮click事件
* 参数 passOnData 传递到自定义fun里的参数
*/
function show_Msg (title,content,buttomTitle,fun,passOnData) {
$("#msg #myModalLabel").html(title);
$("#msg .modal-body").html(content);
$('#msg #msg_c').html(buttomTitle).click(function(){
  fun(passOnData);//调用自定义的函数,以及传递自定义的数据
  $('#msg').modal('hide');//点击完就把窗口隐藏了
  $(this).unbind('click');//如果不取消事件，那么将重复调用。。
});;
$('#msg').modal('show');
}html消息框模板
[html]

调用例程
[javascript] show_Msg('标题要长长长长的','这里可以写html比如加粗的的字体噢','删除',function(e){
alert(e);
},'这里是点击删除后我传递过去的数据');

show_Msg('标题要长长长长的','这里可以写html比如加粗的的字体噢','删除',function(e){
alert(e);
},'这里是点击删除后我传递过去的数据');

[javascript] function admin_content_del (id) {
    var data=listData[id];
    show_Msg('确认删除',data.content,'确认删除',function(delId){
        $.ajax({
          url: 'http://localhost/l/index.php',
          type: 'get',
          dataType: 'json',
          data: {
            m: 'admin',
            a: 'delcontent',
            id: delId
          },
          complete: function(xhr, textStatus) {
            //called when complete
          },
          success: function(data, textStatus, xhr) {
            if(data.state='ok'){
                admin_content(1);
                show_Msg_success('删除成功');

            }else{
                show_Msg_success('删除失败');
            }
          },
          error: function(xhr, textStatus, errorThrown) {
            //called when there is an error
          }
        });

    },data.id);
}

2.setTimeout延迟执行事件，这消息过真不错，挺常用的，但是这清空消息的方式，简单粗暴。

[javascript] /**
* 用于显示顶部消息。显示的消息3秒后自动销毁。
* 参数 content 消息内容
* 参数 face 消息的样式，真，为成功绿色的；假，为错误红色的
*/
function show_Msg_success(content,face){
    if (face==null) {
        face=true;
    }

    face = face?'success':'error';

    strTag='

'+content+'

';

    $(strTag).prependTo('#main');

    setTimeout(function(){
        $(".alert").alert('close');
    },3000);
}

/**
* 用于显示顶部消息。显示的消息3秒后自动销毁。
* 参数 content 消息内容
* 参数 face 消息的样式，真，为成功绿色的；假，为错误红色的
*/
function show_Msg_success(content,face){
if (face==null) {
face=true;
}

face = face?'success':'error';

strTag='

'+content+'

$(strTag).prependTo('#main');

setTimeout(function(){
$(".alert").alert('close');
},3000);
}

3.checkbox选中还是纯dom操作好. jquery的arrt()方法坑爹
checkbox.attr('checked',$(this).get()[0].checked);

选中复选框，但是第一次有效，第二次也有效，第三次以后，离奇失效了。问题不名真相。
[javascript] function click_tr() {
    var checkbox = $("#mainData tr input");

    checkbox.eq(0).click(function() {
        //checkbox.attr('checked',$(this).get()[0].checked);

        bool = $(this).get()[0].checked;

        for (var i = 1; i             checkbox[i].checked = bool;
        };

    });

    $("#mainData tr").each(function(index) {
        $(this).click(function() {

            if (index == 0) {

            } else {
                var val = checkbox.eq(index);
                    val = val.get()[0];
                var bool = val.checked;

                //alert(index);
                if (bool) {
                    val.checked = false;
                } else {
                    val.checked = true;
                }
            }

        });

    });

function click_tr() {
var checkbox = $("#mainData tr input");

checkbox.eq(0).click(function() {
//checkbox.attr('checked',$(this).get()[0].checked);

bool = $(this).get()[0].checked;

for (var i = 1; i checkbox[i].checked = bool;
};

});

$("#mainData tr").each(function(index) {
$(this).click(function() {

if (index == 0) {

   } else {
    var val = checkbox.eq(index);
        val = val.get()[0];
    var bool = val.checked;

    //alert(index);
    if (bool) {
     val.checked = false;
    } else {
     val.checked = true;
    }
   }

  });

});进行探究一番写了一测试代码，但是依然无果，不明真相的全选不了。
[html]

全选
取消选中

$("#quxiao").click(function(){
$("#myform input").attr('checked',false);
});
});

4.说了这么多都没上效果图呢.

5.标题说是php实战，怎么前面帖的都是php代码。。下面帖出处理批量删除的php代码
[php] /**
* 用于批量删除留言
*/
function batchDelContent(){
    $json['state']="no";

    $data=Array();

    $arr=$_POST['delcontent'];
    if (count($arr)>0) {
        $json['state']="ok";
    }

    foreach ($arr as $value) {

        $result=$this->db
             ->where("id=".$value)
             ->table("data")
             ->delete();

        if ($result) {
            $arr_data['state']="ok";
        }else{
            $arr_data['state']="no";
        }
        $arr_data['id']=$value;

        $data[]=$arr_data;
    }

    $json['data']=$data;
    echo json_encode($json);
}

  /**
  * 用于批量删除留言
  */
  function batchDelContent(){
   $json['state']="no";

$data=Array();

   $arr=$_POST['delcontent'];
   if (count($arr)>0) {
    $json['state']="ok";
   }

foreach ($arr as $value) {

    $result=$this->db
      ->where("id=".$value)
      ->table("data")
      ->delete();

    if ($result) {
     $arr_data['state']="ok";
    }else{
     $arr_data['state']="no";
    }
    $arr_data['id']=$value;

$data[]=$arr_data;
}

   $json['data']=$data;
   echo json_encode($json);
  }今天写的php代码也就这么点了。。大部分都是javascript

我把admin.js帖出来给大家观赏一下。
