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]
show_Msg('The title should be long', 'You can write HTML here such as bold font', 'Delete', function(e){
alert(e);
},'Here is the data I passed after clicking delete');
[javascript] function admin_content_del (id) {
var data=listData[id];
Show_Msg('Confirm deletion',data.content,'Confirm deletion',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('Deletion successful');
}else{
show_Msg_success('Deletion failed');
},
error: function(xhr, textStatus, errorThrown) {
//called when there is an error
});
},data.id);
}
function admin_content_del (id) {
var data=listData[id];
show_Msg('Confirm deletion',data.content,'Confirm deletion',function(delId){
$.ajax({
URL: 'http://localhost/l/index.php',
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('Deletion successful');
}else{
Show_Msg_success('Deletion failed');
}
},
error: function(xhr, textStatus, errorThrown) {
//called when there is an error
}
});
},data.id);
}
2. setTimeout delays the execution of events. This message is really good and very commonly used, but this method of clearing messages is simple and crude.
[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='
/**
* 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='
$(strTag).prependTo('#main');
setTimeout(function(){
$(".alert").alert('close');
},3000);
}
3. It is better to use pure DOM to select checkbox. The arrt() method of jquery is cheating
checkbox.attr('checked',$(this).get()[0].checked);
The checkbox is checked, but it works for the first time and also for the second time. After the third time, it strangely fails. The problem is not the truth.
[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.length; i++) {
checkbox[i].checked = bool;
};
});
$("#mainData tr").each(function(index) {
$(this).click(function() {
If (index == 0) {
var val = checkbox.eq(index);
val = val.get()[0];
var bool = val.checked;
//alert(index);
If (bool) {
val.checked = false;
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;
Checkbox[i].checked = bool;
};
});
$("#mainData tr").each(function(index) {
$(this).click(function() {
} else {
var val = checkbox.eq(index);
val = val.get()[0];
//alert(index);
If (bool) {
val.checked = false;
} else {
val.checked = true;
}
});
}); I did some research and wrote a test code, but still to no avail. Those who don’t know the truth can’t be selected.

4. After talking so much, there are no renderings.
5. The title says it’s about PHP practice, but the previous posts are all PHP codes. . Posted below is the php code for batch deletion
[php] /**
* Used to delete messages in batches
*/
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);
}
/**
* Used to delete messages in batches
*/
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);
}That’s all the php code I wrote today. . Most of it is javascript
I posted admin.js for everyone to watch.
[javascript] // JavaScript Document
$(document).ready(function(e) {
$("#menu a").click(function() {
switch ($(this).text()) {
case 'All messages':
admin_content(1);
break;

$("#main #mainData").load('admin_config.html?r='+Math.random());
break;

//$("#start").click();
