This article mainly introduces the method of Ajax to realize real-time editing of tables, which has a good reference and value for learning ajax. Let's follow the editor to see how PHP Ajax implements real-time editing of tables

How cool would it be if we could operate all the data in a table on this page? (It’s great to use to stir-fry chicken)!

This function can be achieved using Ajax. Without further ado, let me post the demo I wrote below, haha. I am more accustomed to the TP framework (3.2) I use.

The first is the HTML code part: 


<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>AJAX实时编辑</title>
<script src="/Public/jquery-1.7.2.min.js"></script>
</head>
<body>
<center>
<table border="1" width="1000" id="g_table">
<tr>
<!-- <th>ID</th> -->
<th>TAB1</th>
<th>TAB2</th>
<th>TAB3</th>
<th>TAB4</th>
<th><span onclick="add()">添加</span></th>
</tr>
<foreach name="tablist" item="vv">
<tr>
<!-- <td>{$vv.id}</td> -->
<input type="hidden" name="id" value="{$vv.id}">
<td>{$vv.tab1}</td>
<td>{$vv.tab2}</td>
<td>{$vv.tab3}</td>
<td>{$vv.tab4}</td>
<td><span onclick="del(this)" id="del">删除</span><span onclick="edit(this)" id="edit">修改</span></td>
</tr>
</foreach>
</table>
</center>
</body>
<script>
var g_table = $("#g_table");
function add(){
var addRow = $("<tr></tr>");

g_table.append(addRow);
for(var i = 0;i < 4;i++){
var col_td = $("<td><input type=&#39;text&#39; /></td>");
addRow.append(col_td);
}
var col_opt = $("<td></td>");
var confirmBtn = $("<a href=&#39;javascript:;&#39;>确认</a>");
var cancelBtn = $("<a href=&#39;javascript:;&#39;>取消</a>");
cancelBtn.click(function(){
window.location.reload();
});
confirmBtn.click(function(){
var currentRow = $(this).parent().parent();
var input_files = currentRow.find("input");
var post_files = {};
for(var i = 0 , j = input_files.length;i < j;i++){
post_files[&#39;clo_&#39; + i] = input_files[i].value;
}
// $.post("{:U(&#39;ajax/add&#39;)}",post_files,function(msg){
// debugger;
// })
$.ajax({
type: &#39;post&#39;,
url : "{:U(&#39;ajax/add&#39;)}",
data: {post_files},
success:function(msg){
alert(msg);
window.location.reload();
}
})
});
col_opt.append(confirmBtn);
col_opt.append(cancelBtn);
addRow.append(col_opt);
}
function del(obj){
var id = $(obj).parent().prev().prev().prev().prev().prev().val();
$.ajax({
type: &#39;post&#39;,
url: "{:U(&#39;ajax/del&#39;)}",
data: {id:id},
success:function(msg){
alert(msg);
}
})
$(obj).parent().parent().remove();
}
function edit(obj){
var id = $(obj).parent().prev().prev().prev().prev().prev().val();
for(var i = 1;i < 5;i++){
var temp = "<td><input type=&#39;text&#39; value=&#39;" + $(obj).parent().parent().children().eq(i).html() + "&#39;/></td>";
$(obj).parent().parent().children().eq(i).replaceWith(temp);
}
var confirmBtn1 = $("<span id=&#39;confirm&#39;>确认</span>");
var cancelBtn1 = $("<span onclick=&#39;back()&#39;>取消</span>");
confirmBtn1.click(function(){
var currentRow = $(this).parent().parent();
var input_files = currentRow.find("input");
var post_files = {};
for(var i = 0 , j = input_files.length;i < j;i++){
post_files[&#39;clo_&#39; + i] = input_files[i].value;
}
$.ajax({
type: &#39;post&#39;,
url : "{:U(&#39;ajax/edit&#39;)}",
data: {post_files:post_files,id:id},
success:function(msg){
alert(msg);
window.location.reload();
}
}) 
});
$(obj).prev().replaceWith(confirmBtn1);
$(obj).replaceWith(cancelBtn1);

}
function back(){
location.reload();
} 
</script>
</html>


The following is the controller Code in: 

<?php 

namespace Home\Controller;
use Think\Controller;
class AjaxController extends Controller{
public function index(){
$tab = M(&#39;table&#39;);
$tablist = $tab->select();
$this->assign(&#39;tablist&#39;,$tablist);
$this->display();
}
public function del(){
$map[&#39;id&#39;] = $_POST[&#39;id&#39;];
$tab = M(&#39;table&#39;);
$info = $tab->where($map)->delete();
if($info){
$this->ajaxReturn("删除成功");
}else{
$this->ajaxReturn("删除失败");
}

}
public function add(){

$map[&#39;tab1&#39;] = $_POST[&#39;post_files&#39;][&#39;clo_0&#39;];
$map[&#39;tab2&#39;] = $_POST[&#39;post_files&#39;][&#39;clo_1&#39;];
$map[&#39;tab3&#39;] = $_POST[&#39;post_files&#39;][&#39;clo_2&#39;];
$map[&#39;tab4&#39;] = $_POST[&#39;post_files&#39;][&#39;clo_3&#39;];
$tab = M(&#39;table&#39;);
$res = $tab->add($map);
if($res){
$this->ajaxReturn("添加成功");
}else{
$this->ajaxReturn("添加失败");
}
}
public function edit(){
$id = $_POST[&#39;id&#39;];
$map[&#39;tab1&#39;] = $_POST[&#39;post_files&#39;][&#39;clo_1&#39;];
$map[&#39;tab2&#39;] = $_POST[&#39;post_files&#39;][&#39;clo_2&#39;];
$map[&#39;tab3&#39;] = $_POST[&#39;post_files&#39;][&#39;clo_3&#39;];
$map[&#39;tab4&#39;] = $_POST[&#39;post_files&#39;][&#39;clo_4&#39;];
// dump($map);exit;
$tab = M(&#39;table&#39;);
$res = $tab->where(&#39;id=&#39;.$id)->save($map);
if($res){
$this->ajaxReturn("更新成功");
}else{
$this->ajaxReturn("更新失败");
}
}
}
