php+ajax method to automatically save articles,

The example in this article describes the method of php+ajax to realize automatic saving of articles. Share it with everyone for your reference. The specific analysis is as follows:

The method of automatically saving articles in php+ajax is mainly to facilitate users and improve user experience. We use ajax to save the data as temporary data. Like csdn, it can automatically save the user's data. In this way, a power outage will occur. Unexpectedly, all the data you edited will be lost.

This is part of the core of auto-saving drafts,

autosavetime(sec) This function is used to start timing

clearTimeout(autosavetimer); clear timer

document.getElementById('autosavetimebox').innerHTML=sec+"seconds"; Get the autosavetimebox object in the page and write a countdown to it

Copy code The code is as follows:

if(sec>0) {
autosavetimer = setTimeout("autosavetime("+sec+"-1)",1000);　
//Here is if sec>0, the autosavetime function will be executed once in the first second, and the value of sec-1 will be written into the autosavetimebox
}else {
var title=document.getElementById('title');
If(title.value!=''){
autosave_post();
}else{
document.getElementById('autosavetimebox').innerHTML='No need to save'; }
}

This part is when the condition of sec>0 is not established, haha, when sec<=0, the save draft will be executed. First, it will determine whether the title of the article is empty. If it is not empty, the autosave_post() function will be executed. , otherwise write 'no need to save'.

The php code is as follows:

Copy code The code is as follows:

自动保存的js代码,代码如下:

复制代码代码如下:

var autosavetimer;
function autosavetime(sec) {
   clearTimeout(autosavetimer);
   document.getElementById('autosavetimebox').innerHTML=sec+"秒";
   if(sec>0) {
       autosavetimer = setTimeout("autosavetime("+sec+"-1)",1000);
   }else {
       var blogtitle=document.getElementById('title');
       if(blogtitle.value!=''){
           autosave_post();
       }else{
           document.getElementById('autosavetimebox').innerHTML='不用保存';
       }
   }
}
function startimer()
{
    var starttime=document.getElementById('autosavetimebox').innerHTML;
    if(starttime=='保存成功，您可以在发生意外的时候载入草稿' || starttime=='您还没有添写信息，不用保存草稿')
    {
        starttime='60';
    }else{
        starttime=starttime.replace('秒','');
    }
    var autosavefunbox=document.getElementById('autosavefunbox');
    autosavefunbox.innerHTML='停止计时';
    starttime==0 ? starttime=60 : starttime=starttime;
    autosavetime(starttime);
}
function stoptimer()
{
    var autosavefunbox=document.getElementById('autosavefunbox');
    autosavefunbox.innerHTML='开始计时';
    clearTimeout(autosavetimer);
}

I hope this article will be helpful to everyone’s PHP programming design.
