1下面是基本的发送表单代码
2 检查发送内容的js
var dx ='';
function checksay( )
{
//不允许发送空的发言
if(document.inputform.msg.value=='')
{
document.inputform.msg.focus();
return false;
}
//不允许重复发言,内容相同,对象相同
if ((document.inputform.msg.value==document.inputform.message.value)&&(document.inputform.talkto.value==dx))
{
alert('发言不能重复');
document.inputform.msg.focus();
return false;
}
//两次发言内容的间隔不能小于1秒,或者发言字数大于间隔*3
t2=(new Date()).getTime()/1000;
if(((t2-t1)<1)||((t2-t1)*3
document.inputform.msg.focus();
return false;
}
//更新时间
t1=t2;
document.inputform.showsign.value=1;
//保存上次发言内容
document.inputform.message.value =document.inputform.msg.value;
//清空发言内容
document.inputform.msg.value ='';
//保存发言对象
dx=document.inputform.talkto.value;
//定位焦点
document.inputform.msg.focus();
//返回
return(true);
}
3调用信息发送程序,发布聊天者已经进入的信息
<script> <br>parent.bl.document.open(); <br>parent.bl.document.write("<meta http-equiv='refresh' content='0;url=messagesend.php?name=<? print($name); ?>&&action=enter&&pass=<? print($pass); ?>'>") <br>parent.bl.document.close(); <br></script>
发言由messagesend.php处理完成,注意输出对象为bl,也就是处理发言的框架名称,这样保证发言框架的页面内容的完整

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.
