Java的批量添加数据,多个字段同时添加多条数据,我不知道你遇到过没有。今天我们就以一个具体的实例来说一下Java的批量添加数据,面向的是Oracle数据库。

前台页面:

<span style="font-size:14px;"><body class="main_body" scroll="no"> <div class="employee_gun_dong">   <form name="webform" method="post">         <div class="main_content_bg">         <div

这样,java多字段、多条数据批量添加的例子就完成了,主要要注意前台页面叠加出现多行的js函数和后台的添加和更新方法,用list接收,循环遍历进行添加。除此之外这里我想说一下下面这段代码:

复制代码 代码如下:
<span style="font-family:KaiTi_GB2312;font-size:14px;">$(function(){ 
    loadCheck(); 
});</span>  
  

它就是如下代码的缩写:

复制代码 代码如下:
<span style="font-family:KaiTi_GB2312;font-size:14px;"> $(document).ready(function(){ 
        loadCheck(); 
});</span> 

其实这个代码和下面的代码是一个意思:

复制代码 代码如下:
<span style="font-family:KaiTi_GB2312;font-size:14px;">window.onload=function(){ 
       loadCheck(); 
}</span>
   

这样就不用在body的onload事件里面调用,只需要在js程序段里面编写就可以了。虽然下面的代码可以和上面两个互换,但他们之间又有不同。首先是执行时间不同,$(document).ready在页面框架下载完毕后就执行,而window.onload必须在页面全部加载完毕(包含图片下载)后才能执行。很明显前者的执行效率高于后者。再就是执行数量的不同,$(document).ready可以重复写多个,而且每次执行结果不同;而window.onload尽管可以执行多个,但仅输出最后一个执行结果,无法完成多个结果的输出。

以上就是本文的全部内容,希望对大家的学习有所帮助。
