如何设定一个有提交年份的变量,以区别2种行为,因此,提交国将首次在数据库中加入,第二次更新数据库价值。
感谢。
取决于你们的执行情况,如果是 s。
如果说是麻风,你想说明一下一下,它在某些地方做了更新。
<input type="hidden" id="formUpdate" value="0" />
第一部分
document.getElementById( formUpdate ).value = 1; // and on the submit, check if it s 0 or 1
如果送入服务器,如果再次提交表格,你可以将表格列入代码,那么,你可以获得“请购书”(例如,与网址,任何途径)。
希望有助于
