一般,我们用
request.getParameter(“value”);
来获得静态html输入的值.然后不要忘记判断是否为空,是否含有特殊字符等.
还可以用
Enumeration paramNames=request.getParameterNames();
http://www.gaodaima.com/?p=44150jsP:JavaScript 实现输入多行动态输入
while(paramNames.hasMoreElements()){String paramName=(String)paramNames.nextElement();}
来收集<input type=”text” name=”name”/>中的name
但是我们每增加新的一行,参数名同上一行一样,那么,我们将如何获得value的值?
这里我又去看书(servlet 和 jsp 核心编程,极好的一本书,该讲的都讲了,读明白了它servlet/JSP也就可以说精通了)p70页里面:getParameterValues()返回字符串数组,然后我们用循环判断这个字符串数组的长度,再就是获得值了:)
request.getParameter(“value”);//这个最熟悉,获得文本框的值
(Enumeration)request.getParameterNames();//获得文本框的名字
(String[])request.getParameterValues(paramName);//获得静态html页相同的参数(多次出现)的值
*************html 页 javascript 代码:
<script language=”javascript”>
function tbladdrow()
{
var i=lines.rows.length;
var row = Table1.insertRow(Table1.rows.length);
var col = row.insertCell(0);
col.innerHTML = “<INPUT id=line[“+i+”][name1] name=line”+i+”name1 SIZE=10>”;
col = row.insertCell(1);
col.innerHTML = “<INPUT id=line[“+i+”][name2] name=line”+i+”name2 SIZE=10>”;
col = row.insertCell(2);
col.innerHTML = “<INPUT id=line[“+i+”][name3] name=line”+i+”name3 SIZE=10>”;
col = row.insertCell(3);
col.innerHTML = “<INPUT id=line[“+i+”][name4] name=line”+i+”name4 SIZE=10>”;
}
function tbladdrows(items)
{
for( i = 1 ; i <= items ; i++)
{
tbladdrow();
}
}
function delrow()
{
if(lines.rows.length==0)
{
return false ;
}
lines.deleteRow();
}
</script>
