一般我们用
requestgetParameter(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=requestgetParameterNames();
while(paramNameshasMoreElements()){String paramName=(String)paramNamesnextElement();}
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)p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:)
requestgetParameter(value);//这个最熟悉获得文本框的值
(Enumeration)requestgetParameterNames();//获得文本框的名字
(String[])requestgetParameterValues(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=linesrowslength;
var row = TableinsertRow(Tablerowslength);
var col = rowinsertCell();
colinnerHTML = <INPUT id=line[+i+][name] name=line+i+name SIZE=>;
col = rowinsertCell();
colinnerHTML = <INPUT id=line[+i+][name]name=line+i+name SIZE=>;
col = rowinsertCell();
colinnerHTML = <INPUT id=line[+i+][name] name=line+i+name SIZE=>;
col = rowinsertCell();
colinnerHTML = <INPUT id=line[+i+][name] name=line+i+name SIZE=>;
}
function tbladdrows(items)
{
for( i = ; i <= items ; i++)
{
tbladdrow();
}
}
function delrow()
{
if(linesrowslength==)
{
return false;
}
linesdeleteRow();
}
</script>
