直接使用<%= %>不行啊???

#4

红色部分lz可以用便利得到

可以直接赋值的

<%
for(int i ......){
%>

txt= txt + "<a image='http://www.qpsh.com/icon/443_209_3.jpg' info='"+"<%=url%>"+"' url='http://www.qpsh.com/' /> "

<%
}
%>

其中的url就是你便利的图片连接地址

复制的时候一定要有"" 例如："<%=aaa%>"

#5

复制的时候一定要有"" 例如：" <%=aaa%>" 中的"复制"------>赋值

#6

怎样在jsp中获得表单下拉框上的值，要或得一个数组吗？
用getParameterValues方法老出错啊！

#7

老大, txt串怎么在JSP 中组成出来;
我直接:
<%
String text="<a image='http://www.qpsh.com/icon/443_209_3.jpg'";
text=text+"....."

%>
不行啊???

#8

复制的时候一定要有"" 例如：" <%=aaa%>" 中的"复制"------>赋值

什么意思?

是在javascript 中可以这样写吗?
txt="<%=text%>"
text 是在jsp 文件中组成的串.

是这样吗?

写个完整的给你吧，看你好像没理解。


<BODY bgcolor="#F7F7F7"> 
<DIV class=focusFlash> 
<DIV id=sasFlashFocus27> </DIV> 


<SCRIPT type=text/javascript> 
var txt="";

<% 
for(int i ......){ 
%> 

txt= txt + " <a image='http://www.qpsh.com/icon/443_209_3.jpg' info='"+" <%=url%>"+"' url='http://www.qpsh.com/' /> "  

<%

var sohuFlash2 = new sohuFlash("http://www.qpsh.com/icon/qpsh_com_tp2.swf", "27", 520, 205, "7"); 
sohuFlash2.addParam("quality", "high");

sohuFlash2.addVariable("txt",txt); 
sohuFlash2.write("sasFlashFocus27"); 
  </SCRIPT>

在for循环中添上你要遍历的List 在url那里添上从list中取出url

老大:

具体怎么写啊?

txt=" <a image='http://www.qpsh.com/icon/443_209_1.jpg' info='网页特效是用程序代码在网页中实现特殊效果或者特殊功能的一种技术' url='http://www.qpsh.com' /> <a image='http://www.qpsh.com/icon/443_209_2.jpg' info='它为网页活跃了气氛，增加了网站的亲和力。' url='http://www.qpsh.com' /> <a image='http://www.qpsh.com/icon/443_209_3.jpg' info='一般在你想添加特效的地方直接粘贴特效代码即可' url='http://www.qpsh.com/' /> <a image='http://www.qpsh.com/icon/443_209_4.jpg' info='在本站下载的特效代码，都有详细说明，按说明使用即可。' url='http://www.qpsh.com' />"

直接这样写,没有问题,可以正常显示图片;
------------------------------
现在的问题是:

这串内容现在我要在<% .... %> 之间写好,赋给一个String 变量text; 在javascriptscript 中再引用;

能不能详细点告诉哈~~~~~~~

试了好半天了,没有成功!!!!

#12

估计的你的调试方法不对,你每次改完,点击url后查看下源文件你就知道那写错了

<%String text="<a image='http://www.qpsh.略";%>

txt="<%=text%>"

#13

哈哈

终于测试通过了!

整半天是txt=<%=text%> 这句差了引好啊~~~~~~~

多谢谢两位@@@

给分给分!

引用 11 楼 happypolo 的回复:

按lz的意思，红色串的部分这样写就可以了吧~<%=text%>

PS：试试10楼koko的应该没问题~

#15

这串在JSP 中怎么写??? 我如下写取不出来啊!!!!
<%

String txt ="";
for
{
....
txt=txx+"<a image='/qjcf/attachments/"+savepath+"' info='"+doctitle1+"' url='http://www.qjcf.com.cn'/> ";

...
}
%>

#16

太怪了~~~

#17

txx写错了吧txt,有错要先看异常啊

#18

java 的变量不能直接这样传到javascript 里吧
