Question

Java 里 out.print() 不工作

我在out.print里打出这样:
out.print("<A href='#' onclick='Javascript:window.open('Logon.jsp','','width=400,height=220')'>登录</A>")

但是运行后无法弹出新窗口
要怎么解决?

Answer 1

你里面的引号打乱了。 去掉两个引号试一试：
out.print("<A href='#' onclick=Javascript:window.open('Logon.jsp','','width=400,height=220')>登录</A>")
或者改为：
out.print("<A href='#' onclick=\"Javascript:window.open('Logon.jsp','','width=400,height=220')\">登录</A>")
看看

Answer 2

直接在jsp页面上写：<%out.print("<a href='#' onclick=\"JavaScript:window.open('Logon.jsp','','width=400,height=220')\">登录</a>");%>

\"转义为"

Answer 3

//我给个完整的servlet

import java.io.IOException;
import java.io.PrintWriter;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

public class HiServlet extends javax.servlet.http.HttpServlet implements
javax.servlet.Servlet {
static final long serialVersionUID = 1L;

public HiServlet() {
super();
}

protected void doGet(HttpServletRequest request,
HttpServletResponse response) throws ServletException, IOException {
this.doPost(request, response);
}

protected void doPost(HttpServletRequest request,
HttpServletResponse response) throws ServletException, IOException {
// 改成你的页面
String dist = "http://www.baidu.com";
String s = "<A href='#' onclick=\"Javascript:window.open('" + dist
+ "','','width=400,height=220')\">" + dist + "</A>";
PrintWriter writer = response.getWriter();
writer.print(s);
writer.flush();

}
}

Answer 4

你是在servlet里面打印的吧？
那个要有前后文的 不能只打印这一句
