  • 工作学习 / IT技术讨论 / 请教：Javascript变量显示, thanks! -cloud2001(卷云溶月); 2003-4-8 {132} (#1130025@0)
    var test='123';
    use alert to pop up a message '123' not 'test', how to write the script.
    it seems alert(test) doesn't work
    • It should be ok. -guestagain(guest again); 2003-4-8 (#1130033@0)
    • it works. 你怎么写的？ -bingle(bingle); 2003-4-8 (#1130047@0)
    • 换个变量名试试看, 不要用test, 比如用 a -tztz(tztz); 2003-4-8 (#1130050@0)
    • Should I declare the variable in <head>?? -cloud2001(卷云溶月); 2003-4-8 (#1130060@0)
      • Maybe my question is not clear. I want to use the variable in jsp. -cloud2001(卷云溶月); 2003-4-8 {199} (#1130071@0)
        I don't want to use get or post method, just want to get parent window's fields' value through javascript variables, and use out.println() to display.
        Maybe it's not a good way, any suggestions?
        • 可以用hidden input来传递。 -luoboyang(萝卜秧); 2003-4-8 (#1130080@0)
          • hidden field 肯定能做，但页面看来不整齐，debug也麻烦。 -bluegreysky(绿袖); 2003-4-8 (#1130118@0)
            • 她不想用post, get嘛。 -luoboyang(萝卜秧); 2003-4-8 (#1130122@0)
              • 我就是想说这个东东不是好东东 -bluegreysky(绿袖); 2003-4-8 (#1130147@0)
            • I don't think so. -guestagain(guest again); 2003-4-8 (#1130161@0)
        • 你把client side script 和server side script搞混了。 -guestagain(guest again); 2003-4-8 (#1130084@0)
          • I want to mix the clien/server side scripts together, should have some ways. -cloud2001(卷云溶月); 2003-4-8 (#1130114@0)
            • I don't think so. why not tell us what you want and we can find out a solution. -guestagain(guest again); 2003-4-8 (#1130127@0)

                two jsp page: parent.jsp, popup.jsp
                in parent.jsp, use html link to open popup.jsp, don't want to use get method to pass parameters. For example, parent has staff name, staff id,
                popup.jsp has a dropdown list to display staff name with value of staff id.
                I want to get the value of parent's staff name and id using javascript
                variables: var staff_name = opener.document.staff_name.value; var staff_id = opener.document.staff_id.value, then using
                out.println("<option value=staff_id>staff_name</opotion>") to display the value in the dropdown list.
                my question is I cannot display staff_id and staff_name properly. I know something wrong with out.println() function, but how to fix it?
                Any suggestions are welcomed!
                • 就象#1130084说的，你把client side script 和server side script搞混了。staff_name是jscript中的变量，是在Client端运行得到的，而out.println是JSP中的语句，在服务器端运行。 -bingle(bingle); 2003-4-9 (#1130744@0)
                • out.println("<option value=staff_id>staff_name</opotion>") -goodbaby(小宝); 2003-4-9 {96} (#1130751@0)
                  shouldnt it be
                  out.println("<option value=" + staff_id + ">" + staff_name + "</opotion>")
    • Thanks, everyboday, good night! -cloud2001(卷云溶月); 2003-4-8 (#1130115@0)
    • Try my code here, there may be many ways to do it, but this one works as you expect. -xiaoxiao(笑笑); 2003-4-9 {1536} (#1130727@0)

      • Thank you very much, it works! I didn't think about to use 'document.write'. -cloud2001(卷云溶月); 2003-4-9 (#1130815@0)
        • 'document.write' is a client side script, in that solution, it works, but no server side script used. so there is no reason to use a jsp file. -guestagain(guest again); 2003-4-9 (#1130918@0)

        • I think cloud2001 is devloping some web application, please see #1130178, what's shown here is just an example, you are right jsp is not needed for this example, but that's what the user asked. :) -xiaoxiao(笑笑); 2003-4-9 (#1130961@0)
          • your solution does not meet the requirement because no server side script is used to handle the data inputed at client side. -guestagain(guest again); 2003-4-9 (#1131074@0)
