字符串数组的forEach循环

Question

I have a string array(APN) in my bean(accessed as header). I am accessing it like this

<c:forEach var="apn" items="${header.APN}" >
    var g = apn;
    if (g.length!=0 && g!="null"){
        if(counter == 1){
            count=0;
             $("#img0").show();
             $("#apn0").show();
             $("#rtu0").show();

        }
        if(counter == 2){
            count=1;
             $("#img0").hide();
             $("#apn0").show();
             $("#rtu0").show();
             $("#img1").show();
             $("#apn1").show();
             $("#rtu1").show();
             $("#removeimg1").show(); 

        }
        if(counter == 3){
            count=2;
             $("#img0").hide();
             $("#apn0").show();
             $("#rtu0").show();
             $("#img1").hide();
             $("#apn1").show();
             $("#rtu1").show();
             $("#removeimg1").hide();
             $("#img2").show();
             $("#apn2").show();
             $("#rtu2").show();
             $("#removeimg2").show(); 

        }
    }
</c:forEach>

When I keep an alert after

var g = apn;

Alert is not popped up. I have some text boxes in my UI. When I press on + icon(rendered in the form of image), another set of text boxes appear to enter multiple values. My code is not working. Can anyone help me out

Answer 1

Seems you need an } just before /c:out . I don't know if this is the cause of your problem, i just noticed it.

Answer 2

I think your assignation part is incorrect. Try this -

var g = ${apn};
