使用Bean对象中的JSON构造数组

Question

Hello all I have a bean that has 3 getters. In the JSP I use JSTL to iterate over the bean to populate a table. I have saome javascript I need to do the same thing to construct an array. Here it is hardcoded, but how can I contruct it by itearing over a bean?

Bean: This is how I do it in the JSP using JSTL

<c:forEach var="bean" items="${beans}">
     ${bean.month}       
     </c:forEach>

How Can I do the same thing here:

Javascript:

"categories": [{
    "category": [{
       "label": "Oct"
    }, {
        "label": "Nov"
    }, {
        "label": "Dec"
    }, {
       "label": "Jan"
    }, {
        "label": "Feb"
    }, {
        "label": "Mar"
    }, {
        "label": "Apr"
    }, {
        "label": "May"
    }, {
        "label": "Jun"
    }, {
        "label": "Jul"
    }, {
        "label": "Aug"
    }, {
        "label": "Sep"
    }]     
    }]

Trying to do something like this in javascript

 <c:forEach var="bean" items="${beans}">
     [{
       "label": " ${bean.month}"
    },         
     </c:forEach>

Answer 1

I am not well experienced in JSTL. This is a guess based on the experience I have in PHP.

var array = [
<c:forEach var="bean" items="${beans}" varStatus="beanStatus">
    {
        "label": "${bean.month}"
    }
    <c:if test="${!beanStatus.last}">  // put comma after all item, but last one
         ,
    </c:if>          
 </c:forEach>
];

or

var array = [];
<c:forEach var="bean" items="${beans}">
    array.push({
        "label": "${bean.month}"
    });         
</c:forEach>

Answer 2

var category = [], // new Array
    i,
    newCategory;

for (i = 0; i < beans.length; i += 1) {
    newCategory = {}; // new object
    newCategory.label = beans[i].month;
    category.push(newCategory);
}
