Question

我试图测试一个java脚本函数，该函数的目的是获取用户选择的表单元素的值。特别是一个单选按钮。我的目标是在另一个函数中使用此函数来计算总价。但就目前而言，我只想确保此函数返回所选单选按钮的值。

<html>
    <head>
    </head>
    <body>
        <form name="testForm"> 
            <legend>Calculate your square feet</legend>                
            </br>
            <label> What size plants are you starting with ? </label>
            </br>
            </br>           
            <input type="radio"  name="plantType" value="16"/>Seeds, havn't started yet</label>
            </br>
            <input type="radio"  name="plantType" value="16"/> Seedlings, less than 2ft high</label>
            </br>
            <input type="radio"  name="plantType" value="32"/> Juvenile, 2 - 4ft high</label>
            </br>
            <input type="radio"  name="plantType" value="64"/> Adult, 4ft or higher</label>
            </br>

        </form>

    <script type="text/javascript"> 




var plant_name =  new Array();
plant_name[16] = 16;
plant_name[16] = 16;
plant_name[32] = 32;
plant_name[32] = 64;



function getPlantSize() {
                var plantSize = 0;
                var theForm = document.testForm;
                var selectedPlant = theForm.plantType;
                for (var i = 0; i < plantType.length; i++)
    {
        if (plantType[i].checked)
    {
        plantSize = plant_name.[selectedPlant[i].value];
        break;
    }
        document.write (plantSize);
    }




}


    </script>

    </body>
</html>
