Question

我正在使用dojo.js制作带滚动功能的下拉框，这不是标准select语句的原生。

我已经设法创建了下拉菜单，但是我很难使用select语句的标准onchange属性来执行它。 onchange =＆＃34; updateData（）＆＃34;在这种情况下。

感谢任何帮助。

Answer 1

var dropDown = new Select({
               name: "select2",
               id: "projectDropDown",
               onChange: function (value) 
               {
                 //console.log("project Id: ", this.get("value"))
                 reScopeProjectContext(value,satpcontext);
               },
               store: projectStore,
               labelAttr: "name",
               value: projectInContext,
               }).placeAt(win.body()).startup();

updatedata函数是在声明选择小部件之后定义的。这不会起作用请尝试以下代码。

<!DOCTYPE html>
<html>
<head>
    <link href="dojo/dojo-release-1.9.3-src/dijit/themes/claro/claro.css" rel="stylesheet"/>
    <script type="text/javascript">
        dojoConfig = {
            async: true,
            parseOnLoad: true
        };
    </script>
    <script type="text/javascript" src="dojo/dojo-release-1.9.3-src/dojo/dojo.js"></script>
    <script type="text/javascript">
        require(["dojo/parser", "dijit/form/Select"],function(parser){
            parser.parse();

        });
        function updateData(){
            alert("Onchange function called");
        }

    </script>
</head>
<body class="claro">
<select name="select1" data-dojo-type="dijit/form/Select" onchange="updateData()">
    <option value="A">A</option>
    <option value="B">B</option>
    <option value="C">C</option>
</select>
</body>
