Question

在Firefox中开发Web地图应用程序后，我在Internet Explorer（公司标准）中测试了我的代码，发现dijit / form / Select使用最新的Esri JavaScript v3.7行为不端。

我看到的问题是，当使用v3.7时，Select不会更新/更改列表中的第一个选项。如果我将版本降低到3.6，它会按预期工作。

我尝试过7到10的IE浏览器模式，并且在所有这些模式之间遇到了相同的行为。有人可以证实他们正在经历同样的事情吗？

3.7中的示例 - http://jsbin.com/aVIsApO/1/edit

3.6中的示例 - http://jsbin.com/odIxETu/7/edit

            for (var i = 0; i < results.features.length; i++) {
                var id = results.features[i].attributes.TreeID;
                var desc = results.features[i].attributes.qSpecies;
                if (!testVals[id]) {
                    testVals[id] = true;
                    var selectElem = domConstruct.create("option",{ label: desc + " (" + id + ")", value: id });
                    frmTrees.addOption(selectElem);
                }
            }
        });

        frmTrees.on("change", function() {
            console.debug(frmTrees.get("value"));
        });
    });

});

不是创建DOM元素并将其传递给dijit / form / Select.addOption，而是传递一个带有label和value属性的简单对象：

qt.execute(query, function(results) {
    //var frm_domain_area = dom.byId("domain_area");
    var testVals = {};

    for (var i = 0; i < results.features.length; i++) {
        var id = results.features[i].attributes.TreeID;
        var desc = results.features[i].attributes.qSpecies;
        if (!testVals.hasOwnProperty(id)) {
            testVals[id] = true;
            var label = desc + " (" + id + ")";
            frmTrees.addOption({label: label, value: id});
        }
    }
});

dijit / form /使用Esri Javascript 3.7在Internet Explorer中选择已损坏
