Question

我使用dojo创建了一个网格。我有一个带有输入字段的表单，当我输入值并单击＆＃34;添加行＆＃34;按钮输入字段不会附加到网格。删除选项工作正常，但添加行不起作用。我已经附上了jsfiddle的链接，请参阅更多。

form = new Form({
    onSubmit: function(evt) {
        evt.preventDefault();
        var formValue = this.get("value");
        dataStore.newItem(formValue);
    }
}, "formContainer");
form.startup();
});

Answer 1

您的HTML代码存在一些问题。不需要form元素。您只需要div并将dijit.form.Form放在div元素中。并且，submit按钮需要位于div内。它会自动被触发。

请参阅更新的小提琴：JSFiddle

还有一件事，要向商店添加数据，您必须为newItem提供ID。 Store不接受没有id的元素。

Answer 2

完全同意@Himanshu 你的HTML很奇怪如果要使用submit按钮，则必须将其放在<form>元素内。

此外，仍然像@Himanshu所说，您必须提供id以便用户newItem
