如何以编程方式在Dijit Dialog中制作和显示表单？

Question

我一直试图弄清楚如何使用Dojo 1.7在Dialog中创建和显示表单.

我希望我的对话框看起来像这样:

我见过的所有样本都使用Markup,但没有使用AMD

创建对话框时,可以使用窗口小部件(例如表单)作为内容.所以,例如,您可以这样做:

require([
    "dijit/Dialog", 
    "dijit/form/Form", 
    "dijit/form/TextBox", 
    "dijit/form/Button", 
    "dojo/domReady!" 
], function(Dialog, Form, TextBox, Button) 
{
    var form = new Form();

    new TextBox({
        placeHolder: "Name"
    }).placeAt(form.containerNode);

    new Button({
      label: "OK"
    }).placeAt(form.containerNode);

    var dia = new Dialog({
        content: form,
        title: "Dialog with form",
        style: "width: 300px; height: 300px;"
    });
    form.startup();
    dia.show();
});//~require

require()由Dojo提供.它加载依赖项(Form,Dialog等),然后运行创建小部件的给定函数.但是,因为我们包含domReady!在依赖项中,所以Dojo确保DOM已完全加载并准备好.

因为我也有dia.show()该功能,所以只要页面打开就会显示对话框.假设您想要在单击页面上的某个按钮时显示对话框:

require([
    "dijit/Dialog", 
    "dijit/form/Form", 
    "dijit/form/TextBox", 
    "dijit/form/Button",
    "dojo/on",      // Added this!
    "dojo/domReady!" 
], function(Dialog, Form, TextBox, Button, onEvent) 
{
    // ... as above, we create the dialog and form when the page loads
    // but it remains hidden until we call dia.show() ...
    form.startup();
    // dia.show();  Commented out this!

    onEvent(document.getElementById("someButtonOnYourPage"), "click", 
        function()
        {
            dia.show();
        });
});//~require
