Question

我正在慢慢构建包含表单的弹出对话框的功能。它有一个例外。在按钮上的onClick事件中，我想更新表单中的值。它会更新值，但仅限于输入到表单中的div（emailForm）。我有div设置显示所以我可以看到更新。如何在myDialog对象中更新它？

<div id="emailForm" Executive Director>
<h1>Contact Form</h1>
<p>Feel free to drop us a line.</p>
<form id="contact-form" action="confirmation.php" method="post">
    <fieldset class="contact-fieldset">
        <ol>
            <li>
                <label for="to">To:</label>
                <input id="to" name="to" type="text" size="40" value="Staff" disabled>
            </li>
            <li>
                <label for="message">Message:</label>
                <textarea id="message" name="message"></textarea>
            </li>
        </ol>
        <input type="submit" class="contact-submit" value="Send">
    </fieldset>
</form>
</div>
<script>
require(["dojo/dom",
        "dijit/Dialog",
        "dijit/form/TextBox",
        "dijit/form/Textarea",
        "dojo/domReady!"],
        function(dom, Dialog, TextBox, TextArea)
{
    toText = new TextBox({readOnly: "readOnly" , value: "Staff"},"to");
    messageText = new TextArea({placeholder: "Your message"},message);

    var emForm = dom.byId("emailForm").innerHTML;

    myDialog = new Dialog({
        title: "My Dialog",
        content: emForm,
        style: "width: 600px"
    });
});

require(["dijit/form/Button",
        "dojo/domReady!"],
        function(Button)
{
    var showEmailBtn = new Button({
    onClick: function(evt){
        toText.set("value","Executive Director");
        myDialog.show(); } },
    "showEmail");
});
</script>

更新

根据tik27对问题的描述，我尝试了以下测试：

<script>
require(["dojo/dom",
        "dijit/Dialog",
        "dijit/form/TextBox",
        "dijit/form/Textarea",
        "dojo/domReady!"],
        function(dom, Dialog, TextBox, TextArea)
{
    var emForm = '<div id="emailForm" Executive Director><h1>Contact Form</h1><form id="contact-form" action="confirmation.php" method="post"><fieldset class="contact-fieldset"><ol><li><label for="to">To:</label><input id="to" name="to" type="text" size="40" value="Gereral" disabled></li></ol><input type="submit" class="contact-submit" value="Send"></fieldset></form></div>';

    myDialog = new Dialog({
        title: "My Dialog",
        content: emForm,
        style: "width: 600px"
    });
    toText = new TextBox({readOnly: "readOnly" , value: "Staff"},"to");
});

require(["dojo/dom",
        "dijit/form/Button",
        "dojo/domReady!"],
        function(dom, Button)
{
    var showEmailBtn = new Button({
    onClick: function(evt){
        toText.set("value","Executive Director");
        myDialog.show(); } },
    "showEmail");
});
</script>

这解决了这个问题。显示的html只是对完整表单的一个小测试。如何将html与脚本分开，然后在不重复id的情况下将其带入？我查看了模板，但这似乎有些过分。

更新2

再次，根据Tik27的一些建议，我试过这个：

<script id="emailHTML" type="text/template">
    <div id="emailForm" Executive Director>
        <!-- Same html as above in emailForm -->
    </div>
</script>
<script>
require(["dojo/dom",
        "dijit/Dialog",
        "dijit/form/TextBox",
        "dijit/form/Textarea",
        "dojo/domReady!"],
        function(dom, Dialog, TextBox, TextArea)
{

    myDialog = new Dialog({
        title: "My Dialog",
        content: dom.byId("emailHTML").textContent,
        style: "width: 600px"
    });
    toText = new TextBox({readOnly: "readOnly" , value: "Staff"},"to");
});

require(["dojo/dom",
        "dijit/form/Button",
        "dojo/domReady!"],
        function(dom, Button)
{
    var showEmailBtn = new Button({
    onClick: function(evt){
        toText.set("value","Executive Director");
        myDialog.show(); } },
    "showEmail");
});
</script>

浏览器忽略文本/模板脚本中的任何内容，因此id仅添加一次到DOM。在此站点上搜索有关脚本类型的更多信息。

这里的问题与你这样做的方式是，最终会输入id =“to”。 Ids在html中应该是唯一的。如果你想这样做，我建议你把你的表单信息放到一个带有type =“text / template”的脚本标签中。

但是你有没有理由不以声明方式创建它？

<div id="emailForm" data-dojo-type="dijit.Dialog" style="display:none">
<h1>Contact Form</h1>
<p>Feel free to drop us a line.</p>
<form id="contact-form" action="confirmation.php" method="post">
    <fieldset class="contact-fieldset">
        <ol>
            <li>
                <label for="to">To:</label>
                <input data-dojo-type="dijit.form.TextBox" data-dojo-props="readOnly: 'readOnly' , value:'Staff'" id="to" name="to" type="text" size="40">
            </li>
            <li>
                <label for="message">Message:</label>
<textarea id="message" name="message" data-dojo-type="dijit.form.Textarea" data-dojo-props="placeholder: 'Your message'"></textarea>
            </li>
        </ol>
        <input type="submit" class="contact-submit" value="Send">
    </fieldset>
</form>
</div>

<div id="showEmail">Show</div>

<script>
require(["dijit/form/Button",
    "dijit/registry","dojo/dom",
    "dijit/Dialog",
    "dijit/form/TextBox",
    "dijit/form/Textarea"],
        function(Button,registry)
{
    var showEmailBtn = new Button({
    onClick: function(evt){

        registry.byId("emailForm").show();
        registry.byId("to").set("value","Executive Director");
    } }, "showEmail");
});
</script>
