设置Dijit.Form.Textarea的值 [英] Set Value of Dijit.Form.Textarea

问题描述

我有一个dijit对话框，其中包含一个我要自动填充的表单。我可以使用其中的表单来显示对话框，但是我无法设置表单中的文本区域的值。这是包含html的div。

 < div dojoType =dijit.Dialogid =formDialogtitle =Form Dialog> 
< table> 
< tr> 
< td> 
< label for =desc> 
说明：
< / label> 
< / td> 
< td> 
 
< textarea id =descname =descdojoType =dijit.form.Textareastyle =width：200px;>< / textarea> 
  

SAVE


关闭

我可以通过执行

var formDlg = dijit.byId（formDialog）;
formDlg.show（）;

但我的问题是设置textarea的值为desc。我已经尝试过多个东西，但是我知道我需要

  var test = dijit.byId（desc）; 
  

但如果我设置任何测试属性，例如

  test.value =foo; 
 test.textContent =foo; 
 test.innerHTML =foo; 
 test.srcNodeRef =foo; 
  

该值永远不会保存并显示在textarea内。有这样做的伎俩吗？任何帮助都会很棒。谢谢

解决方案

  var test = dijit.byId（desc）; 
 test.set（value，foo）; 
  

..应该做的伎俩，我想。 Dojo中的大多数小部件使用集方法（以前 attr ）设置属性值，而不是直接像您一样操纵它们我试图做。您还可以通过传递一个对象来一次设置多个属性：

  var test = dijit.byId（desc）; 
 test.set（{value：foo，name：someName}）; 
  

I have a dijit dialog that contains a form that I want to auto-populate. I can get the dialog to display with the form in it, but I have been unable to set the value of a text area within the form. Here is the div that houses the html.

<div dojoType="dijit.Dialog" id="formDialog" title="Form Dialog" >
<table>
    <tr>
        <td>
            <label for="desc">
                Description:
            </label>
        </td>
        <td>

        <textarea id="desc" name="desc" dojoType="dijit.form.Textarea" style="width:200px;"></textarea>

SAVE CLOSE

I can get this to display just fine by doing

var formDlg = dijit.byId("formDialog"); formDlg.show();

But the issue I have is setting the value of the textarea called "desc". I have tried multiple things, but I know I need to

var test = dijit.byId("desc");

but if I set any property of test, such as

   test.value = "foo";
   test.textContent = "foo";
   test.innerHTML = "foo";
   test.srcNodeRef = "foo";

The value is never saved and displayed inside the textarea. Is there a trick to doing this? Any help would be great. Thanks

解决方案

var test = dijit.byId("desc");
test.set("value", "foo");

..should do the trick, I think. Most widgets in Dojo use the set method (formerly attr) to set property values, instead of manipulating them directly like you've tried to do. You can also set multiple properties in one go by passing an object:

var test = dijit.byId("desc");
test.set({"value": "foo", "name": "someName"});
