Question

当用户登录表单到来时如何将光标放在文本输入中。我想将光标放在用户名文本输入中。。任何帮助是极大的赞赏！

Answer 1

您无法手动移动鼠标光标，但是，您可以在表单完成后始终将焦点设置在TextInput上：

<mx:Canvas creationComplete="onCreationComplete()">
   <mx:Script>
      <![CDATA[
         private function onCreationComplete():void
         {
            input.setFocus();
         }
      ]]>
   </mx:Script>
   <mx:TextInput id="input" />
</mx:Canvas>

与J_A_X的答案一致，如果您在应用程序首次加载时尝试将重点放在组件上，则还需要use some javascript to set the focus on your SWF。

以下是该文章的示例代码：

Javascript：

<script type="text/javascript">
function onFlexInitialized()
{
    //alert("onFlexInitialized");

    <!-- Force the browser to set flex app with focus -->
    document.getElementById("${application}").focus();
}
</script>

ActionScript：

/**
 * Constructor.
 */
public function AppController()
{
    FlexGlobals.topLevelApplication.addEventListener(FlexEvent.APPLICATION_COMPLETE, onAppComplete); // Flex 4
        //Application.application.addEventListener(FlexEvent.APPLICATION_COMPLETE, onAppComplete); // Flex 3
}

/**
 * Handles the application complete event.
 */
protected function onAppComplete(e:FlexEvent):void
{
    FlexGlobals.topLevelApplication.removeEventListener(FlexEvent.APPLICATION_COMPLETE, onAppComplete); // Flex 4
        //Application.application.removeEventListener(FlexEvent.APPLICATION_COMPLETE, onAppComplete); // Flex 3

    if(ExternalInterface.available)
    {
        ExternalInterface.call("onFlexInitialized");
    }
}

                if(myarr[i].names.toString().match(textinput.text)){
                        tempArr[j]=myarr[i];
                        j++;
                }else{

                }
                }

navigateToURL(new URLRequest("javascript: document.getElementById('XXX').focus();"), "_self"); 
userNameInput.setFocus();

其中XXX是swf文件的名称。
