onblur

Start with the onBlur function where the asynchronous server call is built .

先来看看onBlur函数，异步服务器调用在该函数内构建。

Select the onblur event in the list of events on the left side .

左面事件列表中选择onblur事件。

The onblur attribute of the nested component is also changed to clear the help message when the element loses the keyboard focus .

嵌套组件的onblur属性也发生更改，以在元素丢失键盘焦点时清除帮助消息。

As soon as you tab out of any input field in the table , JavaScript code attached to the onblur event runs .

一旦焦点离开表中任意输入栏，就会运行与onblur事件联系的JavaScript代码。

It then calls the jQuery blur () method , which binds a function to the onblur () event for the username field .

随后调用jQueryblur（）方法，后者将一个函数绑定到用户名字段的onblur（）事件。

Next , you 'll see how to build a custom component that modifies the onfocus and onblur attributes of every nested component that contains

下面，您将看到如何构建自定义组件，它修改每个包含

To do so , bind code to the username field 's onblur () event , which is triggered when the user 's cursor leaves the field .

为此，将代码绑定到用户名字段的onblur（）事件，该事件将在用户光标离开字段时触发。

In this case , the custom component has already added the onfocus and onblur attributes to the nested components during the processing of a previous request .

在这种情况下，自定义组件已经在处理前一个请求期间将onfocus和onblur属性添加到嵌套组件。

You can use JavaScript to implement control events such as onclick , onchange , and onblur and page events such as afterPageLoad .

可以使用JavaScript来实现控件事件（例如onclick、onchange和onblur）以及页面事件（例如afterPageLoad）。

This can be any client-side JavaScript event , such as onclick for a button , onblur for an input field , or onchange for a check box .

它可以是任何的客户端JavaScript事件，例如按钮的onclick，输入栏的onblur，或复选框的onchange。
