Safari 和 Chrome 浏览器的对象焦点问题 [英] Object Focus problem with Safari and Chrome browsers

问题描述

我有以下 javascript 被调用以在页面加载时请求焦点.

I have the following javascript being called to request a focus when page is loaded.

此代码在 Firefox 和 IE7 上 100% 正常工作，但 Chrome 和 Safari 似乎根本没有移动焦点.如何使其适用于所有浏览器?

This code works 100% OK with Firefox and IE7, but Chrome and Safari do not seem to move the focus at all. How to make it work with all browsers?

 document.getElementById("MyFlashFile").focus();

推荐答案

确保在呈现整个页面后调用此代码.它可能在它所引用的 HTML 之上被调用，因此该元素尚不存在.

Ensure this code is being called after the entire page has been rendered. It's probably being called above the HTML it refers to, so the element will not exist yet.

各种 JavaScript 框架都有实用程序来告诉您 DOM 何时准备好.

Various JavaScript frameworks have utilities to tell you when the DOM is ready.
