使用JavaScript将光标放在文本输入元素中的文本末尾
问题描述：
将焦点设置为元素后，将光标放在输入文本元素中的文本末尾的最佳方法（我假设最简单的方法）是什么？
What is the best way (and I presume simplest way) to place the cursor at the end of the text in a input text element via JavaScript - after focus has been set to the element?
答
我在IE中遇到了同样的问题（在通过RJS / prototype设置焦点之后）。
当字段已有值时，Firefox已将光标留在最后。 IE正在强制光标到文本的开头。
I faced this same issue (after setting focus through RJS/prototype) in IE. Firefox was already leaving the cursor at the end when there is already a value for the field. IE was forcing the cursor to the beginning of the text.
我到达的解决方案如下：
The solution I arrived at is as follows:
<input id="search" type="text" value="mycurrtext" size="30"
onfocus="this.value = this.value;" name="search"/>
这适用于IE7和FF3
This works in both IE7 and FF3
