JavaScript的集中删除文本高亮显示 [英] Javascript focus remove text highlight

问题描述

我有更新面板输入（文本字段），它的文字每次更改后autopostbacks。我可以保持聚焦在同一个文本字段，但我无法摆脱它调用的document.getElementById（'myTextField将'）之后出现的文本higlight的。重点（）。
这种解决方案似乎是最准确的

I have an input (text field) in update panel, and it autopostbacks after each change of text. I can keep focus on the same text field, but i can't get rid of text higlight which appears after calling document.getElementById('myTextField').focus(). This solution seemed to be the most accurate:

if (window.getSelection) {
    window.getSelection().removeAllRanges();
} else if (document.selection) {
    document.selection.empty();
}

但它有一个问题。输入保持专注，但我不能写的文字。我写之前，点击它。

But it has one problem. Input remains focused, but i can't write text. I have to click on it before writing.
