如何在歌剧的文本框上的所需索引中设置焦点 [英] how to set focus in required index on textbox for opera

问题描述

我有一个文本框，需要在文本框的所需索引处设置焦点/光标 在Opera浏览器中.

i'm having a textbox where i need to set focus/ cursor at required index of the textbox in opera browser.

推荐答案

我们的代码可以正常工作，但在歌剧中会发生冲突.

ur code works fine, but getting clash in opera.

becoz以下代码段

becoz the following code snippet

if(elem.createTextRange) {

对于歌剧也是如此，但是createTextRange仅受IE支持.

is also true to opera, but createTextRange 'll only supported by IE.

所以我对您的代码所做的修改很少

So i have changed little modification in ur code

function SetCaretPosition(elemId, caretPos) {
    var elem = document.getElementById(elemId);

    if (elem != null) {
        if ($.browser.msie) {
            if (elem.createTextRange) {
                var range = elem.createTextRange();
                range.move('character', caretPos);
                range.select();
            }
        }
        else {
            if (elem.selectionStart) {
                elem.focus();
                elem.setSelectionRange(caretPos, caretPos);
            }
            else
                elem.focus();
        }
    }
}
