在文本框内切换 [英] Tabbing inside Textbox

问题描述

大家好

当我在多行文本框中书写内容并按Tab键时，它将转到下一个控件，但我想将4个字符移动到其他控件中.

请帮我做这个

我在Google中进行搜索，并在Windows应用程序的文本框中获得了"AcceptsTab"属性，该属性将在文本框中启用和可拨号的制表符.

但没有在Web应用程序中获得此属性..

如何在Web应用程序中实现(使用javascript或服务器端).
(我不是想在一个文本框中实现所有功能)


请帮忙
在此先感谢

推荐答案

尝试一下

function bindTabbing(event)
{
    if (event.which || event.keyCode)
    {
        // 9 indicates TAB key.
        if ((event.which == 9) || (event.keyCode == 9))
        {
            var subject = document.getElementById(txtProgramEditor); // Get the Editor textarea control.
            if (event.srcElement == subject) // If tab is pressed in the textarea then do the action.
            {
                // Creates a range and adds the Tab equivalent character in the text range.
                subject.selection = document.selection.createRange();
                subject.selection.text = String.fromCharCode(9);
                event.returnValue = false;
            }

            if (subject.selectionStart || subject.selectionStart == '0')
            {
                var str = subject.value;
                var startIndex = subject.selectionStart;
                subject.value = str.substring(0, startIndex) + '    ' + str.substring(startIndex, str.length);
                subject.focus();
                subject.selectionEnd = startIndex + 4;
                return false;
            }
        }
    }
    else
    {
        return true;
    }
}

尝试一下..

Try this..

(' #textboxid' span>).live(' keydown'，function(e){ var keyCode = e.keyCode || e.哪个; var s =

('#textboxid').live('keydown', function(e) { var keyCode = e.keyCode || e.which; var s=
