「行頭に移動」の版間の差分

「shift」変数を「true」に書き換えると、選択しながら移動します。「Shift + Home」キーなどに割り当ててご利用ください。

* kuroさん版以外がうまく動かないようでしたので、sukemaruさんの「[[行頭か行末 または 選択範囲の始点か終点]]」を参考に、トグルなしの移動のみを行う簡易版として書き直してみました。

<syntaxhighlight lang="javascript">

    var d = document, s = d.selection;

    var meP = logic ? mePosLogical : mePosView;

    var meGL = logic ? 0 : meGetLineView;

    Redraw = false;

    var x = s.GetActivePointX( meP );

    var y = s.GetActivePointY( meP );

    var pos = s.GetActivePos(); // 現在位置

    var top = pos + 1 - x;      // 行頭位置

    var st = d.GetLine( y, meGL );

    var sId = st.search( indent );    // 行頭の空白文字数

    var ind = top + sId;    // インデントの後ろ位置

    if ( ind < pos ) {

        // 文字列開始位置に移動（インデントの後ろ）

        s.SetActivePos( ind, shift );

    }

    else {

        // 文頭に移動

        s.StartOfLine( shift, meP );

    }

    Redraw = true;
