我有一个名为“workArea”的画布,它比视口大得多并且可拖动。我不认为这是相关的,但把它扔在那里。我正在使用下面的 init 函数动态创建带有淘汰赛的元素。它应该在最后一个元素的右侧和向下 25 像素处创建每个连续元素(技术上是选定的元素,但最后创建的元素会自动被选中)。locy 变量似乎按预期设置并递增,通过 25,但 locx 变量每次都呈指数级增长。我一定错过了一些愚蠢的东西。

Javascript:

ko.bindingHandlers.Item = {
    init: function (element, valueAccessor, allBindingsAccessor, viewModel, bindingContext) {
    var $element = $(element);
    var locx;
    var locy;
    var $pos = $('.itemView.focused').position();
    var $work = $('#workArea');
    if ($('.itemView.focused').length > 0) {
        locx = $pos.left;
        locy = $pos.top;
        console.log('focused element "' + $('.itemView.focused').attr('name') + '" is at ' + locx + ',' + locy)
    } else {
        locx = $work.width() / 2;
        locy = $work.height() / 2;
        console.log('No focused elements, creating at ' + locx + ',' + locy)
    }
    $element.draggable({ ...draggable options here...});
    locx += 25;
    locy += 25;
    $element.css('left', locx.toString() + 'px').css('top', locy.toString() + 'px');
    console.log('Created new element at ' + locx + ',' + locy)
    }
};

这是控制台日志,它与它们在 UI 上的显示位置相匹配

发现了问题...在我忘记的 CSS 类上应用了流氓“float:left”样式。

它现在工作得很好。

我会投票关闭“过于本地化”,但这似乎是很奇怪的行为,所以也许它可以帮助某人?如果有人投票关闭,我不会被冒犯。
