我正在尝试找出此脚本在某些设备上失败的原因。它可以在 Firefox、Chrome 甚至 IE 浏览器中正常工作，但不能在 Safari IOS 中正常工作。

我在这里使用 iPad 通过 JS Fiddle 测试结果: Example »

HTML 取自 UAT 站点，因此有点粗犷，但我已将其略微缩减。以及从原来的 1000 行中剥离出来的脚本。

用于列计算的 JavaScript:

 $.fn.manageColumns = function () {
    function isVisible () {
        return $(this).css("display") !== "none";
    }
    try {
        var $that = $(this);
        var $parent = $that.closest("form");
        var data = $parent.data("state");
        if (! $.isPlainObject(data)) { data = $parent.attr("data-state"); }
        if (! $.isPlainObject(data)) { throw new TypeError("data-state not an object"); }
        console.log(typeof data);
        if ($.isPlainObject(data)) {
            var groups = data.groups;
            var groupString = "";
            $.each(groups, function (key, value) {
                groupString += "[data-column-group=\"" + value + "\"],";
            });
            if (groupString.length) {
                groupString = groupString.slice(0, -1);
            }
            console.log(groupString);
            var $visible = $that.find(groupString).not(".column-vis");
            var $hidden = $that.find("[data-column-group]").not(".column-vis").not($visible);
            var $all = $that.find("[data-column-all]").not(".column-vis");
            $all.hide();
            $visible.show();
            if ($parent.width() < $that.width()) {
                console.log("Will hide columns to fit screen size");
                var maxIterations = 100;
                var minGroups = 1;
                var group = Number.MAX_VALUE;
                for ( ; ($parent.width() < $that.width()) && (maxIterations > 0) &&
                        (group > minGroups); --maxIterations) {
                    var $nextElem = $that.find("col").filter(isVisible).last();
                    group = parseInt($nextElem.data("column-group"));
                    $that.find("[data-column-group=\"" + group + "\"]").not(".column-vis").hide();
                }
                var span = 0;
                $that.find("col").each(function () {
                    var $vCol = $(this);
                    if ($vCol.isVisible()) {
                        var columnSpan = parseInt($vCol.attr("span"));
                        if (columnSpan <= 0) {
                            columnSpan = 1;
                        }
                        span += parseInt(columnSpan);
                    }
                });
                $all.attr("colspan", span).show();
            }
            else {
                console.log("Don't need to hide columns");
                $all.show();
                $hidden.hide();
                $visible.show();
            }
        }
    }
    catch (e) {
        console.log(e.message);
    }
};

如果您在 JS Fiddle 示例中展开窗口，您将看到根据屏幕宽度隐藏和显示的列。

我知道它的边缘有点粗糙，但我们将不胜感激。

最佳答案

bootstrap 将 100% 分配为表格宽度和表格最大宽度，因此在 Safari 中您的 if ($parent.width() < $that.width())不起作用，因为 that table 和 window 一样大，而不是更多。

只需添加

.table {
    width: intrinsic;
    max-width:intrinsic;
}

到你的CSS，你就完成了
