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
关于javascript - 基于宽度计算的表格列显示和隐藏在 Safari IOS 设备中不起作用，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/35918324/
