Question

我正在使用Bootstrap 3.2。我试图弄清楚是否有办法显示/隐藏“col-sz-＃”div并更改可见div中的“col-sz-＃”类以调整它们以使用复选框样式按钮调整容器每一栏。

例如，如果我以

开头

<div class="row">
    <div class="col-md-2">...</div>
    <div class="col-md-2">...</div>
    <div class="col-md-2">...</div>
    <div class="col-md-2">...</div>
    <div class="col-md-2">...</div>
    <div class="col-md-2">...</div>
</div>

然后如果隐藏其中2个并且其他人调整大小：

<div class="row">
    <div class="col-md-2 hidden">...</div>
    <div class="col-md-2 hidden">...</div>
    <div class="col-md-3">...</div>
    <div class="col-md-3">...</div>
    <div class="col-md-3">...</div>
    <div class="col-md-3">...</div>
</div>

如果总列数不能像5那样均匀地划分12，那么它就不会改变。

Answer 1

你可以这样做：

var $myCols =  $("#myColumns");

$("#toggleColumns input").change(function() {
    var index = +this.value - 1;
    var visible = this.checked;

    $($myCols.children().get(index)).toggle(visible);

    resizeColumns();
});

function resizeColumns() {
    var visibleCols = $myCols.children(":visible").length;

    var div = Math.floor(12 / visibleCols);
    var rem = 12 % visibleCols;

    var colSize = (rem === 0) ? div : 2;

    $myCols.children().removeClass().addClass('col-md-'+colSize);

}

<强>更新：

如果您想对多个相同的行进行操作，只需使用选择器查找所有行并在each行调用函数：

$(".resizeRow").each(function(){
    var $eachRow = $(this);
    // Do Stuff
});

这是我解决问题的方法，是从https://codepen.io/feger/pen/deIki改编而成的。

		$("input:checkbox:not(:checked)").each(function() {
		    var column = "table ." + $(this).attr("name");
		    $(column).hide();
		});

		$("input:checkbox").click(function(){
		    var column = "table ." + $(this).attr("name");
		    $(column).toggle();
		});

		.clearfix:before,.clearfix:after {
		    content: " ";display: table; /* 2 */}
		.clearfix:after {clear: both;}
		.clearfix {*zoom: 1;}

		.options {margin-bottom: 8px;}

		/* Style checkboxes as Toggle Buttons */
		.ck-button {
		    margin:2px;
		    background-color:#EFEFEF;
		    border-radius:4px;
		    border:1px solid #aaa;
		    overflow:auto;
		    float:left;
		    color:#aaa;
		}
		.ck-button:hover {
		    background-color:#ddd;
		}
		.ck-button label {
		    float:left;
		    width:auto;
		    margin-bottom: 0;
		}
		.ck-button label span {
		    text-align:center;
		    padding:3px 8px;
		    display:block;
		}
		.ck-button label input {
		    position:absolute;
		    top:-20px;
		}
		.ck-button input:checked + span {
		    color:#111;
		}

Answer 3

查看此fiddle。在这里，我使用jquery toggle来显示/隐藏元素。我认为，小提琴将是一个很好的起点。你也可以用css（没有jquery）来做这件事。然后，你必须设置 display: none属性。
