我希望在折叠顶部面板时将底部面板的宽度扩展到col-md-12
,并且当用户再次扩展顶部面板时,底部面板的宽度又回到col-md-8
。
我对此很陌生,但这是到目前为止的代码:
var panel = document.getElementById("panel");
var panel1 = document.getElementById("panel1");
function secondPanelResize() {
if (panel.style.height <= "45") {
panel1.classList.remove("col-md-8");
panel1.classList.add("col-md-12");
} else {
panel1.classList.remove("col-md-12");
panel1.classList.add("col-md-8");
}
}
<div class="panel-group col-md-12">
<div class="col-md-8" id="panel">
<div class="panel panel-default">
<div class="panel-heading">
<h4 class="panel-title">
<a data-toggle="collapse" href="#collapse1" onclick="secondPanelResize()" id="collapse">Collapsible panel</a>
</h4>
</div>
<div id="collapse1" class="panel-collapse collapse in">
<div class="panel-body" id="panelbody">Panel Body</div>
</div>
</div>
</div>
<div class="col-md-8" id="panel1">
<div class="panel panel-default">
<div class="panel-heading">
<h4 class="panel-title">
<a data-toggle="collapse" href="#collapse2">Collapsible panel</a>
</h4>
</div>
<div id="collapse2" class="panel-collapse collapse in">
<div class="panel-body" id="panelBody">Panel Body</div>
</div>
</div>
</div>
</div>
我设法使顶板关闭时扩大其宽度,但是我不知道如何在顶板打开时减小其宽度。

这是使用JS添加和删除CSS类的基本示例。
style="width: 0px;"
function topPanel() {
var topPanelEle = document.getElementById('topPanel')
var bottomPanelEle = document.getElementById('bottomPanel')
if (!topPanelEle.classList.contains('expanded')) { //To aviod multiple clicks
topPanelEle.classList.add('expanded');
}
bottomPanelEle.classList.remove('expanded');
}
function bottomPanel() {
var topPanelEle = document.getElementById('topPanel')
var bottomPanelEle = document.getElementById('bottomPanel')
if (!bottomPanelEle.classList.contains('expanded')) { //To aviod multiple clicks
bottomPanelEle.classList.add('expanded');
}
topPanelEle.classList.remove('expanded');
}
.top-panel {
padding: 16px;
background-color: red;
}
.bottom-panel {
padding: 16px;
background-color: blue;
}
.expanded {
height: 100px;
}
现在,对于您的情况,我不确定,因为没有给出CSS,但是在您添加的类(例如<a href="javascript:topPanel()">Expand Top Panel</a>
<div id="topPanel" class="top-panel">Top Panel</div>
<a href="javascript:bottomPanel()">Expand Top Panel</a>
<div id="bottomPanel" class="bottom-panel">Bottom Panel</div>
)中可以包含expanded
并覆盖添加的默认CSS (例如height: 100% !important
或top-panel
),可能类似于bottom-panel
。我还发现使用2个函数或将1个参数用作参数会更容易,因此,除非您有1个按钮作为切换按钮,否则我知道它是从顶部还是底部从其直接调用。
