我有原始行为的复选框。我想在展开和折叠这些复选框的同时为其添加+和 - 符号。
任何人都可以告诉我如何实现这一目标?
以下是我的玉代码:
.form-group
.checkbox#some-checkbox(style="margin-left: 10px;")
label(data-toggle='collapse', data-target='#collapseOne', aria-expanded='false', aria-controls='collapseOne')
input(type='checkbox')
| My Name
#collapseOne.collapse(aria-expanded='false')
.well1
.row
.col-sm-12.col-lg-12
.nutrition-category
.row.header3.margin-left-10
.row.paragraph
.col-xs-6(style="font-size: 18px;") New Name
非玉(HTML)代码:
<div class="form-group">
<div class="checkbox" id="some-checkbox" style="margin-left: 10px">
<label data-toggle="collapse" data-target="#collapseOne" aria-
expanded="false" aria-controls="collapseOne">
<input type="checkbox"/> My Name
</label>
</div>
</div>
<div class="collapse" id="collapseOne" aria-expanded="false">
<div class="well1">
<div class="row">
<div class="col-sm-12 col-lg-12">
<div class="nutrition-category">
<div class="row header3 margin-left-10">
<div class="row paragraph">
<div class="col-xs-6" style="font-size: 18px"> New
Name</div>
</div>
</div>
</div>
</div>
</div>
这是我用过的javascript:
script(type='text/javascript').
$(document).ready(function() {
$("#some-checkbox").prop("indeterminate", true);
});
