我需要这个按钮:
<div class="myButton" id="clearBefore">Click Me</div>
将伪类“:before”中的'content'更改为'text'。
.ms-ChoiceField-input:before{ content:'Old content'; }
/*after button click content changes*/
.ms-ChoiceField-input:before{ content:'New Content'; }
<div class="checkboxHiddenSelectContainer" data-toggle="filterList" style="display: block;">
<div class="ms-ChoiceField">
<input class="ms-ChoiceField-input">
<label class="ms-ChoiceField-field"">
:before
<span class="ms-Label">Function</span>
:after
</label>
</div>
</div>

您似乎在HTML中使用了伪类,它不应该具有伪类的效果。你应该在你的CSS中使用它们:
.ms-Label:before {
content: "I am before";
}
就切换而言,如果我理解正确,您可以通过向标签添加课程toggle
并将之前的选择器更改为.ms-Label.toggled:before
来实现这一目标
