的jQuery

</div>

预期输出

<div id="date_filter_si">
    <input type="radio" class="date_action" name="date_action" value="Y" checked=""> 
    <input type="radio" class="date_action" name="date_action" value="W" checked=""> 
</div>

$( "#date_filter_si:contains('Weekly')" ).remove();

Answer 1

您可以过滤文本节点（element.nodeType == 3）然后删除。

＆＃13;

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="date_filter_si">  
    <input type="radio" class="date_action" name="date_action" value="Y" checked="" onclick="set_date_filter('Y')"> year
    <input type="radio" class="date_action" name="date_action" value="W" checked="" onclick="set_date_filter('W')"> Weekly
</div>

＆＃13;

'/user'

＆＃13;

Answer 2

您可以使用Node.nextSibling属性更改元素的下一个兄弟文本。

$("#date_filter_si > input")[0].nextSibling.textContent = "";

$("#date_filter_si > input")[0].nextSibling.textContent = "";

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="date_filter_si">
  <input type="radio" class="date_action"> year
</div>

如果你有多个输入和兄弟文本，请使用：

$("#date_filter_si > input").each(function(){
    this.nextSibling.textContent = "";
});

$("#date_filter_si > input").each(function(){
  this.nextSibling.textContent = "";
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="date_filter_si">
  <input type="radio" class="date_action"> year
  <input type="radio" class="date_action"> week
</div>

Answer 3

我就是这样做的。

$( "#date_filter_si:contains('Weekly') input" ).each(function(){
  var el = this.nextSibling;
  if(el && el.nodeType === Node.TEXT_NODE) {
    el.parentNode.removeChild(el);
  }
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

<div id="date_filter_si">
    <input type="radio" class="date_action" name="date_action" value="Y" checked="" onclick="set_date_filter('Y')"> year
    <input type="radio" class="date_action" name="date_action" value="W" checked="" onclick="set_date_filter('W')"> Weekly
</div>
