我如何只搜索b标签,而不是整个div。 现在我可以搜索整个div,但我只想搜索b标签中的标题。如果列表中有名称,则必须将其删除 HTML:
<div class="row">
<div class="col-md-3">
<div class="panel panel-default" id="list">
<div class="panel-header">
<div class="input-group">
<input type="text" class="form-control" placeholder="Search for users" id="searchName"/>
<div class="input-group-btn">
<div class="btn-group">
<button type="button" class="btn btn-primary">
<span class="glyphicon glyphicon-search"></span></button>
</div>
</div>
</div>
</div>
<div class="panel-body" id="user1">
<div class="row">
<div class="col-md-4">
<img src="" class="img-thumbnail">
</div>
<div class="col-md-8">
<b>Pieter</b><br>

<i>12:01</i>
</div>
</div>
</div>
<div class="panel-body" id="user2">
<div class="row">
<div class="col-md-4">
<img src="" class="img-thumbnail">
</div>
<div class="col-md-8">
<b>Karel</b><br>

<i>11:15</i>
</div>
</div>
</div>
<div class="panel-body" id="user3">
<div class="row">
<div class="col-md-4">
<img src="" class="img-thumbnail">
</div>
<div class="col-md-8">
<b>Pilot</b><br>
(Laatste bericht)<br>
<i>9:36</i>
</div>
</div>
</div>
</div>
</div>
Javascript:
function contains(text_one, text_two){
if (text_one.indexOf(text_two) != -1){
return true;
}
}
$("#searchName").keyup(function () {
var searchName = $("#searchName").val().toLowerCase();
$(".panel-body").each(function () {
if(!contains($(this).text().toLowerCase(), searchName)) {
$(this).hide();
}
else {
$(this).show();
}
});
});
答案 0 :(得分:2)
在条件中使用find()
专注于元素的子B标记:
在:
if(!contains($(this).text().toLowerCase(), searchName)) {
后:
if(!contains($(this).find('b').text().toLowerCase(), searchName)) {
