我有以下HTML代码:
<div>
<div class="firstclass secondclass">
<intro><p>This is the first intro...</p></intro>
<p><button>Button 1</button></p>
<p>This is the first text paragraph</p>
<intro><p>This is the second intro...</p></intro>
<button>Button 2</button>
<p>This is the second text paragraph</p>
This is another text paragraph, but without the <p> element
</div>
</div
我想以下输出usind jQuery:
This is the first intro...
Button 1
This is the second intro...Button 2
我正在尝试这段代码:
$('div.item_desc.custom_content :not(intro, button)').hide()
我得到的是:
This is another text paragraph, but without the <p> element
我正在使用自定义intro-tag进行进一步处理。请注意,button-element一次位于p元素内,另一次不在p元素内。此外,文本的一部分不在p元素中,但我也希望隐藏此文本。我定义需要使用hide命令(因为进一步的限制)。我如何修改我的jQuery代码?
答案 0 :(得分:0)
未测试:
$('div.item_desc.custom_content').children("intro:not(:first), p:not(:eq(0)), p:not(:eq(1))")
但是,更简单的解决方案是创建一个类alwaysshown
<div>
<div class="firstclass secondclass">
<intro class="alwaysshown"><p>This is the first intro...</p></intro>
<p class="alwaysshown"><button>Button 1</button></p>
<p class="alwaysshown">This is the first text paragraph</p>
<intro><p>This is the second intro...</p></intro>
<button>Button 2</button>
<p>This is the second text paragraph</p>
This is another text paragraph, but without the <p> element
</div>
</div>
然后:
$('div.item_desc.custom_content').children(":not("alwaysshown")")

<!DOCTYPE html>
$(document).ready(function(){
var htmlString = $(".firstclass").html();
var data=''; var getthis='';
$(".firstclass").find(":button, intro").each(function () {
var getthis = $( this ).html();
data += getthis;
});
$(".firstclass").html( data );
});

这是第一个介绍...
按钮1
这是第一段文字
这是第二个介绍...
按钮2这是第二段文字
这是另一个文本段落,但没有元素
经过测试的代码工作正常希望它有所帮助。
