如何使用 text() 查找元素

Question

I'm wondering if it's possible to hide the parent div based on child text content?

 //$('div >.tree-title').hide();

 <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script> <div class="container"> <span>1</span> <span></span> <span class="tree-title">Hello</span> </div> <div class="container"> <span>2</span> <span></span> <span class="tree-title">World</span> </div>

In this case I would like to hide the second div because the class .tree-title contain World text.

Answer 1

You can use jQuery's :contains() and .parent()

 $('div >.tree-title:contains(World)').parent().hide();

 <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script> <div class="container"> <span>1</span> <span></span> <span class="tree-title">Hello</span> </div> <div class="container"> <span>2</span> <span></span> <span class="tree-title">World</span> </div>

Answer 2

Using contains :

$('div > .tree-title:contains("World")').parent().hide();

Using filter :

$('.tree-title').contents().filter(function(){
  return $(this).text().trim() == 'World';
}).parents('container').hide();

Answer 3

Using :has and :contains Selector

 $('div:has(.tree-title:contains(World))').hide();

 <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script> <div class="container"> <span>1</span> <span></span> <span class="tree-title">Hello</span> </div> <div class="container"> <span>2</span> <span></span> <span class="tree-title">World</span> </div>

Answer 4

You can also:

$('.tree-title').each(function() {
  if($(this).text() === 'World') {
    $(this).parent().hide();
  }
});

Hope it helps:)
