如何 select div 具有完全特定的文本

Question

In the example below I need 1 as the result because only one title has its text = lorem ipsum
I tried with contains but it counts all variations of a given criteria.

 var str = 'lorem ipsum'; let x = $(`.title:contains("${str}")`).length; console.log(x);

 <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script> <div class='title'>lorem ipsum</div> <div class='title'>lorem ipsum a</div> <div class='title'>a lorem ipsum</div>

Answer 1

You can use .filter on the output of your selector to restrict it to the div that has the exact text contents of lorem ipsum .

 var str = 'lorem ipsum'; let x = $(`.title:contains("${str}")`).filter(function() { return $(this).text() == str; }).length; console.log(x);

 <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script> <div class='title'>lorem ipsum</div> <div class='title'>lorem ipsum a</div> <div class='title'>a lorem ipsum</div>

Note that since you are testing the text value twice, you could just use $('.title') ; dependent on your HTML structure that may be faster.
