如何限制div jquery或javascript的子代数？

Question

How I can limit display number (ex: 6) child of div jquery or javascript or other method?

 <div class="parent"> <!--START--> <div class="child">Text</div> <div class="child">Text</div> <div class="child">Text</div> <div class="child">Text</div> <div class="child">Text</div> <div class="child">Text</div> <!--END--> <div class="child">Text</div> <div class="child">Text</div> <div class="child">Text</div> <div class="child">Text</div> <div class="child">Text</div> <div class="child">Text</div> </div> 

Answer 1

What you want is the .slice method.

 var divs = $(".parent .child").slice(0, 6); console.log(divs.length); 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <div class="parent"> <!--START--> <div class="child">Text</div> <div class="child">Text</div> <div class="child">Text</div> <div class="child">Text</div> <div class="child">Text</div> <div class="child">Text</div> <!--END--> <div class="child">Text</div> <div class="child">Text</div> <div class="child">Text</div> <div class="child">Text</div> <div class="child">Text</div> <div class="child">Text</div> </div> 

Answer 2

Working Fiddle

It can be done as simply using slice at the point where you want to cut off the elements, and then calling the jquery remove function:

$('.parent .child').slice(0, 6).remove();
