问题描述:

I have inside two div tags a tag named path which I want to hide when I click on the div id toto but not for tata.

Can I do that with JavaScript?

<div id="tata">

</div>

This is the code to add a CSS style to my element:

$("path").css("display", "none");

But the issue now is that I want to add that style only for the path tag which is in div id toto.

NB: the tag named Path doesn't have an id and I can't add it.

网友答案:

The following expression would target the path element during the click handler of the div toto and hide it.

$('#toto').on('click',function()
{
       $(this).find("path").hide();
});

网友答案:

You can select the div that contains the path element that you want and then find the path tag below it.

$('#toto').find('path').css('display', 'none');

https://api.jquery.com/find/

You can also just directly refer to the element:

$('#toto path').css('display', 'none');

But iirc using find() will result in some optimizations for finding the elements in your code.
