单击范围时，Javascript自隐藏父div不隐藏

Question

I have a div that's been created dynamically. Multiple of them are created and I need to do a self parent hide, so this is what I've done:

This Div:

<div><a href="">'+inputText+'-</a><div class="box"></div><span onclick="dismiss();">Close</span></div>

The Function:

function dismiss() {
    $(this).parents('div').fadeOut();
}

It's not hidding when I click the close span.

Answer 1

Inside dismiss function this refers to window object, instead pass the this as an argument .

 function dismiss(ele) { $(ele).parents('div').fadeOut(); console.log(this); } 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script> <div><a href="">'+inputText+'-</a> <div class="box"></div><span onclick="dismiss.bind(this);dismiss(this);">Close</span> </div> 

Answer 2

You can not access $(this) directly into any function:

So: pass this as parameter:

<span onclick="dismiss(this);">Close</span>

function dismiss(obj) {
    $(obj).parents('div').fadeOut();
}

Answer 3

Instead of using a span for this, consider using a button. It would be semantically appropriate. Maybe even change the <div> to a <p> (depending on if it is a paragraph or not). Keep in mind that you can't have a div inside ap though, so you would need to change the .box div to a span.

<div>
    <a href="">'+inputText+'-</a>
    <div class="box"></div>
    <button onclick="dismiss(this);">Close</button>
</div>

And for the JS:

function dismiss(obj) {
$(obj).parents('div').fadeOut();
return false;
}

Answer 4

Another way, change the html

<div>
  <a href="">Click</a>
  <div class="box"></div>
  <span id="btn">Close</span>
</div>

And JS

$(document).on('click','#btn', function(){
  $(this).parents('div').hide();
});
