Question

I have the following code

var input = $('#el_id');
wrapper = $(document.createElement('div'));
wrapper.addClass('small');
wrapper.css('width',200);
input.wrap(wrapper);

alert(input.children().length)

I get 0 for the children length. What I want is:

<div class="small" style="width: 200px;">
     <input type="text" id="el_id" />
</div>

But I want the small div to be dynamically generated. Any idea why this isn’t working?

UPDATE

It turns out my issue lies on another line of code. I want to assign the wrapper to a variable after I wrap and:

block = input.wrap("<div class='"+container_class+"' style='width: "+wrap_width+"px;'></div>");

does not work. It returns the input which makes sense. But how can I return the wrapper?

Thanks!

Answer 1

I believe you are doing it right.

You just need to save the results of the wrap function to a variable:

Edit: Updated the code to get parent():

var wrapped = input.wrap(wrapper).parent();
alert(wrapped.children().length);
