页面加载前在Codeigniter中进行DOM操作

Question

is there a way to modify the html of a view file before or as it is loaded, such that a containing div element can be wrapped around existing elements that have a particular class.

So as an example:

if i have the element

<div class="add-wrapper-to-this-elem">

</div>

somewhere within the view file test_view.php, when i load the view via $this->load->view('test_view'); i would then like the view to load with an extra wrapper div around all elements with the class of add-wrapper-to-elem

is this possible and how would i go about it?

Answer 1

You can create a wrapper view file with content and load this view instead:

<div class="add-wrapper-to-this-elem">
          <?php $this->load->view('test_view');?>
</div> 

Answer 2

See Processing Output on the CodeIgniter docs.

You can use the _output function to get rendered HTML in your controller and then use matching (regex or otherwise) to find your elements and wrap them.
