在FTL中将JavaScript变量发送到我的模型

Question

I have a list of checkboxes, with this function i get my array of checked items:

 var selected = new Array(); 
 $('#bloqCountries input:checked').each(function() { selected.push($(this).val()); });

I have a model class and i need to send by parameter this array making something like this:

 [#assign searchResults =model.searchContent(selected) /]

But Javascript is in client side and Freemarker in server side...

Then i don´t know how to get this array in my model to call my modelClass..

My idea is making by the request, transforming the array in string and making a split() method in java to delete the "-" between the words

I don't know how to send this content because i´m not using ajax and I don't think its necessary.

Answer 1

Simply put, you can't do that. FTL template is executed on the server and only once, to produce HTML and to send it to browser. JS is executed only when browser receives and processes said HTML. By that time, FTL process is long dead.

If you want to communicate with the server, ajax is the only way to do that. You might find some inspiration and examples of using ajax w/ Magnolia at here or here .
