为什么当我使用Vue.js时搜索不起作用？

Question

I'm making a simple search engine for my Laravel 5 app. As it's only small, I'm just using a FULLTEXT index on my main table. I'm trying to use Vue.js to avoid a page reload.

In my SearchController I simply have:

public function search(Request $request)
    {
        $search = $request->search;

        $results = Product::whereRaw("MATCH (product_name, product_description) AGAINST (? IN BOOLEAN MODE)", array($search))->get(array('product_name','slug'));

        return $results;
    }

Javascript:

getResults: function(e){
        e.preventDefault();
        this.$http.get('api/search', function(search){
            this.$set('searchResults', search);
        });
}

and the form:

{!! Form::open(['v-on' => 'submit: getResults($event)', 'method' => 'get', 'action' => 'SearchController@search']) !!}
        <div class="form-group">
            {!! Form::label('search','Search:') !!}
            {!! Form::text('search', null, ['class' => 'form-control', 'v-model' => 'search']) !!}
        </div>

        <div class="form-group">
            {!! Form::submit('Submit', ['class' => 'form-control btn btn-primary']) !!}
        </div>

{!! Form::close() !!}

If I remove Vue.js from the equation, the form submits and I get a nice JSON object of search results. If I put it through Vue.js, I just get an empty object. I'm using the same search term in both cases.

What am I doing wrong?

EDIT: I've logged search to the console in my getResults function, and it's empty, which explains things a little. But why is it empty? If I echo out the data search is populated as I type by Vue's 2-way binding, so search definitely is not empty...

It's because you don't send anything with vueJS. No data are sent with the ajax request. You need to do something like that.

this.$http.get('api/search', this.search , function(search){
        this.$set('searchResults', search);
    });
