如何在javascript中放置laravel echo函数

Question

How to use echo in strings in javascript datatable

className:'text-center', 
data:'stage', 
name:'stage',
render: function(data)
{
    return '<td class="text-center">{{trans('stage.'' + data.stage + ')}}</td>';
}

error: syntax error, unexpected ''+ data.stage +'' (T_CONSTANT_ENCAPSED_STRING), expecting ',' or ')'

I have tried escaping using backlash it still doesnt look right.

<td class="text-center">{{trans('stage.'.$sub->stage)}}</td> 
//this is what i want to display if i were to use laravel blade

Answer 1

Blade is rendered before you hit the page. So you cannot do what you're trying to, like this. I would recommend using xDebug to see how this works more consistently

If you want to include a translated variant of text in the variable stage , you either need to fetch some HTML and pass it back rendered, via an ajax request for example

OR

You can write/use a javaScript helper which will translate text for you.

OR (best)

You can write an accessor/getter on stage which will translate it before it's received by your DataTable

This would mean writing the following on the Model where the attribute stage comes from. Please note, prefixed Method name with 'get' and 'Attribute' as the suffix.

    public function getStageAttribute()
    {
        return trans($this->stage);
    }
