Rails Javascript haml变量创建

Question

I have Code pasted below for creation of variables in javascript with rails + javascript variables

:javascript
$( ".form-control" ).each(function( index ) {


var mix = $( this ).attr("id").split("_");
var e_array = mix.shift();
var e_name = mix.join("_");

var error = "#{@account.errors[:" + e_name +"]}";

//var error = error[":" + ];
alert(error);



console.log( "#{@account.errors}");
});

Why does the array return empty?

Answer 1

试试这个"#{@account.errors['"+e_name+"']}";
