Json数据出错:Laravel 5.1

Question

这是什么意思？

我在数组中添加元素,最后尝试将该数组转换为Json.下面是代码.

$SubCategoryList = array();

array_push($SubCategoryList, 
            array(
                'SubCategoryID' =>  1,
                'FirstName'   =>  'First Name',
                'LastName'    =>  'Last Name',
            ));
array_push($SubCategoryList, 
            array(
                'SubCategoryID' =>  2,
                'FirstName'   =>  'First Name2',
                'LastName'    =>  'Last Name2',
            ));

以上给出了下面提到的输出

Array
(
    [0] => Array
        (
            [SubCategoryID] => 1
            [FirstName] => First Name
            [LastName] => Last Name
        )

    [1] => Array
        (
            [SubCategoryID] => 2
            [FirstName] => First Name2
            [LastName] => Last Name2
        )

)

下面是用于将数组转换为Json的代码.

<script>
     var subCategoriesList = {{ json_encode($SubCategoryList) }};
</script>

最后json给出了以下输出.这可以在View source中看到

var subCategoriesList = [{"SubCategoryID":1,"FirstName":
"First Name","LastName":"Last Name"},
{"SubCategoryID":2,"FirstName":"First Name2",
"LastName":"Last Name2"}];

题

为什么它给出了"在json数据中？

Answer 1

JSON字符串使用引号显示值以基本术语开始和结束的位置.

给

 var subCategoriesList = {!! $SubCategoryList !!};

一个去.这将为json回显未转义的字符串.
