htmlspecialchars（）期望参数1是字符串，在Laravel中给出的数组

I have got this error in my Laravel blade template

htmlspecialchars() expects parameter 1 to be string, array given

I have tried to convert the array into string in blade template.

Here is the code

<script>
    var value = {{ $sliderImageDataArray }}.toString()
    window.MedicPressSliderCaptions = value;
</script>

Where $silderImageDataArray is the variable and value stored here.

Here is the $silderImageDataArray value

[{"title":"First title","text":"<p><span id=\"hs_cos_wrapper_module_1498510869515998\" class=\"hs_cos_wrapper hs_cos_wrapper_widget_container hs_cos_wrapper_type_widget_container\" data-hs-cos-general-type=\"widget_container\" data-hs-cos-type=\"widget_container\">First title<\\\/span><\\\/p>
<p><a class=\"btn  btn-secondary\" href=\"http:\\\/\\\/localhost\\\/sencare\\\/book-appoinment\\\/\" target=\"_self\">  Make An Appointment <\\\/a>\\u00a0<a class=\"btn  btn-light\" href=\"http:\\\/\\\/localhost\\\/sencare\\\/our-doctors\\\/\" target=\"_self\"> Our Doctors<\\\/a><\\\/p>
","is_video":false},{"title":"Second","text":"<p><span id=\"hs_cos_wrapper_module_1498510869515998\" class=\"hs_cos_wrapper hs_cos_wrapper_widget_container hs_cos_wrapper_type_widget_container\" data-hs-cos-general-type=\"widget_container\" data-hs-cos-type=\"widget_container\">Second<\\\/span><\\\/p>

","is_video":false}]

{{}} will be converted to echo() by Blade template engine. And you're trying to echo the array as a string.

You may convert it to JSON:

var value = '{{ json_encode($sliderImageDataArray) }}';

If it's a Laravel collection or a model:

var value = '{{ $sliderImageData->toJson() }}';
