Uncaught SyntaxError: Unexpected token & in javascript django app

This is my function:

function convert_strings() {
var chart_labels = {{ chartlabels }};
var array_length = chart_labels.length;
for (var i = 0; i < array_length; i++) {
    chart_labels[i] = chart_labels[i].replace(/&#039;/g, "'")
    }
return chart_labels
}

This is my error: "Uncaught SyntaxError: Unexpected token &"

function convert_strings() {
var chart_labels = [&#39;CHENNAI LPG RO&#39;, &#39;KOCHI LPG RO&#39;, &#39;BANGALORE LPG RO&#39;, &#39;HUBLI LPG RO&#39;, &#39;MADURAI LPG RO&#39;, &#39;MANGLORE LPG RO&#39;];
var array_length = chart_labels.length;
for (var i = 0; i < array_length; i++) {
    chart_labels[i] = chart_labels[i].replace(/&#039;/g, "'")
    }
return chart_labels
}

Please advice what to do :)

{{ chart_labels|safe }}

This would do it. No need to use .replace or jsonDump

In the view, you can convert the chartlabels to a JSON blob, for example with:

import json

def some_view(request):
    # ...
    context['chartlabels_json'] = json.dumps(context['chartlabels'])
    # ...
    return render(request, 'some_template.html', context)

In the template, we can then write the blob in an unescaped way:

function convert_strings() {
    return {{ chartlabels_json|safe }};
}

A more convenient way is however probably using the django-jsonify [PyPI] tool, and thus simply pass the charlabel through the jsonify filter.

Use the following, for more details on creating the regex for special characters follows this links javascript regex for special characters:

var str = '&#39;CHENNAI LPG RO&#39;'
console.log(str.replace(/\&\#39;/g, "'"));
