将字符串输出为HTML而不是纯文本，以便正确呈现HTML实体"。

var s = "{"start":{"lat":19.0759842,"lng":72.87765630000001},"end":{"lat":18.5206624,"lng":73.8567415},"waypoints":[[18.8753235,73.52948409999999]]}";

//Incorrect with jQuery
$("#incorrect-jquery").text(s);

//Correct with jQuery
$("#correct-jquery").html(s);

//Incorrect with plain JavaScript
document.getElementById("incorrect-js").textContent = s;

//Correct with plain JavaScript
document.getElementById("correct-js").innerHTML = s;

div {
  margin-bottom: 20px;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

<strong>Incorrect with jQuery</strong>
<div id="incorrect-jquery"></div>

var text1 = '{"start":{"lat":19.0759842,"lng":72.87765630000001},"end":{"lat":18.5206624,"lng":73.8567415},"waypoints":[[18.8753235,73.52948409999999]]}';
var text2 = text1.replace(/"/g, '\"');

alert('Your data\n' + text1);

alert('Required data\n' + text2);

如果你正在尝试在laravel中view blade中显示json数据，那么你可以尝试这样做<php echo $data？> or @php echo $data;@endphp而不是{{ $data }}

使用decodeURI javascript函数来显示示例

var s= decodeURI('your string');
