双引号被替换为 &quote;

Question

我的 JavaScript 变量包含一个字符串:

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

但是当我将其显示在HTML组件中时，它看起来像这样：

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

Answer 1

将字符串输出为HTML格式，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>

<strong>Correct with jQuery</strong>
<div id="correct-jquery"></div>

<strong>Incorrect with plain JavaScript</strong>
<div id="incorrect-js"></div>

<strong>Correct with plain JavaScript</strong>
<div id="correct-js"></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);

使用 decodeURI JavaScript 函数来展示示例。

var s= decodeURI('your string');

这不是一个URI；"是一个HTML实体。 - Drew Gaynor
