如何在jquery中正确地转义双引号

Question

更新:通过删除逗号之间的空格,我成功地删除了其中一个随机等号/"s.但是,只要字符串中有空格,用户名就会插入"="""返回(firstName lastName).知道为什么会这样做吗？它还在"> join ..."之前插入"=""",这很奇怪,因为那里没有空间......

 $("#ride").append('<div class= "style"><img src = "'
                 + snapshot.val().id
                 + '" style="width:68px;height:68px;"/><p>' 
                 + snapshot.val().user 
                 + '</p><ul class = "styling"><li>'  
                 + snapshot.val().when 
                 + ' '
                 + snapshot.val().from 
                 + ' - ' 
                 + snapshot.val().to 
                 + '</li><li>' 
                 + snapshot.val().comments 
                 + '</li><button type="button" class="btn btn-outline-info" onclick = "initMessenger(\"'  
                 + snapshot.val().user
                 + '\",\"'
                 + snapshot.val().reference 
                 + '\")\">join this ride</button></ul></div>');

我正在使用jquery来编写动态HTML内容.

data.forEach(function(snapshot) {
     $("#ride").append('<div class= "style"><img src = "'
                 + snapshot.val().id
                 + '" style="width:68px;height:68px;"/><p>' 
                 + snapshot.val().user 
                 + '</p><ul class = "styling"><li>'  
                 + snapshot.val().when 
                 + ' '
                 + snapshot.val().from 
                 + ' - ' 
                 + snapshot.val().to 
                 + '</li><li>' 
                 + snapshot.val().comments 
                 + '</li><button type="button" class="btn btn-outline-info" onclick = "initMessenger(\"' 
                 + snapshot.val().user 
                 + '\" , \"'
                 + snapshot.val().reference 
                 + '\")">join this ride</button></ul></div>');
             });

        console.log('ID : ' + $("#ride").html());
});

这些是我的jquery代码创建的div.目前,当我单击此div中的任一按钮时,我收到"Uncaught SyntaxError:Unexpected token}"消息:

   <div class="style"><img src="https://lh3.googleusercontent.com/-XdUIqdMkCWA/AAAAAAAAAAI/AAAAAAAAAAA/4252rscbv5M/photo.jpg" style="width:68px;height:68px;">
    <p>Liz</p>
    <ul class="styling">
        <li>Wed Mar 29 2017 07:00 AM - 09:00 PM</li>
        <li>test 2 </li><button type="button" class="btn btn-outline-info" onclick="initMessenger(" liz="" smith "=" " ,=" " "-kfsqld0eras9ri4v9es ")"="">join this ride</button></ul>
</div>
<div class="style"><img src="https://lh3.googleusercontent.com/-XdUIqdMkCWA/AAAAAAAAAAI/AAAAAAAAAAA/4252rscbv5M/photo.jpg" style="width:68px;height:68px;">
    <p>Liz</p>
    <ul class="styling">
        <li>Thu Mar 23 2017 02:00 AM - 05:30 AM</li>
        <li>TEST THREE</li><button type="button" class="btn btn-outline-info" onclick="initMessenger(" liz="" smith "=" " ,=" " "-kfsvhs6q-x-bdhz8jfk ")"="">join this ride</button></ul>
</div>

为什么我的initMessenger在所有地方调用所有这些随机等号并加上引号？我怎么摆脱他们？

为了避免逃避噩梦,可以使用新的ES6模板文字

像这样

$("#ride").append(`
<div class="style">
    <img src="${snapshot.val().id}" style="width:68px;height:68px;"/>
    <p>${snapshot.val().user}</p>
    <ul class="styling">
    <li>${snapshot.val().when} ${snapshot.val().from} - ${snapshot.val().to}</li>
    <li>snapshot.val().comments</li>
    <button type="button" class="btn btn-outline-info" onclick="initMessenger('${snapshot.val().user}','${snapshot.val().reference}')">join this ride</button>
    </ul>
</div>`);

现在没有必要转义任何字符,例如: onclick="initMessenger('${snapshot.val().user}','${snapshot.val().reference}')"
