Javascript，无法读取JSON格式的字符串

Question

I'm trying to pass my variable like this, but it doesn't work, and gives me this error

Uncaught SyntaxError: Invalid or unexpected token"

What's wrong ?

Example:

var arr = "\'id\':1";
alert(arr);

I forgot something, after that, code. I have render my HTML in JavaScript so like this:

row += "<a href='javascript:void(0)' class='btn btn-sm btn-square btn-outline-info' type='buttond' onclick='edit(\""+arr+"\")'><i class='fa fa-pencil'></i></a>";

I get an error after i click that.

Thanks again

Answer 1

Simply try onclick='edit(arr)'

 var row = ''; var arr = "\\'id\\':1"; row += "<a href='javascript:void(0)' class='btn btn-sm btn-square btn-outline-info' type='buttond' onclick='edit(arr)'><i class='fa fa-pencil'></i>Test</a>"; document.body.insertAdjacentHTML('beforeend', row); function edit(a){ alert(a) } 

Answer 2

you can try

"<a href='javascript:void(0)' class='btn btn-sm btn-square btn-outline-info' type='buttond' onclick='edit("+arr+")'><i class='fa fa-pencil'></i></a>"

improtant => onclick='edit("+arr+")'

Answer 3

 const arr = '\\\\\\'id\\\\\\':1'; const row = `<a href="javascript:void(0)" class="btn btn-sm btn-square btn-outline-info" type="buttond" onclick="edit(${arr})"><i class="fa fa-pencil"></i></a>`; console.log(row)
