有没有人可以帮助我?预先感谢！

Is there anyone can help me? Thanks in advance!

我尝试了以下代码，但这是不正确的.

I have tried the following code,however, it's not correct.

var quote_str =  'str';

推荐答案

我认为您想在字符串文字之外使用分号:

I think that you want the semicolon outside the string literal:

var quote_str = '<option value="1">tea</option>';

如果您还希望在字符串中包含撇号字符，则可以使用 \'将撇号放在由撇号分隔的字符串中:

If you mean that you want apostrophe characters inside the string also, you can use \' to put an apostrophe in a string delimited by apostrophes:

var quote_str = '\'<option value="1">tea</option>\'';

您还可以使用引号分隔字符串.然后，您不必转义撇号，但是您必须转义引号:

You can also use quotation marks to delimit the string. Then you don't have to escape the apostrophes, but you have to escape the quotation marks:

var quote_str = "'<option value=\"1\">tea</option>'";

如果您已经有一个字符串，并且想在字符串周围添加撇号，则可以将字符串连接起来:

If you already have a string, and want to add apostrophes around it, you concatenate strings:

var quote_str =  "'" + str + "'";
