在 JavaScript 中为变量字符串加上引号

Question

I have a JavaScript variable:

var text = "http://example.com"

Text can be multiple links. How can I put '' around the variable string?

I want the strings to, for example, look like this:

"'http://example.com'"

Answer 1

var text = "\"http://example.com\""; 

无论你的文字是什么，要用"包装它，你需要把它们放在里面并用\转义。上面将导致：

"http://example.com"

Answer 2

var text = "http://example.com";

text = "'"+text+"'";

Would attach the single quotes (') to the front and the back of the string.

Answer 3

我认为，对您来说，将价值放在引号内的最好和最简单的方法是：

JSON.stringify(variable or value)

Answer 4

You can add these single quotes with template literals:

 var text = "http://example.com" var quoteText = `'${text}'` console.log(quoteText)

Docs are here . Browsers that support template literals listed here .

Answer 5

尝试：

var text = "'" + "http://example.com" + "'";

Answer 6

To represent the text below in JavaScript:

"'http://example.com'"

Use:

"\"'http://example.com'\""

Or:

'"\'http://example.com\'"'

Note that: We always need to escape the quote that we are surrounding the string with using \

General Pointers:

• You can use quotes inside a string, as long as they don't match the quotes surrounding the string:

Example

var answer="It's alright";
var answer="He is called 'Johnny'";
var answer='He is called "Johnny"';

• Or you can put quotes inside a string by using the \ escape character:

Example

var answer='It\'s alright';
var answer="He is called \"Johnny\"";

• Or you can use a combination of both as shown on top.

Answer 7

In case of array like

result = [ '2015',  '2014',  '2013',  '2011' ],

it gets tricky if you are using escape sequence like:

result = [ \'2015\',  \'2014\',  \'2013\',  \'2011\' ].

Instead, good way to do it is to wrap the array with single quotes as follows:

result = "'"+result+"'";

Answer 8

let's think urls = "http://example1.com http://example2.com "

function somefunction(urls){
var urlarray = urls.split(" ");
var text = "\"'" + urlarray[0] + "'\"";
}

output will be text = "'http://example1.com'"

Answer 9

You can escape " with \

var text="\"word\"";

Answer 10

var text = "\"http://www.example1.com\"; \"http://www.example2.com\"";

Using escape sequence of " (quote), you can achieve this

You can place singe quote (') inside double quotes without any issues Like this

var text = "'http://www.ex.com';'http://www.ex2.com'"

Answer 11

Lets assume you have a bunch of urls separated by spaces. In this case, you could do this:

function quote(text) {
  var urls = text.split(/ /)
  for (var i = 0; i < urls.length; i++) urls[i] = "'" + urls[i] + "'"
  return urls.join(" ")
}

This function takes a string like "http://example.com http://blarg.test" and returns a string like "'http://example.com' 'http://blarg.test'" .

It works very simply: it takes your string of urls, splits it by spaces, surrounds each resulting url with quotes and finally combines all of them back with spaces.

Answer 12

Another easy way to wrap a string is to extend the Javascript String prototype:

String.prototype.quote = function() { return "\"" + this + "\""; };

Use it like this:

var s = "abc";
console.log( "unwrapped: " + s + ", wrapped: " + s.quote() );

and you will see:

unwrapped: abc, wrapped: "abc"

Answer 13

This can be one of several solutions:

var text = "http://example.com";

JSON.stringify(text).replace('\"', '\"\'').replace(/.$/, '\'"')
