I think that you want the semicolon outside the string literal:
var quote_str = '<option value="1">tea</option>';
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>\'';
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>'";
If you already have a string, and want to add apostrophes around it, you concatenate strings:
var quote_str = "'" + str + "'";

Escape each single quote with a back-slash:
var quote_str = '\'<option value="1">tea</option>;\''
…or wrap the string in quotes of a different kind (i.e. double quotes), but be sure to escape the inner double quotes as to not unintentionally close the string:
var quote_str = "'<option value=\"1\">tea</option>;'"
late update: now we have template literals, so the whole thing becomes a breeze:
var quote_str = `'<option value="1">tea</option>;'`
You can concatenate the variable with your quotes like :
function addQuotes(value){
var quotedVar = "\'" + value + "\'";
return quotedVar;
}
And use it like :
var king = addQuotes('king');
console.log will display :
'king'
Edit : you can try it in the chrome/firefox console, I did it and it works perfectly when copy/paste from here.
var x = 'abc';
var sData = "\'" + x +"\'";
// sData will print "'abc'"
Try this:
document.getElementById("img").innerHTML = '<img src="/sitepath/' + imgg + '.jpg" width="72" height="44" onclick="alert(\'hello\');" />';
If you use apostrophes as delimiter for the HTML attributes, you have to HTML encode the apostrophes that you put inside the attribute:
document.getElementById("img").innerHTML="< img src='/sitepath/"+imgg+".jpg' width='72' height='44' onclick='alert('hello');' />";
I prefer using apostrophes as string delimited in Javascript and quotation marks as delimiters for HTML attributes. Then you just escape the apostrophes that you have inside the Javascript string:
document.getElementById("img").innerHTML='< img src="/sitepath/'+imgg+'.jpg" width="72" height="44" onclick="alert(\'hello\');" />';
To put any string inside a Javascript, inside an HTML attribute, inside a string in Javascript, you do:
- escape any string delimiters in the string
- HTML encode the Javascript code
- escape any string delimiters in the HTML string
You should always consider what the browser will see by the end. In this case, it will see this:
<img src='something' onmouseover='change(' ex1')' />
In other words, the "onmouseover" attribute is just change(, and there's another "attribute" called ex1')' with no value.
The truth is, HTML does not use \ for an escape character. But it does recognise " and ' as escaped quote and apostrophe, respectively.
Armed with this knowledge, use this:
document.getElementById("something").innerHTML = "<img src='something' onmouseover='change("ex1")' />";
... That being said, you could just use JavaScript quotes:
document.getElementById("something").innerHTML = "<img src='something' onmouseover='change(\"ex1\")' />";
The answer here is very simple:
You're already containing it in double quotes, so there's no need to escape it with \.
If you want to escape single quotes in a single quote string:
var string = 'this isn\'t a double quoted string';
var string = "this isn\"t a single quoted string";
// ^ ^ same types, hence we need to escape it with a backslash
or if you want to escape \', you can escape the bashslash to \\ and the quote to \' like so:
var string = 'this isn\\\'t a double quoted string';
// vvvv
// \ ' (the escaped characters)
However, if you contain the string with a different quote type, you don't need to escape:
var string = 'this isn"t a double quoted string';
var string = "this isn't a single quoted string";
// ^ ^ different types, hence we don't need escaping
Like this?
console.log("'{'a'}'")To expand on this, when you are building the string, just use " around the string, and ' within the string.
Having a hard time replicating your issue! See:
var temp = '\'{\'a\'}\'';
console.log('s' + temp + 's');I'd definitely recommend demonstrating the issue you are asking about in a console print or in a readily available editor online before posting a question!
As per your comment, updating to make it part of a variable assignment. Still unclear what the issue is!
Copyvar text = "\"http://example.com\"";
Whatever your text, to wrap it with ", you need to put them and escape inner ones with \. Above will result in:
Copy"http://example.com"
Copyvar text = "http://example.com";
text = "'"+text+"'";
Would attach the single quotes (') to the front and the back of the string.
