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
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.
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!
