How to code a formula that will call a variable string that may contain quotation marks?

I'm sorry, I know the issue was addressed before, but I can't make any answer fit my problem...
I am writing a short script on google script, where I want to use the searchFile method on a folder, to look for a file whose name is stored in the string variable Name:
var theFileImLookingFor = theSourceFolder.searchFiles("title = '"+Name+"'").next();
This code works fine as long as the variable Name doesn't include quotation marks. Then, I'm stuck...
Please help me adapt my code :)

A simple but fragile solution could be to use backticks (`), usually found on the upper left of the keyboard on the same key as the tilde (~). These are sort of like quotation marks in javascript, but can also be used in ways that quotation marks can't.
Expect this solution to fail whenever the variable's value contains backticks.

Did you try to escape possible quotes ?
You probably could write a little function that take your variable "name" then escape possible quotes in it before returning it to searchFile. Or maybe with a simple "replace("'", "\'")"...

Javascript replacing double backslashed with single backslash

I have been browsing lots of solutions, but somewhy haven't got anything to work.
I need to replace following string: "i:0#.w|dev\\tauri;" with "i:0#.w|dev\tauri;"
I have tried following JS codes to replace:
s.replace(/\\\\/g, "\\$1");
s.replace(/\\\\/g, "\\");
But have had no result. Yet following replaced my \\ with "
s.replace(/\\/g, "\"");
To be honset, then I am really confused behind this logic, it seems like there should be used \\\\ for double backshashed yet it seems to work with just \\ for two backshashes..
I need to do this for comparing if current Sharepoint user (i:0#.w|dev\tauri) is on the list.
Update:
Okay, after I used console.log();, I discovered something interesting.
Incode: var CurrentUser = "i:0#.w|dev\tauri"; and console.log(): i:0#.w|dev auri...
C# code is following:
SPWeb theSite = SPControl.GetContextWeb(Context);
SPUser theUser = theSite.CurrentUser;
return theUser.LoginName;

JavaScript strings need to be escaped so if you are getting a string literal with two back slashes, JavaScript interprets it as just one. In your string you are using to compare, you have \t, which is a tab character, when what you probably want is \\t. My guess is that wherever you are getting the current SharePoint user from, it is being properly escaped, but your compare list isn't.
Edit:
Or maybe the other way around. If you're using .NET 4+ JavaScriptStringEncode might be helpful. If you're still having problems it might help to show us how you are doing the comparison.

carriage return encoding

through queries to a Database I am retrieving such data that I previously inserted through HTML textarea or input. When I get the response from my DB , in a JSON object the text field looks like this :
obj : {
text : [some_text] ↵ [some_text]
}
I tried to replace with this function :
string_convert = function(string){
return string.replace("&#8629",'<br>')
.replace('&crarr','<br>')
.replace('/[\n\r]/g','<br>');
}
I have to show this string in HTML ,but it does not seems to work. I'm using UTF-8
Any advice?

The problem you have is that you have enclosed your regex in quotes. This is incorrect.
.replace('/[\n\r]/g','<br>');
^ ^
remove these two quotes
The quotes are unnecessary because the regex is already delimited by the slashes.
By putting quotes in there, you've actually told it that you want to replace a fixed string rather than a regular expression. The fixed string may look like an expression, but with the quotes, it will just be seen as a plain string.
Remove the quotes and it will be seen as an expression, and it will work just fine.
One other thing, though -- in order to make your regex work perfectly, I'd also suggest modifying it slightly. As it stands, it will just replace all the \n and \r characters with <br>. But in some cases, they may come together as a \r\n pair. This should be a single line break, but your expression will replace it with two <br>s.
You could use an expression like this instead:
/\r\n|\n|\r/g
Hope that helps.

you are missing the ending semicolons ; in your code:
string_convert = function(aString){
return aString.replace("↵",'<br>').replace('↵','<br>');
}
this does not necessary solve your problem, but it could likely.

From: Trying to translate a carriage return into a html tag in Javascript?
text = text.replace(/(\r\n|\n|\r)/g,"<br />");

Too many quotes within quotes -- what to do?

Here is a section of code used by CKEditor on my website:
CKEDITOR.config.IPS_BBCODE = {"acronym":{"id":"8","title":"Acronym","desc":"Allows you to make an acronym that will display a description when moused over","tag":"acronym","useoption":"1","example":"[acronym='Laugh Out Loud']lol[/acronym]", ...
If you scroll to the right just a little, you will see this:
"[acronym='Laugh Out Loud']lol[/acronym]"
I need to store all of the CKEditor code inside a javascript string, but I can't figure out how to do it because the string has both " and ' in it. See the problem? Furthermore, I don't think I can just escape the quotes because I tried doing that and the editor didn't work.
Any idea what I can do?

You might try taking the string and injecting JavaScript escape codes into it. JavaScript can essentially use any unicode value when using the format: \u#### - so, for a ' character, the code is \u0039, and for the " character, the code is \u0034.
So - you could encode your example portion of the string as:
\u0034[acronym=\u0039Laugh Out Loud\u0039]lol[/acronym]\u0034
Alternatively, you could attempt to simply escape the quotes as in:
\"[acronym=\'Laugh Out Loud\']lol[/acronym]\"
The problem here occurs when you wind up with this kind of situation:
"data:{'prop1':'back\\slash'}"
Which, when escaped in this manner, becomes:
"data:{\'prop\':\'back\\\\slash\'}\"
While this is somewhat more readable than the first version - de-serializing it can be a little tricky when going across object-spaces, such as a javascript object being passed to a C# parser which needs to deserialize into objects, then re-serialize and come back down. Both languages use \ as their escape character, and it is possible to get funky scenarios which are brain-teasers to solve.
The advantage of the \u#### method is that only JavaScript generally uses it in a typical stack - so it is pretty easy to understand what part should be unescaped by what application piece.

hmm.. you said you already tried to escape the quotes and it gave problems.
This shouldn't give problems at all, so try this:
$newstring = addslashes($oldstring);

There's no need to use Unicode escape sequences. Just surround your string with double quotes, and put a backslash before any double quotes within the string.
var x = "\"[acronym='Laugh Out Loud']lol[/acronym]\"";

how to escape JavaScript code in HTML

I have some addHtml JavaScript function in my JS code. I wonder how to escape HTML/JS code properly. Basically, what I am trying right now is:
addHtml("<a onclick=\"alert(\\\"Hello from JS\\\")\">click me</a>")
However, that doesn't work. It adds the a element but it doesn't do anything when I click it.
I don't want to replace all " by ' as a workaround. (If I do, it works.)

I wonder how to escape HTML/JS code properly.
To insert string content into an HTML event handler attribute:
(1) Encode it as a JavaScript string literal:
alert("Hello \"world\"");
(2) Encode the complete JavaScript statement as HTML:
<a onclick="alert("Hello \"world\""">foo</a>
And since you seem to be including that HTML inside a JavaScript string literal again, you have to JS-encode it again:
html= "<a onclick=\"alert("Hello \\"world\\""\">foo<\/a>";
Notice the double-backslashes and also the <\/, which is necessary to avoid a </ sequence in a <script> block, which would otherwise be invalid and might break.
You can make this less bad for yourself by mixing single and double quotes to cut down on the amount of double-escaping going on, but you can't solve it for the general case; there are many other characters that will cause problems.
All this escaping horror is another good reason to avoid inline event handler attributes. Slinging strings full of HTML around sucks. Use DOM-style methods, assigning event handlers directly from JavaScript instead:
var a= document.createElement('a');
a.onclick= function() {
alert('Hello from normal JS with no extra escaping!');
};

My solution would be
addHtml('<a onclick="alert(\'Hello from JS\')">click me</a>')
I typically use single quotes in Javascript strings, and double quotes in HTML attributes. I think it's a good rule to follow.

How about this?
addHtml("<a onclick=\"alert("Hello from JS")\">click me</a>");
It worked when I tested in Firefox, at any rate.

addHtml("<a onclick='alert(\"Hello from JS\")'>click me</a>")

The problem is probably this...
As your code is now, it will add this to the HTML
<a onclick="alert("Hello from Javascript")"></a>
This is assuming the escape slashes will all be removed properly.
The problem is that the alert can't handle the " inside it... you'll have to change those quotes to single quotes.
addHtml("<a onclick=\"alert(\\\'Hello from JS\\\')\">click me</a>")
That should work for you.

What does the final HTML rendered in the browser look like ? I think the three slashes might be causing an issue .
