Quoting, editing problems

by Zzbaivong June 25th 2015, 2:52 pm

I have a code:

Code:: var jsCodes = "<img src=\"http://r29.imgfast.net/users/3412/19/22/63/smiles/45347.png\" />";

Note backslash: \"

I can preview and submit without errors. However, when I quote or edit this post, the backslash will disappear. This causes the error to my code.

To test, try quoting this post.

Do you exactly need those in the code?

I don't understand you. I'm reporting a problem in SCEditor.

I mean that I believe you do not need the backlashes?

I think that is not the way to solve the problem. Because my forum is also a lot of other people who also share their code.

The backslash "\" is commonly used in programming as an escape character. With JavaScript it can be used in string literals to use the same kind of quotation marks inside it without ending the string.

Example :

Code:: var str = 'Let's go to the park!'; // syntax error

The string ended before "s", because the quotation mark was recognized as the end of the string literal. Using the escape character gets passed this problem.

Code:: var str = 'Let\'s go to the park!'; // All good :)

Into the topic.. That's a problem, but for the moment I'd recommend using a different kind of quote for the attributes, such as the single.

Code:: var jsCodes = "<img src='http://r29.imgfast.net/users/3412/19/22/63/smiles/45347.png' />";

or swap it :

Code:: var jsCodes = '<img src="http://r29.imgfast.net/users/3412/19/22/63/smiles/45347.png" />';

I know that. Thanks for your enthusiasm.

The explanation on the backslash wasn't directed towards you. Dawa

From what I can tell, the backslash in my post didn't disappear. I'm assuming it's only with certain characters ? ( i.e. double quote ) I'm just going to leave a few test below to see.

Code:: "<div id=\"noId\"></div>"; "A \"normal\" string."; '<div id=\'noId\'></div>'; 'A \'normal\' string.';
