i have a long String. With some German characters and lots of new lines tabs ect.. In a Selectbox user can select a text, on change i do
document.getElementById('text').value=this.value;
But this fails. I just get a "unterminated string literal" as error in JavaScript.
I think i should clean the string.
How can i do it in JavaScript?
Its not because of that code, there is syntax error somewhere in your javascript file.
For example, in one of your previous question's answer
alert("yes link clicked);
You could see, there is " is missing after clicked, which could cause unterminated string literal error. Fix it like
alert("yes link clicked");
As I cannot judge from your code, you might want to check what this in this.value refers to, e.g. using an alert("debug: " + this.value) .
Other than that, you might want to use encodeURI() for converting umlauts and other special characters to hexadecimal notation. If your page's content-type is set to UTF-8 special characters will then display correctly.
var x = 'hello;will probably give you the same error, because the string doesn't end anywhere, as there is no closing apostrophe, i.e.'.
