Error using Javascript and JSP, string with space gives `Unterminated string literal`

Question

I have to pass a string value to JavaScript from JSP page.
I am using

display("<%=name%>")

It works fine but when i have string like 'sweet milk' , JavaScript throws the error

Unterminated string literal

How to solve this?

Answer 1

您的字符串包含单引号-您可以将单引号转义为“ \\ x27”，将双引号转义为“ \\ x22”，然后将其传递给javascript。

Answer 2

You probably have characters in your String that should be escaped in Javascript. For example, if your string is My name is "John" , your code will generate

var a = "My name is "John"";

which is invalid.

You should use StringEscapeUtils.escapeJavaScript from commons-lang to make sure everything is correctly escaped (single and double quotes, newlines, tabs, etc.).

Answer 3

I guess there's an error in the generated JavaScript code. Is there any way to look at you page? I suggest to look at the generated source code of that page.
