Encountering an issue:
var test = $("#k_w").val().search("sinh("+parseFloat(sinh_array[i]));
An error message is displayed by the debugger:
Uncaught SyntaxError: Invalid regular expression: /sinh(2/: Unterminated groupsinh_array[i] represents numerical values.
Any ideas on what could be causing this problem?
The String.search function transforms the initial parameter into a Regular expression.
If you need to locate a string without converting it to a RegExp, consider using the String.indexOf method instead.
var test = $("#k_w").val().indexOf("sinh("+parseFloat(sinh_array[i]));
// ^^^^^^^ indexOf
It appears that your regular expression contains an opening parenthesis without a corresponding closing parenthesis.
To properly match the parentheses, you may want to consider using the following revised code:
var test = $("#k_w").val().search("sinh\\("+parseFloat(sinh_array[i]) + "\\)");
It seems like you intend to include the actual parentheses in the search pattern rather than creating a grouping function.
In order to properly use regular expressions, it's important to remember to escape parentheses. If you don't escape them, they will signify the start of a match group and need to be closed again.
var test = $("#k_w").val().search("sinh\\("+parseFloat(sinh_array[i]));
