I'm doing a function in Jquery and Javascript in which I have to pass a parameter through the url.
This parameter contains the characters / and + , so I have to replace them so that there are no problems in the url.
When using the code:
var selectId = $("#parametroSel").val().replace(/\//g, ":::").replace(/+/g, "::::");
In the javascript console, this error is logged:
SyntaxError: nothing to repeat
What could be the problem?
I have already found the problem, it was here:
replace(/+/g, "::::");
I had to escape the +
replace(/\+/g, "::::");
I know the question is about replace, but I suggest you use a encodeURIComponent() to encode data that you must send in a query string.
The main thing is that it performs standard encoding or URL encoding, which will be easy, even transparent to decode on the server side.
var uri = "http://ejemplo.com/prueba uno.html?symbols=\+:/&";
console.log(
encodeURIComponent(uri)
);
