Generate a URL string that contains square brackets.

I'm trying to generate a URL string that contains square brackets, but the form removes them after I hit Save.

I am not sure if I have understood your question correctly. Do you mean to say that you are trying to create link by add text in form calculation widget?

Please note that after adding the text in form calculation widget, you need to ensure to click on the text and ensure it is in light brown background. Please check the screenshot below:

I'm trying to populate a field with a string in the form of:

https://mydomain.com/#/x[144.99223]/y[-37.79490]/

I type in the string that I need:

Then I pick the output field or hit Save, and it screws up my string. Note the square brackets are now missing:

The URL I'm trying to construct needs the square brackets, but Jotform doesn't seem to support it.

Please note that you can use URL encoded value in form calculation widget and when you copy paste the encoded value in browser, it will work correctly. Here is the encoded value of the text:

https://mydomain.com/#/x[144.99223]/y[-37.79490]/

/#/x[

%2F%23%2Fx%5B

144.99223

]/y[

%5D%2Fy%5B

-37.79490

]/

%5D%2F

The text with yellow background is the encoded text of the text in bold. Do try it out and get back to us if you have any questions.
